[PATCH v2 0/9] KFD user queue validation

[Philip Yang <Philip.Yang@amd.com>]

This patch series do additional queue buffers validation in the queue
creation IOCTLS, fail the queue creation if buffers not mapped on the GPU
with the expected size.

Ensure queue buffers residency by tracking the GPUVM virtual addresses
for queue buffers to return error if the user tries to free and unmap them
when the qeueu is active, or evict the queue if SVM memory is unmapped and
freed from CPU.

Patch 1-2 is prepration work and general fix.

v2:
 - patch 3/9, keep wptr_bo_gart in struct queue

Philip Yang (9):
  drm/amdkfd: kfd_bo_mapped_dev support partition
  drm/amdkfd: amdkfd_free_gtt_mem clear the correct pointer
  drm/amdkfd: Refactor queue wptr_bo GART mapping
  drm/amdkfd: Validate user queue buffers
  drm/amdkfd: Ensure user queue buffers residency
  drm/amdkfd: Validate user queue svm memory residency
  drm/amdkfd: Validate user queue update
  drm/amdkfd: Store queue cwsr area size to node properties
  drm/amdkfd: Validate queue cwsr area and eop buffer size
