These update the CPPC cpufreq driver and intel_pstate (which involves updating the cpufreq core and the schedutil governor) and make janitorial changes in the ACPI code handling processor objects. Specifics: - Rework the passive-mode "fast switch" path in the intel_pstate driver to allow it receive the minimum (required) and target (desired) performance information from the schedutil governor so as to avoid running some workloads too fast (Rafael Wysocki). - Make the intel_pstate driver allow the policy max limit to be increased after the guaranteed performance value for the given CPU has increased (Rafael Wysocki). - Clean up the handling of CPU coordination types in the CPPC cpufreq driver and make it export frequency domains information to user space via sysfs (Ionela Voinescu). - Fix the ACPI code handling processor objects to use a correct coordination type when it fails to map frequency domains and drop a redundant CPU map initialization from it (Ionela Voinescu, Punit Agrawal). Thanks! --------------- Ionela Voinescu (5): ACPI: processor: fix NONE coordination for domain mapping failure cppc_cpufreq: use policy->cpu as driver of frequency setting cppc_cpufreq: clarify support for coordination types cppc_cpufreq: expose information on frequency domains cppc_cpufreq: replace per-cpu data array with a list Punit Agrawal (1): ACPI: processor: Drop duplicate setting of shared_cpu_map Rafael J. Wysocki (4): cpufreq: schedutil: Add util to struct sg_cpu cpufreq: Add special-purpose fast-switching callback for drivers cpufreq: intel_pstate: Implement the ->adjust_perf() callback cpufreq: intel_pstate: Use most recent guaranteed performance values --------------- Documentation/ABI/testing/sysfs-devices-system-cpu | 3 +- drivers/acpi/cppc_acpi.c | 141 ++++++-------- drivers/acpi/processor_perflib.c | 3 +- drivers/cpufreq/cppc_cpufreq.c | 204 ++++++++++++--------- drivers/cpufreq/cpufreq.c | 40 ++++ drivers/cpufreq/intel_pstate.c | 86 +++++++-- include/acpi/cppc_acpi.h | 6 +- include/linux/cpufreq.h | 14 ++ include/linux/sched/cpufreq.h | 5 + kernel/sched/cpufreq_schedutil.c | 106 ++++++++--- 10 files changed, 388 insertions(+), 220 deletions(-)
