From 2f04c0d24c245cb9996b2557f59fe9cafd3762b7 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 5 Jan 2012 01:05:26 +0100 Subject: [PATCH] drm/i915: rip out the HWSTAM missed irq workaround With the new ducttape of much finer quality, this seems to be no longer necessary. Tested on my ivb and snb machine with the usual suspects of testcases.
