tools/power turbostat: show IRQs per CPU
Orabug:
24811361
The new IRQ column shows how many interrupts have occurred on each CPU
during the measurement inteval. This information comes from
the difference between /proc/interrupts shapshots made before
and after the measurement interval.
The first row, the system summary, shows the sum of the IRQS
for all CPUs during that interval.
