tools: create power/x86/turbostat turbostat is a Linux tool to observe proper operation of Intel(R) Turbo Boost Technology. turbostat displays the actual processor frequency on x86 processors that include APERF and MPERF MSRs. Note that turbostat is of limited utility on Linux kernels 2.6.29 and older, as acpi_cpufreq cleared APERF/MPERF up through that release. On Intel Core i3/i5/i7 (Nehalem) and newer processors, turbostat also displays residency in idle power saving states, which are necessary for diagnosing any cpuidle issues that may have an effect on turbo-mode. See the turbostat.8 man page for example usage. Signed-off-by: Len Brown <len.brown@intel.com> 2010-10-22 23:53:03 -04:00			`turbostat : turbostat.c`
tools/power: turbostat v2 - re-write for efficiency Measuring large profoundly-idle configurations requires turbostat to be more lightweight. Otherwise, the operation of turbostat itself can interfere with the measurements. This re-write makes turbostat topology aware. Hardware is accessed in "topology order". Redundant hardware accesses are deleted. Redundant output is deleted. Also, output is buffered and local RDTSC use replaces remote MSR access for TSC. From a feature point of view, the output looks different since redundant figures are absent. Also, there are now -c and -p options -- to restrict output to the 1st thread in each core, and the 1st thread in each package, respectively. This is helpful to reduce output on big systems, where more detail than the "-s" system summary is desired. Finally, periodic mode output is now on stdout, not stderr. Turbostat v2 is also slightly more robust in handling run-time CPU online/offline events, as it now checks the actual map of on-line cpus rather than just the total number of on-line cpus.

tools/power/x86/turbostat: share kernel MSR #defines Now that turbostat is built in the kernel tree, it can share MSR #defines with the kernel. Signed-off-by: Len Brown <len.brown@intel.com> Cc: x86@kernel.org 2012-10-31 01:29:52 -04:00			`CFLAGS += -I../../../../arch/x86/include/`
