drm/amdkfd: Expose HDP registers to user space

2019-05-24T17:20:47Z

Introduce a new memory type (KFD_IOC_ALLOC_MEM_FLAGS_MMIO_REMAP) and expose mmio page of HDP registers to user space through this new memory type. v2: moved remapped hdp regs to adev struct v3: rename the new memory type to ALLOC_MEM_FLAGS_MMIO_REMAP v4: use more generic function name v5: Fail remapped mmio allocation for asics before gfx9 Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: get_fw_version isn't ASIC specific

2019-04-19T16:32:40Z

Method of getting firmware version is the same across ASICs, so remove them from ASIC-specific files and create one in amdgpu_amdkfd.c. This new created get_fw_version simply reads fw_version from adev->gfx than parsing the ucode header. Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Optimize out sdma doorbell array in kgd2kfd_shared_resources

2019-02-18T23:00:50Z

We can directly calculate sdma doorbell indexes in the process doorbell pages through the doorbell_index structure in amdgpu_device, so no need to cache them in kgd2kfd_shared_resources any more. This alleviates the adaptation needs when new SDMA configurations are introduced. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Fix bugs regarding CP queue doorbell mask on SOC15

2019-02-18T23:00:41Z

Reserved doorbells for SDMA IH and VCN were not properly masked out when allocating doorbells for CP user queues. This patch fixed that. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Relocate kgd2kfd function declaration

2019-01-14T20:04:28Z

Since amdkfd is merged into amdgpu module and amdgpu can access amdkfd directly, move declaration of kgd2kfd functions from kfd_priv.h to amdgpu_amdkfd.h Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdkfd: Add support for doorbell BOs

2018-12-07T23:14:00Z

This allows user mode to map doorbell pages into GPUVM address space. That way GPUs can submit to user mode queues (self-dispatch). Acked-by: Alex Deucher Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher
