From 61a05870b939b9c5551817ad65b74194ea84140c Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 7 Oct 2016 07:53:26 +0100 Subject: drm/i915: Reset the breadcrumbs IRQ more carefully Along with the interrupt, we want to restore the fake-irq and wait-timeout detection. If we use the breadcrumbs interface to setup the interrupt as it wants, the auxiliary timers will also be restored. v2: Cancel both timers as well, sanitize the IMR.
