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 --- drivers/gpu/drm/i915/i915_drv.h | 30 ++++++++ drivers/gpu/drm/i915/i915_params.c | 5 ++ drivers/gpu/drm/i915/intel_display.c | 134 +++++++++++++++++------------------ drivers/gpu/drm/i915/intel_dp.c | 4 +- 4 files changed, 104 insertions(+), 69 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 24cc36a9f3ff..8e1ee6d56d6a 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -60,6 +60,35 @@ #undef WARN_ON #define WARN_ON(x) WARN(x, "WARN_ON(" #x ")") +/* Use I915_STATE_WARN(x) and I915_STATE_WARN_ON() (rather than WARN() and + * WARN_ON()) for hw state sanity checks to check for unexpected conditions + * which may not necessarily be a user visible problem.
