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

drm/amdgpu: Workaround build failure due to trace conflict

2018-12-07T22:53:47Z

Avoid including mmu_context.h in amdgpu_amdkfd.h since that may be included in other header files that define traces. This leads to conflicts due to traces defined in other headers included via mmu_context.h. Acked-by: Alex Deucher Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Add proper prefix to functions

drm/amd: Interface change to support 64 bit page_table_base

2018-09-27T02:09:17Z

amdgpu_gpuvm_get_process_page_dir should return the page table address in the format expected by the pm4_map_process packet for all ASIC generations. Signed-off-by: Shaoyun Liu Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher Signed-off-by: Felix Kuehling Acked-by: Alex Deucher

drm/amdkfd: Change the control stack MTYPE from UC to NC on GFX9

2018-09-20T15:25:17Z

CWSR fails on Raven if the control stack is MTYPE_UC, which is used for regular GART mappings. As a workaround we map it using MTYPE_NC. The MEC firmware expects the control stack at one page offset from the start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU added a memory allocation flag just for this purpose.

drm/amdkfd: Release an acquired process vm

2018-08-29T17:35:00Z

For compute vm acquired from amdgpu, vm.pasid is managed by kfd. Decouple pasid from such vm on process destroy to avoid duplicate pasid release. Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Set pasid for compute vm (v2)

2018-08-29T17:34:49Z

To make a amdgpu vm to a compute vm, the old pasid will be freed and replaced with a pasid managed by kfd. Kfd can't reuse original pasid allocated by amdgpu because kfd uses different pasid policy with amdgpu. For example, all graphic devices share one same pasid in a process. v2: rebase (Alex) Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher
