Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-6.4-rc3
with top-most commit 5783ecc90e24a870a563b1acbfd13cad3786e519
Merge branch 'pm-tools'
on top of commit f1fcbaa18b28dec10281551dfe6ed3a3ed80e3d6
Linux 6.4-rc2
to receive power management fixes for 6.4-rc3.
These fix two issues in the cpupower utility and get rid of a spurious warning message printed to the kernel log by the ACPI cpufreq driver after recent changes.
Specifics:
- Get rid of a warning message printed by the ACPI cpufreq driver after recent changes in it when anohter CPU performance scaling driver is registered already when it starts (Petr Pavlu).
- Make cpupower read TSC on each CPU right before reading MPERF so as to reduce the potential time difference between the TSC and MPERF accesses and improve the C0 percentage calculation (Wyes Karny).
- Fix a possible file handle leak and clean up the code in the sysfs_get_enabled() function in cpupower (Hao Zeng).
Thanks!
