Use new pending job list iterator and new helper functions in Xe to avoid reaching into DRM scheduler internals. Part of this change involves removing pending jobs debug information from debugfs and devcoredump. As agreed, the pending job list should only be accessed when the scheduler is stopped. However, it's not straightforward to determine whether the scheduler is stopped from the shared debugfs/devcoredump code path. Additionally, the pending job list provides little useful information, as pending jobs can be inferred from seqnos and ring head/tail positions. Therefore, this debug information is being removed. v4: - Add comment around DRM_GPU_SCHED_STAT_NO_HANG (Niranjana) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Niranjana Vishwanathapura <niranjana.vishwanathapura@intel.com> Link: https://patch.msgid.link/20260110012739.2888434-3-matthew.brost@intel.com
