Contribution description

The Xmega have a Power Management implementation. This moves that code to AVR-8 common and enable Power Management for all variants.

Testing procedure

This was tested using examples/thread_duel and tests/periph/pm examples on atxmega-a1u-xpro and atmega328p-xplained-mini boards. It may requires more tests and any help is welcome.

Issues/PRs references

This is a preparation for future scheduling and IRQ optimizations.

I have impression that Murdock is randomly failing.

maribu commented Jul 5, 2023

The order in which app+board pairs are build is pretty random and the CI run stops once the first failure is hit. This could indeed result in pretty random failures, if more than on app fails.

The lasted failure (different modules used when building with TEST_KCONFIG=1 and without) could be fixed e.g. using

Building application "suit_update" for "native" with MCU "native".

is indeed a race condition in the build system that is triggered when compiling that app for native with -j :/ I can (occasionally) reproduce that one locally. I was hoping that @kaspar030 would take a look 😇

After a quick look things seem OK, maybe some logic issues for your consideration. I will try to test tomorrow when I am in the office. (I need to also familiarize myself with the whole PM stuff).
