Why don't use C2/C3 with high latency?
Hi,
on my system (Gigabyte GA-7VTXH, VIA KT266A Chipset, Athlon XP 1600+) the C2 processor powerstate have not been enabled until I set the ACPI_PROCESSOR_MAX_C2_LATENCY to a value above 100. The system runs quite normal after this change and consumes much less power than before. Also the processor temperature goes down from 48°C to under 35°C when idle.
So why is the MAX_C2_LATENCY set to this value? Is it possible to optimize the use of this high latency C2 to only use it when the system is _really_ idle?
