Re: [PATCH] drm/amdgpu: set sched_hw_submission higher for KIQ (v2)

As noted in the otehr thread we could set it to 256 as well and still only use one page, but 16 is fine with me as well. Patch is Reviewed-by: Christian König Regards, Christian. Am 23.08.2017 um 04:25 schrieb Felix Kuehling: This change is Reviewed-by: Felix

[PATCH] drm/amdgpu: set sched_hw_submission higher for KIQ (v2)

KIQ doesn't really use the GPU scheduler. The base drivers generally use the KIQ ring directly rather than submitting IBs. However, amdgpu_sched_hw_submission (which defaults to 2) limits the number of outstanding fences to 2. KFD uses the KIQ for TLB flushes and the 2 fence limit hurts

Thanks Alex! Jay, do you think this is enough? This bumps the number of concurrent operations on KIQ to 4 by default. Regards, Felix On 2017-08-22 04:49 PM, Alex Deucher wrote: > KIQ doesn't really use the GPU scheduler. The base > drivers generally use the KIQ ring directly rather than >
