dmesg output with 2 DP monitors connected to MST hub, Kernel Ver-4.16 from 2018
Q1 Intel grahics stack recipe

Once again, I am attaching the “dmesg” output taken with “drm.debug=0xe” &
“log-buf-len=2M” parameters in the kernel command line.

Also attached log contains all information of command “dmesg” starting from
kernel bootline. Also I have built the kernel & related graphics stack
referring the guidelines listed at
https://01.org/linuxgraphics/documentation/build-guide-0
 &  latest packages available at
https://01.org/linuxgraphics/downloads/2018q1-intel-graphics-stack-recipe.
