[Intel-gfx] [RFC 0/2] slice shutdown debugfs interface for Gen8/Gen9

[Dmitry Rogozhkin]

Starting from Gen8 HW supports dynamic power on/off slices. This
permits to free power budget and may dramatically affect performance.
This patch series suggests an interface (debugfs) to permit user to
setup number of active slices. Interface can be used in performance
investigations targeting scalability across hw platforms.

  drm/i915/skl: add slice shutdown debugfs interface
  drm/i915/bdw: permit make_rpcs execution on BDW to enable slice
    shutdown
