[igt-dev] [RFC 0/2] lib/xe_gpu: Introduce xe_gpu library

[Anna Karas]

OPENS:
1. Lack of wedged concept in XE: @Matthew informed me that there is no
intent to have reporting wedged device in XE. However, @Joonas believes
that it may be useful - "it's used at least in specific diagnostics and
hardware repair flows for PVC and FLR for all platforms, where we
prevent further accesses to the hardware. So an alternative mechanism is
needed for those". Since xe_require_gpu() is a direct port of i915's 
igt_require_gem() stripped of wedged device reporting, this could be a
good opportunity to discuss this.

2. igt_require_gem() was also responsible for restoring reset and
enable_hangcheck modparams. Do we need those parameters here? Do/will we
need different ones do restore?

3. Would you find adding equivalent of gem_quiescent_gpu here worth?
