-Move the local apic driver to arch/x86
-Add routines to send IPIs between cpus
Something is unstable at the moment and the system crashes after a while
with random corruptions when using SMP.
Extend the PIT driver to allow for one shot timers even though it
monotonically runs a 1kHz tick. This allows it to keep time and provide
one shot events, though only at 1ms resolution.
-Add a bus manager level, which is an object oriented walk of the pci
busses to build a per device object for later manipulation.
-Add features to enable MSI interrupts.
-Extend generic interrupt api to allow the platform to allocate vectors
for MSI interrupts.
-Rearrange a bit of the pc platform for the platform api changes.
-Add PC platform support for using the local apic to EOI MSI vectors.
-Fix up a few existing PCI drivers for small API changes.
-Add a few stubbed out routines for non PC platforms that use PCI.
This is especially useful when using the "nographic" option of qemu like this:
qemu -kernel build-pc-x86/lk.bin -nographic
Define WITH_CGA_CONSOLE=1 to enable the CGA console instead.
