git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull thermal control updates from Rafael Wysocki: "As far as new functionality is concerned, there is a new thermal driver for the Intel Hardware Feedback Interface (HFI) along with some intel-speed-select utility changes to support it. There are also new DT compatible strings for a couple of platforms, and thermal zones on some platforms will be registered as HWmon sensors now. Apart from the above, some drivers are updated (fixes mostly) and there is a new piece of documentation for the Intel DPTF (Dynamic Power and Thermal Framework) sysfs interface. Specifics: - Add a new thermal driver for the Intel Hardware Feedback Interface (HFI) including the HFI initialization, HFI notification interrupt handling and sending CPU capabilities change messages to user space via the thermal netlink interface (Ricardo Neri, Srinivas Pandruvada, Nathan Chancellor, Randy Dunlap). - Extend the intel-speed-select utility to handle out-of-band CPU configuration changes and add support for the CPU capabilities change messages sent over the thermal netlink interface by the new HFI thermal driver to it (Srinivas Pandruvada). - Convert the DT bindings to yaml format for the Exynos platform and fix and update the MAINTAINERS file for this driver (Krzysztof Kozlowski). - Register the thermal zones as HWmon sensors for the QCom's Tsens driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour). - Add the msm8953 compatible documentation in the bindings (Luca Weiss). - Add the sm8150 platform support to the QCom LMh driver's DT binding (Thara Gopinath). - Check the command result from the IPC command to the BPMP in the Tegra driver (Mikko Perttunen). - Silence the error for normal configuration where the interrupt is optionnal in the Broadcom thermal driver (Florian Fainelli). - Remove remaining dead code from the TI thermal driver (Yue Haibing). - Don't use bitmap_weight() in end_power_clamp() in the powerclamp driver (Yury Norov). - Update the OS policy capabilities handshake in the int340x thermal driver (Srinivas Pandruvada). - Increase the policies bitmap size in int340x (Srinivas Pandruvada). - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the int340x thermal driver (Rafael Wysocki). - Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang). - Add Intel Dynamic Power and Thermal Framework (DPTF) kernel interface documentation (Srinivas Pandruvada). - Fix bullet list warning in the thermal documentation (Randy Dunlap)" * tag 'thermal-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (30 commits) thermal: int340x: Update OS policy capability handshake thermal: int340x: Increase bitmap size Documentation: thermal: DPTF Documentation MAINTAINERS: thermal: samsung: update Krzysztof Kozlowski's email thermal/drivers/ti-soc-thermal: Remove unused function ti_thermal_get_temp() thermal/drivers/brcmstb_thermal: Interrupt is optional thermal: tegra-bpmp: Handle errors in BPMP response drivers/thermal/ti-soc-thermal: Add hwmon support dt-bindings: thermal: tsens: Add msm8953 compatible dt-bindings: thermal: Add sm8150 compatible string for LMh thermal/drivers/qcom/lmh: Add support for sm8150 thermal/drivers/tsens: register thermal zones as hwmon sensors MAINTAINERS: thermal: samsung: Drop obsolete properties dt-bindings: thermal: samsung: Convert to dtschema tools/power/x86/intel-speed-select: v1.12 release tools/power/x86/intel-speed-select: HFI support tools/power/x86/intel-speed-select: OOB daemon mode thermal: intel: hfi: INTEL_HFI_THERMAL depends on NET thermal: netlink: Fix parameter type of thermal_genl_cpu_capability_event() stub thermal: Replace acpi_bus_get_device() ...

2022-02-22cpupower: Enable boost state support for AMD P-State moduleHuang Rui3-0/+25
The legacy ACPI hardware P-States function has 3 P-States on ACPI table, the CPU frequency only can be switched between the 3 P-States. While the processor supports the boost state, it will have another boost state that the frequency can be higher than P0 state, and the state can be decoded by the function of decode_pstates() and read by amd_pci_get_num_boost_states(). However, the new AMD P-State function is different than legacy ACPI hardware P-State on AMD processors. That has a finer grain frequency range between the highest and lowest frequency. And boost frequency is actually the frequency which is mapped on highest performance ratio. The similar previous P0 frequency is mapped on nominal performance ratio. If the highest performance on the processor is higher than nominal performance, then we think the current processor supports the boost state. And it uses amd_pstate_boost_init() to initialize boost for AMD P-State function.

2021-05-04tools/power turbostat: Enable tsc_tweak for Elkhart Lake and Jasper LakeChen Yu1-1/+1
It was found that on Elkhart Lake the TSC frequency is driven by a separate crystal-clock domain, which is different from the BCLK domain which includes mperf. This has result in small different speed thus inconsistence between TSC and the mperf, which caused the Busy% to be higher than 100%. On this platform it seems that the mperf runs faster than tsc when the CPU is 100% utilized: delta tsc(18815473183) < delta mperf(18958403680) for 10 seconds. To align TSC with mperf, leverage the tsc_tweak mechanism introduced for cores newer than Skylake, so that TSC and mperf would be calculated in the same domain.

Currently the turbostat treats ICX the same way as SKX and shares the code among them. But one difference is that ICX does not support Package C6 Retention, unlike SKX and CLX. So this patch: 1. Splitting SKX and ICX in turbostat. 2. Removing Package C6 Rentention for ICX. And after this split, it would be easier to cutomize Ice Lake Server in turbostat in the future.

2021-05-04tools/power turbostat: Fix offset overflow issue in index convertingCalvin Walton1-5/+6
The idx_to_offset() function returns type int (32-bit signed), but MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number. The end result is that it hits the if (offset < 0) check in update_msr_sum() which prevents the timer callback from updating the stat in the background when long durations are used. The similar issue exists in offset_to_idx() and update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

2021-05-04tools/power/turbostat: Fix turbostat for AMD Zen CPUsBas Nieuwenhuizen1-2/+6
It was reported that on Zen+ system turbostat started exiting, which was tracked down to the MSR_PKG_ENERGY_STAT read failing because offset_to_idx wasn't returning a non-negative index. This patch combined the modification from Bingsong Si and Bas Nieuwenhuizen and addd the MSR to the index system as alternative for MSR_PKG_ENERGY_STATUS.

2021-05-04tools/power turbostat: add built-in-counter for IPC -- Instructions per CycleLen Brown1-0/+84
Use linux-perf to access the hardware instructions-retired counter. This is necessary because the counter is not enabled by default, and also the counter is prone to roll-over -- both of which perf manages. It is not necessary to use perf for the cycle counter, because turbostat already needs to collect delta-aperf to calcuate frequency. Signed-off-by: Len Brown <len.brown@intel.com>

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "These add some new hardware support (for example, IceLake-D idle states in intel_idle), fix some issues (for example, the handling of negative "sleep length" values in cpuidle governors), add new functionality to the existing drivers (for example, scale-invariance support in the ACPI CPPC cpufreq driver) and clean up code all over. Specifics: - Add idle states table for IceLake-D to the intel_idle driver and update IceLake-X C6 data in it (Artem Bityutskiy). - Fix the C7 idle state on Tegra114 in the tegra cpuidle driver and drop the unused do_idle() firmware call from it (Dmitry Osipenko). -
