c6d4a099a2 drm/i915: reimplement header test feature 
I implemented a small build rule in drivers/gpu/drm/i915/Makefile
without relying on the special header-test-y syntax that was removed in
commit fcbb8461fd ("kbuild: remove header compile test").

I excluded some headers from the test coverage. I hope somebody
intrested can take a closer look at them.

Dummy subdir Makefiles can be removed altogether as single target build
use case is now covered by commit 394053f4a4 ("kbuild: make single
targets work more correctly").

v2 by Jani:
- add selftests/i915_perf_selftests.h to no-header-test
- add .gitignore for *.hdrtest

f17b898009 drm/i915/gem: Drop local vma->vm_file reference 
We use the global device inode, shared amongst all files, and not the
user's device filp to provide the backing storage for the mmap. The
vma->vm_file provides a redundant reference that breaks existing
expected behaviour that closing the user's device fd will release the
resources bound to it, if a mmap persists. (Even without the
vma->vm_file, the mmap will persist past the user's fd as the storage is
bound to the device, i.e. our reference is on the object not file.)

969e115292 drm/amdgpu: correct RLC firmwares loading sequence 
Per confirmation with RLC firmware team, the RLC should
be unhalted after all RLC related firmwares uploaded.
However, in fact the RLC is unhalted immediately after
RLCG firmware uploaded. And that may causes unexpected
PSP hang on loading the succeeding RLC save restore
list related firmwares.
So, we correct the firmware loading sequence to load
RLC save restore list related firmwares before RLCG
ucode. That will help to get around this issue.

32f408ac3e drm/i915/gt: Restore coarse power gating 
The coarse power gating was disabled as part of commit 2248a28384
("drm/i915/gen8+: Add RC6 CTX corruption WA") as a prelude to recover
from the context corruption; the power gating itself has no direct
impact on the RC6 context corruption. However, that recovery scheme was
never implemented due to difficult corner cases, and so we no longer need
to keep the power gating disabled.

cf1d0180f5 drm/fbdev: Fallback to non tiled mode if all tiles not present 
In case of tiled displays, if we hotplug just one connector,
fbcon currently just selects the preferred mode and if it is
tiled mode then that becomes a problem if rest of the tiles are
not present.
So in the fbdev driver on hotplug when we probe the client modeset,
if we dont find all the connectors for all tiles, then on a connector
with one tile, just fallback to the first available non tiled mode
to display over a single connector.
On the hotplug of the consecutive tiled connectors, if the tiled mode
no longer exists because of fbcon size limitation, then return
no modes for consecutive tiles but retain the non tiled mode
on the 0th tile.
Use the same logic in case of connected boot case as well.
This has been tested with Dell UP328K tiled monitor.

v3:
* Check Num tiled conns that are connected (Manasi)
v2:
* Set the modes on consecutive hotplugged tiles to no mode
if tiled mode is pruned (Dave)
v1:
* Just handle the 1st connector hotplug case

it's about and it's shorter, so it doesn't go over 80 columns in a few
cases. This converts tigerlake to tgl where appropriate.

640b50fa8c drm/i915: Restore very early GPU reset 
In commit d03b224f42 ("drm/i915/gt: Apply sanitiization just before
resume") the GT sanitization was pulled into the resume path as we need
to know the backend in order to do a full reset prior to resume.
However, it is still imperative that we scrub existing GPU state before
clobbering in our early setup, so restore a minimal GPU reset at the
start of our init sequence.
