[PATCH v2] drm/xe: Decouple xe_exec_queue and xe_lrc
Niranjana Vishwanathapura

Thu May 30 03:22:10 UTC 2024
Decouple xe_lrc from xe_exec_queue and reference count xe_lrc.
Removing hard coupling between xe_exec_queue and xe_lrc allows
flexible design where the user interface xe_exec_queue can be
destroyed independent of the hardware/firmware interface xe_lrc.
v2: Fix lrc indexing in wq_item_append()
