[PATCH AUTOSEL 5.4 04/74] drm/amd/amdgpu/sriov disable all ip hw status by default

[PATCH AUTOSEL 5.4 04/74] drm/amd/amdgpu/sriov disable all ip hw status by default

[Sasha Levin]

From: Jack Zhang <Jack.Zhang1@amd.com>

[ Upstream commit 95ea3dbc4e9548d35ab6fbf67675cef8c293e2f5 ]

Disable all ip's hw status to false before any hw_init.
Only set it to true until its hw_init is executed.

The old 5.9 branch has this change but somehow the 5.11 kernrel does
not have this fix.

Without this change, sriov tdr have gfx IB test fail.

[PATCH AUTOSEL 5.4 07/74] drm/amd/display: fix use_max_lb flag for 420 pixel formats

[Sasha Levin]

From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>

[ Upstream commit 8809a7a4afe90ad9ffb42f72154d27e7c47551ae ]

Right now the flag simply selects memory config 0 when flag is true
however 420 modes benefit more from memory config 3.

[PATCH AUTOSEL 5.4 35/74] drm/amd/display: Update scaling settings on modeset

[Sasha Levin]

From: Roman Li <roman.li@amd.com>

[ Upstream commit c521fc316d12fb9ea7b7680e301d673bceda922e ]

[Why]
We update scaling settings when scaling mode has been changed.
However when changing mode from native resolution the scaling mode previously
set gets ignored.

[How]
Perform scaling settings update on modeset.

[PATCH AUTOSEL 5.4 36/74] drm/amd/display: Release MST resources on switch from MST to SST

[Sasha Levin]

From: Vladimir Stempen <vladimir.stempen@amd.com>

[ Upstream commit 3f8518b60c10aa96f3efa38a967a0b4eb9211ac0 ]

[why]
When OS overrides training link training parameters
for MST device to SST mode, MST resources are not
released and leak of the resource may result crash and
incorrect MST discovery during following hot plugs.

[how]
Retaining sink object to be reused by SST link and
releasing MST  resources.
