From ea1167d6601f370f5d7e425eb0b3c7577edd02cd Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 29 Mar 2011 13:19:09 +0100 Subject: [PATCH 1/2] drm/i915: Move the irq wait queue initialisation into the ring init Required so that we don't obliterate the queue if initialising the rings after the global IRQ handler is installed.
