sun4v nexus(4) in turn is based on):
o Change nexus(4) to manage the resources of its children so the
respective device drivers don't need to figure them out of OFW
themselves.
o Change nexus(4) to provide the ofw_bus KOBJ interface instead of
using IVARs for supplying the OFW node and the subset of standard
properties of its children. Together with the previous change this
also allows to fully take advantage of newbus in that drivers like
fhc(4), which attach on multiple parent busses, no longer require
different bus front-ends as obtaining the OFW node and properties
as well as resource allocation works the same for all supported
busses. As such this change also is part 4/4 of allowing creator(4)
to work in USIII-based machines as it allows this driver to attach
on both nexus(4) and upa(4). On the other hand removing these IVARs
breaks API compatibility with the powerpc nexus(4) but which isn't
that bad as a) sparc64 currently doesn't share any device driver
hanging off of nexus(4) with powerpc and b) they were no longer
compatible regarding OFW-related extensions at the pci(4) level
since quite some time.
o Provide bus_get_dma_tag methods in nexus(4) and its children in
order to handle DMA tags in a hierarchical way and get rid of the
sparc64_root_dma_tag kludge. Together with the previous two items
this changes also allows to completely get rid of the nexus(4)
IVAR interface. It also includes:
- pushing the constraints previously specified by the nexus_dmatag
down into the DMA tags of psycho(4) and sbus(4) as it's their
IOMMUs which induce these restrictions (and nothing at the
nexus(4) or anything that would warrant specifying them there),
- fixing some obviously wrong constraints of the psycho(4) and
sbus(4) DMA tags, which happened to not actually be used with
the sparc64_root_dma_tag kludge in place and therefore didn't
cause problems so far,
- replacing magic constants for constraints with macros as far
as it is obvious as to where they come from.
This doesn't include taking advantage of the newbus way to get
the parent DMA tags implemented by this change in order to divorce
the IOTSBs of the PCI and SBus IOMMUs or for implementing the
workaround for the DMA sync bug in Sabre (and Tomatillo) bridges,
yet, though.
o Get rid of the notion that nexus(4) (mostly) reflects an UPA bus
by replacing ofw_upa.h and with ofw_nexus.h (which was repo-copied
from ofw_upa.h) and renaming its content, which actually applies to
all of Fireplane/Safari, JBus and UPA (in the host bus case), as
appropriate.
o Just use M_DEVBUF instead of a separate M_NEXUS malloc type for
allocating the device info for the children of nexus(4). This is
done in order to not need to export M_NEXUS when deriving drivers
for subordinate busses from the nexus(4) class.
o Use the DEFINE_CLASS_0() macro to declare the nexus(4) driver so
we can derive subclasses from it.
o Const'ify the nexus_excl_name and nexus_excl_type arrays as well
as add 'associations' and 'rsc', which are pseudo-devices without
resources and therefore of no real interest for nexus(4), to the
former.
o Let the nexus(4) device memory rman manage the entire 64-bit address
space instead of just the UPA_MEMSTART to UPA_MEMEND subregion as
Fireplane/Safari- and JBus-based machines use multiple ranges,
which can't be as easily divided as in the case of UPA (limiting
the address space only served for sanity checking anyway).
o Use M_WAITOK instead of M_NOWAIT when allocating the device info
for children of nexus(4) in order to give one less opportunity
for adding devices to nexus(4) to fail.
o While adapting the drivers affected by the above nexus(4) changes,
change them to take advantage of rman_get_rid() instead of caching
the RIDs assigned to allocated resources, now that the RIDs of
resources are correctly set.
o In iommu(4) and nexus(4) replace hard-coded functions names, which
actually became outdated in several places, in panic strings and
status massages with __func__. [1]
o Use driver_filter_t in prototypes where appropriate.
o Add my copyright to creator(4), fhc(4), nexus(4), psycho(4) and
sbus(4) as I changed considerable amounts of these drivers as well
as added a bunch of new features, workarounds for silicon bugs etc.
o Fix some white space nits.
Due to lack of access to Exx00 hardware, these changes, i.e. central(4)

retry the command. This leads to undesirable cycling of the camisr as well as
a high possibility for the command to exhaust its retries before the driver
can get around to servicing it.
The better fix, as demonstrated here, is to freeze the simq and mark the
command as needing to be tried. Then when driver can service the command,
the simq gets unfrozen. This is correct, and documented here to help reduce
the mystery. However, it also points out a shortcoming in CAM error handling
that makes writing drivers harder.

a version that i posted earlier on the -current mailing list,
and subsequent feedback received.
The core of the change is just in sys/firmware.h and kern/subr_firmware.c,
while other files are just adaptation of the clients to the ABI change
(const-ification of some parameters and hiding of internal info,
so this is fully compatible at the binary level).
In detail:
- reduce the amount of information exported to clients in struct firmware,
and constify the pointer;
- internally, document and simplify the implementation of the various
functions, and make sure error conditions are dealt with properly.
The diffs are large, but the code is really straightforward now (i hope).
Note also that there is a subtle issue with the implementation of
firmware_register(): currently, as in the previous version, we just
store a reference to the 'imagename' argument, but we should rather
copy it because there is no guarantee that this is a static string.
I realised this while testing this code, but i prefer to fix it in
a later commit -- there is no regression with respect to the past.
Note, too, that the version in RELENG_6 has various bugs including
missing locks around the module release calls, mishandling of modules

- First off, device drivers really do need to know if they are allocating
MSI or MSI-X messages. MSI requires allocating powerof2() messages for
example where MSI-X does not. To address this, split out the MSI-X
support from pci_msi_count() and pci_alloc_msi() into new driver-visible
functions pci_msix_count() and pci_alloc_msix(). As a result,
pci_msi_count() now just returns a count of the max supported MSI
messages for the device, and pci_alloc_msi() only tries to allocate MSI
messages. To get a count of the max supported MSI-X messages, use
pci_msix_count(). To allocate MSI-X messages, use pci_alloc_msix().
pci_release_msi() still handles both MSI and MSI-X messages, however.
As a result of this change, drivers using the existing API will only
use MSI messages and will no longer try to use MSI-X messages.
- Because MSI-X allows for each message to have its own data and address
values (and thus does not require all of the messages to have their
MD vectors allocated as a group), some devices allow for "sparse" use
of MSI-X message slots. For example, if a device supports 8 messages
but the OS is only able to allocate 2 messages, the device may make the
best use of 2 IRQs if it enables the messages at slots 1 and 4 rather
than default of using the first N slots (or indicies) at 1 and 2. To
support this, add a new pci_remap_msix() function that a driver may call
after a successful pci_alloc_msix() (but before allocating any of the
SYS_RES_IRQ resources) to allow the allocated IRQ resources to be
assigned to different message indices. For example, from the earlier
example, after pci_alloc_msix() returned a value of 2, the driver would
call pci_remap_msix() passing in array of integers { 1, 4 } as the
new message indices to use. The rid's for the SYS_RES_IRQ resources
will always match the message indices. Thus, after the call to
pci_remap_msix() the driver would be able to access the first message
in slot 1 at SYS_RES_IRQ rid 1, and the second message at slot 4 at
SYS_RES_IRQ rid 4. Note that the message slots/indices are 1-based
rather than 0-based so that they will always correspond to the rid
values (SYS_RES_IRQ rid 0 is reserved for the legacy INTx interrupt).
To support this API, a new PCIB_REMAP_MSIX() method was added to the
pcib interface to change the message index for a single IRQ.

which at that time had a mainbus(4) (for USI/II machines, which use
an UPA interconnection bus as the nexus) and an upa(4) (for USIII
machines, which use a subordinate/slave UPA bus hanging off from the
Fireplane/Safari interconnection bus) front-end. With FreeBSD and
newbus there is/will be no need to have two separate bus front-ends
for these busses, so we can easily coallapse the shared front-end
and the back-end into a single source file (note that the FreeBSD
creator_upa.c was misnomer anyway; based on what it actually attached
to that should have been creator_nexus.c), actually OpenBSD meanwhile
also has moved to a shared front-end and a single source file. Due
to the low-level console support creator.c also wasn't free from bus
related things before.
While at it, also split sys/sparc64/creator/creator.h into a
sys/dev/fb/creatorreg.h that only contains register macros and move
the structures to the top of sys/dev/fb/creator.c as suggested by
style(9) so creator(4) is no longer scattered over two directories.
- Use OF_decode_addr()/sparc64_fake_bustag() to obtain the bus tags and
handles for the low-level console support instead of hardcoding
support for AFB/FFB hanging off from nexus(4) only. This is part 2/4
of allowing creator(4) to work in USIII machines (which have a UPA
bus hanging off from the Fireplane/Safari bus reflected by the nexus),
which already makes it work as the low-level console there.
- Allocate resources in the bus attach routine regardless of whether
creator(4) is used as for the low-level console and thus the required
bus tags and handles have been already obtained or not so the resources
are marked as taken in the respective RMAN.
- For both obtaining the bus tags and handles for the low-level console
support as well as allocating the corresponding resources in the
regular bus attach routine don't bother to get all for the maximum of
24 register banks but only (for) the two tag/handle pairs required for
providing the video interface for syscons(4) support. If we can't
allocate the rest of them just limit the memory range accessible via
creator_fb_mmap() accordingly.
- Sanity check the memory range spanned by the first and last resources
and the resources in between as far as possible, as the XFree86/Xorg
sunffb(4) expects to be able to access the whole region, even though
the backing resources are actually non-continuous. Limit and check
the memory range accessible via creator_fb_mmap() accordingly.
- Reduce the size of buffers for OFW properties to what they actually
need to hold.
- Rename some tables to creator_<foo> for consistency.
- Also for the sizes in the creator_fb_mmap() mapping table entries use
macros for consistency, add macros for the remaining register banks
for completeness.
operation as it ran out of free descriptors or if there are too many
segments in the first place, call bus_dmamap_unload() in order to
unload the already loaded segments.
For trying to map the defragmented mbuf (chain) in re_encap() this
introduces re_dma_map_desc() setting arg.rl_maxsegs to 0 as a new
failure mode. Previously we just ignored this case, corrupting our
view of the TX ring.
o In re_txeof():
- Don't clear IFF_DRV_OACTIVE unless there are at least 4 free TX
descriptors. Further down the road re_encap() will bail if there
aren't at least 4 free TX descriptors, causing re_start() to
abort and prepend the dequeued mbuf again so it makes no sense
to pretend we could process mbufs again when in fact we won't.
While at it replace this magic 4 with a macro RL_TX_DESC_THLD
throughout this driver.
- Don't cancel the watchdog timeout as soon as there's at least one
free TX descriptor but instead only if all descriptors have been
handled. It's perfectly normal, especially in the DEVICE_POLLING
case, that re_txeof() is called when only a part of the enqueued
TX descriptors have been handled, causing the watchdog to be
disarmed prematurely.
o In re_encap():
- If m_defrag() fails just drop the packet like other NIC drivers
do. This should only happen when there's a mbuf shortage, in which
case it was possible to end up with an IFQ full of packets which
couldn't be processed as they couldn't be defragmented as they
were taking up all the mbufs themselves. This includes adjusting
re_start() to not trying to prepend the mbuf (chain) if re_encap()
has freed it.
- Remove dupe initialization of members of struct rl_dmaload_arg to
values that didn't change since trying to process the fragmented
mbuf chain.
While at it remove an unused member from struct rl_dmaload_arg.
o In re_start() remove a abandoned, banal comment. The corresponding
code was moved to re_attach() some time ago.
With these changes re(4) now survives one day (until stopped) of
hammering out packets here.

- Parse the _CST packages for each cpu and track all the states individually,
on a per-cpu basis.
- Revert to generic FADT/P_BLK based Cx control if the _CST package
is not present on all cpus. In that case, the new driver will
still support per-cpu Cx state handling. The driver will determine the
highest Cx level that can be supported by all the cpus and configure the
available Cx state based on that.
- Fixed the case where multiple cpus in the system share the same
registers for Cx state handling. To do that, added a new flag
parameter to the acpi_PkgGas and acpi_bus_alloc_gas functions that
enable the caller to add the RF_SHAREABLE flag. This flag could also be
useful to other callers (acpi_throttle?) in the tree but this change is
not yet made.
- For Core Duo cpus, both cores seems to be taken out of C3 state when
any one of the cores need to transition out. This broke the short sleep
detection logic. It is disabled now if there is more than one cpu in
the system for now as it fixed it in my case. This quirk may need to
be re-enabled later differently.
- Added support to control cx_lowest on a per-cpu basis. There is still

New features:
1. Optional multichannel recording (32 channels on Live!, 64 channels
on Audigy).
All channels are 16bit/48000Hz/mono, format is fixed.
Half of them are copied from sound output, another half can be
used to record any data from DSP. What should be recorded is
hardcoded in DSP code. In this version it records dummy data, but
can be used to record all DSP inputs, for example..
Because there are no support of more-than-stereo sound streams
multichannell stream is presented as one 32(64)*48000 Hz 16bit mono
stream.

The problem was that I was acquiring the driver sx lock and then waiting
for a taskqueue to drain, however the taskqueue itself would try to
acquire the lock as well leading to a deadlock.
To fix the problem roll my own exclusive lock that allows for lock
cancellation. This is a normal exclusive lock, however if someone
marks it as "dead" then all waiters who request an error return will
get back an error instead of continuing to wait for the lock.
In this particular case, the shutdown and detach functions kill the
lock while the async task thread tries to acquire the lock but will
abort if the lock returns an error.
The other option was to drop the driver lock mid-detach and mid-shutdown,
mid-detach was a ok, however mid-shutdown was not.

been handled instead of when at least one descriptor was just handled.
For bge, it is normal to get a txeof when only a small fraction of the
queued tx descriptors have been handled, so the bug broke the watchdog
in a usual case.
- moved the synchronizing bus read to after the bus write for the first
interrupt ack so that it actually synchronizes everything necessary.
We were acking not only the status update that triggered the interrupt
together with any status updates that occurred before we got around
to the bus write for the ack, but also any status updates that occur
after we do the bus write but before the write reaches the device.
The corresponding race for the second interrupt ack resulted in
sometimes returning from the interrupt handler with acked but
unserviced interrupt events. Such events then remain unserviced
until further events cause another interrupt or the watchdog times
out.
The race was often lost on my 5705, apparently since my 5705 has broken
event coalescing which causes a status update for almost every packet,
so another status update is quite likely to occur while the interrupt
handler is running. Watchdog timeouts weren't very noticeable,
apparently because bge_txeof() has one of the usual bugs resetting the
watchdog.
- don't disable device interrupts while bge_intr() is running. Doing this
just had the side effects of:
- entering a device mode in which different coalescing parameters apply.
Different coalescing parameters can be used to either inhibit or
enhance the chance of getting another status update while in the
interrupt handler. This feature is useless with the current
organization of the interrupt handler but might be useful with a
taskqueue handler.
- giving a race for ack+reenable/return. This cannot be handled
by simply rearranging the order of bus accesses like the race for
ack+keepenable/entry. It is necessary to sync the ack and then
check for new events.
- taking longer, especially with the extra code to avoid the race on
ack+reenable/return.

- Correct RX packet drop counter for BCM5705+. This register is read/clear
and it wraps very quickly under heavy packet drops because only the lower
ten bits are valid according to the documentation. However, it seems few
more bits are actually valid and the rest bits are always zeros[1].
Therefore, we don't mask them off here. To get accurate packet drop count,
we need to check the register from bge_rxeof(). It is commented out for now,
not to penalize normal operation. Actual performance impact should be
measured later.
- Correct integer casting from u_long to uint32_t. Casting is not really
needed for all supported platforms but we better do this correctly[2].

off of 24XX to be gated off of 2K login support. Convert some
isp_prt calls to xpt_print calls.
Add a note that suggests a cleanup.
Note: This patch was derived based on looking at the pvrxxx/pvr250

anything I saw from Hauppage.
- In hme_eint() print MIF register contents on MIF interrupts.
- In hme_mifinit() don't bother to preserve the previous MIF config.
This was mainly done in order to preserve the PHY select bit (external
or internal PHY) but which only needs to be set as appropriate when
reading from or writing to the desired PHY in hme_mii_{read,write}reg().
Similarly don't bother to set the PHY select bit in hme_mii_statchg().
- In hme_mii_{read,write}reg() ignore requests to PHYs other than the
external and internal PHY one.
- Move enabling/disabling the MII drivers of the external transceiver
from hme_init_locked() and based on the sheer presence of an external
to hme_mifinit() and based on the currently selected media, defaulting
to the internal transceiver when the media hasn't been set, yet.
Invoke hme_mifinit() from the newly added hme_mediachange_locked() so
the setting of the MII drivers is updated when changing media.
These changes keep the MII bus from wedging (which manifests in the HME
and the PHYs no longer being able to communicate with each other) when
the PHY device drivers isolate the unused PHY in two-PHY configurations
as present in f.e. Netra t1 100 while changing media, either from
hme_init_locked() (see also below) or via ifconfig(8). They also allow
for using both transceivers/PHYs.
- In the newly added hme_mediachange_locked() also reset the PHYs in two-
PHY configurations before invoking mii_mediachg(). This is required
for successfully unisolating the previously unused PHY when switching
between PHYs.
- Now that changing media should no longer cause problems back out rev.
1.27 and re-enable setting the current media in hme_init_locked() (see
the commit message of rev. 1.23 for more info).
These changes are roughly a merge of NetBSD gem.c rev. 1.32 - 1.35 (1.30
was already fixed differently in our 1.36; 1.31 and 1.32 were wrong) with
some parts reworked and things that don't make sense like setting the MII
drivers and restoring the previous MIF and XIF settings in hme_mii_{read,

negotiation cycle as part of the reset.
2) During reset and auto-negotiation, the BMCR will clear the reset

- Multichannel safe, endian safe, format safe
* Large part of critical pcm filters such as vchan.c, feeder_rate.c,
feeder_volume.c, feeder_fmt.c and feeder.c has been rewritten so that
using them does not cause the pcm data to be converted to 16bit little
endian.
* Macrosses for accessing pcm data safely are defined within sound.h in
the form of PCM_READ_* / PCM_WRITE_*
* Currently, most of them are probably limited for mono/stereo handling,
but the future addition of true multichannel will be much easier.
- Low latency operation
* Well, this require lot more works to do not just within sound driver,
but we're heading towards right direction. Buffer/block sizing within
channel.c is rewritten to calculate precise allocation for various
combination of sample/data/rate size. As a result, applying correct
SNDCTL_DSP_POLICY value will achive expected latency behaviour simmilar
to what commercial 4front driver do.
* Signal handling fix. ctrl+c of "cat /dev/zero > /dev/dsp" does not
result long delay.
* Eliminate sound truncation if the sound data is too small.

it is used for transfers that move data from USB to PC. But
someone forgot that control transfers consist of possibly two
data chunks : the request itself and optionally a buffer of
data that should be transfered to or from the USB device. On
requests to the control endpoint without additional data
bus_dmamap_sync() didn't get called. For some reason my first

- Add 3 new functions to the pci_if interface along with suitable wrappers
to provide the device driver visible API:
- pci_alloc_msi(dev, int *count) backed by PCI_ALLOC_MSI(). '*count'
here is an in and out parameter. The driver stores the desired number
of messages in '*count' before calling the function. On success,
'*count' holds the number of messages allocated to the device. Also on
success, the driver can access the messages as SYS_RES_IRQ resources
starting at rid 1. Note that the legacy INTx interrupt resource will
not be available when using MSI. Note that this function will allocate
either MSI or MSI-X messages depending on the devices capabilities and
the 'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. Also note
that the driver should activate the memory resource that holds the
MSI-X table and pending bit array (PBA) before calling this function
if the device supports MSI-X.
- pci_release_msi(dev) backed by PCI_RELEASE_MSI(). This function
releases the messages allocated for this device. All of the
SYS_RES_IRQ resources need to be released for this function to succeed.
- pci_msi_count(dev) backed by PCI_MSI_COUNT(). This function returns
the maximum number of MSI or MSI-X messages supported by this device.
MSI-X is preferred if present, but this function will honor the
'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. This function
should return the largest value that pci_alloc_msi() can return
(assuming the MD code is able to allocate sufficient backing resources
for all of the messages).
- Add default implementations for these 3 methods to the pci_driver generic
PCI bus driver. (The various other PCI bus drivers such as for ACPI and
OFW will inherit these default implementations.) This default
implementation depends on 4 new pcib_if methods that bubble up through
the PCI bridges to the MD code to allocate IRQ values and perform any
needed MD setup code needed:
- PCIB_ALLOC_MSI() attempts to allocate a group of MSI messages.
- PCIB_RELEASE_MSI() releases a group of MSI messages.
- PCIB_ALLOC_MSIX() attempts to allocate a single MSI-X message.
- PCIB_RELEASE_MSIX() releases a single MSI-X message.
- Add default implementations for these 4 methods that just pass the
request up to the parent bus's parent bridge driver and use the
default implementation in the various MI PCI bridge drivers.
- Add MI functions for use by MD code when managing MSI and MSI-X
interrupts:
- pci_enable_msi(dev, address, data) programs the MSI capability address
and data registers for a group of MSI messages
- pci_enable_msix(dev, index, address, data) initializes a single MSI-X
message in the MSI-X table
- pci_mask_msix(dev, index) masks a single MSI-X message
- pci_unmask_msix(dev, index) unmasks a single MSI-X message
- pci_pending_msix(dev, index) returns true if the specified MSI-X
message is currently pending
- Save the MSI capability address and data registers in the pci_cfgreg
block in a PCI devices ivars and restore the values when a device is

- Add an option SUNKBD_EMULATE_ATKBD whose code is based on the respective
code in ukbd(4) and like UKBD_EMULATE_ATSCANCODE causes this driver to
emit AT keyboard/KB_101 compatible scan codes in K_RAW mode as assumed by
kbdmux(4). Unlike UKBD_EMULATE_ATSCANCODE, SUNKBD_EMULATE_ATKBD also
triggers the use of AT keyboard maps and thus allows to use the map files
in share/syscons/keymaps with this driver at the cost of an additional
translation (in ukbd(4) this just is the way of operation).
- Implement an option SUNKBD_DFLT_KEYMAP, which like the equivalent options
of the other keyboard drivers allows to specify the default in-kernel
keyboard map. For obvious reasons this made to only work when also using
SUNKBD_EMULATE_ATKBD.
- Implement sunkbd_check(), sunkbd_check_char() and sunkbd_clear_state(),
which are also required for interoperability with kbdmux(4).
- Implement K_CODE mode and FreeBSD keypad compose.
- As a minor hack define KBD_DFLT_KEYMAP also in the !SUNKBD_EMULATE_ATKBD
case so we can obtain fkey_tab from <dev/kbd/kbdtables.h> rather than
having to duplicate it and #ifdef some more code.
- Don't use the TX-buffer for writing the two command bytes for setting the
keyboard LEDs as this consequently requires a hardware FIFO that is at
least two bytes in depth, which the NMOS-variant of the Zilog SCCs doesn't
have. Thus use an inlined version of uart_putc() to consecutively write
the command bytes (a cleaner approach would be to do this via the soft

keyboard is attached only after the system has already booted.
If USB keyboard is also present, and there's no kbdmux(4), the problem
has been hiding itself because as soon as we get to multi-user, the
USB keyboard becomes an active keyboard (see devd.conf), thus marking
atkbd inactive and letting the old code initialize the keyboard.
With kbdmux(4), or if there's no USB keyboard, the atkbd keyboard is
always active, whether it's physically attached or not, thus it never
initialized itself properly on a physical attach.
To fix this, move block that initialized the keyboard on attach upper
so it doesn't depend on the (KBD_IS_ACTIVE(kbd) && KBD_IS_BUSY(kbd))
condition. Also move KBD_FOUND_DEVICE() a few lines upper so that

The goal was to sync with the OSSv4 API 4Front Technologies uses in their
proprietary OSS driver. This was successful as far as possible. The part
of the API which is stable is implemented, for the rest there are some
stubs already.
New system ioctls:
- SNDCTL_SYSINFO - obtain audio system info (version, # of audio/midi/
mixer devices, etc.)
- SNDCTL_AUDIOINFO - fetch details about a specific audio device
- SNDCTL_MIXERINFO - fetch details about a specific mixer device
New audio ioctls:
- Sync groups (SNDCTL_DSP_SYNCGROUP/SNDCTL_DSP_SYNCSTART) which allow
triggered playback/recording on multiple devices (even across processes
simultaneously).
- Peak meters (SNDCTL_DSP_GETIPEAKS/SNDCTL_DSP_GETOPEAKS) - can query
audio drivers for peak levels (needs driver support, disabled for now).
- Per channel playback/recording levels -
SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL. Note that these are still in name
only, just wrapping around the AC97-style mixer at the moment. The next
step is to push them down to the drivers.
Audio ioctls still under development by 4Front (for which stubs may exist
in this commit):
- SNDCTL_GETNAME, SNDCTL_{GET,SET}{SONG,LABEL}
- SNDCTL_DSP_{GET,SET}_CHNORDER
- SNDCTL_MIX_ENUMINFO, SNDCTL_MIX_EXTINFO - (might be documented enough in
the OSS releases to work on this. These ioctls cover the cool "twiddle
any knob on your card" features.)
Missing:
- SNDCTL_DSP_COOKEDMODE -- this ioctl is used to give applications direct
access to a card's buffers, bypassing the feeder architecture. It's
a toughy -- "someone" needs to decide :
(a) if this is desireable, and (b) if it's reasonably feasible.
Updates for driver writers:
So far, only two routines to the channel class (in channel_if.m) are added.
One is for fetching a list of discrete supported playback/recording rates
of a channel, and the other is for fetching peak level info (useful for
drawing peak meters). Interested parties may want to help pushing down
SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL into the drivers.

- Change smbus_callback() to pass a void * rather than caddr_t.
- Change smbus_bread() to pass a pointer to the count and have it be an
in/out parameter. The input is the size of the buffer (same as before),
but on return it will contain the actual amount of data read back from
the bus. Note that this value may be larger than the input value. It
is up to the caller to treat this as an error if desired.
- Change the SMB_BREAD ioctl to write out the updated struct smbcmd which
will contain the actual number of bytes read in the 'count' field. To
preserve the previous ABI, the old ioctl value is mapped to SMB_OLD_BREAD
which doesn't copy the updated smbcmd back out to userland. I doubt anyone
actually used the old BREAD anyway as it was rediculous to do a bulk-read
but not tell the using program how much data was actually read.
- Make the smbus driver and devclass public in the smbus module and
push all the DRIVER_MODULE()'s for attaching the smbus driver to
various foosmb drivers out into the foosmb modules. This makes all
the foosmb logic centralized and allows new foosmb modules to be
self-contained w/o having to hack smbus.c everytime a new smbus driver
is added.
- Add a new SMB_EINVAL error bit and use it in place of EINVAL to return

- Map SMB bus error bits to EIO in smbus_error().
- Make the smbus driver call bus_generic_probe() and require child drivers
such as smb(4) to create device_t's via identify routines. Previously,
smbus just created one anonymous device during attach, and if you had
multiple drivers that could attach it was just random chance as to which
driver got to probe for the sole device_t first.
- Add a mutex to the smbus(4) softc and use it in place of dummy splhigh()
to protect the 'owner' field and perform necessary synchronization for
smbus_request_bus() and smbus_release_bus().
- Change the bread() and bwrite() methods of alpm(4), amdpm(4), and
viapm(4) to only perform a single transaction and not try to use a
loop of multiple transactions for a large request. The framing and
commands to use for a large transaction depend on the upper-layer
protocol (such as SSIF for IPMI over SMBus) from what I can tell, and the
smb(4) driver never allowed bulk read/writes of more than 32-bytes
anyway. The other smb drivers only performed single transactions.

additional parameter (relative to pmap_mapdev()) specifying the cache
mode for this mapping. Note that on amd64 only WB mappings are done with
the direct map, all other modes result in a private mapping.
- pmap_mapdev() on i386 and amd64 now defaults to using UC (uncached)
mappings rather than WB. Previously we relied on the BIOS setting up
MTRR's to enforce memio regions being treated as UC. This might make
hw.cbb_start_memory unnecessary in some cases now for example.

- Change the workaround for the autopad/checksum offload bug so that

This approach also gives us a chance to zero the pad space to avoid
possibly leaking data.
- With the PCIe devices, it looks issuing a TX command while there's
already a transmission in progress doesn't have any effect. In other
words, if you send two packets in rapid succession, the second one may
end up sitting in the TX DMA ring until another transmit command is
issued later in the future. Basically, if re_txeof() sees that there
are still descriptors outstanding, it needs to manually resume the
TX DMA channel by issuing another TX command to make sure all
transmissions are flushed out. (The PCI devices seem to keep the
TX channel moving until all descriptors have been consumed. I'm not
sure why the PCIe devices behave differently.)
(You can see this issue if you do the following test: plug an re(4)
interface into another host via crossover cable, and from the other
host do 'ping -c 2 <host with re(4) NIC>' to prime the ARP cache,
then do 'ping -c 1 -s 1473 <host with re(4) NIC>'. You're supposed
to see two packets sent in response, but you may only see one. If
you do 'ping -c 1 -s 1473 <host with re(4) NIC>' again, you'll
see two packets, but one will be the missing fragment from the last
ping, followed by one of the fragments from this ping.)
- Add the PCI ID for the US Robotics 997902 NIC, which is based on
the RTL8169S.
- Add a tsleep() of 1 second in re_detach() after the interrupt handler
is disconnected. This should allow any tasks queued up by the ISR
to drain. Now, I know you're supposed to use taskqueue_drain() for
this, but something about the way taskqueue_drain() works with
taskqueue_fast queues doesn't seem quite right, and I refuse to be
tricked into fixing it.
- Correct the PCI ID for the 8169SC/8110SC in the device list (I added
the macro for it to if_rlreg.h before, but forgot to use it.)
- Remove the extra interrupt spinlock I added previously. After giving it
some more thought, it's not really needed.
- Work around a hardware bug in some versions of the 8169. When sending
very small IP datagrams with checksum offload enabled, a conflict can
occur between the TX autopadding feature and the hardware checksumming
that can corrupt the outbound packet. This is the reason that checksum
offload sometimes breaks NFS: if you're using NFS over UDP, and you're
very unlucky, you might find yourself doing a fragmented NFS write where
the last fragment is smaller than the minimum ethernet frame size (60
bytes). (It's rare, but if you keep NFS running long enough it'll
happen.) If checksum offload is enabled, the chip will have to both
autopad the fragment and calculate its checksum header. This confuses
some revs of the 8169, causing the packet that appears on the wire
to be corrupted. (The IP addresses and the checksum field are mangled.)
This will cause the NFS write to fail. Unfortunately, when NFS retries,
it sends the same write request over and over again, and it keeps
failing, so NFS stays wedged.
(A simple way to provoke the failure is to connect the failing system
to a network with a known good machine and do "ping -s 1473 <badhost>"
from the good system. The ping will fail.)
Someone had previously worked around this using the heavy-handed
approahch of just disabling checksum offload. The correct fix is to
manually pad short frames where the TCP/IP stack has requested
checksum offloading. This allows us to have checksum offload turned
on by default but still let NFS work right.

we would attach streams state data to it and change f_ops of the
associated struct file while it was in use. The latter was especially
not safe, and if a program wants a stream object it should open it via
the streams device anyway.
- Don't bother locking so_emuldata in the streams code now that we only
touch it right after creating a socket (in streamsopen()) or when
tearing it down when the file is closed.
- Remove D_NEEDGIANT from the streams device as it is no longer needed.
renegotiation, we only initialize the hardware only when it is
absolutely required. Process SIOCGIFADDR ioctl in em(4) when we know
an IPv4 address is added. Handling SIOCGIFADDR in a driver is
layering violation but it seems that there is no easy way without
rewritting hardware initialization code to reduce settle time after
reset.
This should fix a long standing bug which didn't send ARP packet when
interface address is changed or an alias address is added. Another
effect of this fix is it doesn't need additional delays anymore when
adding an alias address to the interface.
While I'm here add a new if_flags into softc which remembers current
prgroammed interface flags and make use of it when we have to program

loading for the QLogic cards.
Because isp(4) exists before the root is mounted, it's not really
possible for us to use the kernel's linker to load modules directly
from disk- that's really too bad.
However, the this is still a net win in in that the firmware has
been split up on a per chip (and in some cases, functionality)
basis, so the amount of stuff loaded *can* be substantially less
than the 1.5MB of firmware images that ispfw now manages. That is,
each specific f/w set is now also built as a module. For example,
QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080
firmware is built as isp_1080_it.ko.
For compatibility purposes (i.e., to perturb folks the least), we
also still build all of the firmware as one ispfw.ko module.
This allows us to let 'ispfw_LOAD' keep on working in existing
loader.conf files. If you now want to strip this down to just
the firmware for your h/w, you can then change loader.conf to
load the f/w you specifically want.
We also still allow for ispfw to be statically built (e.g., for
PAE and sparc64).
Future changes will look at f/w unloading and also role switching
that then uses the kernel linker to load different ips f/w sets.

cards: the chips are all marked "RTL8111B", but they put stickers on the
back that say "RTL8168B/8111B". The manual says there's only one HWREV code
for both the 8111B and 8168B devices, which is 0x30000000, but the cards
they sent me actually report HWREV of 0x38000000. Deciding to trust the
hardware in front of me rather than a possibly incorrect manual (it wouldn't
be the first time the HWREVs were incorrectly documented), I changed the
8168 revision code. It turns out this was a mistake though: 0x30000000
really is a valid for the 8168.
There are two possible reasons for there to be two different HWREVs:
1) 0x30000000 is used only for the 8168B and 0x38000000 is only for
the 8111B.
2) There were 8111/8168 rev A devices which both used code 0x30000000,
and the 8111B/8168B both use 0x38000000.
The product list on the RealTek website doesn't mention the existence of
any 8168/8111 rev A chips being in production though, and I've never seen
one, so until I get clarification from RealTek, I'm going to assume that
0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only.
So, the HWREV code for the 8168 has been put back to 0x30000000,
a new 8111 HWREV code has been added, and there are now separate
entries for recognizing both devices in the device list. This will

SK-NET GENESIS document says reading SK_ISSR should stop generating
further interrupts(Since we drop a driver lock before invoking
ifp->if_input handler we should disable interrupts in ISR in order
to protect integrity of softc from subsequent interrupts). But it
seems that there is possibility of loosing interrupts between
reading SK_ISSR and determining which interrupts are reported.
To cope with the situation we continuously read SK_ISSR register
until there are no interrupts. However, it seems that the above
work around doesn't fix all cases. To protect watchdog handler
from triggering false alarm add a work around code which try to
reclaim pending Tx descriptors before resetting hardware. This
should fix occasional watchdog timeout errors seen on this driver.

(1) bpf peer attaches to interface netif0
(2) Packet is received by netif0
(3) ifp->if_bpf pointer is checked and handed off to bpf
(4) bpf peer detaches from netif0 resulting in ifp->if_bpf being
initialized to NULL.
(5) ifp->if_bpf is dereferenced by bpf machinery
(6) Kaboom
This race condition likely explains the various different kernel panics
reported around sending SIGINT to tcpdump or dhclient processes. But really
this race can result in kernel panics anywhere you have frequent bpf attach
and detach operations with high packet per second load.
Summary of changes:
- Remove the bpf interface's "driverp" member
- When we attach bpf interfaces, we now set the ifp->if_bpf member to the
bpf interface structure. Once this is done, ifp->if_bpf should never be
NULL. [1]
- Introduce bpf_peers_present function, an inline operation which will do
a lockless read bpf peer list associated with the interface. It should
be noted that the bpf code will pickup the bpf_interface lock before adding
or removing bpf peers. This should serialize the access to the bpf descriptor
list, removing the race.
- Expose the bpf_if structure in bpf.h so that the bpf_peers_present function
can use it. This also removes the struct bpf_if; hack that was there.
- Adjust all consumers of the raw if_bpf structure to use bpf_peers_present
Now what happens is:
(1) Packet is received by netif0
(2) Check to see if bpf descriptor list is empty
(3) Pickup the bpf interface lock
(4) Hand packet off to process
From the attach/detach side:
(1) Pickup the bpf interface lock
(2) Add/remove from bpf descriptor list
Now that we are storing the bpf interface structure with the ifnet, there is
is no need to walk the bpf interface list to locate the correct bpf interface.
We now simply look up the interface, and initialize the pointer. This has a
nice side effect of changing a bpf interface attach operation from O(N) (where
N is the number of bpf interfaces), to O(1).
[1] From now on, we can no longer check ifp->if_bpf to tell us whether or
not we have any bpf peers that might be interested in receiving packets.

+ For U320 devices, check against both Settings *and* DV flags before
deciding whether we need to skip actual SPI settings for a device.
+ Go back to creating a 'physical disk' side of a raid/passthru bus that
is limited to the number of maximum physical disks. Actually, this isn't
probably *quite* right yet for one RAID volume, and if we ever end up
with finding a device that supports more than one RAID volume (not likely),
it probably won't quite be right either.
The problem here is that the creating of this 'physical' passthru sim is
just a cheap way to leverage off the CAM midlayer to do our negotiation
for us on the subentities that make up a RAID volume. It almost causes
more trouble than it is worth because we have to remember which side
we're talking to in terms of forming commands and which target ids are
real and so on. Bleah.
+ Skip trying to actually do SPI settings for the RAID volumes on the
real side of the raid/passthru bus pair- this just confuses the issue.
The underlying real physical devices will have the negotiation performed
and the Raid volume will inherit the resultant settings. At the sime time,
non-RAID devices can be on the same real bus, so *do* perform negotiations
with them.
+ At the end of doing all of the settings twiddling, *ahem*, remember to
go update the settings on the card itself (dunno how this got nuked).
At this point, negotiations *seem* to be being done (again) correctly for
both RAID volumes and their subentities. And they seem to be *mostly*
now right for other non-RAID entities on the same bus (I ended up with
3 out of 8 other disks still at narror/async- haven't the slightest
idea why yes).
Finally, negotiations on a normal bus seem to work (again).
There's still more work coming into this area, but we're in the
final stretch.
the passed target id is one of the RAID VolumeID. This result

#2 ensures that we don't get into an endless interrupt storm if busdma fails

This used to make syscons switch to vty0 when we entered DDB but this

with a flag argument saying "Debugger!"
other timeouts could not happen while suspending, including timeouts
for things like msleep. This caused the system to hang on suspend
when the cbb was enabled, since its suspend path powered down the
socket which used a timeout to wait for it to be done.
APM now creates a thread when it is enabled, and deletes the thread
when it is disabled. This thread takes the place of the timeout by
doing its polling every ~.9s. When the thread is disabled, it will
wakeup early, otherwise it times out and polls the varius things the
old timeout polled (APM events, suspend delays, etc).
This makes my Sony VAIO 505TS suspend/resume correctly when APM is
enabled (ACPI is black listed on my 505TS).
This will likely fix other problems with the suspend path where
drivers would sleep with msleep and/or do other timeouts. Maybe
there's some special case code that would use DELAY while suspending
and msleep otherwise that can be revisited and removed.

EHCI spec for linking in new qTDs into an asynchronous QH. This
requires that there is a qTD marked as not active and not halted
at the start of the QH's list, and the hardware will know to re-fetch
the qTD on each pass rather than just looking at the overlay qTD:
"The host controller must be able to advance the queue from the
Fetch QH state in order to avoid all hardware/software race
conditions. This simple mechanism allows software to simply link
qTDs to the queue head and activate them, then the host controller
will always find them if/when they are reachable."
This is achieved by keeping an "inactivesqtd" entry on the QH list,
and re-using it each time as the start of the next transfer, and
allocating a new qTD to become the next inactivesqtd. Then a new
transfer can be activated by just setting its "active" flag, which
avoids all the previous messing with overlay qTD state in
ehci_set_qh_qtd().
before starting exploring (4 seconds), and extend the wait period
if new USB buses are attached while waiting.
This works around a problem seen when there is more than one EHCI
controller in the system and you kldload usb.ko after the system
has booted. The problem is that usb.ko contains 3 separate PCI
drivers which get initialised one by one (uhci, ohci, ehci), and
when each driver is initialised, all PCI buses are re-probed after
just the addition of that driver. This means that there can be a
significant delay between the attaching of a companion controller
and the subsequent EHCI attach, so it is possible for the companion
controller's USB 1.x bus to be scanned before the EHCI driver gets
a chance to check if there is really a USB 2.x device connected.

lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP
network cards as lnc(4) did and additionally a couple of PNP ones.
Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S
and is untested due to lack of such hardware, but given that's it's
based on the respective lnc(4) and not too different from the ISA
front-end it should be highly likely to work.
- Remove the descriptions of le(4), which where converted from lnc(4),
from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common
one in sys/conf/NOTES.
still should return BUS_PROBE_LOW_PRIORITY instead of BUS_PROBE_DEFAULT
in order to give pcn(4) a chance to attach in case it probes after le(4).
- Rearrange the code related to RX interrupt handling so that ownership of
RX descriptors is immediately returned to the NIC after we have copied
the data of the hardware, allowing the NIC to already reuse the descriptor
while we are processing the data in ifp->if_input(). This results in a
small but measurable increase in RX throughput.
As a side-effect, this moves the workaround for the LANCE revision C bug
to am7900.c (still off by default as I doubt we will actually encounter
such an old chip in a machine running FreeBSD) and the workaround for the
bug in the VMware PCnet-PCI emulation to am79000.c, which is now also
only compiled on i386 (resulting in a small increase in RX throughput on
the other platforms).
- Change the RX interrupt handlers so that the descriptor error bits are
only check once in case there was no error instead of twice (inspired
by the NetBSD pcn(4), which additionally predicts the error branch as
false).
- Fix the debugging output of the RX and TX interrupt handlers; while
looping through the descriptors print info about the currently processed
one instead of always the previously last used one; remove pointless
printing of info about the RX descriptor bits after their values were
reset.
- Create the DMA tags used to allocate the memory for the init block,
descriptors and packet buffers with the alignment the respective NIC
actually requires rather than using PAGE_SIZE unconditionally. This might
as well fix the alignment of the memory as it seems we do not inherit
the alignment constraint from the parent DMA tag.
- For the PCI variants double the number of RX descriptors and buffers
from 8 to 16 as this minimizes the number of RX overflows im seeing with
one NIC-mainboard combination. Nevertheless move reporting of overflows
under debugging as they seem unavoidable with some crappy hardware.
- Set the software style of the PCI variants to ILACC rather than PCnet-PCI
as the former is was am79000.c actually implements. Should not make a
difference for this driver though.

- MPSAFE. No more recursive lock required.
- bus_dma(9) conversion. I think it should work on all architectures.
- optimized Rx handler for each normal and jumbo frames. Previously
sk(4) used jumbo frame management code to handle normal sized
frames. As the handler needs an additional lock to protect jumbo
frame management structure from races, it used two lock operations
for each received packet. Now sk(4) uses single lock operation for
normal frame.(Jumbo frame still needs two lock operations as before.)
The hardware supports DMA scatter operations for Rx descriptors such
that it's possible to take advantagee of m_cljget(9) for jumbo frames.
However, due to a unknown reasons it resulted in poor performance on
sparc64. So I dropped m_cljget(9) approach. This should be revisited
since it would reduce one lock operation for jumbo frame handling.
- Tx TCP/Rx IP checksum offload support. According to the data sheet
of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload.
But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was
disabled at the moment. It seems that newer Yukon chips can support
Tx UDP checksum offload too. But I need more documentation first.
- Added more wait time in reading VPD data. It seems that ASUS LOM
takes a very long time to respond VPD read signal.
- Added an additional lock for MII register access callbacks.
- Added more strict received packet validation routine. Previously it
passed corrupted packets to upper layers under certain conditions.
- A new function sk_yukon_tick() to handle auto-negotiation properly.
- Interrupt handler now checks shared interrupt source and protects
the interrupt handler from NULL pointer dereference which was caused
by odd status word value. The status word can returns 0xffffffff if
cable is unplugged while Rx/Tx/auto-negotiation is in progress.
- suspend/resume support(not tested).
- Added Rx/Tx FIFO flush routine for Yukon
- Activate Tx descriptor poll timer in order to protect possible loss
of SK_TXBMU_TX_START command. Previously the driver continuously issued
SK_TXBMU_TX_START when it notices pending Tx descriptors not processed
yet in interrupt handler. That approach would add additional PCI
write access overhead under high Tx load situations and it might fail
if the first SK_TXBMU_TX_START was lost and no interrupt is generated

This totally violates the PCI spec, but happens rarely enough that a

Problem reported by many, but sam@ gave me this workaround after

some systems were designed so that AML writes to various resources shared
with OS drivers, including the RTC, PIC, PCI, etc. These writes could
collide with writes by the OS and should never be performed. For now, we
print a message if such an access occurs, but do not block it. To block
the access, the tunable "debug.acpi.block_bad_io" can be set to 1. In the
future, we will flip the switch and this will become the default.
Information about this problem was found in Microsoft KB 283649. They
block IO accesses if the BIOS indicates via _OSI that it is Windows 2001
or higher. They always block accesses to the PIC, cascaded PIC, and ELCRs,
no matter how old the BIOS.

A) Fibre Channel Target Mode support mostly works

this probably works just about as well as isp(4)

B) The startup sequence has been changed so that
after all attaches are done, a set of enable functions

whatever needs to be done *prior* to a port being
enabled and the enables do what need to be done for
enabling stuff for a port after it's been enabled.
This means that we also have events handled by their
proper handlers as we start up.
C) Conditional code that means that this driver goes
back all the way to RELENG_4 in terms of support.
D) Quite a lot of little nitty bug fixes- some discovered

- Only update the rx ring consumer pointer after running through the rx loop,
not with each iteration through the loop.
- If possible, use a fast interupt handler instead of an ithread handler. Use
the interrupt handler to check and squelch the interrupt, then schedule a
taskqueue to do the actual work. This has three benefits:
- Eliminates the 'interrupt aliasing' problem found in many chipsets by
allowing the driver to mask the interrupt in the NIC instead of the
OS masking the interrupt in the APIC.
- Allows the driver to control the amount of work done in the interrupt
handler. This results in what I call 'adaptive polling', where you get
the latency benefits of a quick response to interrupts with the
interrupt mitigation and work partitioning of polling. Polling is still
an option in the driver, but I consider it orthogonal to this work.
- Don't hold the driver lock in the RX handler. The handler and all data
associated is effectively serialized already. This eliminates the cost of
dropping and reaquiring the lock for every receieved packet. The result
is much lower contention for the driver lock, resulting in lower CPU usage
and lower latency for interactive workloads.
The amount of work done in the taskqueue is controlled by the sysctl
dev.em.N.rx_processing_limit
and tunable
hw.em.rx_process_limit
Setting these to -1 effectively removes the limit.
The fast interrupt and taskqueue can be disabled by defining NO_EM_FASTINTR.
This work has been shown to increase fast-forwarding from ~570 kpps to
~750 kpps (note that the same NIC hardware seems unable to transmit more than
800 kpps, so this increase appears to be limited almost solely by the
hardware). Gains have been shown in other workloads, ranging from better
performance to elimination of over-saturation livelocks.

- Decrease TI_MAXTXSEGS to 32 from 128. It seems that most mbuf chain
length is less than 32 and it would be re-packed with m_defrag(9) if
its chain length is larger than TI_MAXTXSEGS. This would protect ti(4)
against possible kernel stack overflow when txsegs[] is put on stack.
Alternatively, we can embed the txsegs[] into softc. However, that
would waste memory and make Tx/Rx speration hard when we want to
sperate Tx/Rx handlers to optimize locking.
- Fix dma map tracking used in Tx path. Previously it used the dma map
of the last mbuf chain in ti_txeof() which was incorrect as ti(4)
used dma map of the first mbuf chain when it loads a mbuf chain with
bus_dmamap_load_mbuf(9). Correct the bug by introducing queues that
keep track of active/inactive dma maps/mbuf chain.
- Use ti_txcnt to check whether driver need to set watchdog timer instead
of blidnly clearing the timer in ti_txeof().
- Remove the 3rd arg. of ti_encap(). Since ti(4) now caches the last
descriptor index(ti_tx_saved_prodidx) used in Tx there is no need to
pass it as a fuction arg.
- Change data type of producer/consumer index to int from u_int16_t in
order to remove implicit type conversions in Tx/Rx handlers.
- Check interface queue before getting a mbuf chain to reduce locking
overhead.
- Check number of available Tx descriptores to be 16 or higher in
ti_start(). This wouldn't protect Tx descriptor shortage but it would
reduce number of bus_dmamap_unload(9) calls in ti_encap() when we are
about to running out of Tx descriptors.
- Command NIC to send packets ony when the driver really has packets
enqueued. Previously it always set TI_MB_SENDPROD_IDX which would

heavily augmented by LSI and Yahoo.
2. Implement full 64-bit DMA support. Systems with more than 4GB of RAM
can now operate without the cost of bounce buffers. Cards that cannot do
64-bit DMA will automatically revert to using bounce buffers. This option
can be forced off by setting the 'hw.amr.force_sg32" tunable in the loader.
It should only be turned off for debugging purposes. This work was sponsored

3. Streamline the command delivery and interrupt handler paths after

intended design, making it both more robust and much faster. Certain
i/o failures under heavy load should be fixed with this.
4. Optimize the locking. In the interrupt handler, the card can be checked
for completed commands without any locks held, due to the handler being
implicitely serialized and there being no need to look at any shared data.

them on the fly when descriptors need to be filled. This isn't ideal right
now because a map is allocated for every descriptor slot in the tx, rx, mini,
and jumbo rings (which is a lot!) in order to simplify the bookkeeping, even
though the driver might support filling only a subset of those slots.
Luckily, maps are typically NULL on i386 and amd64, so the cost isn't
very high. It could be an issue with sparc64, but the driver isn't endian
clean either, and that is a much bigger problem to solve first.
Note that jumbo frame support is under-tested, and I'm not even sure if
it till really works correctly given the evil VM magic that is does.
The changes here attempt to preserve the existing semanitcs.

appeared to rely on all kinds of non-guaranteed behaviours: the
transfer abort code assumed that TDs with no interrupt timeout
configured would end up on the done queue within 20ms, the done
queue processing assumed that all TDs from a transfer would appear
at the same time, and there were access-after-free bugs triggered
on failed transfers.
Attempt to fix these problems by the following changes:
- Use a maximum (6-frame) interrupt delay instead of no interrupt
delay to ensure that the 20ms wait in ohci_abort_xfer() is enough
for the TDs to have been taken off the hardware done queue.
- Defer cancellation of timeouts and freeing of TDs until we either
hit an error or reach the final TD.
- Remove TDs from the done queue before freeing them so that it
is safe to continue traversing the done queue.
This appears to fix a hang that was reproducable with revision 1.67
or 1.68 of ulpt.c (earlier revisions had a different transfer
pattern). With certain HP printers, the command "true > /dev/ulpt0"
would cause ohci_add_done() to spin because the done queue had a
loop. The list corruption was caused by a 3-TD transfer where the
first TD completed but remained on the internal host controller
done queue because it had no interrupt timeout. When the transfer
timed out, the TD got freed and reused, so it caused a loop in the
done queue when it was inserted a second time from a different
transfer.

In SNDCTL_DSP_SETFRAGMENT, if you specify both read and
write channels, the existing code first acts on the
read channel, but as a side effect it updates the
arguments (maxfrags, fragsz) passed by the caller according
to acceptable values for the read channel, and then uses the
modified values to act on the write channel.
The problem with this approach is that, given a
(maxfrags, fragsz) user-specified value, the actual
values computed by the read and write channels may differ:
e.g. the read channel might want to allocate more fragments
than what the user specified because it has no side-effects
on the delay and it helps in case of slow readers,
whereas the write channel needs to use as few fragments
as possible to keep the audio latency low (very important
with telephony apps).
This patch stores the values computed by the read channel
into temproary variables so the write channel will use
the actual arguments of the ioctl.
This patch is very helpful with telephony apps such as asterisk.

The code to compute fragment sizes in the ich driver almost
invariably ends up using the full buffer available, no matter
how the user specifies fragment size and number.
With audio telephony (8khz, 16bit-stereo) and the 16k buffer
size this results in an unbearable 500ms delay.
This patch makes sure that we never use more than 4 fragments,
(i don't think we need more unless there are huge interrupt
servicing latencies), and obey to the requested fragment size,
so that latency is acceptable.
Based on this (and after much regression tests), I can conclude
that this driver works best with 2 fragments, thus solving various
long standing issues of ICH driver not capable to flush or play
short files perfectly.

It may be the case that you may hear some unwanted noise while
playing back with 24/32 bit. This is a problem in the USB system.
Explanation from Hans Petter Selasky:
---snip---
The current USB sound driver only uses one isochronous
buffer, that is restarted when it is completed. This will lead to a short
period of time, +1ms, where no sound data is sent to the external USB device.
Depending on the load of your computer, this can be as much as 50ms. So the
USB sound driver must use 2 isochronous transfers. At the beginning one will
queue both. Then these are restarted on completion. This will result in a
constant-rate data stream to the external sound device, a minimum sound
buffer equal to the size of the isochronous buffer, and possibly the sound
will reach your ears with less delay. Little delay is a result of constant
data rate. Currently only my USB driver will support that. If one tries that
with the USB driver in *BSD, then it will crash at the first moment one gets
a buffer underrun.

Intel's web site requires some minor tweaks to get it to work:
- The driver seems to have been released with full WMI tracing enabled,
and makes references to some WMI APIs, namely IoWMIRegistrationControl(),
WmiQueryTraceInformation() and WmiTraceMessage(). Only the first
one is ever called (during intialization). These have been implemented
as do-nothing stubs for now. Also added a definition for STATUS_NOT_FOUND
to ntoskrnl_var.h, which is used as a return code for one of the WMI
routines.
- The driver references KeRaiseIrqlToDpcLevel() and KeLowerIrql()
(the latter as a function, which is unusual because normally
KeLowerIrql() is a macro in the Windows DDK that calls KfLowewIrql()).
I'm not sure why these are being called since they're not really
part of WDM. Presumeably they're being used for backwards
compatibility with old versions of Windows. These have been
implemented in subr_hal.c. (Note that they're _stdcall routines
instead of _fastcall.)
- When querying the OID_802_11_BSSID_LIST OID to get a BSSID list,
you don't know ahead of time how many networks the NIC has found
during scanning, so you're allowed to pass 0 as the list length.
This should cause the driver to return an 'insufficient resources'
error and set the length to indicate how many bytes are actually
needed. However for some reason, the Intel driver does not honor
this convention: if you give it a length of 0, it returns some
other error and doesn't tell you how much space is really needed.
To get around this, if using a length of 0 yields anything besides
the expected error case, we arbitrarily assume a length of 64K.
This is similar to the hack that wpa_supplicant uses when doing
a BSSID list query.

pin ourselves to the current CPU when thunking into Windows code.
Few other cleanups, since I'm here:
- Get rid of the ndis_isr(), ndis_enable_interrupt() and
ndis_disable_interrupt() wrappers from kern_ndis.c and just invoke
the miniport's methods directly in the interrupt handling routines
in subr_ndis.c. We may as well lose the function call overhead,
since we don't need to export these things outside of ndis.ko
now anyway.
- Remove call to ndis_enable_interrupt() from ndis_init() in if_ndis.c.
We don't need to do it there anyway (the miniport init routine handles
it, if needed).
- Fix the logic in NdisWriteErrorLogEntry() a little.
- Change some NDIS_STATUS_xxx codes in subr_ntoskrnl.c into STATUS_xxx
codes.

and increase flexibility to allow various different approaches to be tried
in the future.
- Split struct ithd up into two pieces. struct intr_event holds the list
of interrupt handlers associated with interrupt sources.
struct intr_thread contains the data relative to an interrupt thread.
Currently we still provide a 1:1 relationship of events to threads
with the exception that events only have an associated thread if there
is at least one threaded interrupt handler attached to the event. This
means that on x86 we no longer have 4 bazillion interrupt threads with
no handlers. It also means that interrupt events with only INTR_FAST
handlers no longer have an associated thread either.
- Renamed struct intrhand to struct intr_handler to follow the struct
intr_foo naming convention. This did require renaming the powerpc
MD struct intr_handler to struct ppc_intr_handler.
- INTR_FAST no longer implies INTR_EXCL on all architectures except for
powerpc. This means that multiple INTR_FAST handlers can attach to the
same interrupt and that INTR_FAST and non-INTR_FAST handlers can attach
to the same interrupt. Sharing INTR_FAST handlers may not always be
desirable, but having sio(4) and uhci(4) fight over an IRQ isn't fun
either. Drivers can always still use INTR_EXCL to ask for an interrupt
exclusively. The way this sharing works is that when an interrupt
comes in, all the INTR_FAST handlers are executed first, and if any
threaded handlers exist, the interrupt thread is scheduled afterwards.
This type of layout also makes it possible to investigate using interrupt
filters ala OS X where the filter determines whether or not its companion
threaded handler should run.
- Aside from the INTR_FAST changes above, the impact on MD interrupt code
is mostly just 's/ithread/intr_event/'.
- A new MI ddb command 'show intrs' walks the list of interrupt events
dumping their state. It also has a '/v' verbose switch which dumps
info about all of the handlers attached to each event.
- We currently don't destroy an interrupt thread when the last threaded
handler is removed because it would suck for things like ppbus(8)'s
braindead behavior. The code is present, though, it is just under
#if 0 for now.
- Move the code to actually execute the threaded handlers for an interrrupt
event into a separate function so that ithread_loop() becomes more
readable. Previously this code was all in the middle of ithread_loop()
and indented halfway across the screen.
- Made struct intr_thread private to kern_intr.c and replaced td_ithd
with a thread private flag TDP_ITHREAD.
- In statclock, check curthread against idlethread directly rather than
curthread's proc against idlethread's proc. (Not really related to intr

of the PCIR_HDRTYPE register. It's the value returned from this
read access that determines whether or not we decide a device is
present at the current slot index. For some reason that I can't
adequately explain, this read fails on my machine when probing the
USB controller on my machine (which happens a multifunction device
at slot index 3 hung off the PCI-PCI bridge on the AMD8111 (bus
index 1)). The read will return 0xFF even though it should return
0x80 to indicate the presence of a multifunction device.
As near as I can tell, there's some timing issue involved with reading
the 'dead' slot indexes 0 through 2 that causes the read of the actual
device at slot 3 to fail. I tried a couple of different tricks to
correct the problem (the patch to amd64/pci/pci_cfgreg.c fixes it
for the amd64 arch), but adding this delay is the only thing that
always allows the USB controllers to be correctly probed 100% of the
time. Whatever the problem is, it's likely confined to the AMD8111
chipset. However, a simple 1us delay is fairly harmless and should
have no side effects for other hardware. I consider this to be
voodoo, but it's fairly benign voodoo and it makes my USB keyboard
and mouse work again.
Note that this is the second time that I've had to resort to a
1us delay to fix a PCI-related problem with this AMD8111/Opteron
system (the first being a fix I made a while back to the NDISulator).
It's possible the delay really belongs in the cfgreg code itself,
or that pci_cfgreg needs some custom hackery for an errata in the
8111. (I checked but couldn't find any documented errata on AMD's
site that could account for these problems.)

generic sounding CIS "PCMCIA", "FAST ETHERENT CARD" and a bogus MANFID
code (0xffff and 0x1090). However, since I'm not aware of 'generic'
cards that aren't NE-2000oids, go with that and hope for the best.
First and most importantly, I threw out the thread priority-twiddling
implementation of KeRaiseIrql()/KeLowerIrq()/KeGetCurrentIrql() in
favor of a new scheme that uses sleep mutexes. The old scheme was
really very naughty and sought to provide the same behavior as
Windows spinlocks (i.e. blocking pre-emption) but in a way that
wouldn't raise the ire of WITNESS. The new scheme represents
'DISPATCH_LEVEL' as the acquisition of a per-cpu sleep mutex. If
a thread on cpu0 acquires the 'dispatcher mutex,' it will block
any other thread on the same processor that tries to acquire it,
in effect only allowing one thread on the processor to be at
'DISPATCH_LEVEL' at any given time. It can then do the 'atomic sit
and spin' routine on the spinlock variable itself. If a thread on
cpu1 wants to acquire the same spinlock, it acquires the 'dispatcher
mutex' for cpu1 and then it too does an atomic sit and spin to try
acquiring the spinlock.
Unlike real spinlocks, this does not disable pre-emption of all
threads on the CPU, but it does put any threads involved with
the NDISulator to sleep, which is just as good for our purposes.
This means I can now play nice with WITNESS, and I can safely do
things like call malloc() when I'm at 'DISPATCH_LEVEL,' which
you're allowed to do in Windows.
Next, I completely re-wrote most of the event/timer/mutex handling
and wait code. KeWaitForSingleObject() and KeWaitForMultipleObjects()
have been re-written to use condition variables instead of msleep().
This allows us to use the Windows convention whereby thread A can
tell thread B "wake up with a boosted priority." (With msleep(), you
instead have thread B saying "when I get woken up, I'll use this
priority here," and thread A can't tell it to do otherwise.) The
new KeWaitForMultipleObjects() has been better tested and better
duplicates the semantics of its Windows counterpart.
I also overhauled the IoQueueWorkItem() API and underlying code.
Like KeInsertQueueDpc(), IoQueueWorkItem() must insure that the
same work item isn't put on the queue twice. ExQueueWorkItem(),
which in my implementation is built on top of IoQueueWorkItem(),
was also modified to perform a similar test.
I renamed the doubly-linked list macros to give them the same names
as their Windows counterparts and fixed RemoveListTail() and
RemoveListHead() so they properly return the removed item.
I also corrected the list handling code in ntoskrnl_dpc_thread()
and ntoskrnl_workitem_thread(). I realized that the original logic
did not correctly handle the case where a DPC callout tries to
queue up another DPC. It works correctly now.
I implemented IoConnectInterrupt() and IoDisconnectInterrupt() and
modified NdisMRegisterInterrupt() and NdisMDisconnectInterrupt() to
use them. I also tried to duplicate the interrupt handling scheme
used in Windows. The interrupt handling is now internal to ndis.ko,
and the ndis_intr() function has been removed from if_ndis.c. (In
the USB case, interrupt handling isn't needed in if_ndis.c anyway.)
NdisMSleep() has been rewritten to use a KeWaitForSingleObject()
and a KeTimer, which is how it works in Windows. (This is mainly
to insure that the NDISulator uses the KeTimer API so I can spot
any problems with it that may arise.)
KeCancelTimer() has been changed so that it only cancels timers, and
does not attempt to cancel a DPC if the timer managed to fire and
queue one up before KeCancelTimer() was called. The Windows DDK
documentation seems to imply that KeCantelTimer() will also call
KeRemoveQueueDpc() if necessary, but it really doesn't.
The KeTimer implementation has been rewritten to use the callout API
directly instead of timeout()/untimeout(). I still cheat a little in
that I have to manage my own small callout timer wheel, but the timer
code works more smoothly now. I discovered a race condition using
timeout()/untimeout() with periodic timers where untimeout() fails
to actually cancel a timer. I don't quite understand where the race
is, using callout_init()/callout_reset()/callout_stop() directly
seems to fix it.
I also discovered and fixed a bug in winx32_wrap.S related to
translating _stdcall calls. There are a couple of routines
(i.e. the 64-bit arithmetic intrinsics in subr_ntoskrnl) that
return 64-bit quantities. On the x86 arch, 64-bit values are
returned in the %eax and %edx registers. However, it happens
that the ctxsw_utow() routine uses %edx as a scratch register,
and x86_stdcall_wrap() and x86_stdcall_call() were only preserving
%eax before branching to ctxsw_utow(). This means %edx was getting
clobbered in some cases. Curiously, the most noticeable effect of this
bug is that the driver for the TI AXC110 chipset would constantly drop
and reacquire its link for no apparent reason. Both %eax and %edx
are preserved on the stack now. The _fastcall and _regparm
wrappers already handled everything correctly.
I changed if_ndis to use IoAllocateWorkItem() and IoQueueWorkItem()
instead of the NdisScheduleWorkItem() API. This is to avoid possible
deadlocks with any drivers that use NdisScheduleWorkItem() themselves.
The unicode/ansi conversion handling code has been cleaned up. The
internal routines have been moved to subr_ntoskrnl and the
RtlXXX routines have been exported so that subr_ndis can call them.
This removes the incestuous relationship between the two modules
regarding this code and fixes the implementation so that it honors
the 'maxlen' fields correctly. (Previously it was possible for
NdisUnicodeStringToAnsiString() to possibly clobber memory it didn't
own, which was causing many mysterious crashes in the Marvell 8335
driver.)
The registry handling code (NdisOpen/Close/ReadConfiguration()) has
been fixed to allocate memory for all the parameters it hands out to
callers and delete whem when NdisCloseConfiguration() is called.
(Previously, it would secretly use a single static buffer.)
I also substantially updated if_ndis so that the source can now be
built on FreeBSD 7, 6 and 5 without any changes. On FreeBSD 5, only
WEP support is enabled. On FreeBSD 6 and 7, WPA-PSK support is enabled.
The original WPA code has been updated to fit in more cleanly with
the net80211 API, and to eleminate the use of magic numbers. The
ndis_80211_setstate() routine now sets a default authmode of OPEN
and initializes the RTS threshold and fragmentation threshold.
The WPA routines were changed so that the authentication mode is
always set first, followed by the cipher. Some drivers depend on
the operations being performed in this order.
I also added passthrough ioctls that allow application code to
directly call the MiniportSetInformation()/MiniportQueryInformation()
methods via ndis_set_info() and ndis_get_info(). The ndis_linksts()
routine also caches the last 4 events signalled by the driver via
NdisMIndicateStatus(), and they can be queried by an application via
a separate ioctl. This is done to allow wpa_supplicant to directly
program the various crypto and key management options in the driver,
allowing things like WPA2 support to work.

Regarding the locking I let Ariff explain it himself:
---snip---
About the locking, that is what I'm intended to do since the beginning.
The reason I'm not putting that along since my first patchset was
because several people especially from amd46 camp reported that it cause
lots of LORs, which is weird considering that I've never encounter such
in a pretty much strict locking environment (i386). However, since our
previous discussion with Pyun YongHyeon about strict locking, I've
decided to bring it back for all the affected drivers, not just for
es137x. It turns out that the root of the problem was within dsp.c
during device open, which has been fixed since dsp.c revision 1.84.

- WEP TX fix:
The original code called software crypto, ieee80211_crypto_encap(),
which never worked since IEEE80211_KEY_SWCRYPT was never flagged due to
ieee80211_crypto_newkey() assumes that wi always supports hardware based
crypto regardless of operational mode(by virtue of IEEE80211_C_WEP).
This fix works around that issue by adding wi_key_alloc() to force
the use of s/w crypto. Also if anyone ever decides to cleanup ioctl
handling where key changes wouldn't cause a call to wi_init() every time,
we'll need wi_key_alloc() to DTRT.
In addition to that, this fix also adds code to wi_write_wep() to force
existing keys to be switched between h/w and s/w crypto such that an
operation mode change(sta <-> hostap) will flag IEEE80211_KEY_SWCRYPT
properly.
- WEP RX fix:
Clear IEEE80211_F_DROPUNENC even in hostap mode. Quote from Sam:
"This is really gross but I don't see an easy way around it.
By doing it we lose the ability to independently drop unencode
frames (and support mixed wep/!wep use). We should really be
setting the EXCLUDE_UNENCRYPTED flag written in wi_write_wep
based on IEEE80211_F_DROPUNENC but with our clearing it we can't
depend on it being set properly."

- Forget and do not check if_flags, if_capenable and if_drv_flags.
- Call all registered polling handlers unconditionally.
- Do not drop poll_mtx, when entering polling handlers.

- In netisr_poll() axe the block, where polling code asks drivers
to unregister.
- In netisr_poll() and ether_poll() do polling always, if any
handlers are present.
- In ether_poll_[de]register() remove a lot of error hiding code. Assert
that arguments are correct, instead.
- In ether_poll_[de]register() use standard return values in case of
error or success.
- Introduce poll_switch() that is a sysctl handler for kern.polling.enable.
poll_switch() goes through interface list and enabled/disables polling.
A message that kern.polling.enable is deprecated is printed.
Detailed driver changes:
- On attach driver announces IFCAP_POLLING in if_capabilities, but
not in if_capenable.
- On detach driver calls ether_poll_deregister() if polling is enabled.
- In polling handler driver obtains its lock and checks IFF_DRV_RUNNING
flag. If there is no, then unlocks and returns.
- In ioctl handler driver checks for IFCAP_POLLING flag requested to
be set or cleared. Driver first calls ether_poll_[de]register(), then
obtains driver lock and [dis/en]ables interrupts.
- In interrupt handler driver checks IFCAP_POLLING flag in if_capenable.

use IRQ 5). This should be used with great caution! Generally, if the
interrupt routing in use provides specific tunables (such as hard-wiring
the IRQ for a given $PIR or ACPI PCI link device), then those should be
used instead. One instance where this tunable might be useful is if a

with some Dell servers that booted w/o a problem[*] on 5.4, but failed
with 6.0-BETA.
On the PCI bus, when we do lazy resource allocation, we narrow the
range requested as we pass through bridges to reflect how the bridges
are programmed and what addresses they pass. However, when we're
doing an allocation on a bus that's directly connected to a host
bridge, no such translation can take place. We already had a fallback
range for memory requests, but none for ioports. As such, provide a
fallback for I/O ports so we don't allocate location 0, which will
have undesired side effects when the resources are actually used.
This fixes a problem with booting a Dell server with usb in the
kernel. However, it is an unsatisfying solution. I don't like the
hard coded value, and I think we should start narrowing the resources
returned to not be in the so-called isa alias area (where the ranage &
0x0300 must be 0 iirc). Doing such filtering will have to wait for
another day.
This may be a good 6 candidate, maybe after its had a chance to be

any channel with refcount > 0 or busy).
2) vchan_create()/destroy(), (which is *sigh* quite complicated), but

The vibra16X supports full duplex. I traced the Windows driver, and what is
does is that it programs one DMA channel 8-bit, and the other 16-bit. There
might be some kind of auto detection logic here, because it always uses 8-bit
for playback, even if I play 16-bit sound ...

have been observed with different prefixes, they all work with this

by md(4). Before this change, it was possible to by-pass these flags
by creating memory disks which used a file as a backing store and
writing to the device.
This was discussed by the security team, and although this is problematic,
it was decided that it was not critical as we never guarantee that root will
be restricted.
This change implements the following behavior changes:
-If the user specifies the readonly flag, unset write operations before
opening the file. If the FWRITE mask is unset, the device will be
created with the MD_READONLY mask set. (readonly)
-Add a check in g_md_access which checks to see if the MD_READONLY mask
is set, if so return EROFS
-Do not gracefully downgrade access modes without telling the user. Instead
make the user specify their intentions for the device (assuming the file is
read only). This seems like the more correct way to handle things.
This is a RELENG_6 candidate.

which serial device to use in that case respectively to not rely on
the OFW names of the input/output and stdin/stdout devices. Instead
check whether input and output refers to the same device and is of
type serial (uart(4) was already doing this) and for the fallback
to a serial console in case a keyboard is the selected input device
but unplugged do the same for stdin and stdout in case the input
device is nonexistent (PS/2 and USB keyboards) or has a 'keyboard'
property (RS232 keyboards). Additionally also check whether the OFW
did a fallback to a serial console in the same way in case the
output device is nonexistent. While at it save on some variables
and for sys/boot/sparc64/loader/metadata.c move the code in question
to a new function md_bootserial() so it can be kept in sync with
uart_cpu_getdev_console() more easily.
This fixes selecting a serial console and the appropriate device
when using a device path for the 'input-device' and 'output-device'
OFW environment variables instead of an alias for the serial device
to use or when using a screen alias that additionally denotes a
video mode (like e.g. 'screen:r1024x768x60') but no keyboard is
plugged in (amongst others). It also makes the code select a serial
console in case the OFW did the same due to a misconfiguration like
both 'input-device' and 'output-device' set to 'keyboard' or to a
nonexisting device (whether the OFW does a fallback to a serial
console in case of a misconfiguration or one ends up with just no
console at all highly depends on the OBP version however).

o change driver/net80211 key_alloc api to return tx+rx key indices; a
driver can leave the rx key index set to IEEE80211_KEYIX_NONE or set
it to be the same as the tx key index (the former disables use of
the key index in building the keyix->node mapping table and is the
default setup for naive drivers by null_key_alloc)
o add cs_max_keyid to crypto state to specify the max h/w key index a
driver will return; this is used to allocate the key index mapping
table and to bounds check table loookups
o while here introduce ieee80211_keyix (finally) for the type of a h/w
key index
o change crypto notifiers for rx failures to pass the rx key index up

o optionally allocate a h/w key index to node mapping table for the
station table using the max key index setting supplied by drivers
(note the scan table does not get a map)
o defer node table allocation to lateattach so the driver has a chance
to set the max key id to size the key index map
o while here also defer the aid bitmap allocation
o add new ieee80211_find_rxnode_withkey api to find a sta/node entry
on frame receive with an optional h/w key index to use in checking
mapping table; also updates the map if it does a hash lookup and the
found node has a rx key index set in the unicast key; note this work
is separated from the old ieee80211_find_rxnode call so drivers do
not need to be aware of the new mechanism
o move some node table manipulation under the node table lock to close

1. Support wide range sampling rate, as low as 1hz up to int32 max
(which is, insane) through new feeder_rate, multiple precisions
choice (32/64 bit converter). This is indeed, quite insane, but it
does give us more room and flexibility. Plenty sysctl options to
adjust resampling characteristics.
2. Support 24/32 bit pcm format conversion through new, much improved,
simplified and optimized feeder_fmt.
Changes:
1. buffer.c / dsp.c / sound.h
* Support for 24/32 AFMT.
2. feeder_rate.c
* New implementation of sampling rate conversion with 32/64 bit
precision, 1 - int32max hz (which is, ridiculous, yet very
addictive). Much improved / smarter buffer management to not
cause any missing samples at the end of conversion process
* Tunable sysctls for various aspect:
hw.snd.feeder_rate_ratemin - minimum allowable sampling rate
(default to 4000)
hw.snd.feeder_rate_ratemax - maximum allowable sampling rate
(default to 1102500)
hw.snd.feeder_rate_buffersize - conversion buffer size
(default to 8192)
hw.snd.feeder_rate_scaling - scaling / conversion method
(please refer to the source for explaination). Default to
previous implementation type.
3. feeder_fmt.c / sound.h
* New implementation, support for 24/32bit conversion, optimized,
and simplified. Few routines has been removed (8 to xlaw, 16 to
8). It just doesn't make sense.
4. channel.c
* Support for 24/32 AFMT
* Fix wrong xruns increment, causing incorrect underruns statistic
while using vchans.
5. vchan.c
* Support for 24/32 AFMT
* Proper speed / rate detection especially for fixed rate ac97.
User can override it using kernel hint:
hint.pcm.<unit>.vchanrate="xxxx".
Notes / Issues:
* Virtual Channels (vchans)
Enabling vchans can really, really help to solve overrun
issues. This is quite understandable, because it operates
entirely within its own buffering system without relying on
hardware interrupt / state. Even if you don't need vchan,
just enable single channel can help much. Few soundcards
(notably via8233x, sblive, possibly others) have their own
hardware multi channel, and this is unfortunately beyond
vchan reachability.
* The arrival of 24/32 also come with a price. Applications
that can do 24/32bit playback need to be recompiled (notably
mplayer). Use (recompiled) mplayer to experiment / test /
debug this various format using -af format=fmt. Note that
24bit seeking in mplayer is a little bit broken, sometimes
can cause silence or loud static noise. Pausing / seeking
few times can solve this problem.
You don't have to rebuild world entirely for this. Simply
copy /usr/src/sys/sys/soundcard.h to
/usr/include/sys/soundcard.h would suffice. Few drivers also
need recompilation, and this can be done via
/usr/src/sys/modules/sound/.
Support for 24bit hardware playback is beyond the scope of
this changes. That would require spessific hardware driver
changes.
* Don't expect playing 9999999999hz is a wise decision. Be
reasonable. The new feeder_rate implemention provide
flexibility, not insanity. You can easily chew up your CPU
with this kind of mind instability. Please use proper
mosquito repellent device for this obvious cracked brain
attempt. As for testing purposes, you can use (again)
mplayer to generate / play with different sampling rate. Use
something like "mplayer -af resample=192000:0:0 <files>".

ACPI_BATT_GET_INFO (for _BIF-formatted data). The helper function
acpi_battery_get_battinfo() now takes a device_t instead of a unit #
argument. If dev is NULL, this signifies all batteries.
* ioctl access:
The ACPIIO_BATT_GET_TYPE and ACPIIO_BATT_GET_BATTDESC ioctls have been
removed. Since there is now no need for a mapping between "virtual" unit
and physical unit, usermode programs can just specify the unit directly and
skip the old translation steps. In fact, acpiconf(8) was actually already
doing this and virtual unit was the same as physical unit in all cases
since there was previously only one battery type (acpi_cmbat). Additionally,
we now map the ACPIIO_BATT_GET_BIF and ACPIIO_BATT_GET_BST ioctls for all
batteries, if they provide the associated methods.

Detailed Changes
================
mpt.c mpt_cam.c mpt_raid.c mpt_pci.c:
o Add support for personality modules. Each module exports
load, and unload module scope methods as well as probe, attach,
event, reset, shutdown, and detach per-device instance
methods
mpt.c mpt.h mpt_pci.c:
o The driver now associates a callback function (via an
index) with every transaction submitted to the controller.
This allows the main interrupt handler to absolve itself
of any knowledge of individual transaction/response types
by simply calling the callback function "registered" for
the transaction. We use a callback index instead of a
callback function pointer in each requests so we can
properly handle responses (e.g. event notifications)
that are not associated with a transaction. Personality
modules dynamically register their callbacks with the
driver core to receive the callback index to use for their
handlers.
o Move the interrupt handler into mpt.c. The ISR algorithm
is bus transport and OS independent and thus had no reason
to be in mpt_pci.c.
o Simplify configuration message reply handling by copying
reply frame data for the requester and storing completion
status in the original request structure.
o Add the mpt_complete_request_chain() helper method and use
it to implement reset handlers that must abort transactions.
o Keep track of all pending requests on the new
requests_pending_list in the softc.
o Add default handlers to mpt.c to handle generic event
notifications and controller reset activities. The event
handler code is largely the same as in the original driver.
The reset handler is new and terminates any pending transactions
with a status code indicating the controller needs to be
re-initialized.
o Add some endian support to the driver. A complete audit is
still required for this driver to have any hope of operating
in a big-endian environment.
o Use inttypes.h and __inline. Come closer to being style(9)
compliant.
o Remove extraneous use of typedefs.
o Convert request state from a strict enumeration to a series
of flags. This allows us to, for example, tag transactions
that have timed-out while retaining the state that the
transaction is still in-flight on the controller.
o Add mpt_wait_req() which allows a caller to poll or sleep
for the completion of a request. Use this to simplify
and factor code out from many initialization routines.
We also use this to sleep for task management request
completions in our CAM timeout handler.
mpt.c:
o Correct a bug in the event handler where request structures were
freed even if the request reply was marked as a continuation
reply. Continuation replies indicate that the controller still owns
the request and freeing these replies prematurely corrupted
controller state.
o Implement firmware upload and download. On controllers that do
not have dedicated NVRAM (as in the Sun v20/v40z), the firmware
image is downloaded to the controller by the system BIOS. This
image occupies precious controller RAM space until the host driver
fetches the image, reducing the number of concurrent I/Os the
controller can processes. The uploaded image is used to
re-program the controller during hard reset events since the
controller cannot fetch the firmware on its own. Implementing this
feature allows much higher queue depths when RAID volumes
are configured.
o Changed configuration page accessors to allow threads to sleep
rather than busy wait for completion.
o Removed hard coded data transfer sizes from configuration page
routines so that RAID configuration page processing is possible.
mpt_reg.h:
o Move controller register definitions into a separate file.
mpt.h:
o Re-arrange includes to allow inlined functions to be
defined in mpt.h.
o Add reply, event, and reset handler definitions.
o Add softc fields for handling timeout and controller
reset recovery.
mpt_cam.c:
o Move mpt_freebsd.c to mpt_cam.c. Move all core functionality,
such as event handling, into mpt.c leaving only CAM SCSI
support here.
o Revamp completion handler to provide correct CAM status for
all currently defined SCSI MPI message result codes.
o Register event and reset handlers with the MPT core. Modify
the event handler to notify CAM of bus reset events. The
controller reset handler will abort any transactions that
have timed out. All other pending CAM transactions are
correctly aborted by the core driver's reset handler.
o Allocate a single request up front to perform task management
operations. This guarantees that we can always perform a
TMF operation even when the controller is saturated with other
operations. The single request also serves as a perfect
mechanism of guaranteeing that only a single TMF is in flight
at a time - something that is required according to the MPT
Fusion documentation.
o Add a helper function for issuing task management requests
to the controller. This is used to abort individual requests
or perform a bus reset.
o Modify the CAM XPT_BUS_RESET ccb handler to wait for and
properly handle the status of the bus reset task management
frame used to reset the bus. The previous code assumed that
the reset request would always succeed.
o Add timeout recovery support. When a timeout occurs, the
timed-out request is added to a queue to be processed by
our recovery thread and the thread is woken up. The recovery
thread processes timed-out command serially, attempting first
to abort them and then falling back to a bus reset if an
abort fails.
o Add calls to mpt_reset() to reset the controller if any
handshake command, bus reset attempt or abort attempt
fails due to a timeout.
o Export a secondary "bus" to CAM that exposes all volume drive
members as pass-thru devices, allowing CAM to perform proper
speed negotiation to hidden devices.
o Add a CAM async event handler tracking the AC_FOUND_DEVICE event.
Use this to trigger calls to set the per-volume queue depth once
the volume is fully registered with CAM. This is required to avoid
hitting firmware limits on volume queue depth. Exceeding the
limit causes the firmware to hang.
mpt_cam.h:
o Add several helper functions for interfacing to CAM and
performing timeout recovery.
mpt_pci.c:
o Disable interrupts on the controller before registering and
enabling interrupt delivery to the OS. Otherwise we risk
receiving interrupts before the driver is ready to receive
them.
o Make use of compatibility macros that allow the driver to
be compiled under 4.x and 5.x.
mpt_raid.c:
o Add a per-controller instance RAID thread to perform settings
changes and query status (minimizes CPU busy wait loops).
o Use a shutdown handler to disable "Member Write Cache Enable"
(MWCE) setting for RAID arrays set to enable MWCE During Rebuild.
o Change reply handler function signature to allow handlers to defer
the deletion of reply frames. Use this to allow the event reply
handler to queue up events that need to be acked if no resources
are available to immediately ack an event. Queued events are
processed in mpt_free_request() where resources are freed. This
avoids a panic on resource shortage.
o Parse and print out RAID controller capabilities during driver probe.
o Define, allocate, and maintain RAID data structures for volumes,
hidden member physical disks and spare disks.
o Add dynamic sysctls for per-instance setting of the log level, array
resync rate, array member cache enable, and volume queue depth.
mpt_debug.c:
o Add mpt_lprt and mpt_lprtc for printing diagnostics conditioned on
a particular log level to aid in tracking down driver issues.
o Add mpt_decode_value() which parses the bits in an integer
value based on a parsing table (mask, value, name string, tuples).
mpilib/*:
o Update mpi library header files to latest distribution from LSI.

files after they were repo-copied to sys/dev/atkbdc. The sources of
atkbdc(4) and its children were moved to the new location in preparation
for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
order to not further scatter them over the whole tree which would have
been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
reason for the repo-copies was that some of the sources were misfiled,
e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
but are shareable between different atkbdc(4) bus front-ends into
atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
atkbdc(4). PS/2 controllers and input devices are used on a couple of
Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
the board it's either the only on-board mean to connect a keyboard and
mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
without isa(4) (e.g. for EBus-only machines). This ISA-specific part
isn't separated into its own source file, yet, as it requires more work
than was feasible for 6.0 in order to do it in a clean way. Actually
philip@ is working on a rewrite of psm(4) so a more comprehensive
clean-up and separation of hardware dependent and independent parts is
expected to happen after 6.0.

UARTs used to connect keyboards and not also PS/2 keyboards and only
return their package handle in case the keyboard is the preferred one
according to the OFW but otherwise still regardless of whether the

at the 'keyboard' alias and returning the corresponding package handle
in case it refers to a SCC/UART. This is change is done in order to
give the keyboard which the OFW or the user selected in OFW on boards
that support additional types of keyboards besides the RS232 ones also
preference in FreeBSD. It will be also used to determine on Sun AXi and
Sun AXmp boards whether a PS/2 or a RS232 is to be used as these are
sort of mutual exclusive there (see upcoming commit to uart_bus_ebus.c).
Note that Tatung AXi boards have the same issue but the former code
happened to already give the PS/2 keyboard preference by not identifying
the respective UART as keyboard system device there because the PS/2
keyboard node precedes the keyboard UART one in the OFW device tree of
these boards (which isn't the case for the Sun AXi).

the driver has unholy private knowledge of its great-*cgrandchildren.
The ACPI allocation routine lacked such knowledge when it tried to do
a default allocation for all descendants, rather than just its
immeidate children, so would access grandchild's ivar in an unsafe
way. This could lead to a panic when devices were present which had
no addresses setup by the BIOS, but which were later allocated in a
lazy manner via pci_alloc_map. As such, only do the default
allocation adjustments for immediate children. The manner that
acpi_sysres_find accesses the resource list, used later in
acpi_alloc_resource, is safe and proper so no additional test is
needed there.
This fixes a panic when probing an disabled ata controller on some

use with syscons(4) on sparc64. It's based on the respective NetBSD
driver with some additional info (initialisation/hardware cursor)
obtained from the Xorg 'ati' driver and some ideas taken from
creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low-
end graphics chips in PCI-based sun4u machines and are used on-board
in e.g. Blade 100 and a couple of OEM products. Most if not all of
the Sun PGX add-on cards family (descriptions of the PGX32 are
conflicting but most say it's a Rage Pro) are also based on these
chips. Depending on the version of the OBP Mach64 cards destined for
use in i386 machines also work in sun4u machines.
The driver uses pixel mode with hardware acceleration as far as
syscons(4) currently permits on sparc64 so text mode is already
quite fast. The hardware cursor is used for the mouse pointer;
for one because this is a "restriction" induced in syscons(4) on
sparc64 by creator(4) and also because of issues with mapping
the aperture when used as a low-level early during boot. Due to
insufficiencies in the available documentation I didn't manage to
get mode switch work properly (sync problems), yet. So for now
this driver relies on the OBP having initialised a mode (as does
creator(4)). On all of the tested machines is even true when using
a serial console (and also not only when the OBP switched to a
serial console because no keyboard is present). In general however
the states the Mach64 chips are left in by the OBP vary a lot
depending on the version of the OBP. This e.g. includes the aperture
not being mapped in even when used as the console and the OBP just
barfing when asked to map it. The latter is also the reason for the
existence of this native driver in FreeBSD rather than taking an
OFW frambuffer approach.
Xorg is also happy to talk to these chips by mmap'ing them through
this driver. For some hardware configs like on the Blade 100 a fix
for the Xorg sparc64 MD bus code is however needed (added in version
6.8.2_2 of the xorg-server port).
The video driver font loading and saving methods are not implemented,
yet, as syscons(4) needs more work in that area to work viable on
sparc64.
With minor modifications machfb(4) would most likely also work on
powerpc, when #ifdef'ing the OFW and possibly implementing mode
setting probably also on the other archs. The latter is however
not very practible at the moment as it would conflict with vga(4).

- Use register macros instead of magic values in the code. [1]
- Check the return values of OF_getprop() and other stuff that actually
can fail.
- Let the unimplemented video driver methods return ENODEV rather
than 0 so other code isn't tricked into thinking a certain operation
was successfull. In case of e.g. the video driver creator_ioctl()
this caused vidcontrol(1) to return random garbage information.
Remove the TODO macros in the unimplemented video driver methods
which did a printf("%s: unimplemented\n", __func__). Under certain
circumstances these managed to invoke a printf() when a low-level
console device wasn't attached, yet, causing a Fast Data Access MMU
Miss. These macros were only really usefull for development anyway.
- Set the struct video_adapter and struct video_info va_flags and
vi_flags etc. as appropriate.
- In creator_configure() don't rely on hitting the node which is the
chosen console device first when searching the OFW tree for adapters
compatible with this driver. Instead just check whether the chosen
console device is a viable target for this driver. Targets that are
not the console (including additional cards in multi-head configs)
will be attached through creator_upa_attach(). I think this how the
code in creator_configure() was actually meant to work.
Honour the VIO_PROBE_ONLY flag and don't initialise and register the
console device twice when creator_configure() is called a second time
during sc_probe_unit().
Let creator_configure() return the number of the found adapters,
i.e. 1 in case probing succeeds, as it's expected. The return values
of video adapter configure functions however currently aren't checked
so this doesn't make a difference at the moment.
- In creator_upa_attach() don't rely on probing and attaching the
adapter which is the console first, in case there are multiple
adpaters and one of them is the console this could lead into using
the video adapter unit 0 twice.
- Make the check for DACs with inverted cursor control a bit more
precise and actually honour that information when turning the cursor
on or off. Add a helper function creator_cursor_enable() for this
in order to keep code duplication low. [1]
- Don't bother with faking a hardware cursor in case a device is the
console. Apparently this was meant to start kernel output right after
where the firmware left. In general this isn't worth the fuzz and
also had no real effect as creator_set_mode() did clear the screen
in any case, not just in case a device was not the console.
- Implement creator_fill_rect() and use it to actually blank the
display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
moving blanking the display out of creator_set_mode(). Use it also
to implement creator_set_border() so the border can be re-drawn
when switching to a VTY from X, exiting X, etc. (which leaves us
with a black border most of the time).
- Implement the video driver creator_ioctl(), moving the implementation
of the IOCTL interface from the fbN CDEV version of creator_ioctl()
into the video driver version and use the latter to implement the
former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
This gives programs like vidcontrol(1) which use the video driver
creator_ioctl() a chance of working.
Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
Xorg uses to in order to inform the OS that it's taking over the
cursor. In creator_putm() check whether the cursor is enabled and
(re-)install it if necessary, moving installing the cursor out of
creator_init() and into a helper function creator_cursor_install().
This fixes the missing mouse pointer when switching to a VTY from X,
exiting X, etc.

We can't call KeFlushQueuedDpcs() during bootstrap (cold == 1), since
the flush operation sleeps to wait for completion, and we can't sleep
here (clowns will eat us).
On an i386 SMP system, if we're loaded/probed/attached during bootstrap,
smp_rendezvous() won't run us anywhere except CPU 0 (since the other CPUs
aren't launched until later), which means we won't be able to set up
the GDTs anywhere except CPU 0. To deal with this case, ctxsw_utow()
now checks to see if the TID for the current processor has been properly
initialized and sets up the GTD for the current CPU if not.
Lastly, in if_ndis.c:ndis_shutdown(), do an ndis_stop() to insure we
really halt the NIC and stop interrupts from happening.
Note that loading a driver during bootstrap is, unfortunately, kind of
a hit or miss sort of proposition. In Windows, the expectation is that
by the time a given driver's MiniportInitialize() method is called,
the system is already in 'multiuser' state, i.e. it's up and running
enough to support all the stuff specified in the NDIS API, which includes
the underlying OS-supplied facilities it implicitly depends on, such as
having all CPUs running, having the DPC queues initialized, WorkItem
threads running, etc. But in UNIX, a lot of that stuff won't work during
bootstrap. This causes a problem since we need to call MiniportInitialize()
at least once during ndis_attach() in order to find out what kind of NIC
we have and learn its station address.
What this means is that some cards just plain won't work right if
you try to pre-load the driver along with the kernel: they'll only be
probed/attach correctly if the driver is kldloaded _after_ the system
has reached multiuser. I can't really think of a way around this that
would still preserve the ability to use an NDIS device for diskless
booting.

are used onboard in most of the newer PCI-based sun4u machines
(cosmetic change as they were also already probed as generic OHCI
without this). Detect whether their intpin register is valid and
correct it if necessary, i.e. set the respective IVAR to the right
value for allocating the IRQ resource, as some of them come up
having it set to 0 (mainly those used in Blade 100 and the first
one on AX1105 boards). This fixes attaching affected controllers.
Correcting the intpin value might be better off in the PCI code
via a quirk table but on the other hand gem(4) and hem(4) also
correct it themselves and at least for the USB controller part
the intpin register is truely hardwired to 0 and can't be changed.
This means that we would have to hook up the quirk information
in a lot of places in the PCI code (i.e. whenever the value of the
intpin register is read from or written to the pci_devinfo of the
respective device) in order to do it the right way.

- Don't leak resources in case mc146818_attach() fails.

- Add support for storing the century in MK48TXX_WDAY_CB on MK48Txx with
extended registers when the MK48TXX_NO_CENT_ADJUST flag is set (and which
is termed somewhat confusing as it actually means don't manually adjust
the century in the driver).
- Add the MI part of interfacing the watchdog functionality of MK48Txx with
extended registers with watchdog(9). This is inspired by the SunOS/Solaris
drivers for the 'eeprom' devices also having watchdog support. I actually
expected this to work out of the box on Sun Exx00 machines with 'eeprom'
devices which have a 'watchdog-enable' property. On terminal count of the
the watchdog timer however only the MK48TXX_FLAGS_WDF bit rises but the
reset signal and the interrupt respectively (depending on whether the
MK48TXX_WDOG_WDS bit of the chip and the MK48TXX_WDOG_ENABLE_WDS flag
of the driver respectively is set) goes nowhere. Apparently passing the
reset signal on to the WDR line of the CPUs has to be enabled somewhere
else but we don't have documentation for the Exx00 specific controllers.
I decided to commit this nevertheless so it can be enabled in the eeprom(4)
front-end later in e.g. 6.0-STABLE without breaking the API. Besides the
Exx00 the watchdog part of the MK48Txx should also work on E250 and E450.

found someone willing to give it a try on such a machine so far.

- Revert rev. 1.7 of esp_sbus.c, since rev. 1.34 of sbus.c the clockfreq
IVAR defaults to the per-child values.
- Merge ncr53c9x.c rev. 1.111 from NetBSD (partial):
On reset, clear state flags and the msgout queue.
In NetBSD code to notify the upper layer (i.e. CAM in FreeBSD) on reset
was also added with this revision. This is believed to be not necessary
in FreeBSD and was not merged.
This makes ncr53c9x.c to be in sync with NetBSD up to rev. 1.114.
- Conditionalize the LSI64854 support on sbus(4) only instead of sbus(4)
and esp(4) as it's also required for the 'dma', 'espdma' and 'ledma'
busses/devices as well as the 'SUNW,bpp' device (printer port) which
all hang off of sbus(4).
- Add a driver for the 'dma', 'espdma' and 'ledma' (pseudo-)busses/
devices. These busses and devices actually represent the LSI64854 DMA
engines for the ESP SCSI and LANCE Ethernet controllers found on the
SBus of Ultra 1 and SBus add-on cards. With 'espdma' and 'ledma' the
'esp' and 'le' devices hang off of the respective DMA bus instead of
directly from the SBus. The 'dma' devices are either also used in this
manner or on some add-on cards also as a companion device to an 'esp'
device which also hangs off directly from the SBus. With the latter
variant it's a bit tricky to glue the DMA engine to the core logic of
the respective 'esp' device. With rev. 1.35 of sbus.c we are however
guaranteed that such a 'dma' device is probed before the respective
'esp' device which simplifies things a lot. [1]
- In the esp(4) SBus front-end read the part-unique ID code of Fast-SCSI
capable chips the right way. This fixes erroneously detecting some
chips as FAS366 when in fact they are not. Add explicit checks for the
FAS100A, FAS216 and FAS236 variants instead treating all of these as
ESP200. That way we can correctly set the respective Fast-SCSI config
bits instead of driving them out of specs. This includes adding the
FAS100A and FAS236 variants to the NCR53C9x core code. We probably
still subsume some chip variants as ESP200 while in fact they are
another variant which however shouldn't really matter as this will
only happen when these chips are driven at 25MHz or less which implies
not being able to run Fast-SCSI. [3]
- Add a workaround to the NCR53C9x interrupt handler which ignores the
stray interrupt generated by FAS100A when doing path inquiry during
boot and which otherwiese would trigger a panic.
- Add support for the 'esp' devices hanging off of a 'dma' or 'espdma'
busses or which are companions of 'dma' devices to esp(4). In case of
the variants that hang off of a DMA device this is a bit hackish as
esp(4) then directly uses the softc of the respective parent to talk
to the DMA engine. It might make sense to add an interface for this
in order to implement this in a cleaner way however it's not yet clear
how the requirements for the LANCE Ethernet controllers are and the
hack works for now. [2]
This effectively adds support for the onboard SCSI controller in
Ultra 1 as well as most of the ESP-based SBus add-on cards to esp(4).
With this the code for supporting the Performance Technologies SBS430
SBus SCSI add-on cards is also largely in place the remaining bits
were however omitted as it's unclear from the NetBSD how to couple
the DMA engine and the core logic together for these cards.

The Ralink RT2500 driver uses this API instead of NdisMIndicateReceivePacket().
Drivers use NdisMEthIndicateReceive() when they know they support
802.3 media and expect to hand their packets only protocols that want
to deal with that particular media type. With this API, the driver does
not manage its own NDIS_PACKET/NDIS_BUFFER structures. Instead, it
lets bound protocols have a peek at the data, and then they supply
an NDIS_PACKET/NDIS_BUFFER combo to the miniport driver, into which
it copies the packet data.
Drivers use NdisMIndicateReceivePacket() to allow their packets to
be read by any protocol, not just those bound to 802.3 media devices.
To make this work, we need an internal pool of NDIS_PACKETS for
receives. Currently, we check to see if the driver exports a
MiniportTransferData() method in its characteristics structure,
and only allocate the pool for drivers that have this method.
This should allow the RT2500 driver to work correctly, though I
still have to fix ndiscvt(8) to parse its .inf file properly.
Also, change kern_ndis.c:ndis_halt_nic() to reap timers before

The core console code checks this field when a console is added and
emits a warning if it's empty. In practice the warning is harmless for
uart(4), because the cn_name is filled in as soon as the device name is
known; which is when the device is enumerated.
To avoid the warning, to avoid possible complications caused by emitting
the warning without there (possibly) being a console selected yet and to
avoid complications when the UART isn't found during bus enumeration, we
just preset the cn_name field here to the name of the driver.

- Remove the old task threads from kern_ndis.c and reimplement them in
subr_ntoskrnl.c, in order to more properly emulate the Windows DPC

KeSetTargetProcessorDpc(), KeSetImportanceDpc() and KeFlushQueuedDpcs().
(This is the biggest change.)
- Fix a bug in NdisMInitializeTimer(): the k_dpc pointer in the
nmt_timer embedded in the ndis_miniport_timer struct must be set
to point to the DPC, also embedded in the struct. Failing to do
this breaks dequeueing of DPCs submitted via timers, and in turn
breaks cancelling timers.
- Fix a bug in KeCancelTimer(): if the timer is interted in the timer
queue (i.e. the timeout callback is still pending), we have to both
untimeout() the timer _and_ call KeRemoveQueueDpc() to nuke the DPC
that might be pending. Failing to do this breaks cancellation of
periodic timers, which always appear to be inserted in the timer queue.
- Make use of the nmt_nexttimer field in ndis_miniport_timer: keep a
queue of pending timers and cancel them all in ndis_halt_nic(), prior
to calling MiniportHalt(). Also call KeFlushQueuedDpcs() to make sure
any DPCs queued by the timers have expired.
- Modify NdisMAllocateSharedMemory() and NdisMFreeSharedMemory() to keep
track of both the virtual and physical addresses of the shared memory
buffers that get handed out. The AirGo MIMO driver appears to have a bug
in it: for one of the segments is allocates, it returns the wrong
virtual address. This would confuse NdisMFreeSharedMemory() and cause
a crash. Why it doesn't crash Windows too I have no idea (from reading
the documentation for NdisMFreeSharedMemory(), it appears to be a violation
of the API).
- Implement strstr(), strchr() and MmIsAddressValid().
- Implement IoAllocateWorkItem(), IoFreeWorkItem(), IoQueueWorkItem() and

fact that access to RR0 does not need a prior write to the register
index because the index always reverts to 0 after the indexed register
has been accessed.
Typically when a RR or WR is to accessed, one programs the index (which
is a write to the control register), followed by a read or write to the
actual indexed register (a read pr write to the same control register).
When this non-atomic sequence is interrupted after having written the
index and low-level console I/O is done in that situation, the write to
program the index will actually write to the indexed register and nuke
state. This almost always yields a wedge.
By not programming the index register and instead just reading from RR0,
the worst case scenario is non-fatal. For if we don't actually read from
RR0 but some other register we get an invalid status, which may lead us
to conclude that the transit data register is empty when it's not or that
the receive data register contains data when it doesn't. Hence, we may
lose an output character or get a sporadic input character, but given
the situation this is a non-issue.

here on in, if_ndis.ko will be pre-built as a module, and can be built
into a static kernel (though it's not part of GENERIC). Drivers are
created using the new ndisgen(8) script, which uses ndiscvt(8) under
the covers, along with a few other tools. The result is a driver module
that can be kldloaded into the kernel.
A driver with foo.inf and foo.sys files will be converted into
foo_sys.ko (and foo_sys.o, for those who want/need to make static
kernels). This module contains all of the necessary info from the
.INF file and the driver binary image, converted into an ELF module.
You can kldload this module (or add it to /boot/loader.conf) to have
it loaded automatically. Any required firmware files can be bundled
into the module as well (or converted/loaded separately).
Also, add a workaround for a problem in NdisMSleep(). During system
bootstrap (cold == 1), msleep() always returns 0 without actually
sleeping. The Intel 2200BG driver uses NdisMSleep() to wait for
the NIC's firmware to come to life, and fails to load if NdisMSleep()
doesn't actually delay. As a workaround, if msleep() (and hence
ndis_thsuspend()) returns 0, use a hard DELAY() to sleep instead).
This is not really the right thing to do, but we can't really do much
else. At the very least, this makes the Intel driver happy.
There are probably other drivers that fail in this way during bootstrap.
Unfortunately, the only workaround for those is to avoid pre-loading
them and kldload them once the system is running instead.

layer, but with a twist.
The twist has to do with the fact that Microsoft supports structured
exception handling in kernel mode. On the i386 arch, exception handling
is implemented by hanging an exception registration list off the
Thread Environment Block (TEB), and the TEB is accessed via the %fs
register. The problem is, we use %fs as a pointer to the pcpu stucture,
which means any driver that tries to write through %fs:0 will overwrite
the curthread pointer and make a serious mess of things.
To get around this, Project Evil now creates a special entry in
the GDT on each processor. When we call into Windows code, a context
switch routine will fix up %fs so it points to our new descriptor,
which in turn points to a fake TEB. When the Windows code returns,
or calls out to an external routine, we swap %fs back again. Currently,
Project Evil makes use of GDT slot 7, which is all 0s by default.
I fully expect someone to jump up and say I can't do that, but I
couldn't find any code that makes use of this entry anywhere. Sadly,
this was the only method I could come up with that worked on both
UP and SMP. (Modifying the LDT works on UP, but becomes incredibly
complicated on SMP.) If necessary, the context switching stuff can
be yanked out while preserving the convention calling wrappers.
(Fortunately, it looks like Microsoft uses some special epilog/prolog
code on amd64 to implement exception handling, so the same nastiness
won't be necessary on that arch.)
The advantages are:
- Any driver that uses %fs as though it were a TEB pointer won't
clobber pcpu.
- All the __stdcall/__fastcall/__regparm stuff that's specific to
gcc goes away.
Also, while I'm here, switch NdisGetSystemUpTime() back to using

critical_enter() and critical_exit() are now solely a mechanism for
deferring kernel preemptions. They no longer have any affect on
interrupts. This means that standalone critical sections are now very
cheap as they are simply unlocked integer increments and decrements for the
common case.
Spin mutexes now use a separate KPI implemented in MD code: spinlock_enter()
and spinlock_exit(). This KPI is responsible for providing whatever MD
guarantees are needed to ensure that a thread holding a spin lock won't
be preempted by any other code that will try to lock the same lock. For
now all archs continue to block interrupts in a "spinlock section" as they
did formerly in all critical sections. Note that I've also taken this
opportunity to push a few things into MD code rather than MI. For example,
critical_fork_exit() no longer exists. Instead, MD code ensures that new
threads have the correct state when they are created. Also, we no longer
try to fixup the idlethreads for APs in MI code. Instead, each arch sets
the initial curthread and adjusts the state of the idle thread it borrows
in order to perform the initial context switch.
This change is largely a big NOP, but the cleaner separation it provides
will allow for more efficient alternative locking schemes in other parts
of the kernel (bare critical sections rather than per-CPU spin mutexes
for per-CPU data for example).

o ATA RAID can only read metadata from all the above metadata formats,
not write all of them (Promise and Highpoint V2 so far). This means
that arrays can be picked up from the BIOS, but they cannot be
created from FreeBSD. There is more to it than just the missing
write metadata support, those formats are not unique to a given
controller like Promise and Highpoint formats, instead they exist
for several types, and even worse, some controllers can have
different formats and its impossible to tell which one.
The outcome is that we cannot reliably create the metadata of those

work on SMP" saga. After several weeks and much gnashing of teeth,
I have finally tracked down all the problems, despite their best
efforts to confound and annoy me.
Problem nunmber one: the Atheros windows driver is _NOT_ a de-serialized
miniport! It used to be that NDIS drivers relied on the NDIS library
itself for all their locking and serialization needs. Transmit packet
queues were all handled internally by NDIS, and all calls to
MiniportXXX() routines were guaranteed to be appropriately serialized.
This proved to be a performance problem however, and Microsoft
introduced de-serialized miniports with the NDIS 5.x spec. Microsoft
still supports serialized miniports, but recommends that all new drivers
written for Windows XP and later be deserialized. Apparently Atheros
wasn't listening when they said this.
This means (among other things) that we have to serialize calls to
MiniportSendPackets(). We also have to serialize calls to MiniportTimer()
that are triggered via the NdisMInitializeTimer() routine. It finally
dawned on me why NdisMInitializeTimer() takes a special
NDIS_MINIPORT_TIMER structure and a pointer to the miniport block:
the timer callback must be serialized, and it's only by saving the
miniport block handle that we can get access to the serialization
lock during the timer callback.
Problem number two: haunted hardware. The thing that was _really_
driving me absolutely bonkers for the longest time is that, for some
reason I couldn't understand, my test machine would occasionally freeze
or more frustratingly, reset completely. That's reset and in *pow!*
back to the BIOS startup. No panic, no crashdump, just a reset. This
appeared to happen most often when MiniportReset() was called. (As
to why MiniportReset() was being called, see problem three below.)
I thought maybe I had created some sort of horrible deadlock
condition in the process of adding the serialization, but after three
weeks, at least 6 different locking implementations and heroic efforts
to debug the spinlock code, the machine still kept resetting. Finally,
I started single stepping through the MiniportReset() routine in
the driver using the kernel debugger, and this ultimately led me to
the source of the problem.
One of the last things the Atheros MiniportReset() routine does is
call NdisReadPciSlotInformation() several times to inspect a portion
of the device's PCI config space. It reads the same chunk of config
space repeatedly, in rapid succession. Presumeably, it's polling
the hardware for some sort of event. The reset occurs partway through
this process. I discovered that when I single-stepped through this
portion of the routine, the reset didn't occur. So I inserted a 1
microsecond delay into the read loop in NdisReadPciSlotInformation().
Suddenly, the reset was gone!!
I'm still very puzzled by the whole thing. What I suspect is happening
is that reading the PCI config space so quickly is causing a severe
PCI bus error. My test system is a Sun w2100z dual Opteron system,
and the NIC is a miniPCI card mounted in a miniPCI-to-PCI carrier card,
plugged into a 100Mhz PCI slot. It's possible that this combination of
hardware causes a bus protocol violation in this scenario which leads
to a fatal machine check. This is pure speculation though. Really all I
know for sure is that inserting the delay makes the problem go away.
(To quote Homer Simpson: "I don't know how it works, but fire makes
it good!")
Problem number three: NdisAllocatePacket() needs to make sure to
initialize the npp_validcounts field in the 'private' section of
the NDIS_PACKET structure. The reason if_ndis was calling the
MiniportReset() routine in the first place is that packet transmits
were sometimes hanging. When sending a packet, an NDIS driver will
call NdisQueryPacket() to learn how many physical buffers the packet
resides in. NdisQueryPacket() is actually a macro, which traverses
the NDIS_BUFFER list attached to the NDIS_PACKET and stashes some
of the results in the 'private' section of the NDIS_PACKET. It also
sets the npp_validcounts field to TRUE To indicate that the results are
now valid. The problem is, now that if_ndis creates a pool of transmit
packets via NdisAllocatePacketPool(), it's important that each time
a new packet is allocated via NdisAllocatePacket() that validcounts
be initialized to FALSE. If it isn't, and a previously transmitted
NDIS_PACKET is pulled out of the pool, it may contain stale data
from a previous transmission which won't get updated by NdisQueryPacket().
This would cause the driver to miscompute the number of fragments
for a given packet, and botch the transmission.
Fixing these three problems seems to make the Atheros driver happy
on SMP, which hopefully means other serialized miniports will be
happy too.
And there was much rejoicing.
Other stuff fixed along the way:
- Modified ndis_thsuspend() to take a mutex as an argument. This
allows KeWaitForSingleObject() and KeWaitForMultipleObjects() to
avoid any possible race conditions with other routines that
use the dispatcher lock.
- Fixed KeCancelTimer() so that it returns the correct value for
'pending' according to the Microsoft documentation
- Modfied NdisGetSystemUpTime() to use ticks and hz rather than
calling nanouptime(). Also added comment that this routine wraps
after 49.7 days.
- Added macros for KeAcquireSpinLock()/KeReleaseSpinLock() to hide
all the MSCALL() goop.
- For x86, KeAcquireSpinLockRaiseToDpc() needs to be a separate
function. This is because it's supposed to be _stdcall on the x86
arch, whereas KeAcquireSpinLock() is supposed to be _fastcall.
On amd64, all routines use the same calling convention so we can
just map KeAcquireSpinLockRaiseToDpc() directly to KfAcquireSpinLock()
and it will work. (The _fastcall attribute is a no-op on amd64.)
- Implement and use IoInitializeDpcRequest() and IoRequestDpc() (they're
just macros) and use them for interrupt handling. This allows us to
move the ndis_intrtask() routine from if_ndis.c to kern_ndis.c.
- Fix the MmInitializeMdl() macro so that is uses sizeof(vm_offset_t)
when computing mdl_size instead of uint32_t, so that it matches the
MmSizeOfMdl() routine.
- Change a could of M_WAITOKs to M_NOWAITs in the unicode routines in
subr_ndis.c.
- Use the dispatcher lock a little more consistently in subr_ntoskrnl.c.
- Get rid of the "wait for link event" hack in ndis_init(). Now that
I fixed NdisReadPciSlotInformation(), it seems I don't need it anymore.
This should fix the witness panic a couple of people have reported.
- Use MSCALL1() when calling the MiniportHangCheck() function in
ndis_ticktask(). I accidentally missed this one when adding the
wrapping for amd64.

at some point result in a status event being triggered (it should
be a link down event: the Microsoft driver design guide says you
should generate one when the NIC is initialized). Some drivers
generate the event during MiniportInitialize(), such that by the
time MiniportInitialize() completes, the NIC is ready to go. But
some drivers, in particular the ones for Atheros wireless NICs,
don't generate the event until after a device interrupt occurs
at some point after MiniportInitialize() has completed.
The gotcha is that you have to wait until the link status event
occurs one way or the other before you try to fiddle with any
settings (ssid, channel, etc...). For the drivers that set the
event sycnhronously this isn't a problem, but for the others
we have to pause after calling ndis_init_nic() and wait for the event
to arrive before continuing. Failing to wait can cause big trouble:
on my SMP system, calling ndis_setstate_80211() after ndis_init_nic()
completes, but _before_ the link event arrives, will lock up or
reset the system.
What we do now is check to see if a link event arrived while
ndis_init_nic() was running, and if it didn't we msleep() until
it does.
Along the way, I discovered a few other problems:
- Defered procedure calls run at PASSIVE_LEVEL, not DISPATCH_LEVEL.
ntoskrnl_run_dpc() has been fixed accordingly. (I read the documentation
wrong.)
- Similarly, the NDIS interrupt handler, which is essentially a
DPC, also doesn't need to run at DISPATCH_LEVEL. ndis_intrtask()
has been fixed accordingly.
- MiniportQueryInformation() and MiniportSetInformation() run at
DISPATCH_LEVEL, and each request must complete before another
can be submitted. ndis_get_info() and ndis_set_info() have been
fixed accordingly.
- Turned the sleep lock that guards the NDIS thread job list into
a spin lock. We never do anything with this lock held except manage
the job list (no other locks are held), so it's safe to do this,
and it's possible that ndis_sched() and ndis_unsched() can be
called from DISPATCH_LEVEL, so using a sleep lock here is
semantically incorrect. Also updated subr_witness.c to add the
lock to the order list.
Change fhc(4) to use IRQ numbers instead of RIDs for allocating the
IRQs of children. This works similar to e.g. sbus(4), i.e. add the
IRQ resources as fully specified to the resource lists of the children,
allocate them like normal. When establishing the interrupt search the
interrupt maps of the children for a matching INO to determine which
map we need to write the fully specified interrupt number to and to
enable the mapping (before the RID was used to indicate which interrupt
map to use).

for a given device in some circumstances, so move the PDO creation
to the attach routine so we don't end up creating two PDOs.
Also, when we skip the call to ndis_convert_res() in if_ndis.c:ndis_attach(),
initialize sc->ndis_block->nmb_rlist to NULL. We don't explicitly zero
the miniport block, so this will make sure ndis_unload_driver() does
the right thing.
when we create a PDO, the driver_object associated with it is that
of the parent driver, not the driver we're trying to attach. For
example, if we attach a PCI device, the PDO we pass to the NdisAddDevice()
function should contain a pointer to fake_pci_driver, not to the NDIS
driver itself. For PCI or PCMCIA devices this doesn't matter because
the child never needs to talk to the parent bus driver, but for USB,
the child needs to be able to send IRPs to the parent USB bus driver, and
for that to work the parent USB bus driver has to be hung off the PDO.
This involves modifying windrv_lookup() so that we can search for
bus drivers by name, if necessary. Our fake bus drivers attach themselves
as "PCI Bus," "PCCARD Bus" and "USB Bus," so we can search for them
using those names.
The individual attachment stubs now create and attach PDOs to the
parent bus drivers instead of hanging them off the NDIS driver's
object, and in if_ndis.c, we now search for the correct driver
object depending on the bus type, and use that to find the correct PDO.
With this fix, I can get my sample USB ethernet driver to deliver
an IRP to my fake parent USB bus driver's dispatch routines.

deserves a big thanks for submitting initial patches to make it
work. I have mangled his contributions appropriately.
The main gotcha with Windows/x86-64 is that Microsoft uses a different
calling convention than everyone else. The standard ABI requires using
6 registers for argument passing, with other arguments on the stack.
Microsoft uses only 4 registers, and requires the caller to leave room
on the stack for the register arguments incase the callee needs to
spill them. Unlike x86, where Microsoft uses a mix of _cdecl, _stdcall
and _fastcall, all routines on Windows/x86-64 uses the same convention.
This unfortunately means that all the functions we export to the
driver require an intermediate translation wrapper. Similarly, we have
to wrap all calls back into the driver binary itself.
The original patches provided macros to wrap every single routine at
compile time, providing a secondary jump table with a customized
wrapper for each exported routine. I decided to use a different approach:
the call wrapper for each function is created from a template at
runtime, and the routine to jump to is patched into the wrapper as
it is created. The subr_pe module has been modified to patch in the
wrapped function instead of the original. (On x86, the wrapping
routine is a no-op.)
There are some minor API differences that had to be accounted for:
- KeAcquireSpinLock() is a real function on amd64, not a macro wrapper
around KfAcquireSpinLock()
- NdisFreeBuffer() is actually IoFreeMdl(). I had to change the whole
NDIS_BUFFER API a bit to accomodate this.
Bugs fixed along the way:
- IoAllocateMdl() always returned NULL
- kern_windrv.c:windrv_unload() wasn't releasing private driver object
extensions correctly (found thanks to memguard)

Windows DRIVER_OBJECT and DEVICE_OBJECT mechanism so that we can
simulate driver stacking.
In Windows, each loaded driver image is attached to a DRIVER_OBJECT
structure. Windows uses the registry to match up a given vendor/device
ID combination with a corresponding DRIVER_OBJECT. When a driver image
is first loaded, its DriverEntry() routine is invoked, which sets up
the AddDevice() function pointer in the DRIVER_OBJECT and creates
a dispatch table (based on IRP major codes). When a Windows bus driver
detects a new device, it creates a Physical Device Object (PDO) for
it. This is a DEVICE_OBJECT structure, with semantics analagous to
that of a device_t in FreeBSD. The Windows PNP manager will invoke
the driver's AddDevice() function and pass it pointers to the DRIVER_OBJECT
and the PDO.
The AddDevice() function then creates a new DRIVER_OBJECT structure of
its own. This is known as the Functional Device Object (FDO) and
corresponds roughly to a private softc instance. The driver uses
IoAttachDeviceToDeviceStack() to add this device object to the
driver stack for this PDO. Subsequent drivers (called filter drivers
in Windows-speak) can be loaded which add themselves to the stack.
When someone issues an IRP to a device, it travel along the stack
passing through several possible filter drivers until it reaches
the functional driver (which actually knows how to talk to the hardware)
at which point it will be completed. This is how Windows achieves
driver layering.
Project Evil now simulates most of this. if_ndis now has a modevent
handler which will use MOD_LOAD and MOD_UNLOAD events to drive the
creation and destruction of DRIVER_OBJECTs. (The load event also
does the relocation/dynalinking of the image.) We don't have a registry,
so the DRIVER_OBJECTS are stored in a linked list for now. Eventually,
the list entry will contain the vendor/device ID list extracted from
the .INF file. When ndis_probe() is called and detectes a supported
device, it will create a PDO for the device instance and attach it
to the DRIVER_OBJECT just as in Windows. ndis_attach() will then call
our NdisAddDevice() handler to create the FDO. The NDIS miniport block
is now a device extension hung off the FDO, just as it is in Windows.
The miniport characteristics table is now an extension hung off the
DRIVER_OBJECT as well (the characteristics are the same for all devices
handled by a given driver, so they don't need to be per-instance.)
We also do an IoAttachDeviceToDeviceStack() to put the FDO on the
stack for the PDO. There are a couple of fake bus drivers created
for the PCI and pccard buses. Eventually, there will be one for USB,
which will actually accept USB IRP.s
Things should still work just as before, only now we do things in
the proper order and maintain the correct framework to support passing
IRPs between drivers.

- corrected the comments about IRQL handling in subr_hal.c to more
accurately reflect reality
- update ndiscvt to make the drv_data symbol in ndis_driver_data.h a

- Obtain the softc pointer from the miniport block by referencing
the PDO rather than a private pointer of our own (nmb_ifp is no
longer used)
- implement IoAttachDeviceToDeviceStack(), IoDetachDevice(),
IoGetAttachedDevice(), IoAllocateDriverObjectExtension(),
IoGetDriverObjectExtension(), IoCreateDevice(), IoDeleteDevice(),
IoAllocateIrp(), IoReuseIrp(), IoMakeAssociatedIrp(), IoFreeIrp(),

- fix a few mistakes in the driver_object and device_object definitions
- add a new module, kern_windrv.c, to handle the driver registration

kern_ndis.c).
- made ndis_block and ndis_chars in the ndis_softc stucture pointers
and modified all references to it
- fixed NdisMRegisterMiniport() and NdisInitializeWrapper() so they
work correctly with the new driver_object mechanism
- changed ndis_attach() to call NdisAddDevice() instead of ndis_load_driver()

Discussed with: bde
The cause of "Duplicate mbuf free panic" is in the programming
error of hme_load_txmbuf(). The code path of the panic is the
following.
1. Due to unknown reason DMA engine was freezed. So TX descritors
of HME become full and the last failed attempt to transmit a
packet had set its associated mbuf address to hme_txdesc
structure. Also the failed packet is requeued into interface
queue structure in order to retrasmit it when there are more
available TX descritors.
2. Since DMA engine was freezed, if_timer starts to decrement its
counter. When if_timer expires it tries to reset HME. During
the reset phase, hme_meminit() is called and it frees all
associated mbuf with descriptors. The last failed mbuf is also
freed here.
3. After HME reset completed, HME starts to retransmit packets
by dequeing the first packet in interface queue.(Note! the
packet was already freed in hme_meminit()!)
4. When a TX completion interrupt is posted by the HME, driver
tries to free the successfylly transmitted mbuf. Since the
mbuf was freed in step2, now we get "Duplicate mbuf free panic".
However, the real cause is in DMA engine freeze. Since no fatal
errors reported via interrupts, there might be other cause of
the freeze. I tried hard to understand the cause of DMA engine
freeze but couldn't find any clues. It seems that the freeze
happens under very high network loads(e.g. 7.5-8.0 MB/s TX speed).
Though this fix is not enough to eliminate DMA engine freeze it's
better than panic.

engineering the pending interrupt sources from the current
state of the controller. For channel A we can always read the
interrupt pending register (RR3). For channel B we can read
the interrupt vector register (RR2) because it contains the
modified vector and thus includes the interrupt source.
Since we currently need puc(4) for the Z8530, we know that
the interrupt handler for both channels will be called and
thus that RR3 will always be read at least once, even if ch A
has no pending interrupt.
NOTE: The modified interrupt vector has no value that represent
a lack of pending interrupt for channel B. That is, the
value read when no interrupts are pending is the same as the
value for the special receive condition. Fortunately, we don't
actually have to depend on that interrupt source. This does
mean that we need to properly handle the overflow condition,
when we read received character from the chip.

This applies to other capability bits, too. The user
obviously has a reason for clearing a capability bit,
e.g., if his particular NIC is buggy and hangs if a
certain hardware capability is turned on even for a
fraction of a second.
The flag adapter->em_insert_vlan_header still is set or

NetBSD went this route a while ago. FreeBSD originally tried this to

better off not worrying about the function number, and instead worry
about the function type for the function. This has worked well in
