I've looked at the logs a bit more. Here's a patch adding some more debug information. Would you please apply this to your 3.10 kernel and generate a log file the same way as you did before. The driver will be even more chatty - but I don't expect any problems from this.
I applied this patch (but not the one you sent on Monday), recompiled and logged:diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index e43d809..46bb77c 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -919,6 +919,11 @@ static inline void intel_hpd_irq_handler(struct drm_device *dev, spin_lock(&dev_priv->irq_lock); for (i = 1; i < HPD_NUM_PINS; i++) { + if (IS_G4X(dev) && (hpd[i] & hotplug_trigger) && + dev_priv->hpd_stats[i].hpd_mark != HPD_ENABLED) + DRM_DEBUG_KMS("Received HPD intterupt although disabled\n", + I915_READ(PORT_HOTPLUG_EN)); + if (!(hpd[i] & hotplug_trigger) || dev_priv->hpd_stats[i].hpd_mark != HPD_ENABLED) continue; @@ -929,6 +934,8 @@ static inline void intel_hpd_irq_handler(struct drm_device *dev, + msecs_to_jiffies(HPD_STORM_DETECT_PERIOD))) { dev_priv->hpd_stats[i].hpd_last_jiffies = jiffies; dev_priv->hpd_stats[i].hpd_cnt = 0;+ DRM_DEBUG_KMS("Received HPD interrupt on PIN %d - jiffies: %d\n", i,+ dev_priv->hpd_stats[i].hpd_last_jiffies); } else if (dev_priv->hpd_stats[i].hpd_cnt > HPD_STORM_THRESHOLD) { dev_priv->hpd_stats[i].hpd_mark = HPD_MARK_DISABLED; dev_priv->hpd_event_bits &= ~(1 << i); @@ -936,6 +943,8 @@ static inline void intel_hpd_irq_handler(struct drm_device *dev, storm_detected = true; } else { dev_priv->hpd_stats[i].hpd_cnt++; + DRM_DEBUG_KMS("Received HPD interrupt on PIN %d - cnt: %d\n", i, + dev_priv->hpd_stats[i].hpd_cnt); } }
