What is the HPET I hear you ask? It is the High Precision Event Timer that is supposed to supplement and eventually replace the 8254 timer and the RTC periodic interrupts. Among other things, it is 64 bit (can be run in 32 bit mode for 32 bit cpus), and is suitable as a replacement for the ACPI timer on SMP systems (the specs are much better) and as a replacement for the ITC based synthetic clock for on ia64 systems. It seems IA64 and AMD64 systems tend to have this. It is likely to start showing up in i386 systems if it isn't already on some of them. |
