[PATCH 23/29] drm/amdgpu: hw_init for each vcn instance
boyuan.zhang at amd.com
boyuan.zhang at amd.com
Fri Oct 25 02:35:39 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.
