Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Fix Core C6 residency on Atom CPUsZhang Rui2021-05-041-1/+38
| | | | | | | | | | | | | | | | | | | | | | For Atom CPUs that have core cstate deeper than C6, MSR_CORE_C6_RESIDENCY actually returns the residency for both CC6 and deeper Core cstates. Thus, the real Core C6 residency should be the subtraction of MSR_CORE_C6_RESIDENCY return value and MSR_CORE_C6_RESIDENCY return value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C-state pre-wake setting[1] is an optimization for some Intel CPUs to be woken up from deep C-states in order to reduce latency. According to the spec, the BIT30 is the C-state Pre-wake Disable. Expose this setting accordingly. Sample output from turbostat: ... cpu51: MSR_IA32_POWER_CTL: 0x1a00a40059 (C1E auto-promotion: DISabled) C-state Pre-wake: ENabled cpu51: MSR_TURBO_RATIO_LIMIT: 0x2021212121212224 ...

| * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
