Subject: [PATCH] drm/i915: don't prevent CPU idle states
Date: Sat,  8 Dec 2012 13:48:13 +0100	[thread overview]
Message-ID: <1354970893-17950-1-git-send-email-tomi@nomi.cz> (raw)

Commit 9ee32fea5f unconditionally prevents the CPU from entering idle states
until intel_dp_aux_ch completes for the first time, which never happens on my
DisplayPort-less intel gfx, causing the CPU to get rather hot.
