Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-6.16-rc1-2
with top-most commit 3d031d0d8daab86f9c3e9e89c80fec08367fb304
Merge branch 'pm-cpuidle'
on top of commit 9d230d500b0e5f7be863e2bf2386be5f80dd18aa
Merge tag 'driver-core-6.16-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core
to receive more power management updates for 6.16-rc1.
These revert an x86 commit that introduced a nasty power regression
on some systems, fix PSCI cpuidle driver and ACPI cpufreq driver
regressions, add Rust abstractions for cpufreq, OPP, clk, and
cpumasks, add a Rust-based cpufreq-dt driver, and do a minor
SCMI cpufreq driver cleanup:
- Revert an x86 commit that went into 6.15 and caused idle power,
including power in suspend-to-idle, to rise rather dramatically
on systems booting with "nosmt" in the kernel command line (Rafael
Wysocki).
- Prevent freeing an uninitialized pointer in the error path of
dt_idle_state_present() in the PSCI cpuidle driver (Dan Carpenter).
- Use KHz as the nominal_freq units in get_max_boost_ratio() in the
ACPI cpufreq driver (iGautham Shenoy).
- Add Rust abstractions for CPUFreq framework (Viresh Kumar).
- Add Rust abstractions for OPP framework (Viresh Kumar).
- Add basic Rust abstractions for Clk and Cpumask frameworks (Viresh
Kumar).
- Clean up the SCMI cpufreq driver somewhat (Mike Tipton).
Thanks!
