From e2c719b75c8c186deb86570d8466df9e9eff919b Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Mon, 15 Dec 2014 13:56:32 -0500 Subject: [PATCH] drm/i915: tame the chattermouth (v2) Many distro's have mechanism in place to collect and automatically file bugs for failed WARN()s. And since i915 has a lot of hw state sanity checks which result in WARN(), it generates quite a lot of noise which is somewhat disconcerting to the end user. Separate out the internal hw-is-in-the-state-I-expected checks into I915_STATE_WARN()s and allow configuration via i915.verbose_checks module param about whether this will generate a full blown stacktrace or just DRM_ERROR(). The new moduleparam defaults to true, so by default there is no change in behavior. And even when disabled, you will still get an error message logged. v2: paint the macro names blue, clarify that the default behavior remains the same as before Signed-off-by: Rob Clark Acked-by: Jani Nikula Signed-off-by: Daniel Vetter --- Reading git-format-patch failed
