idlestat - 0.8-8+b1 main

Idlestat uses kernel FTRACE function to monitor and capture C-state and
P-state transitions of CPUs over a time interval. It calculates the total,
average, min and max times spend in each C-state, P-state for each CPU and in
each CPU cluster. It also reports the times specific IRQs caused the CPU
to exit idle state, per CPU and per-IRQ.
