[PATCH v5 0/6] power: uncore power improvements and auto-detection

Wed Aug 12 11:49:50 CEST 2026


- Fix uncore deinitialization for non-legacy modes.
- Enable power QoS for all modes (not just legacy).
- Fix uncore help text and log messages.
- Relocate uncore initialization from arg parsing to init_power_library().
- Support automatic probing of uncore drivers in AUTO_DETECT and delete
  useless code for auto-detection uncore environment.

Note:
There are still some power state rollback issues that haven't been
addressed, but they were originally present and are relatively trivial to
implement. These rollbacks will be handled after this patchset.
