2023-05-24cpupower: Make TSC read per CPU for Mperf monitorWyes Karny
[ Upstream commit c2adb1877b76fc81ae041e1db1a6ed2078c6746b ] System-wide TSC read could cause a drift in C0 percentage calculation. Because if first TSC is read and then one by one mperf is read for all cpus, this introduces drift between mperf reading of later CPUs and TSC reading. To lower this drift read TSC per CPU and also just after mperf read. This technique improves C0 percentage calculation in Mperf monitor.

2022-07-28tools/power turbostat: do not decode ACC for ICX and SPRArtem Bityutskiy
The ACC (automatic C-state conversion) feature was available on Sky Lake and Cascade Lake Xeons (SKX and CLX), but it is not available on Ice Lake and Sapphire Rapids Xeons (ICX and SPR). Therefore, stop decoding it for ICX and SPR. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2022-07-28tools/power turbostat: fix SPR PC6 limitsArtem Bityutskiy
Sapphire Rapids Xeon (SPR) supports 2 flavors of PC6 - PC6N (non-retention) and PC6R (retention). Before this patch we used ICX package C-state limits, which was wrong, because ICX has only one PC6 flavor. With this patch, we use SKX PC6 limits for SPR, because they are the same.

2022-07-28tools/power turbostat: separate SPR from ICXArtem Bityutskiy

2022-07-28tools/power turbostat: Show uncore frequencyLen Brown
When CONFIG_INTEL_UNCORE_FREQ_CONTROL is effective, (Linux 5.9 and later), print the current (and default) min and max uncore frequency limits. When that driver provides the current uncore frequency (Linux 5.18 and later), print a UncMHz column reflecting the current uncore frequency. Note that UncMHz is an instantaneous sample, not an average. eg. $ sudo ./turbostat -S --show frequency ... Uncore Frequency pkg0 die0: 800 - 3900 MHz (800 - 3900 MHz) ...

2022-07-28tools/power turbostat: Fix file pointer leakColin Ian King
Currently if a fscanf fails then an early return leaks an open file pointer. Fix this by fclosing the file before the return.

2022-07-28tools/power turbostat: replace strncmp with single character compareColin Ian King
Using strncmp for a single character comparison is overly complicated, just use a simpler single character comparison instead.

2022-07-28tools/power turbostat: print the kernel boot commandlineChen Yu
It would be handy to have cmdline in turbostat output. For example, according to the turbostat output, there are no C-states requested. In this case the user is very curious if something like intel_idle.max_cstate=0 was used, or may be idle=none too. It is also curious whether things like intel_pstate=nohwp were used. Print the boot command line accordingly: turbostat version 21.05.04 - Len Brown <lenb@kernel.org> Kernel command line: BOOT_IMAGE=/boot/vmlinuz-5.16.0+ root=UUID= b42359ed-1e05-42eb-8757-6bf2a1c19070 ro quiet splash vt.handoff=7 Suggested-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: Chen Yu <yu.c.chen@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
