From 2af4f9b8596afbbd7667a18fa71d117bac227dea Mon Sep 17 00:00:00 2001 From: Len Brown Date: Sat, 30 Jan 2021 23:43:10 -0500 Subject: [PATCH 01/21] tools/power turbostat: add built-in-counter for IPC -- Instructions per Cycle Use linux-perf to access the hardware instructions-retired counter. 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.

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.

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.
