[PATCH] drm/amdgpu: Fix firmware UCODE_ID_STORAGE issue

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

 



In Tonga's virtualization environment, for firmware UCODE_ID_STORAGE,
there is no actual firmware data, but we still need alloc a BO and
tell the BO's mc address to HW, or world switch will hang on VFs.
