This is triggered only if BIOS configures ACPI_BITREG_BUS_MASTER_RLD

Rationale:
1. we do not support C3 on PIIX4E
2. bus master activity need not break out of C2 state
3. because of CPU_QUIRK_NO_BM_CTRL quirk we may reset bus master

The TTY buffers used the standard <sys/queue.h> lists. Unfortunately

I switched to custom linked list macros. The macros will also keep track
of the amount of items in the list. Because it doesn't use a sentinel,
we can just initialize the queues with zero.
In its simplest form (the output queue), we will only keep two
references to blocks in the queue, namely the head of the list and the
last block in use. All free blocks are stored behind the last block in
use.

Inside the kernel, the minor() function was responsible for obtaining
the device minor number of a character device. Because we made device
numbers dynamically allocated and independent of the unit number passed
to make_dev() a long time ago, it was actually a misnomer. If you really
want to obtain the device number, you should use dev2udev().
We already converted all the drivers to use dev2unit() to obtain the
device unit number, which is still used by a lot of drivers. I've
noticed not a single driver passes NULL to dev2unit(). Even if they
would, its behaviour would make little sense. This is why I've removed
the NULL check.
Ths commit removes minor(), minor2unit() and unit2minor() from the
kernel. Because there was a naming collision with uminor(), we can
rename umajor() and uminor() back to major() and minor(). This means
that the makedev(3) manual page also applies to kernel space code now.
I suspect umajor() and uminor() isn't used that often in external code,
but to make it easier for other parties to port their code, I've

a group, give each ppc(4) device a mutex which it shares with all the
child devices including ppbus(4), lpt(4), plip(4), etc. This mutex
is then used for all the locking.
- Rework the interrupt handling stuff yet again. Now ppbus drivers setup
their interrupt handler during attach and tear it down during detach
like most other drivers. ppbus(4) only invokes the interrupt handler
of the device that currently owns the bus (if any) when an interrupt
occurs, however. Also, interrupt handlers in general now accept their
softc pointers as their argument rather than the device_t. Another
feature of the ppbus interrupt handlers is that they are called with
the parent ppc device's lock already held. This minimizes the number
of lock operations during an interrupt.

- Make white foreground and background work in teken_demo.
Cons25 doesn't seem to use a straight 1:1 mapping to the ANSI colors,
but uses the same color numbers as at least used by syscons on i386. I
suspect if you change the definitions on a different architecture,
things may break? Not sure.
Add a small array to convert syscons-style color codes to ANSI
equivalents, which are used by libteken internally. I didn't notice this
bug, because I only tested my code with black, white and green, all of
them shared the same numbers.
It turns out I forgot to implement two escape sequences that allows the
user to change the default foreground and background colors. I thought
they were implemented by syscons itself, but vidcontrol just generates
some escape sequences, which get interpreted by the terminal emulator.

The teken library already supports UTF-8 handling and xterm emulation,
but we have reasons to disable this right now. Because we should make it
easy and interesting for people to experiment with these features, allow
them to be set in kernel configuration files.
Before this commit we had a flag called `TEKEN_CONS25' to enable
cons25-style emulation. I'm calling it the opposite now, `TEKEN_XTERM',
because we want to enable it in kernel configuration files explicitly.

for jumbo frame.
o Nuke unneeded jlist lock which was used to protect jumbo buffer
management in local allocator.
o Added a new tunable hw.mskc.jumbo_disable to disable jumbo
frame support for the driver. The tunable could be set for
systems that do not need to use jumbo frames and it would
save (9K * number of Rx descriptors) bytes kernel memory.
o Jumbo buffer allocation failure is no longer critical error
for the operation of msk(4). If msk(4) encounter the allocation
failure it just disables jumbo frame support and continues to
work without your intervention.
Using local allocator had several drawbacks such as requirement of
large amount of continuous kernel memory and fixed (small) number
of available buffers. The need for large continuous memory resulted
in failure of loading driver with kldload on running systems.
Also small number of buffer used in local allocator showed poor
performance for some applications.

The cursor is only inside the scrolling region when we are in origin
mode. In that case, it should use originreg instead of scrollreg. It is
completely valid to place the cursor outside the scrolling region.
Some time ago I started working on a library called libteken, which is
terminal emulator. It does not buffer any screen contents, but only
keeps terminal state, such as cursor position, attributes, etc. It
should implement all escape sequences that are implemented by the
cons25 terminal emulator, but also a fair amount of sequences that are
present in VT100 and xterm.
A lot of random notes, which could be of interest to users/developers:
- Even though I'm leaving the terminal type set to `cons25', users can
do experiments with placing `xterm-color' in /etc/ttys. Because we
only implement a subset of features of xterm, this may cause
artifacts. We should consider extending libteken, because in my
opinion xterm is the way to go. Some missing features:
- Keypad application mode (DECKPAM)
- Character sets (SCS)
- libteken is filled with a fair amount of assertions, but unfortunately
we cannot go into the debugger anymore if we fail them. I've done
development of this library almost entirely in userspace. In
sys/dev/syscons/teken there are two applications that can be helpful
when debugging the code:
- teken_demo: a terminal emulator that can be started from a regular
xterm that emulates a terminal using libteken. This application can
be very useful to debug any rendering issues.
- teken_stress: a stress testing application that emulates random
terminal output. libteken has literally survived multiple terabytes
of random input.
- libteken also includes support for UTF-8, but unfortunately our input
layer and font renderer don't support this. If users want to
experiment with UTF-8 support, they can enable `TEKEN_UTF8' in
teken.h. If you recompile your kernel or the teken_demo application,
you can hold some nice experiments.
- I've left PC98 the way it is right now. The PC98 platform has a custom
syscons renderer, which supports some form of localised input. Maybe
we should port PC98 to libteken by the time syscons supports UTF-8?
- I've removed the `dumb' terminal emulator. It has been broken for
years. It hasn't survived the `struct proc' -> `struct thread'
conversion.
- To prevent confusion among people that want to hack on libteken:
unlike syscons, the state machines that parse the escape sequences are
machine generated. This means that if you want to add new escape
sequences, you have to add an entry to the `sequences' file. This will
cause new entries to be added to `teken_state.h'.
- Any rendering artifacts that didn't occur prior to this commit are by
accident. They should be reported to me, so I can fix them.

Instead of a single calibration interval we now have short and long
intervals; the long interval roughly corresponds to the previous
single interval. The short interval is used to speedup collection
of samples and happens much quicker. We make calls using the short
interval until we're told the calibration work is complete at which
point we fallback to the long interval. In addition there is a
much longer reset interval used to flush all calibration state and
cause everthing to start anew.
With these changes you can also disable calibration entirely by
setting the long interval to zero.

o WOL support requires help of a firmware so add check whether
hardware is capable of handling magic frames by reading EEPROM.
o Enable accepting WOL frames only when hardware is about to
suspend or shutdown. Previously fxp(4) used to allow receipt of
magic frame under normal operation mode which could cause
hardware hang if magic frame is received by hardware. Datasheet
clearly states driver should not allow WOL frames under normal
operation mode.
o Disable WOL frame reception in device attach so have fxp(4)

packets when the hardware is not in fully initialized state.
o Don't reset all hardware configuration data in fxp_stop()

reset WOL configuration to default state which in turn cause
hardware hang on receipt of magic frames. To fix the issue,
preserve hardware configuration data by issuing a selective

o Configure controller to use dynamic TBD as TSO requires that

o Add a dummy TBD to tx_cb_u as TSO can access one more TBD in TSO
operation.
o Increase a DMA segment size to 4096 to hold a full IP segment
with link layer header.
o Unlike other TSO capable controllers, 82550/82551 does not
modify the first IP packet in TSO operation so driver should
create an IP packet with proper header. Subsequent IP packets
are generated from the header information in the first IP packet
header. Likewise pseudo checksum also should be computed by
driver for the first packet.
o TSO requires one more TBD to hold total TCP payload. To make
code simple for TSO/non-TSO case, increase the index of the
first available TBD array.
o Remove KASSERT that checks the size of a DMA segment should be
less than or equal to MCLBYTES as it's no longer valid in TSO.
o Tx threshold and number of TBDs field is used to store MSS in
TSO. So don't set the Tx threshold in TSO case.
82559 or later controllers added simple checksum calculation logic
in RU. For backward compatibility the computed checksum is appended
at the end of the data posted to Rx buffer. This type of simple
checksum calculation support had been used on several vendors such
as Sun HME/GEM, SysKonnect GENESIS and Marvell Yukon controllers.
Because this type of checksum offload support requires parsing of
received frame and pseudo checksum calculation with software
routine it still consumes more CPU cycles than that of full-fledged
checksum offload controller. But it's still better than software
checksum calculation.
Rx buffer and loads DMA map. Also add a function
fxp_discard_rfabuf that handles reusing Rx buffer/DMA map. With
this change fxp_add_rfabuf just handles appending a new RFA to
existing chain.
o Initialize mbuf length in fxp_new_rfabuf.
o Don't reset rnr and have fxp(4) handle received frames even if
it couldn't allocate new Rx buffer. This will make fxp(4) reload
updated RFA under rnr case. The rnr would still be reset to 0 if
polling is active and fxp(4) processed number of allowed Rx
events.
o Update if_iqdrops if fxp(4) couldn't allocate Rx buffer.
Previously fxp(4) used to try to reuse Rx buffer when new buffer
allocation is failed. But fxp(4) didn't take into account loaded
DMA map such that the same DMA map was loaded again without
unloading the map. There is no reason to unload the loaded map and
reload the same map again, just reusing the map is enough. I
believe the spare DMA map in softc was introduced to implement this
behaviour. Also fxp(4) used to stop Rx processing if once Rx buffer
allocation or DMA map load fails which in turn resulted in losing
incoming frames under heavy network load. With this change fxp(4)
should survive from resource shortage condition.

Instead of initializing the affected global variables at instatiation,

Essentialy, this change should have zero functional impact. In the next

L2E(AR8113/AR8114). Unlike its predecessor Attansic L1,
AR8121/AR8113/AR8114 uses completely different Rx logic such that
it requires separate driver. Datasheet for AR81xx is not available
to open source driver writers but it shares large part of Tx and
PHY logic of L1. I still don't understand some part of register

The AR81xx requires copy operation to pass received frames to upper

global row indices before invoking class dependent operations.

On RELENG_6 (and probably RELENG_7) we see our syscons windows and
pseudo-terminals have the following buffer sizes:
| LINE RAW CAN OUT IHIWT ILOWT OHWT LWT COL STATE SESS PGID DISC
| ttyv0 0 0 0 7680 6720 2052 256 7 OCcl 1146 1146 term
| ttyp0 0 0 0 7680 6720 1296 256 0 OCc 82033 82033 term
These buffer sizes make no sense, because we often have much more output
than input, but I guess having higher input buffer sizes improves
guarantees of the system.
On MPSAFE TTY I just sent both the input and output buffer sizes to 7
KB, which is pretty big on a standard FreeBSD install with 8 syscons
windows and some PTY's. Reduce the baud rate to 9600 baud, which means
we now have the following buffer sizes:
| LINE INQ CAN LIN LOW OUTQ USE LOW COL SESS PGID STATE
| ttyv0 1920 0 0 192 1984 0 199 7 2401 2401 Oil
| pts/0 1920 0 0 192 1984 0 199 5631 1305 2526 Oi
This is a lot smaller, but for pseudo-devices this should be good
enough. You need to do a lot of punching to fill up a 7.5 KB input
buffer. If it turns out things don't work out this way, we'll just
switch to 19200 baud.
NATM needs 'struct in_addr' to compile, which is a problem on its own

Because the TTY hooks interface was not finished when I imported the
MPSAFE TTY layer, I had to disconnect the snp(4) driver. This snp(4)
implementation has been sitting in my P4 branch for some time now.
Unfortunately it still doesn't use the same error handling as snp(4)
(returning codes through FIONREAD), but it should already be usable.
I'm committing this to SVN, hoping someone else could polish off its
rough edges. It's always better than having a broken driver sitting in
the tree.
Note that these changes will not make the driver work on powerpc, but it should fix at least the i386/amd64 cases.

vnode in question does not need to be held. All the data structures used
during the name lookup are protected by the global name cache lock.
Instead, the caller merely needs to ensure a reference is held on the
vnode (such as vhold()) to keep it from being freed.
In the case of procfs' <pid>/file entry, grab the process lock while we
gain a new reference (via vhold()) on p_textvp to fully close races with
execve(2).
For the kern.proc.vmmap sysctl handler, use a shared vnode lock around
the call to VOP_GETATTR() rather than an exclusive lock.

This commit includes a more or less complete rewrite of the *BSD USB
stack, including Host Controller and Device Controller drivers and
updating all existing USB drivers to use the new USB API:
1) A brief feature list:
- A new and mutex enabled USB API.
- Many USB drivers are now running Giant free.
- Linux USB kernel compatibility layer.
- New UGEN backend and libusb library, finally solves the "driver
unloading" problem. The new BSD licensed libusb20 library is fully
compatible with libusb-0.1.12 from sourceforge.
- New "usbconfig" utility, for easy configuration of USB.
- Full support for Split transactions, which means you can use your
full speed USB audio device on a high speed USB HUB.
- Full support for HS ISOC transactions, which makes writing drivers
for various HS webcams possible, for example.
- Full support for USB on embedded platforms, mostly cache flushing
and buffer invalidating stuff.
- Safer parsing of USB descriptors.
- Autodetect of annoying USB install disks.
- Support for USB device side mode, also called USB gadget mode,
using the same API like the USB host side. In other words the new
USB stack is symmetric with regard to host and device side.
- Support for USB transfers like I/O vectors, means more throughput
and less interrupts.
- ... see the FreeBSD quarterly status reports under "USB project"
2) To enable the driver in the default kernel build:
2.a) Remove all existing USB device options from your kernel config
file.
2.b) Add the following USB device options to your kernel configuration
file:
# USB core support
device usb2_core
# USB controller support
device usb2_controller
device usb2_controller_ehci
device usb2_controller_ohci
device usb2_controller_uhci
# USB mass storage support

# USB ethernet support, requires miibus

device usb2_ethernet_rue
device usb2_ethernet_dav
# USB wireless LAN support
device usb2_wlan
device usb2_wlan_rum
device usb2_wlan_ral
device usb2_wlan_zyd
# USB serial device support
device usb2_serial
device usb2_serial_ark
device usb2_serial_bsa
device usb2_serial_bser
device usb2_serial_chcom
device usb2_serial_cycom
device usb2_serial_foma
device usb2_serial_ftdi
device usb2_serial_gensa
device usb2_serial_ipaq
device usb2_serial_lpt
device usb2_serial_mct
device usb2_serial_modem
device usb2_serial_moscom
device usb2_serial_plcom
device usb2_serial_visor
device usb2_serial_vscom
# USB bluetooth support
device usb2_bluetooth
device usb2_bluetooth_ng
# USB input device support
device usb2_input
device usb2_input_hid
device usb2_input_kbd
device usb2_input_ms
# USB sound and MIDI device support
device usb2_sound
2) To enable the driver at runtime:
2.a) Unload all existing USB modules. If USB is compiled into the
kernel then you might have to build a new kernel.
2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same
base name like the kernel device option.

For an unknown reason the touch pad of my PowerBook generates button 5
events when you operate it. This causes the adb_mouse code to convert
them to button 2 events, which is not what we want.
Add a new flag, AMS_TOUCHPAD, which is used to distinguish the touch
pad. When set, don't convert button events of unknown buttons to the
last button.
There are still three problems left with respect to user input:
- The mouse button events are not properly processed when the touch pad
isn't touched.
- The arrow keys on the keyboard don't work inside X11.
- The power button isn't handled by the kernel, similar to the ACPI
power button on i386/amd64.

use process ID as ACPI thread ID. Concurrent requests with equal thread
IDs broke ACPI mutexes operation causing unpredictable errors including
AE_AML_MUTEX_NOT_ACQUIRED that I have seen.
Use kernel thread ID instead of process ID for ACPI thread.
Right now ams_read() uses cv_wait() to wait for new data to arrive on
the mouse device. This means that when you run `cat /dev/ams0', it
cannot be interrupted directly. After you press ^C, you first need to
move the mouse before cat will quit. Make this function use
cv_wait_sig(), which allows it to be interrupted directly.

only checking the ap capabilities which meant that if an ap reported
it was ff-capable but we were not setup to use them we'd try to do
ff aggregation and drop the frame.

Olaf Kirch noticed that the i915_set_status_page() function of the i915
kernel driver calls ioremap with an address offset that is supplied by
userspace via ioctl. The function zeroes the mapped memory via memset
and tells the hardware about the address. Turns out that access to that
ioctl is not restricted to root so users could probably exploit that to
do nasty things. We haven't tried to write actual exploit code though.
