This reverts commit d6e020819612a4a06207af858e0978be4d3e3140.
The IS_DGFX check was put in place because error capture of buffer
objects is expected to be broken on devices with VRAM.
Userspace fix[1] to the impacted media driver has been submitted, merged
and a new driver release is out as 25.2.3 where the capture flag is
dropped on DG1 thus unblocking the usage of media driver on DG1.

The intel-media-driver is currently broken on DG1 because
it uses EXEC_CAPTURE with recovarable contexts. Relax the
check to allow that.

Pull core x86 updates from Ingo Molnar:
"Boot code changes:
- A large series of changes to reorganize the x86 boot code into a
better isolated and easier to maintain base of PIC early startup
code in arch/x86/boot/startup/, by Ard Biesheuvel.
Motivation & background:
| Since commit
|
| c88d71508e36 ("x86/boot/64: Rewrite startup_64() in C")
|
| dated Jun 6 2017, we have been using C code on the boot path in a way
| that is not supported by the toolchain, i.e., to execute non-PIC C
| code from a mapping of memory that is different from the one provided
| to the linker. It should have been obvious at the time that this was a
| bad idea, given the need to sprinkle fixup_pointer() calls left and
| right to manipulate global variables (including non-pointer variables)
| without crashing.
|
| This C startup code has been expanding, and in particular, the SEV-SNP
| startup code has been expanding over the past couple of years, and
| grown many of these warts, where the C code needs to use special
| annotations or helpers to access global objects.
This tree includes the first phase of this work-in-progress x86

Adjust the enabling/disabling steps of the DP audio SDP splitting
according to a recent Bspec update. This moves the enabling to the audio
codec enable sequence after the transcoder is enabled and disables SDP
splitting explicitly during the audio disable sequence.
Bspec requires waiting for a vblank event after the transcoder is
enabled and before SDP splitting is enabled. There is no need for an
explicit wait for this, since after the transcoder is enabled this
vblank event is guaranteed to have happened via a flip done wait (see
intel_atomic_commit_tail() -> drm_atomic_helper_wait_for_flip_done()).
The bspec update is for LNL+ only, but the HW team clarified that this
has been always the intended sequence on all platforms and bspec will be
updated everywhere accordingly.
The way SDP splitting was originally enabled matched the version of
bspec at that time. Adding here the Fixes: line still, since this
change fixes a FIFO underrun on PTL during output enabling when DSC is
enabled.
Bspec: 49283, 68943

Platforms that do not support SLPC are exempted from the GuC PC support.
The GuC PC does not get initialized, and neither do its BOs get created.
This causes a problem because the GuC PC debugfs file is still being
created. Whenever the file is attempted to read, it causes a NULL
pointer dereference on the supposed BO of the GuC PC.
So, make the creation of SLPC debugfs files conditional to when SLPC
features are supported.

Under specific embedded scenarios, we might still use DP interface
rather than eDP interface. Under such case, detection link training
is unnecessary.
Add a new dcdebugmask value that can be used to skip the detection LT

The current cleanup order during file descriptor close can lead to
a race condition where the eviction fence worker attempts to access
a destroyed mutex from the user queue manager:
[ 517.294055] DEBUG_LOCKS_WARN_ON(lock->magic != lock)
[ 517.294060] WARNING: CPU: 8 PID: 2030 at kernel/locking/mutex.c:564
[ 517.294094] Workqueue: events amdgpu_eviction_fence_suspend_worker [amdgpu]
The issue occurs because:
1. We destroy the user queue manager (including its mutex) first
2. Then try to destroy eviction fences which may have pending work
3. The eviction fence worker may try to access the already-destroyed mutex
Fix this by reordering the cleanup to:
1. First mark the fd as closing and destroy eviction fences,
which flushes any pending work
2. Then safely destroy the user queue manager after we're certain
no more fence work will be executed
The copy in amdgpu_driver_postclose_kms() needs to be removed (Christian)
