Date: Mon, 18 Mar 2013 14:08:44 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Stéphane Marchesin <marcheu@...omium.org>, Jesse Barnes <jbarnes@...tuousgeek.org>, Daniel Vetter <daniel.vetter@...ll.ch> Subject: [ 36/48] drm/i915: Increase the RC6p threshold. 3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stéphane Marchesin <marcheu@...omium.org> commit 0920a48719f1ceefc909387a64f97563848c7854 upstream. 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.
