This reverts commit 2daba7d857 which is
commit 73dae652dc upstream.
The original patch 73dae652dc (drm/amdgpu: rework resume handling for
display (v2)), was only targeted at kernels 6.11 and newer. It did not
apply cleanly to 6.12 so I backported it and it backport landed as
99a02eab82 ("drm/amdgpu: rework resume handling for display (v2)"),
however there was a bug in the backport that was subsequently fixed in
063d380ca2 ("drm/amdgpu: fix backport of commit 73dae652dcac"). None
of this was intended for kernels older than 6.11, however the original
backport eventually landed in 6.6, 6.1, and 5.15.
Please revert the change from kernels 6.6, 6.1, and 5.15.

commit 1a5401ec30 upstream.
Mesa changed its clear color alignment from 4k to 64 bytes
without informing the kernel side about the change. This
is now likely to cause framebuffer creation to fail.
The only thing we do with the clear color buffer in i915 is:
1. map a single page
2. read out bytes 16-23 from said page
3. unmap the page
So the only requirement we really have is that those 8 bytes
are all contained within one page. Thus we can deal with the
Mesa regression by reducing the alignment requiment from 4k
to the same 64 bytes in the kernel. We could even go as low as
32 bytes, but IIRC 64 bytes is the hardware requirement on
the 3D engine side so matching that seems sensible.
Note that the Mesa alignment chages were partially undone
so the regression itself was already fixed on userspace
side.

commit 1f9910b41c upstream.
The fence sync logic doesn't handle a fence sync across devices
as it tries to write to a channel offset from one device into
the fence bo from a different device, which won't work so well.
This patch fixes that to avoid using the sync path in the case
where the fences come from different nouveau drm devices.
This works fine on a single device as the fence bo is shared
across the devices, and mapped into each channels vma space,
the channel offsets are therefore okay to pass between sides,
so one channel can sync on the seqnos from the other by using
the offset into it's vma.

[ Upstream commit 902806baf3 ]
AUDIO_UPDATE bit (Bit 5 of MAIN register 0x4A) needs to be set to 1
while updating Audio InfoFrame information and then set to 0 when done.
Otherwise partially updated Audio InfoFrames could be sent out. Two
cases where this rule were not followed are fixed:
- In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated
before/after setting ADV7511_REG_AUDIO_INFOFRAME.
- In audio_startup() use the correct register for clearing
AUDIO_UPDATE bit.
The problem with corrupted audio infoframes were discovered by letting
a HDMI logic analyser check the output of ADV7535.
Note that this patchs replaces writing REG_GC(1) with
REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field
GC_PP[3:0] and that field doesn't control audio infoframe and is read-
only. My conclusion therefore was that the author if this code meant to
clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

[ Upstream commit 4641169a8c ]
A stream without dsc_aux should not be eliminated from
the dsc determination. Whether it needs a dsc recompute depends on
whether its mode has changed or not. Eliminating such a no-dsc stream
from the dsc determination policy will end up with inconsistencies
in the new dc_state when compared to the current dc_state,
triggering a dsc recompute that should not have happened.

[ Upstream commit b9b5a82c53 ]
[Why]
This fixes a bug introduced by commit c536555451 ("drm/amd/display: dsc
mst re-compute pbn for changes on hub").
The change caused light-up issues with a second display that required
DSC on some MST docks.
[How]
Use Virtual DPCD for DSC caps in MST case.
[Limitations]
This change only affects MST DSC devices that follow specifications
additional changes are required to check for old MST DSC devices such as
ones which do not check for Virtual DPCD registers.

When using MES creating a pdd will require talking to the GPU to
setup the relevant context. The code here forgot to wake up the GPU
in case it was in suspend, this causes KVM to EFAULT for passthrough
GPU for example. This issue can be masked if the GPU was woken up by
other things (e.g. opening the KMS node) first and have not yet gone to sleep.

I think this was an abstraction back from when
kfd supported both radeon and amdgpu. Since we just
support amdgpu now, there is no more need for this and
we can use the amdgpu structures directly.
This also avoids having the kfd_cu_info structures on
the stack when inlining which can blow up the stack.
