John Baldwin 6f92bdd0c1 New APIC support code: ... - The apic interrupt entry points have been rewritten so that each entry point can serve 32 different vectors. When the entry is executed, it uses one of the 32-bit ISR registers to determine which vector in its assigned range was triggered. Thus, the apic code can support 159 different interrupt vectors with only 5 entry points. - We now always to disable the local APIC to work around an errata in certain PPros and then re-enable it again if we decide to use the APICs to route interrupts. - We no longer map IO APICs or local APICs using special page table entries. Instead, we just use pmap_mapdev(). We also no longer export the virtual address of the local APIC as a global symbol to the rest of the system, but only in local_apic.c. To aid this, the APIC ID of each CPU is exported as a per-CPU variable. - Interrupt sources are provided for each intpin on each IO APIC. Currently, each source is given a unique interrupt vector meaning that PCI interrupts are not shared on most machines with an I/O APIC. That mapping for interrupt sources to interrupt vectors is up to the APIC enumerator driver however. - We no longer probe to see if we need to use mixed mode to route IRQ 0, instead we always use mixed mode to route IRQ 0 for now. This can be disabled via the 'NO_MIXED_MODE' kernel option. - The npx(4) driver now always probes to see if a built-in FPU is present since this test can now be performed with the new APIC code. However, an SMP kernel will panic if there is more than one CPU and a built-in FPU is not found. - PCI interrupts are now properly routed when using APICs to route interrupts, so remove the hack to psuedo-route interrupts when the intpin register was read. - The apic.h header was moved to apicreg.h and a new apicvar.h header that declares the APIs used by the new APIC code was added.		2003-11-03 21:53:38 +00:00
