From df662a28c2c099a8ea1aa7cb4334d9df8aba6f95 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 4 Aug 2014 11:17:25 +0200 Subject: [PATCH] drm/i915: Tune down MCH_SSKPD values warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Users often can't do anything about this since their vendors stopped providing BIOS updates. Also we seem to be able to hack around it with increased latency values, and thus far the only reports have been for screens with really high resolutions. So tune it down to a level where only developers can see it. Also drop some of the end-user fluff.
