From bb24c4716185f6e116c440462c65c1f56649183b Mon Sep 17 00:00:00 2001 From: Jacob Pan Date: Wed, 2 Sep 2009 07:37:17 -0700 Subject: x86, apbt: Moorestown APB system timer driver Moorestown platform does not have PIT or HPET platform timers. Instead it has a bank of eight APB timers. The number of available timers to the os is exposed via SFI mtmr tables. All APB timer interrupts are routed via ioapic rtes and delivered as MSI. Currently, we use timer 0 and 1 for per cpu clockevent devices, timer 2 for clocksource.
