[Intel-xe] [PATCH 0/4] RFC: Add new device configuration infrastructure to

[Stuart Summers]

This is attempting to take the best parts of i915 module parameters
(minus the actual module parameters) and add to xe to allow for better
debuggability and configuration in order to help isolate problems
on a per-device level instead of global module parameters.

Note that I did review a few options here: configfs (not generally
used by the drm stack), module parameters (we have some negative
history here), sysfs (not the right approach given the focus on
user interface here). Debugfs is used in various drm drivers to
configure various device characteristics. The infrastructure being
presented here has at a high level been present in the i915 driver
for some years now, so provides a good starting point for quick
debug additions without exposing users to some of the challenges
faced with module parameters in the past.

Stuart Summers (4):
  drm/xe: Refactor early device init
  drm/xe: Refactor debugfs into an early and late part
  drm/xe: Add new device configuration debugfs infrastructure
  drm/xe: Migrate module parameters to new debugfs structure
