tools/power turbostat: add [-d MSR#][-D MSR#] options to print counter deltas
# turbostat -d 0x34 is useful for printing the number of SMI's within an interval on Nehalem and newer processors. where # turbostat -m 0x34 will simply print out the total SMI count since reset. Suggested-by: Andi Kleen Signed-off-by: Len Brown <len.brown@intel.com>

the arithmetic average of the GHz column above is lower.

This is a weighted average, where the weight is %c0. ie. it is the total number of

un-halted cycles elapsed per time divided by the number of CPUs.

.SH SMI COUNTING EXAMPLE
|
||||
On Intel Nehalem and newer processors, MSR 0x34 is a System Management Mode Interrupt (SMI) counter.
|
||||
Using the -m option, you can display how many SMIs have fired since reset, or if there
|
||||
are SMIs during the measurement interval, you can display the delta using the -d option.
