drm/amdgpu: load sdma ucode in the guest machine

2023-07-25T17:47:26+00:00

[why] User mode driver need to check the sdma ucode version to see whether the sdma engine supports a new type of PM4 packet. In SRIOV, sdma is loaded by the host. And, there is no way to check the sdma ucode version of CHIP_NAVI12 and CHIP_SIENNA_CICHLID of the host in the guest machine. [how] Load the sdma ucode for CHIP_NAVI12 and CHIP_SIENNA_CICHLID in the guest machine. Signed-off-by: YuanShang Reviewed-By: Horace Chen Signed-off-by: Alex Deucher

drm/amdgpu: set sw state to gfxoff after SR-IOV reset

2023-07-25T17:35:23+00:00

[Why] Current SR-IOV will not set GC to off state, while it is a real GC hard reset. Whthout GFX off flag, driver may do gfxhub invalidation before firmware load and gfxhub gart enable. This operation may cause CP to become busy because GC is not in the right state for invalidation. [How] Add a function for SR-IOV to clean up some sw state before recover. Set adev->gfx.is_poweron to false to prevent gfxhub invalidation before gfx firmware autoload complete. Signed-off-by: Horace Chen Reviewed-by: HaiJun Chang Signed-off-by: Alex Deucher
