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.
