[RFC 0/5] drm/xe: Support capture and dump of devcoredump for general debug

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

It is useful to be able to dump driver/hardware state when various
unexpected errors occur. E.g. on an internal error in the GuC
communication layer, there is a dump of the GuC state. Currently the
CT code rolls its own capture and print. However, the devcoredump
mechanism is basically doing exactly the same thing. So tweak that to
allow it to be called from arbitrary places and use it instead.
