Chris Wilson 48572edd9d drm/i915: Disable the mmio.debug WARN after it fires ... If we have a single unclaimed register, we will have lots. A WARN for each one makes the machine unusable and does not aid debugging. Convert the i915.mmio_debug option to a counter for how many WARNs to fire before shutting up. Even when i915.mmio_debug was disabled it would continue to shout an *ERROR* for every interrupt, without any information at all for debugging. The massive verbiage was added in commit 5978118c39 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Wed Jul 16 17:49:29 2014 -0300 drm/i915: reorganize the unclaimed register detection code v2: Automatically enable invalid mmio reporting for the *next* invalid access if mmio_debug is disabled by default. This should give us clearer debug information without polluting the logs too much. v3: Compile fixes, rebase.
