cpupower: Introduce ACPI CPPC library

2022-02-23T01:36:50Z

Kernel ACPI subsytem introduced the sysfs attributes for acpi cppc library in below path: /sys/devices/system/cpu/cpuX/acpi_cppc/ And these attributes will be used for AMD P-State driver to provide some performance and frequency values.

cpupower: Add the function to get the sysfs value from specific table

2022-02-23T01:36:44Z

Expose the helper into cpufreq header, then cpufreq driver can use this function to get the sysfs value if it has any specific sysfs interfaces. Reviewed-by: Shuah Khan Signed-off-by: Huang Rui Signed-off-by: Shuah Khan

tools/power/cpupower: Read energy_perf_bias from sysfs

2020-11-16T16:42:12Z

... instead of poking at the MSR. For that, move the accessor functions to misc.c and add a sysfs-writing function too. There should be no functional changes resulting from this.

cpupower: Revert library ABI changes from commit ae2917093fb60bdc1ed3e

2020-01-17T22:21:42Z

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.

tools/power/cpupower: Display boost frequency separately

2019-02-13T16:26:17Z

cpufreq driver creates sysfs file "scaling_boost_frequency" for platforms which support boost frequency. Cpupower now prints boost frequencies separately. For few x86 vendors who already have different way to get boost frequency, will continue to use the existing logic. Rest of the platforms will rely on "scaling_boost_frequency" file to display boost frequency. Signed-off-by: Abhishek Goel Signed-off-by: Shuah Khan
