The code comes from the i915 DRM driver.
In Linux commits b739f125e4ebd73d10ed30a856574e13649119ed and
b12d691ea5e01db42ccf3b4207e57cb3ce7cfe91 (Linux 5.13), the i915 DRM
driver dropped specific implementations to use Linux generic functions.
Therefore I moved the FreeBSD code from that i915 driver to linuxkpi.
However, these commits were later reverted (also in Linux 5.13) so the
i915 driver doesn't use these functions. But perhaps it will help in the
future.
To sum up, the code comes from the i915 DRM driver but it doesn't use it
(i.e. it continues to use its internal implementation).

The scmi driver in its current form requires the arm_doorbell
driver to communicate with the firmware.
The arm_doorbell is only found in ARM Juno reference board (and
apparently on Morello too).
If we want to use scmi on other platform (like some rockchip or imx
soc), the driver needs to be updated to support svc/shmem communication
with the firmware.
For now since it can be only used with arm_doorbell move the device to
std.arm otherwise kernel configs like ALLWINNER or ROCKCHIP fails to build.

Ever since gtaskqueue_drain() was added to iflib_stop(), a kernel panic
occurs when the ice(4) driver is in recovery mode. Queues are not
initialized in this mode, so gt_taskqueue is not initialized, and
gtaskqueue_drain() will panic.
Fix this by only doing a drain if an RX queue's gt_taskqueue is
initialized.

Follow this scheme by passing the context argument down. Most drivers

Overview:
Intel(R) QuickAssist Technology (Intel(R) QAT) provides hardware
acceleration for offloading security, authentication and compression
services from the CPU, thus significantly increasing the performance and
efficiency of standard platform solutions.
This commit introduces:
- Intel® 4xxx Series platform support.
- QuickAssist kernel API implementation update for Generation 4 device.
Enabled services: symmetric cryptography and data compression.
- Increased default number of crypto instances in static configuration
for performance purposes.
OCF backend changes:
- changed GCM/CCM MAC validation policy to generate MAC by HW
and validate by SW due to the QAT HW limitations.

Start trying to make packet loss issues more visible by counting queue
drops in the transmit path, and in the input path for interfaces running
in emulated mode, where we place received packets in a bounded software

safeguard against calling bus_dmamap_sync() with a NULL map. The x86

This conditionally gives all registered shutdown handlers a chance to
perform the reboot, with cpu_reset() being the fallback. The '\s'
modifier can be used with the command to get the previous behaviour.
The motivation is that some platforms may not be able do anything
meaningful via cpu_reset(), due to a lack of standardized reset
mechanism and/or firmware shortcomings. However, they may have a
separate device driver attached that normally performs the reboot. Such
is the case for some versions of the Raspberry Pi, where reset via PSCI
fails, but the BCM2835 watchdog driver has a shutdown hook.

Currently shutdown_reset() is registered as the final entry of the
shutdown_final event handler. However, if a panic occurs early in boot
before the event is registered (SI_SUB_INTRINSIC), we may end up
spinning in the subsequent infinite for loop and failing to reset
altogether. Instead we can simply call this function unconditionally.
