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: Use sdma_engine array

2019-01-14T20:04:30Z

Use sdma_engine[8] array instead of sdma_engine0~7 so it is easier to program. Signed-off-by: Oak Zeng Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Remove kgd2kfd function pointers

2019-01-14T20:04:29Z

drm/amdgpu: Simplify kgd2kfd interface

2019-01-14T20:04:29Z

After amdkfd is merged into amdgpu module, amdgpu can call amdkfd functions directly. Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Acked-by: Christian König 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

This function was renamed in a previous commit. Update the stub function name for builds with CONFIG_HSA_AMD disabled. Fixes: 611736d8447c ("drm/amdgpu: Add KFD VRAM limit checking") Acked-by: Andrey Grodzovsky Acked-by: Christian König Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Add DMABuf import functionality

2018-12-07T23:13:54Z

This is used for interoperability between ROCm compute and graphics APIs. It allows importing graphics driver BOs into the ROCm SVM address space for zero-copy GPU access. The API is split into two steps (query and import) to allow user mode to manage the virtual address space allocation for the imported buffer.

drm/amdgpu: Add KFD VRAM limit checking

2018-12-07T23:13:15Z

We don't want KFD processes evicting each other over VRAM usage. Therefore prevent overcommitting VRAM among KFD applications with a per-GPU limit. Also leave enough room for page tables on top of the application memory usage. Acked-by: Alex Deucher Signed-off-by: Felix Kuehling Reviewed-by: Eric Huang Signed-off-by: Alex Deucher
