I need the hw fence signaled before the following steps, and since I used a loop for that I cannot change to use force_completion() at all If you are picky on the duplication here, the good approach is removing the old force_completion(), and use force_completion() in all gpu reset routines That's clean way -----Original Message----- From: Koenig, Christian Sent: 2017å¹´10æ??9æ?¥ 16:41 To: Liu, Monk <Monk.Liu at amd.com>; amd-gfx at lists.freedesktop.org Subject: Re: [PATCH 08/12] drm/amdgpu:explicitly call fence_process We should avoid functionality duplication here. Either change the caller of amdgpu_fence_driver_force_completion_ring() to use amdgpu_fence_driver_force_completion() or use amdgpu_fence_driver_force_completion_ring() in amdgpu_fence_driver_force_completion(). The later is probably easier to do. Regards, Christian.
