Hi Dave, Sima, Here comes the main pull request for 6.15. New sysfs UAPI for configuring the GuC power profiles is probably the most interesting addition. Other than that, there is one performance workaround for Gen12 platforms and a bunch of fixes, mostly around the GuC code. PMU code was consolidated to use kernel facility for CPU hotplug handling which required a merge during the development window. Other than those just a collection of cleanups and selftest fixes.
