drm/amdgpu: Add kfd2kgd interface to acquire an existing VM

2018-03-15T21:27:43Z

This allows acquiring an existing VM from a render node FD to use it for a compute process. Such VMs get destroyed when the original file descriptor is released. Added a callback from amdgpu_vm_fini to handle KFD VM destruction correctly in this case. v2: * Removed vm->vm_context check in amdgpu_amdkfd_gpuvm_destroy_cb, check vm->process_info earlier instead Signed-off-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Oded Gabbay

drm/amdgpu: Fix initial validation of PD BO for KFD VMs

2018-03-15T21:27:41Z

Make sure the PD BO is valid and attach the eviction fence during VM creation. This ensures that the pd_phys_address is actually valid and an eviction that would invalidate it triggers a KFD process eviction like it should. v2: Use uninterruptible waiting in initial PD validation Signed-off-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Oded Gabbay

drm/amdgpu: Move KFD-specific fields into struct amdgpu_vm

2018-03-15T21:27:40Z

Remove struct amdkfd_vm and move the fields into struct amdgpu_vm. This will allow turning a VM created by a DRM render node into a KFD VM. v2: Removed vm_context field Signed-off-by: Felix Kuehling Reviewed-by: Christian König Signed-off-by: Oded Gabbay

drm/amdgpu: explicit give BO type to amdgpu_bo_create

2018-03-14T20:08:24Z

Drop the "kernel" and sg parameter and give the BO type to create explicit to amdgpu_bo_create instead of figuring it out from the parameters. Signed-off-by: Christian König Reviewed-by: Roger He Signed-off-by: Alex Deucher

drm/amdgpu: Add GPUVM memory management functions for KFD

2018-02-07T01:32:38Z

v2: * Removed unused flags from struct kgd_mem * Updated some comments * Added a check to unmap_memory_from_gpu whether BO was mapped v3: add mutex_destroy in relevant places Signed-off-by: Felix Kuehling Acked-by: Oded Gabbay Signed-off-by: Oded Gabbay
