From e959b5db4aacc27bcf92889e658445326ebc4bfb Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 22 Dec 2011 14:55:01 -0800 Subject: [PATCH] drm/i915: Make the fallback IRQ wait not sleep. The waits we do here are generally so short that sleeping is a bad idea unless we have an IRQ to wake us up. Improves regression test performance from 18 minutes to 3.5 minutes on gen7, which is now consistent with the previous generation.
