drm/amdgpu: Simplify eviction fence handling

2019-02-13T22:50:54Z

Temporarily removing eviction fences to avoid triggering them by accident is no longer necessary due to the fence_owner logic in amdgpu_sync_resv. As a result the ef_list usage of amdgpu_amdkfd_remove_eviction_fence and amdgpu_amdkfd_add_eviction_fence are no longer needed.

drm/amdgpu: Replace ttm_bo_wait with amdgpu_bo_sync_wait

2019-02-13T22:50:39Z

The fence_owner logic in amdgpu_sync_wait will allow waiting without having to temporarily remove eviction fences. Signed-off-by: Felix Kuehling Reviewed-by: Christian König Signed-off-by: Alex Deucher

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

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

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/ttm: allow reserving more than one shared slot v3

drm/amdkfd: change system memory overcommit limit

2018-11-20T19:01:54Z

It is to improve system limit by: 1. replacing userptrlimit with a total memory limit that conunts TTM memory usage and userptr usage. 2. counting acc size for all BOs. Signed-off-by: Eric Huang Reviewed-by: Felix Kuehling Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Fix KFD doorbell SG BO mapping

2018-11-20T19:01:12Z

This change prepares for adding SG BOs that will be used for mapping doorbells into GPUVM address space. This type of BO would be mistaken for an invalid userptr BO. Improve that check to test that it's actually a userptr BO so that SG BOs that are still in the CPU domain can be validated and mapped correctly.
