Cover letter [PATCH v4 0/5] cpufreq: intel_pstate: Address some HWP-related oddities
Hi All,
The last two patches in the v3 needed to be updated to take re-enabling of HWP after an ACPI S3 suspend/resume cycle into account appropriately. The first three patches are the same as before.
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
