John Baldwin c7362ff7fb Change the x86 code to allocate IDT vectors on-demand when an interrupt ... source is first enabled similar to how intr_event's now allocate ithreads on-demand. Previously, we would map IDT vectors 1:1 to IRQs. Since we only have 191 available IDT vectors for I/O interrupts, this limited us to only supporting IRQs 0-190 corresponding to the first 190 I/O APIC intpins. On many machines, however, each PCI-X bus has its own APIC even though it only has 1 or 2 devices, thus, we were reserving between 24 and 32 IRQs just for 1 or 2 devices and thus 24 or 32 IDT vectors. With this change, a machine with 100 IRQs but only 5 in use will only use up 5 IDT vectors. Also, this change provides an API (apic_alloc_vector() and apic_free_vector()) that will allow a future MSI interrupt source driver to request IDT vectors for use by MSI interrupts on x86 machines. Tested on: amd64, i386		2005-11-02 20:11:47 +00:00
