tools/power turbostat: Fix missing SYS_LPI counter on some Chromebooks

2020-04-08T07:09:58+00:00

[ Upstream commit 1f81c5efc020314b2db30d77efe228b7e117750d ] Some Chromebook BIOS' do not export an ACPI LPIT, which is how Linux finds the residency counter for CPU and SYSTEM low power states, that is exports in /sys/devices/system/cpu/cpuidle/*residency_us When these sysfs attributes are missing, check the debugfs attrubte from the pmc_core driver, which accesses the same counter value.

cpupower: Revert library ABI changes from commit ae2917093fb60bdc1ed3e

2020-02-11T12:36:54+00:00

commit 41ddb7e1f79693d904502ae9bea609837973eff8 upstream. Commit ae2917093fb6 ("tools/power/cpupower: Display boost frequency separately") modified the library function: struct cpufreq_available_frequencies *cpufreq_get_available_frequencies(unsigned int cpu) to struct cpufreq_frequencies *cpufreq_get_frequencies(const char *type, unsigned int cpu) This patch recovers the old API and implements the new functionality in a newly introduce method: struct cpufreq_boost_frequencies *cpufreq_get_available_frequencies(unsigned int cpu) This one should get merged into stable kernels back to 5.0 when the above had been introduced.

2019-12-02T02:24:25+00:00

Pull x86 platform driver updates from Andy Shevchenko: - New bootctl driver for Mellanox BlueField SoC. - New driver to support System76 laptops. - Temperature monitoring and fan control on Acer Aspire 7551 is now supported. - Previously the Huawei driver handled only hotkeys. After the conversion to WMI it has been expanded to support newer laptop models. - Big refactoring of intel-speed-select tools allows to use it on Intel CascadeLake-N systems. - Touchscreen support for ezpad 6 m4 and Schneider SCT101CTM tablets - Miscellaneous clean ups and fixes here and there. * tag 'platform-drivers-x86-v5.5-1' of git://git.infradead.org/linux-platform-drivers-x86: (59 commits) platform/x86: hp-wmi: Fix ACPI errors caused by passing 0 as input size platform/x86: hp-wmi: Fix ACPI errors caused by too small buffer platform/x86: intel_pmc_core: Add Comet Lake (CML) platform support to intel_pmc_core driver platform/x86: intel_pmc_core: Fix the SoC naming inconsistency platform/mellanox: Fix Kconfig indentation tools/power/x86/intel-speed-select: Display TRL buckets for just base config level tools/power/x86/intel-speed-select: Ignore missing config level platform/x86: touchscreen_dmi: Add info for the ezpad 6 m4 tablet tools/power/x86/intel-speed-select: Increment version tools/power/x86/intel-speed-select: Use core count for base-freq mask tools/power/x86/intel-speed-select: Support platform with limited Intel(R) Speed Select tools/power/x86/intel-speed-select: Use Frequency weight for CLOS tools/power/x86/intel-speed-select: Make CLOS frequency in MHz tools/power/x86/intel-speed-select: Use mailbox for CLOS_PM_QOS_CONFIG tools/power/x86/intel-speed-select: Auto mode for CLX tools/power/x86/intel-speed-select: Correct CLX-N frequency units tools/power/x86/intel-speed-select: Change display of "avx" to "avx2" tools/power/x86/intel-speed-select: Extend command set for perf-profile Add touchscreen platform data for the Schneider SCT101CTM tablet platform/x86: intel_int0002_vgpio: Pass irqchip when adding gpiochip ...

tools/power/x86/intel-speed-select: Display TRL buckets for just base config level

2019-11-21T12:31:34+00:00

When only base config level is present, this tool is displaying TRL (Turbo-ratio-limits) by reading legacy MSR. In this case, also present core count for TRL by reading MSR 0x1AE. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Ignore missing config level

2019-11-21T12:27:32+00:00

It is possible that certain config levels are not available, even if the max level includes the level. There can be missing levels in some platforms. So ignore the level when called for information dump for all levels and fail if specifically ask for the missing level. Here the changes is to continue reading information about other levels even if we fail to get information for the current level. But use the "processed" flag to indicate the failure. When the "processed" flag is not set, don't dump information about that level. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko
