New Revision: 258075
URL: http://svnweb.freebsd.org/changeset/base/258075
Log:
Move the ioapic device model from userspace into vmm.ko. This is needed for
upcoming in-kernel device emulations like the HPET.
The ioctls VM_IOAPIC_ASSERT_IRQ and VM_IOAPIC_DEASSERT_IRQ are used to
manipulate the ioapic pin state.
