[PATCH 07/18] drm/amdgpu/vcn: separate gating state by instance

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

 



From: Boyuan Zhang <boyuan.zhang@xxxxxxx>

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.
