[PATCH 85/88] drm/amdgpu: drop AMDGPU_FENCE_SIGNALED_SEQ

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

 



From: Christian König <christian.koenig@xxxxxxx>

It's causing issues with VMID handling and comparing the
fence value two times actually doesn't make handling faster.

Port of radeon commit "d6d5c5b8364bcc4d52cddc68bcb0a330d2af20f3".
