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-diff-tree failed
