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/amdkfd: Simplify kfd2kgd interface

2018-11-05T19:21:07Z

After amdkfd module is merged into amdgpu, KFD can call amdgpu directly and no longer needs to use the function pointer. Replace those function pointers with functions if they are not ASIC dependent.

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

drm/amdkfd: Fix error codes in kfd_get_process

2018-07-12T02:32:47Z

Return ERR_PTR(-EINVAL) if kfd_get_process fails to find the process. This fixes kernel oopses when a child process calls KFD ioctls with a file descriptor inherited from the parent process.

drm/amdkfd: Implement doorbell allocation for SOC15

2018-04-10T21:33:05Z

Allocate doorbells according to the doorbell routing information on SOC15 ASICs (Vega10 and later). On older ASICs we continue to use the queue_id as the doorbell ID to maintain compatibility with the Thunk.

drm/amdkfd: Clean up KFD_MMAP_ offset handling

2018-04-10T21:33:04Z

Use bit-rotate for better clarity and remove _MASK from the #defines as these represent mmap types. Centralize all the parsing of the mmap offset in kfd_mmap and add device parameter to doorbell and reserved_mem map functions. Encode gpu_id into upper bits of vm_pgoff. This frees up the lower bits for encoding the the doorbell ID on Vega10. Signed-off-by: Harish Kasiviswanathan Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Add quiesce_mm and resume_mm to kgd2kfd_calls

2018-03-23T19:32:32Z

These interfaces allow KGD to stop and resume all GPU user mode queue access to a process address space. This is needed for handling MMU notifiers of userptrs mapped for GPU access in KFD VMs. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Use ordered workqueue to restore processes

2018-03-23T19:30:36Z

Restoring multiple processes concurrently can lead to live-locks where each process prevents the other from validating all its BOs. v2: fix duplicate check of same variable Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Add TC flush on VMID deallocation for Hawaii

2018-03-15T21:27:50Z

On GFX7 the CP does not perform a TC flush when queues are unmapped. To avoid TC eviction from accessing an invalid VMID, flush it explicitly before releasing a VMID. v2: Fix unnecessary list_for_each_entry_safe v3: Moved allocation to kfd_process_device_init_vm Signed-off-by: Amber Lin Signed-off-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Oded Gabbay
