> With GuC based SLPC, frequency control will be moved to GuC and Host will
> continue to control RC6 and Ring frequency setup. This needs separate
> handling of RPS, RC6 and ring frequencies in i915 flows. We still
> continue use the *gt_powersave routines with separate status variables
> for RPS, RC6, ring frequency as pm.rps.enabled, pm.rc6.enabled and
> pm.ring_pstate.configured respectively in dev_priv.
> Post this, with SLPC changes integrated we can just skip the Host RPS path
> in i915 PM flows.

This series is looking really good. An important first step in
separating rps from rc6.
