From 2837ac40698d0931727b957a40c8c8ea27c3bcb2 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 19 Nov 2014 16:25:38 +0200 Subject: [PATCH] drm/i915: vlv: increase timeout when setting idle GPU freq MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I saw punit timeouts in vlv_set_rps_idle() while running various subtests of pm_rpm. Increasing the timeout to 100ms got rid of the issue.
