Subject: [PATCH 0/2] drm/i915/gmbus: Try to fix AUX software timeouts
Date: Tue, 21 Apr 2026 00:48:41 +0300 [thread overview]
Message-ID: <20260420214843.17514-1-ville.syrjala@linux.intel.com> (raw)
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Looks like the "AUX did not complete or timeout within 10ms" errors
in CI (currently visible on shard-dg1) are caused by GMBUS and AUX
fighting over the same hardware resources. Try to fix that by making
them take turns.
Ville Syrjälä (2):
drm/i915/gmbus: Lock AUX CH during GMBUS transfers
drm/i915/gmbus: Swap locks vs. wakeref in intel_gmbus_output_aksv()
