All of these "promotion" patches are tested by using 
amd-staging-drm-next. In a few words:

1. We get the latest code from amd-staging-drm-next;
2. We apply these weekly promotion patches on top of it;
3. We compile, run unit tests, and run many manual tests (Daniel does that).

If everything is alright with Daniel's tests, we feel confident to merge 
these series on top amd-staging-drm-next (we are basically trying to 
avoid regressions here).

Anyway, maybe we can rephrase:

  Tested on Ubuntu 22.04 with Kernel Version 5.16, and ChromeOS

to

  Tested on Ubuntu 22.04 and ChromeOS with amd-staging-drm-next + 
promotion patches.

We run IGT tests, some scripts that validate some specific areas, and 
Daniel has an extensive set of manual tests.
