* tools/power/x86/intel-speed-select: Update max frequencySrinivas Pandruvada2021-12-241-0/+2
| | | | | | | | | | | | | | | | When BIOS disables turbo, the cpuinfo_max_freq will also be same as the power up base frequency. When SST-PP causes increase in base frequency the performance will be still limited to the old base frequency as the cpuinfo_max_freq will not be updated. In this case we need to update scaling_max frequency to the new base_frequency. This will result in setting updated max performance limit in the Pstate driver. So performance will not be limited to the old base frequency.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two TCC activation temeprature. One is the default TCC activation temperature, also known as TJ_MAX. Another one is the effective TCC activation temperature, which is the subtraction of default TCC activation temperature and TCC offset. The name of variable tcc_activation_temp might be misleading here. Thus rename tcc_activation_temp to tj_max, and use tcc_default and tcc_offset to calculate the effective TCC activation temperature. No functional change in this patch. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| * tools/power turbostat: Enable tsc_tweak for Elkhart Lake and Jasper LakeChen Yu2021-05-041-1/+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.

| * tools/power/turbostat: Remove Package C6 Retention on Ice Lake ServerChen Yu2021-05-041-6/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * tools/power turbostat: Fix offset overflow issue in index convertingCalvin Walton2021-05-041-5/+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.

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>

| * | tools/power/x86/intel-speed-select: Account for missing sysfs for die_idSrinivas Pandruvada2020-12-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some older kernels will not have support to get CPU die_id from the sysfs. This requires several back ports. But the tool depends on getting die_id to match to correct CPU. Relax this restriction and use die_id as 0 when die_id is missing. This is not a problem as we don't have any multi-die processors with Intel SST support. This helps in running this tool on older kernels with just Intel SST drivers back ported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When SST-PP feature is not present, the TRL (Turbo Ratio Limits) is read from MSRs. This is done as the mailbox command will fail on Skylake-X based platform. But for IceLake servers, mailbox commands can still be used. So add a check to allow for non Skylake based platforms to read from mail box commands.
