Power management turbostat utility updates for v4.11-rc1
These update turbostat significantly and in particular:
- Default output is now verbose, --debug is no longer required to
get all counters. As a result, some options have been added to
specify exactly what output is wanted.
- Added --quiet to skip system configuration output
- Added --list, --show and --hide parameters
- Added --cpu parameter
- Enhanced Baytrail SoC support
- Added Gemini Lake SoC support
- Added sysfs C-state columns
Also the symbol definitions in arch/x86/include/asm/intel-family.h
and arch/x86/include/asm/msr-index.h are updated and the intel_idle
and intel_pstate drivers are modified to use the updated symbols.
Credits to Len Brown for all of these changes.

.SH ROW DESCRIPTIONS
|
||||
The system configuration dump (if --quiet is not used) is followed by statistics. The first row of the statistics labels the content of each column (below). The second row of statistics is the system summary line. The system summary line has a '-' in the columns for the Package, Core, and CPU. The contents of the system summary line depends on the type of column. Columns that count items (eg. IRQ) show the sum across all CPUs in the system. Columns that show a percentage show the average across all CPUs in the system. Columns that dump raw MSR values simply show 0 in the summary. After the system summary row, each row describes a specific Package/Core/CPU. Note that if the --cpu parameter is used to limit which specific CPUs are displayed, turbostat will still collect statistics for all CPUs in the system and will still show the system summary for all CPUs in the system.

.SH TOO MUCH INFORMATION EXAMPLE
|
||||
By default, turbostat dumps all possible information -- a system configuration header, followed by columns for all counters.
|
||||
This is ideal for remote debugging, use the "--out" option to save everything to a text file, and get that file to the expert helping you debug.
|
||||
.PP
|
||||
.SH PERIODIC EXAMPLE
|
||||
Without any parameters, turbostat displays statistics ever 5 seconds.
|
||||
Periodic output goes to stdout, by default, unless --out is used to specify an output file.
|
||||
The 5-second interval can be changed with th "-i sec" option.
|
||||
Or a command may be specified as in "FORK EXAMPLE" below.
|
||||
When you are not interested in all that information, and there are several ways to see only what you want. First the "--quiet" option will skip the configuration information, and turbostat will show only the counter columns. Second, you can reduce the columns with the "--hide" and "--show" options. If you use the "--show" option, then turbostat will show only the columns you list. If you use the "--hide" option, turbostat will show all columns, except the ones you list.
|
||||
.PP
|
||||
To find out what columns are available for --show and --hide, the "--list" option is available. For convenience, the special strings "sysfs" can be used to refer to all of the sysfs C-state counters at once:

.SH DEBUG EXAMPLE
|
||||
The "--debug" option prints additional system information before measurements:
|
||||
.PP
|
||||
.SH ONE SHOT COMMAND EXAMPLE
|
||||
If turbostat is invoked with a command, it will fork that command
|
||||
and output the statistics gathered after the command exits.
|
||||
In this case, turbostat output goes to stderr, by default.
|
||||
Output can instead be saved to a file using the --out option.
|
||||
In this example, the "sleep 10" command is forked, and turbostat waits for it to complete before saving all statistics into "ts.out". Note that "sleep 10" is not part of turbostat, but is simply an example of a command that turbostat can fork. The "ts.out" file is what you want to edit in a very wide window, paste into a spreadsheet, or attach to a bugzilla entry.
|
||||
|
||||
The first row of statistics is a summary for the entire system.
|
||||
For residency % columns, the summary is a weighted average.
|
||||
For Temperature columns, the summary is the column maximum.
|
||||
For Watts columns, the summary is a system total.
|
||||
Subsequent rows show per-CPU statistics.

|

|

.SH PERIODIC INTERVAL EXAMPLE
|
||||
Without a command to fork, turbostat displays statistics ever 5 seconds.
|
||||
Periodic output goes to stdout, by default, unless --out is used to specify an output file.
|
||||
The 5-second interval can be changed with the "-i sec" option.

This example also shows the use of the --hide option to skip columns that are not wanted.
|
||||
Note that cpu4 in this example is 99.99% busy, while the other CPUs are all under 1% busy.
|
||||
Notice that cpu4's HT sibling is cpu0, which is under 1% busy, but can get into CPU%c1 only,
|
||||
because its cpu4's activity on shared hardware keeps it from entering a deeper C-state.

.SH SYSTEM CONFIGURATION INFORMATION EXAMPLE
|
||||
|
||||
By default, turbostat always dumps system configuration information
|
||||
before taking measurements. In the example above, "--quiet" is used
|
||||
to suppress that output. Here is an example of the configuration information:

The first row shows the average MHz and Busy% across all the processors in the system.

Note that the Avg_MHz column reflects the total number of cycles executed

divided by the measurement interval. If the Busy% column is 100%,

then the processor was running at that speed the entire interval.
