commit c3e2a5f2da904a18661335e8be2b961738574998 upstream.

The previous check for the is_vsc_sdp_colorimetry_supported flag
for MST sink signals did nothing. Simplify the code and use the
same check for MST and SST.

<content type='text'>
commit 9e61ef8d219877202d4ee51d0d2ad9072c99a262 upstream.

In order for display colorimetry to work correctly on DP displays
we need to send the VSC SDP packet. We should only do so for
panels with DPCD revision greater or equal to 1.4 as older
receivers might have problems with it.

commit 8b2be55f4d6c1099d7f629b0ed7535a5be788c83 upstream.

For SOC21 ASICs, there is an issue in re-enabling PM features if a
suspend got aborted. In such cases, reset the device during resume
phase. This is a workaround till a proper solution is finalized.

commit 8bdfb4ea95ca738d33ef71376c21eba20130f2eb upstream.

Currently, with F32 HWS GPU reset is only when unmap queue fails.

However, if compute queue doesn't repond to preemption request in time
unmap will return without any error. In this case, only preemption error
is logged and Reset is not triggered. Call GPU reset in this case also.

commit 31729e8c21ecfd671458e02b6511eb68c2225113 upstream.

While doing multiple S4 stress tests, GC/RLC/PMFW get into
an invalid state resulting into hard hangs.

Adding a GFX reset as workaround just before sending the
MP1_UNLOAD message avoids this failure.

commit 03c6284df179de3a4a6e0684764b1c71d2a405e2 upstream.

This patch causes the following iounmap erorr and calltrace
iounmap: bad address 00000000d0b3631f

The original patch was unjustified because amdgpu_device_fini_sw() will
always cleanup the rmmio mapping.

[ Upstream commit eb4f139888f636614dab3bcce97ff61cefc4b3a7 ]

This ensures that the memory mapped by ioremap for adev-&gt;rmmio, is
properly handled in amdgpu_device_init(). If the function exits early
due to an error, the memory is unmapped. If the function completes
successfully, the memory remains mapped.
