[PATCH v2 0/5] reg_sr/whitelist fixes and refactors

[Lucas De Marchi]

First patch is an important fix that we could eventually trip on (and it
did in this series because it increases the amount of save-restore
registers).

Stop writing the unused NONPRIV registers and use the HWE save-restore
so it doesn't need a separate mmio application and handling for GuC.

v2:
  - Fix "Fixes" trailer in first commit
  - Replace xe_gt_dbg() with a previous patch by Michal Wajdeczko
  - Replace patch that was making all registers to be written with one
    that make sure that non-used slots are not written
  - Simplify last patch now that unused slots are not written

Lucas De Marchi (4):
  drm/xe/reg_sr: Remove register pool
  drm/xe/reg_sr: Convert whitelist to gt logging
  drm/xe/reg_sr: Stop setting all whitelist slots
  drm/xe: Apply whitelist to engine save-restore

Michal Wajdeczko (1):
  drm/xe: Introduce xe_gt_dbg_printer()
