[PATCH v6 16/45] drm/amd: Use `amdgpu_ucode_*` helpers for GFX10

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 is for symmetry on unload.
