Hi Jesse, Do you mean increase /sys/class/drm/card0/power/rc6p_residency_ms from 100000 to 150000, and measure power difference on IVB when system is on idle? -----Original Message----- From: Jesse Barnes [mailto:jbarnes at virtuousgeek.org] Sent: Wednesday, February 20, 2013 8:16 AM To: St?phane Marchesin Cc: intel-gfx at lists.freedesktop.org; Zhang, Ouping Subject: Re: [PATCH] drm/i915: Increase the RC6p threshold.

Ouping, can you measure any power difference between the two values? Thanks, -- Jesse Barnes, Intel Open Source Technology Center
