[PATCH 3/5] drm/amdgpu: Add mask for SDMA instances

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

 



From: Lijo Lazar <lijo.lazar@xxxxxxx>

Add a mask of SDMA instances available for use. On certain ASIC configs,
not all SDMA instances are available for software use.

	Change sdma mask type to uint32_t (Le)
