tools/power turbostat: update parameters, documentation
Long format options added, though the short ones should still work. eg. the new "--Counter 0x10" is the same as the old "-C 0x10" Note this Incompatibility: Old: -v displayed verbose debug output New: -v and --version simpaly display version Additional parameters: -d and --debug display verbose debug output -h and --help display a help message Updated turbosat.8 man page accordingly.

.PP
|

The \fB-S\fP option limits output to a 1-line System Summary for each interval.
|

\fB--Dump\fP displays the raw counter values.
|
||||
.PP
|
||||
The \fB-v\fP option increases verbosity.
|

\fB--debug\fP displays additional system configuration information. Invoking this parameter
|
||||
more than once may also enable internal turbostat debug information.
|
||||
.PP
|

.PP
|

.PP
|

The \fB-m MSR#\fP option includes the the specified 32-bit MSR value.
|

\fB--Joules\fP displays energy in Joules, rather than dividing Joules by time to print power in Watts.
|

.PP
|

\fB--MSR MSR#\fP shows the specified 64-bit MSR value.

The \fBcommand\fP parameter forks \fBcommand\fP and upon its exit,

\fB--processor\fP limits output to the system summary plus the 1st thread in each processor of each package. Ie. it skips hyper-threaded siblings.
