It contains: - A new files with init functions of usermode queues. - A queue context manager in driver private data. V1: Worked on design review comments from RFC patch series: (https://patchwork.freedesktop.org/series/112214/) - Alex: Keep a list of queues, instead of single queue per process. - Christian: Use the queue manager instead of global ptrs, Don't keep the queue structure in amdgpu_ctx V2: - Reformatted code, split the big patch into two V3: - Integration with doorbell manager V4: - Align the structure member names to the largest member's column (Luben) - Added SPDX license (Luben) V5: - Do not add amdgpu.h in amdgpu_userqueue.h (Christian). - Move struct amdgpu_userq_mgr into amdgpu_userqueue.h (Christian).
