2019-11-21tools/power/x86/intel-speed-select: Ignore missing config levelSrinivas Pandruvada
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.

2019-11-07tools/power/x86/intel-speed-select: Support platform with limited Intel(R) ↵Srinivas Pandruvada
Speed Select There are some platforms, where there limited support of Intel(R) SST features. Here perf-profile has only one base configuration and limited support of commands. But still has support for discovery of base-freq and turbo-freq features. So it is important to show minimum features to use base-freq and turbo-freq features. Here the change are: - When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead of treating this as fatal error, treat this with number of config levels = 0, that means only base level 0 is present. - There is no support of mail box commands to get base frequencies or turbo frequencies. Here present base frequency by reading cpufreq base freq and turbo frequency by reading MSR 0x1AD. - Don't display any field, which has value == 0.

There is an expectation in the CLX platform for SST base-freq feature that Scaling min frequency be different for high and low priority cores.

2019-11-05cpupower: mperf_monitor: Update cpupower to use the RDPRU instructionJanakarajan Natarajan
AMD Zen 2 introduces the RDPRU instruction which can be used to access some processor registers which are typically only accessible in privilege level 0. ECX specifies the register to read and EDX:EAX will contain the value read. ECX: 0 - Register MPERF 1 - Register APERF This has the added advantage of not having to use the msr module, since the userspace to kernel transitions which occur during each read_msr() might cause APERF and MPERF to go out of sync.

2019-11-05cpupower: mperf_monitor: Introduce per_cpu_schedule flagJanakarajan Natarajan
The per_cpu_schedule flag is used to move the cpupower process to the cpu on which we are looking to read the APERF/MPERF registers. This prevents IPIs from being generated by read_msr()s as we are already on the cpu of interest. Ex: If cpupower is running on CPU 0 and we execute read_msr(20, MSR_APERF, val) then, read_msr(20, MSR_MPERF, val) the msr module will generate an IPI from CPU 0 to CPU 20 to query for the MSR_APERF and then the MSR_MPERF in separate IPIs. This delay, caused by IPI latency, between reading the APERF and MPERF registers may cause both of them to go out of sync. The use of the per_cpu_schedule flag reduces the probability of this from happening. It comes at the cost of a negligible increase in cpu consumption caused by the migration of cpupower across each of the cpus of the system.
