-----Original Message----- From: Intel-gfx intel-gfx-bounces@lists.freedesktop.org On Behalf Of Imre Deak Sent: Tuesday, 5 August 2025 10.37 To: intel-gfx@lists.freedesktop.org; intel-xe@lists.freedesktop.org Cc: stable@vger.kernel.org; Lin, Charlton charlton.lin@intel.com; Almahallawy, Khaled khaled.almahallawy@intel.com Subject: [PATCH 05/19] drm/i915/icl+/tc: Convert AUX powered WARN to a debug message
The BIOS can leave the AUX power well enabled on an output, even if this isn't required (on platforms where the AUX power is only needed for an AUX access). This was observed at least on PTL. To avoid the WARN which would be triggered by this during the HW readout, convert the WARN to a debug message.
