[PATCH] drm/amdgpu: cleanup VMHUB bit definitions v2

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

 



From: Christian König <christian.koenig@xxxxxxx>

The two hubs are just instances of the same hardware,
so the register bits are identical.

v2: only remove get_vm_protection_bits for now
