[PATCH 17/29] drm/amdgpu: power vcn 5_0_0 by instance
boyuan.zhang at amd.com
boyuan.zhang at amd.com
Tue Oct 29 17:42:28 UTC 2024
From: Boyuan Zhang <boyuan.zhang at amd.com>
For vcn 5_0_0, add ip_block for each vcn instance during discovery stage.
And only powering on/off one of the vcn instance using the
instance value stored in ip_block, instead of powering on/off all
vcn instances. Modify the existing functions to use the instance value
in ip_block, and remove the original for loop for all vcn instances.
v2: rename "i"/"j" to "inst" for instance value.
