HPET Support
HPET, or High Precision Event Timer (formerly known as Multimedia
Timer) is a hardware timer that is supported under Linux and Windows
Vista. It can produce periodic interrupts at a much higher resolution than
the RTC and is often used to synchronize multimedia streams, providing
smooth playback and reducing the need to use other timestamp
calculations such as an x86 CPU‟s RDTSC instruction.
