The purpose of this series is to address some peculiarities related to taking CPUs offline/online and switching between different operation modes with HWP enabled that have become visible after allowing the driver to work in the passive mode with HWP enabled in 5.9-rc1 (and one that was there earlier, but can be addressed easily after the changes made in 5.9-rc1). Please refer to the patch changelogs for details. For easier testing/review, the series is available from the git branch at: git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ intel_pstate-testing I've done my best to address all of the possible corner cases, but the test matrix is quite extensive and I may have missed something, so go ahead and test. Thanks, Rafael
