[PATCH] drm/amdgpu: update ib start and size alignment

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

 



From: Boyuan Zhang <boyuan.zhang@xxxxxxx>

Update IB starting address alignment and size alignment with correct values
for decode and encode IPs.

Decode IB starting address alignment: 256 bytes
Decode IB size alignment: 64 bytes
Encode IB starting address alignment: 256 bytes
Encode IB size alignment: 4 bytes

Also bump amdgpu driver version for this update.
