[PATCH 24/29] drm/amdgpu: suspend for each vcn instance

boyuan.zhang at amd.com boyuan.zhang at amd.com
Tue Oct 29 17:42:35 UTC 2024


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

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

v2: add vcn instance to amdgpu_vcn_save_vcpu_bo()
