H A D | processor.h | a3c6598f Sat Jun 24 18:37:00 CDT 2006 Dominik Brodowski <linux@dominikbrodowski.net> ACPI: C-States: accounting of sleep states
Track the actual time spent in C-States (C2 upwards, we can't determine this for C1), not only the number of invocations. 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.
