[PATCH 07/18] drm/amdgpu/vcn: separate gating state by instance
boyuan.zhang at amd.com

Wed Oct 2 04:36:16 UTC 2024
From: Boyuan Zhang <boyuan.zhang at amd.com>
vcn gating state should now be based on instance. For example, instance 0
can be gated while instance 1 is ungated, or vice versa.
Therefore, change the cur_state to be an array, so that it can track the
gating status for each vcn instance now.
