.SH DESCRIPTION
|
||||
\fBturbostat \fP reports processor topology, frequency,
|
||||
idle power-state statistics, temperature and power on modern X86 processors.
|
||||
Either \fBcommand\fP is forked and statistics are printed
|
||||
upon its completion, or statistics are printed periodically.
|
||||
|
||||
\fBturbostat \fP
|
||||
must be run on root, and
|
||||
minimally requires that the processor
|
||||
supports an "invariant" TSC, plus the APERF and MPERF MSRs.
|
||||
Additional information is reported depending on hardware counter support.
|
||||
idle power-state statistics, temperature and power on X86 processors.
|
||||
There are two ways to invoke turbostat.
|
||||
The first method is to supply a
|
||||
\fBcommand\fP, which is forked and statistics are printed
|
||||
upon its completion.
|
||||
The second method is to omit the command,
|
||||
and turbodstat will print statistics every 5 seconds.
|
||||
The 5-second interval can changed using the -i option.
|
||||
|
||||
Some information is not availalbe on older processors.
|
||||

The \fBmax efficiency\fP frequency, a.k.a. Low Frequency Mode, is the frequency

available at the minimum package voltage. The \fBTSC frequency\fP is the nominal

maximum frequency of the processor if turbo-mode were not available. This frequency

frequency of the processor -- this should match the brand string

should be sustainable on all CPUs indefinitely, given nominal power and cooling.

\fBturbostat \fP

|

|
||||
If the TSC column does not make sense, then
|
||||
the other numbers will also make no sense.
|
||||
Turbostat is lightweight, and its data collection is not atomic.
|
||||
These issues are usually caused by an extremely short measurement
|
||||
interval (much less than 1 second), or system activity that prevents
|
||||
turbostat from being able to run on all CPUS to quickly collect data.
|
||||
AVG_MHz = APERF_delta/measurement_interval. This is the actual
|
||||
number of elapsed cycles divided by the entire sample interval --
|
||||
including idle time. Note that this calculation is resiliant
|
||||
to systems lacking a non-stop TSC.
|
||||
|
||||
TSC_MHz = TSC_delta/measurement_interval.
|
||||
On a system with an invariant TSC, this value will be constant
|
||||
and will closely match the base frequency value shown
|
||||
in the brand string in /proc/cpuinfo. On a system where
|
||||
the TSC stops in idle, TSC_MHz will drop
|
||||
below the processor's base frequency.
|
||||
|
||||
%Busy = MPERF_delta/TSC_delta
|
||||
|
||||
Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval
|
||||
|
||||
Note that these calculations depend on TSC_delta, so they
|
||||
are not reliable during intervals when TSC_MHz is not running at the base frequency.

Turbostat data collection is not atomic.
|
||||
Extremely short measurement intervals (much less than 1 second),
|

or system activity that prevents turbostat from being able
|

to run on all CPUS to quickly collect data, will result in

inconsistent results.

The APERF, MPERF MSRs are defined to count non-halted cycles.
