From 0920a48719f1ceefc909387a64f97563848c7854 Mon Sep 17 00:00:00 2001 From: Stéphane Marchesin Date: Tue, 29 Jan 2013 19:41:59 -0800 Subject: drm/i915: Increase the RC6p threshold. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
