2017-08-29drm/amdgpu: Add debugfs file for VBIOS and versionKent Russell3-1/+67
Add 2 debugfs files, one that contains the VBIOS version, and one that contains the VBIOS itself. These won't change after initialization, so we can add the VBIOS version when we parse the atombios information. This ensures that we can find out the VBIOS version, even when the dmesg buffer fills up, and makes it easier to associate which VBIOS version is for which GPU on mGPU configurations. Set the size to 20 characters in case of some weird VBIOS version that exceeds the expected 17 character format (3-8-3\0). The VBIOS dump also allows for easy debugging v2: Move to debugfs, clarify commit message, add VBIOS dump file Signed-off-by: Kent Russell <[email protected]> Reviewed-by: Alex Deucher <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2017-08-29drm/amdgpu: set sched_hw_submission higher for KIQ (v3)Alex Deucher1-4/+12
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 performance when there are several KFD processes running. v2: move some expressions to one line change KIQ sched_hw_submission to at least 16 v3: bump to 256 Reviewed-by: Christian König <[email protected]> Reviewed-by: Felix Kuehling <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
