On fi-icl-dsi HW changes BIOS/Silicon now updated to D1/Q3R5.
The CI Bug Log issue associated to this bug has been updated. ### New filters associated * fi-icl-dsi: igt@i915_pm_rpm@i2c - dmesg-warn - Missing case (dig_port->aux_ch == 1) - https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_337/fi-icl-dsi/igt@i915_pm_rpm@i2c.html
The problem is <7>[ 10.069905] [drm:intel_bios_port_aux_ch [i915]] using AUX B for port C (VBT) which is impossible. Port C is a TypeC port and can only be connected to an AUX starting from AUX C (and the AUX depending on the corresponding DP-Alt/TBT power well). In addition either the rework for legacy-DP functionality is missing from the RVP or the BIOS setup is not configured accordingly. So this is again a VBT issue wrt. the port C information in it. Please assign to someone who could generate a new VBT, removing the port C info from there completely, or fixing the AUX info in it (if the fi-icl-dsi has indeed the required DP rework).
