^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) Following a GPU hang the MSM driver outputs debugging information via
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) /sys/kernel/dri/X/show or via devcoredump (/sys/class/devcoredump/dcdX/data).

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) Each entry is in the form key: value. Sections headers will not have a value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) and all the contents of a section will be indented two spaces from the header.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) Each section might have multiple array entries the start of which is designated
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) by a (-).
