I got the first CI results, and the logs are actually saved to disk in a place that feels right to me, the file igt_runner0.txt. This file contains the terminal output of igt-runner. Here is an example:

https://intel-gfx-ci.01.org/tree/intel-xe/IGTPW_12022/bat-dg2-oem2/igt_runner0.txt

We can clearly see that all tests are behaving properly and no change to the environment is undesired. So unless a review spot something that need change, the patch seems to be ready to be merged.
