Build and sysctl configuration modes are introduced for QAT SPR
devices to disable safe dc mode. A new QAT driver build option
‘QAT_DISABLE_SAFE_DC_MODE’ is required to build the QAT driver
with code that allows a request to be sent to FW to override the
‘History Buffer’ mitigation. Default QAT driver builds do not
include this ‘QAT_DISABLE_SAFE_DC_MODE’ build option. Even if the
QAT driver was built with code that allows a request to be sent to
FW to override the ‘History Buffer’ mitigation, the QAT driver must
still be configured using sysctl to request an override of the
‘History Buffer’ mitigation if desired. The default QAT driver
configuration option sysctl dev.qat.X.disable_safe_dc_mode does not
allow override of the mitigation. The new sysctl attribute
disable_safe_dc_mode is to be set to 1 for overriding the history
buffer mitigation. Firmware for qat_4xxx is updated for this change.
If this mode is enabled, decompression throughput increases but may
result in a data leak if num_user_processes is more than 1.
This option is to be enabled only if your system is not prone to
user data leaks.

(cherry picked from commit 5a8e5215cef0dac1115853889e925099f61bb5fa)
This is derived from swills@ fork of the Juniper virtfs with many
changes by me including bug fixes, style improvements, clearer layering
and more consistent logging. The filesystem is renamed to p9fs to better
reflect its function and to prevent possible future confusion with
virtio-fs.
Several updates and fixes from Juniper have been integrated into this
version by Val Packett and these contributions along with the original
Juniper authors are credited below.
To use this with bhyve, add 'virtio_p9fs_load=YES' to loader.conf. The
bhyve virtio-9p device allows access from the guest to files on the host
by mapping a 'sharename' to a host path. It is possible to use p9fs as a
root filesystem by adding this to /boot/loader.conf:
vfs.root.mountfrom="p9fs:sharename"
for non-root filesystems add something like this to /etc/fstab:
sharename /mnt p9fs rw 0 0
In both examples, substitute the share name used on the bhyve command
line.
The 9P filesystem protocol relies on stateful file opens which map
protocol-level FIDs to host file descriptors. The FreeBSD vnode
interface doesn't really support this and we use heuristics to guess the
right FID to use for file operations. This can be confused by privilege
lowering and does not guarantee that the FID created for a given file
open is always used for file operations, even if the calling process is
using the file descriptor from the original open call. Improving this
would involve changes to the vnode interface which is out-of-scope for
this import.

Following the example of rtw88 and rtw89 only ship iwlwifi firmware
from ports/packages. Users are asked to run fwget(8) to install the
firmware needed for their system or build it from ports
(see also UPDATING).
This is the end of a long story adding wireless support to fwget(8),
migrating the firmware for multiple branches into ports, splitting them
up into flavors, and updating some install media and the installer to
provide firmware.
The overall amount for new firmware amongst all drivers would have
added more than 100M of binary blobs to src.git for the first import,
ignoring future updates which (along with some duplication between
multiple drivers) was considered too much.
While maintenance within the src tree certainly would have been
easier in the longer term this seems to be the better solution and
I would like to thank everyone who helped along the path to get there.
The iwlwififw.4 man page is to stay (for now) and will likely point
at the appropriate firmware package flavor in the future as well
so people may find it easier to transition. In the long term this
information is likely not needed anymore.

DQO is the descriptor format for our next generation virtual NIC.
It is necessary to make full use of the hardware bandwidth on many
newer GCP VM shapes.
One major change with DQO from its predecessor GQI is that it uses
dual descriptor rings for both TX and RX queues.
The TX path uses a descriptor ring to send descriptors to HW, and
receives packet completion events on a TX completion ring.
The RX path posts buffers to HW using an RX descriptor ring and
receives incoming packets on an RX completion ring.
In GQI-QPL, the hardware could not access arbitrary regions of
guest memory, which is why there was a pre-negotitated bounce buffer
(QPL: Queue Page List). DQO-RDA has no such limitation.
"RDA" is in contrast to QPL and stands for "Raw DMA Addressing" which
just means that HW does not need a fixed bounce buffer and can DMA
arbitrary regions of guest memory.
A subsequent patch will introduce the DQO-QPL datapath that uses the
same descriptor format as in this patch, but will have a fixed
bounce buffer.

Changes to acpi_gpiobus.c handle discovering and parsing the _AEI
objects and storing necessary data in device ivars. A new gpioaei.c
file implements the device, which simply requests an interrupt when
the pin is triggered and invokes the appropriate _Exx or _Lxx ACPI
method.
This makes the GPIO "power button" work on arm64 Graviton systems,
allowing EC2 "Stop"/"Reboot" instance calls to be handled cleanly.
(Prior to this change, those requests would time out after 4 minutes
and the instance would be forcibly killed.)

Armv8.5 adds an optional random number generator. This is implemented
as two special registers one to read a random number, the other to
re-seed the entropy pool before reading a random number. Both registers
will set the condition flags to tell the caller they can't produce a
random number in a reasonable amount of time.
Without a signal to reseed the entropy pool use the latter register
to provide random numbers to the kernel pool. If at a later time we
had a way to tell the provider if it needs to reseed or not we could
use the former.
On an Amazon AWS Graviton3 VM this never failed, however this may not
be the case on low end CPUs so retry reading the random number 10 times
before returning an error.

This was done in the original DTrace import, presumably because that
made it a bit easier to handle includes. However, this can cause
dtrace_getpcstack() to be inlined into dtrace_probe(), resulting in a
missing frame in stack traces since dtrace_getpcstack() takes care to
bump "aframes" to account for its own stack frame.
To avoid this, compile dtrace_isa.c separately on all platforms. Add
requisite includes.
