Subject: [PATCH] drm/i915: Increase the RC6p threshold.
Date: Tue, 29 Jan 2013 19:41:59 -0800 [thread overview]
Message-ID: <1359517319-30687-1-git-send-email-marcheu@chromium.org> (raw)
This increases GEN6_RC6p_THRESHOLD from 100000 to 150000. For some
reason this avoids the gen6_gt_check_fifodbg.isra warnings and
associated GPU lockups, which makes my ivy bridge machine stable.
