    drm/i915: tame the chattermouth (v2) · e2c719b7
    Rob Clark authored
    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
