[PATCH 00/14] Introduce xe_devcoredump.

[Rodrigo Vivi]

Xe needs to align with other drivers on the way that the error states are
dumped, avoiding a Xe only error_state solution. The goal is to use devcoredump
infrastructure to report error states, since it produces a standardized way
by exposing a virtual and temporary /sys/class/devcoredump device.

The initial goal is to have the simple_error_state in the devcoredump
so we start using the infrastructure.

But this is just a start point to start building a useful and
organized crash dump, using standard infrastructure. Later this
will be changed to have output that can be parsed by tools and
used for error replay.

Later, when we are in-tree, the goal is to collaborate with devcoredump
infrastructure with overall possible improvements, like multiple file support
for better organization of the dumps, snapshot support, dmesg extra print,
and whatever may make sense and help the overall infrastructure.
