Before unloading or unbinding an audio driver, all processes
that are using it must be terminated. The current logic seeks
only for alsactl, but ignore other processes, including
pulseaudio.
Make the logic more general, extending it to any processes that
could have an open device under /dev/snd.
It should be noticed that some distros like Fedora and openSUSE
are now migrating from pulseaudio into pipewire-pulse. Right
now, there's no standard distribution-agnostic way to request
pipewire-pulse to stop using audio devices, but there's a new
patch upstream that will make things easier:
https://gitlab.freedesktop.org/pipewire/pipewire/-/commit/6ad6300ec657c88322a8cd6f3548261d3dc05359
Which should be available for pipewire-pulse versions 0.3.50 and
upper.

Add silent __igt_i915_driver_unload(), which will not
print any warning in case of passed argument is NULL.
This will be used by some igt test, which marks i915
module busy and expect i915 module unload to fail.
These tests requires a silent lib function to unload
the i915 module correctly.
v2:
- Change commit log. [Ashutosh]
- Change whom to who. [Ashutosh]
- When aux audule unload fails mark who with module name. [Ashutosh]
- Keep same type of return type in
__igt_i915_driver_unload(). [Ashutosh]

Our list was something between Wayland and Linux Kernel list
implementations, right in the uncanny valley.
On top of that it falsely claimed that it's a straight copy from the
Wayland project.
Let's make our impl more akin to the kernel one to ease the cognitive
dissonance for the developers working on all those projects.
This patch:
* mimics the current kernel list interface
* separates IGT helpers in the source files
* adds brief explanation and code example for igt-doc
* introduces igt_list.c as static inlines are not visible in the docs
v2: mimic the kernel instead of wayland (Chris)
- _head suffix for the sentinel/link struct
- _entry_ in iterator names that go over the elements
v3: I forgot to merge this in time and there was another call site
that had to be converted in gem_spin_batch.c

Name of the i915 module parameter providing fault injection function is
changing for consistency with a new convention of naming i915 driver
internal functions called from the driver PCI .probe entry point. Adjust
the test to use the new name.
[ickle: keep the old parameter name around for stable testing]

An hanging batch is nothing more than a spinning batch that never gets
stopped, so re-use the routines implemented in dummyload.c.
v2: Let caller decide spin loop size
v3: Only use loose loops for hangs (Chris)
v4: No requires
v5: Free the spinner
v6: Chamelium exists.

This patch gets rid of the Android support, deleting all the hacks and
moving code around to the places it belongs.
Android build is not really maintained properly and rots rather fast.
With recent push for Meson here and Android going for Soong it will only
accelerate.
It's a good time to drop the illusion of providing any support.

On Android libkmod.h is nested under libkmod directory, so we should
include appropriately.
Also we need to link with it.

For an as of yet unknown reason, calling system("modprobe") from inside
igt/gem_wait causes kasan to spend 1-5 minutes copying the process
pagetables. This evaporates if we replace the fork-happy call to system
with a call to load the module using libkmod. So be it.

Even when the running kernel does not support selftests, make subtest
enumeration list known kselftests. The list is generated using
selftest listing headers copied from the kernel.
If the running kernel gains new selftest subtests, they are listed
even without copying the headers over and rebuilding IGT.
v2: Use correct names for the testcases

"Live" selftesting of i915.ko happens during device probing which eats
the error code and does not propagate it back to module loading.
Workaround this by writing the error code back to the module parameter
and probing it after a "successful" install.

lib/igt_aux: Added igt_pkill and igt_lsof helper.
lib/igt_kmod: Added load/unload kmod helpers.
v7:
- document the case where leaving stray fd from drm_open_driver()
might fail reloading the driver.
- list also current opened files from /dev/dri in case we could not
unload the driver.
- convert igt_info to igt_warn (Chris Wilson)
- added KMOD_|PROCPS CFLAGS (Chris Wilson)
v6:
- include latest modifications from tests/drv_module_reload:
display all loaded modules and list information about opened
files by processes (Petri Latvala)
v5:
- added igt_i915_driver_{load/unload}.
- added kick_snd_hda_intel() to match current
tests/drv_module_reload_basic and integrated into
igt_i915_driver_load/unload.
- added gtk-doc section for lib/igt_kmod
v4:
- decided to split libkmod helpers into their own file as there's
another user lib/igt_gvt or tests/gvt_basic.
- fixed some gtk-doc documentation.
v3:
- return -errno (igt_pkill()) in case of failure (Cris Wilson)
- return bool for igt_kmod_is_loaded(), replaced strncasecmp with strncmp
(Chris Wilson)
v2:
- Renamed libkmod helpers (Chris Wilson)
- Removed SIGTERM/SIGKILL case where we repeatedly tried to terminate the
process: just call kill(2) once (Chris Wilson)
- Removed redundant check in igt_kmod_unload(), igt_module_in_use() (Chris
Wilson)
- Pass flags to igt_kmod_unload() from the caller (Chris Wilson)
- Removed useless function igt_kill() which acts just as kill(2) (Chris
