Subject: [PATCH] drm/i915: make default minimum frequency RP1 instead of RPN
Date: Fri, 26 Oct 2012 10:17:39 -0700 [thread overview]
Message-ID: <1351271859-5170-1-git-send-email-jbarnes@virtuousgeek.org> (raw)
We should only ever go below RP1 for thermal reasons. Users can still
control this through sysfs by manually reducing the minimum frequency
(and max if they want to clamp their frequency for power reasons, e.g.
to keep fans off or something).
