2019-10-30drm/amdkfd: Delete unnecessary pr_fmt switchYong Zhao1-4/+0
Given amdkfd.ko has been merged into amdgpu.ko, this switch is no longer useful. Signed-off-by: Yong Zhao <Yong.Zhao@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2019-10-03drm/amdkfd: Use array to probe kfd2kgd_callsYong Zhao1-7/+1
This is the same idea as the kfd device info probe and move all the probe control together for easy maintenance. Signed-off-by: Yong Zhao <Yong.Zhao@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2019-10-03drm/amdkfd: Eliminate get_atc_vmid_pasid_mapping_validYong Zhao1-4/+2
get_atc_vmid_pasid_mapping_valid() is very similar to get_atc_vmid_pasid_mapping_pasid(), so they can be merged into a new function get_atc_vmid_pasid_mapping_info() to reduce register access times. More importantly, getting the PASID and the valid bit atomically with a single read fixes some potential race conditions where the mapping changes between the two reads.

2019-10-03drm/amdkfd: Use better name for sdma queue non HWS pathYong Zhao1-43/+45
The old name is prone to confusion. The register offset is for a RLC queue rather than a SDMA engine. The value is not a base address, but a register offset.

2019-10-03drm/amdkfd: Delete useless SDMA register setting on non HWS pathYong Zhao1-33/+1
HW folks have confirm that we should not touch RESUME_CTX of SDMA*_GFX_CONTEXT_CNTL when manipulating RLC queues. Signed-off-by: Yong Zhao <Yong.Zhao@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2019-10-03drm/amdkfd: Fix NULL pointer dereference for set_scratch_backing_va()Yong Zhao1-1/+0
Currently this function pointer is missing for GFX10. Considering it is a void function since GFX9, fix it by checking the function pointer before dereferencing it.

2019-07-18drm/amdkfd: Implement kfd2kgd_calls for ArcturusOak Zeng1-0/+324
Arcturus shares most of the kfd2kgd_calls with gfx9. But due to SDMA register address change, it can't share SDMA related functions. Export gfx9 kfd2kgd_calls and implement SDMA related functions for Arcturus.
