drm/amd: Use `amdgpu_ucode_*` helpers for MES

2023-01-09T22:02:18Z

The `amdgpu_ucode_request` helper will ensure that the return code for missing firmware is -ENODEV so that early_init can fail. The `amdgpu_ucode_release` helper provides symmetry for releasing firmware. Reviewed-by: Alex Deucher Reviewed-by: Lijo Lazar Signed-off-by: Mario Limonciello Signed-off-by: Alex Deucher

drm/amd: Load MES microcode during early_init

2023-01-09T22:02:18Z

Add an early_init phase to MES for fetching and validating microcode from the filesystem. If MES microcode is required but not available during early init, the firmware framebuffer will have already been released and the screen will freeze. Move the request for MES microcode into the early_init phase so that if it's not available, early_init will fail.

drm/amdgpu/mes: zero the sdma_hqd_mask of 2nd SDMA engine for SDMA 6.0.1

2022-09-14T19:00:34Z

there is only one SDMA engine in SDMA 6.0.1, the sdma_hqd_mask has to be zeroed for the 2nd engine, otherwise MES scheduler will consider 2nd engine exists and map/unmap SDMA queues to the non-existent engine. Signed-off-by: Yifan Zhang Reviewed-by: Tim Huang Signed-off-by: Alex Deucher
