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
