This is a note to let you know that I've just added the patch titled drm/xe/devcoredump: Improve section headings and add tile info to the 6.12-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-xe-devcoredump-improve-section-headings-and-add-.patch and it can be found in the queue-6.12 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit cf1a7927f65ee9962e8de9edcc9059d5d1f5d006 Author: John Harrison <John.C.Harrison@xxxxxxxxx> Date: Wed Oct 2 17:46:03 2024 -0700 drm/xe/devcoredump: Improve section headings and add tile info [ Upstream commit c28fd6c358db44c87a1408f27ba412c94e25e6c2 ] The xe_guc_exec_queue_snapshot is not really a GuC internal thing and is definitely not a GuC CT thing. So give it its own section heading. The snapshot itself is really a capture of the submission backend's internal state. Although all it currently prints out is the submission contexts. So label it as 'Contexts'. If more general state is added later then it could be change to 'Submission backend' or some such. Further, everything from the GuC CT section onwards is GT specific but there was no indication of which GT it was related to (and that is impossible to work out from the other fields that are given). So add a GT section heading. Also include the tile id of the GT, because again significant information. Lastly, drop a couple of unnecessary line feeds within sections. v2: Add GT section heading, add tile id to device section.
