2008-12-17Add HPET emulation to qemu (Beth Kon)aliguori1-0/+7
This patch adds HPET emulation. It can be disabled with -disable-hpet. An hpet provides a more finely granular clocksource than otherwise available on PC. This means that latency-dependent applications (e.g. multimedia) will generally be smoother when using the HPET.

2008-08-21De-assert PIC IRQs properly at APIC levelaurel321-1/+22
[ Taking latest isapc changes into account. ] Ensure that PIC-delivered IRQs are properly de-asserted in case the APIC is in EXTINT or FIXED mode (with level-triggering selected) on LINT0. Fixes EFI-BIOS boot issues. This patch also cleans up a bit the interface between PIC and APIC, making apic_local_deliver private again.
