[PATCH 23/32] drm/amdgpu: hw_init for each vcn instance

boyuan.zhang at amd.com boyuan.zhang at amd.com
Tue Oct 8 21:15:44 UTC 2024


From: Boyuan Zhang <boyuan.zhang at amd.com>

Pass instance parameter to amdgpu_vcn_hw_init(), and perform
hw init ONLY for the given vcn instance, instead of for all
vcn instances. Modify each vcn generation accordingly.
