Subject: Why idle_freq is set to RPn and not RPe
Date: Wed, 30 Dec 2015 14:51:27 +0530	[thread overview]
Message-ID: <5683A217.4000806@intel.com> (raw)

Hi Chris,

With below commit, idle frequency is made RPn (HW Min).
Why are we not keeping it at RPe (Efficient Frequency)?
My understanding was to set Rpe on idle so that when GPU is out of RC6 
it can start operating at efficient frequency.

     drm/i915: Relax RPS contraints to allows setting minfreq on idle


Thanks
Sagar
