This is especially useful for dynamic ticks / "tickless systems", but is also of interest on normal systems, as any interrupt activity leads to C-States being exited, not only the timer interrupt. The time is being measured in PM timer ticks, so an increase by one equals 279 nanoseconds. Signed-off-by: Dominik Brodowski Signed-off-by: Andrew Morton Signed-off-by: Len Brown
