This is needed to avoid a race condition where the scheduler may still be processing messages for a queue that has been closed, which can lead to errors. This series includes a rebase of patch fe73d8e1cdfac drm/xe: Disable scheduling early on FD close to avoid CAT error cascade Daniel Charles (1): drm/xe: Synchronously wait for queue kill on FD close Matthew Brost (2): drm/xe: Read scheduler message opcode under lock drm/xe: Disable scheduling early on FD close to avoid CAT error cascade drivers/gpu/drm/xe/xe_device.c | 8 +- drivers/gpu/drm/xe/xe_exec_queue.c | 13 +++ drivers/gpu/drm/xe/xe_exec_queue.h | 1 + drivers/gpu/drm/xe/xe_exec_queue_types.h | 2 + drivers/gpu/drm/xe/xe_gpu_scheduler.c | 13 ++- drivers/gpu/drm/xe/xe_gpu_scheduler_types.h | 2 +- drivers/gpu/drm/xe/xe_guc_exec_queue_types.h | 2 +- drivers/gpu/drm/xe/xe_guc_submit.c | 85 ++++++++++++++++++-- 8 files changed, 112 insertions(+), 14 deletions(-) -- 2.43.0
