[PATCH AUTOSEL 6.1 06/10] drm/amd/pm: skip the RLC stop when S0i3 suspend for SMU v13.0.4/11

[Sasha Levin]

From: Tim Huang <Tim.Huang@amd.com>

[ Upstream commit 730d44e1fa306a20746ad4a85da550662aed9daa ]

For SMU v13.0.4/11, driver does not need to stop RLC for S0i3,
the firmwares will handle that properly.

[PATCH AUTOSEL 6.1 07/10] drm/amdgpu: Match against exact bootloader status

[Sasha Levin]

From: Lijo Lazar <lijo.lazar@amd.com>

[ Upstream commit d3de41ee5febe5c2d9989fe9810bce2bb54a3a8e ]

On PSP v13.x ASICs, boot loader will set only the MSB to 1 and clear the
least significant bits for any command submission. Hence match against
the exact register value, otherwise a register value of all 0xFFs also
could falsely indicate that boot loader is ready. Also, from PSP v13.0.6
and newer, bits[7:0] will be used to indicate command error status.

From: Alex Deucher <alexander.deucher@amd.com>

[ Upstream commit a6dea2d64ff92851e68cd4e20a35f6534286e016 ]

We are dropping the IOMMUv2 path, so no need to enable this.
It's often buggy on consumer platforms anyway.

[PATCH AUTOSEL 6.1 09/10] drm/amdkfd: disable IOMMUv2 support for KV/CZ

[Sasha Levin]

From: Alex Deucher <alexander.deucher@amd.com>

[ Upstream commit 616f92d188ee7142a95a52068efdbea82645f859 ]

Use the dGPU path instead.  There were a lot of platform
issues with IOMMU in general on these chips due to windows
not enabling IOMMU at the time.  The dGPU path has been
used for a long time with newer APUs and works fine.  This
also paves the way to simplify the driver significantly.

v2: use the dGPU queue manager functions
