From 2fa60f6d515b509b05f6a96afc83ac9629d6401b Mon Sep 17 00:00:00 2001 From: Mika Kuoppala Date: Tue, 7 Oct 2014 17:21:27 +0300 Subject: [PATCH] drm/i915: Check workaround status on dfs read time As the workaround list has the value as initialization time constant, we can do the simple checking on the go without negleting igt.
