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 drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c | 14 +- drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h | 6 +- .../gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 24 +- drivers/gpu/drm/amd/amdgpu/amdgpu_object.h | 6 + drivers/gpu/drm/amd/amdkfd/kfd_chardev.c | 61 +--- drivers/gpu/drm/amd/amdkfd/kfd_device.c | 4 +- .../drm/amd/amdkfd/kfd_device_queue_manager.c | 8 +- drivers/gpu/drm/amd/amdkfd/kfd_mqd_manager.c | 2 +- drivers/gpu/drm/amd/amdkfd/kfd_priv.h | 19 +- drivers/gpu/drm/amd/amdkfd/kfd_process.c | 2 +- .../amd/amdkfd/kfd_process_queue_manager.c | 79 +++- drivers/gpu/drm/amd/amdkfd/kfd_queue.c | 336 ++++++++++++++++++ drivers/gpu/drm/amd/amdkfd/kfd_svm.c | 12 + drivers/gpu/drm/amd/amdkfd/kfd_svm.h | 1 + drivers/gpu/drm/amd/amdkfd/kfd_topology.c | 2 + drivers/gpu/drm/amd/amdkfd/kfd_topology.h | 4 + 16 files changed, 489 insertions(+), 91 deletions(-) -- 2.43.2
