During capture time, the target job may be unavailable (e.g., if it's in LR mode). However, the associated exec queue will be available regardless, change xe_engine_snapshot_capture_for_job to take a queue argument ann rename to xe_engine_snapshot_capture_for_queue. v2: - Reword commit message (Jonathan) - Remove redundant queueu check (Zhanjun) - Remove devcoredump job member (Zhanjun) Cc: Zhanjun Dong <zhanjun.dong@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241114022522.1951351-7-matthew.brost@intel.com
