The patches need to be squashed to be bisectable though. For example, patch #2 changes the MTK job names and adds more jobs, but the corresponding xfail updates only come in #7 and #8. This means we have a span of a few patches where we don't have useful test results. A better sequencing would be something like: 1. add ANX7625 config 2. refactor _existing_ MTK display jobs to use YAML includes, change the existing job name, and rename the existing xfail set, remove IGT_FORCE_DRIVER from the script since it's now set by the job 3. add MTK Panfrost+PVR GPU jobs with new xfails, add xfail entry to MAINTAINERS 4+5: same as 2+3 but for Amlogic 6+7: same as 2+3 but for Rockchip Then the separate rename/update xfail commits just disappear, as does the removal of IGT_FORCE_DRIVER, because it's just done incrementally as part of the commits which change the related functionality. It's extremely important that every change can work standalone, instead of introducing intermediate breakage which is only fixed in later commits in the series. Cheers, Daniel
