drm/amdkfd: Delete unnecessary pr_fmt switch

2019-10-30T15:06:51+00:00

Given amdkfd.ko has been merged into amdgpu.ko, this switch is no
longer useful.

drm/amdkfd: Use array to probe kfd2kgd_calls

2019-10-03T14:11:05+00:00

This is the same idea as the kfd device info probe and move all the
probe control together for easy maintenance.

drm/amdkfd: Eliminate get_atc_vmid_pasid_mapping_valid

2019-10-03T14:11:04+00:00

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.

drm/amdkfd: Use better name for sdma queue non HWS path

2019-10-03T14:11:03+00:00

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.

drm/amdkfd: Delete useless SDMA register setting on non HWS path

2019-10-03T14:11:03+00:00

HW folks have confirm that we should not touch RESUME_CTX of
SDMA*_GFX_CONTEXT_CNTL when manipulating RLC queues.

drm/amdkfd: Fix NULL pointer dereference for set_scratch_backing_va()

2019-10-03T14:11:01+00:00

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.

drm/amdkfd: Implement kfd2kgd_calls for Arcturus

2019-07-18T19:18:04+00:00

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.
