Arun Thomas ae561b8f12 Add MKAPIC and MKACPI options 2011-07-31 16:22:43 +02:00
Tomas Hruby ebbc730fc3 spurious and error interrupt apic handlers 
- fixed spurious and error interrupt handlers

- not to hog the system the warning isn't reported every time, just
  once every 100 times, similarly for the spurious PIC interrupts

Tomas Hruby b7aed08e65 SMP - Only a single APIC timer handler 
- bsp_timer_int_handler() and ap_timer_int_handler() unified into
  timer_int_handler()

- global realtime updated only on BSP

Tomas Hruby e6ebac015d APIC mode uses IO APICs 
- kernel turns on IO APICs if no_apic is _not_ set or is equal 0

- pci driver must use the acpi driver to setup IRQ routing otherwise
  the system cannot work correctly except systems like KVM that use
  only legacy (E)ISA IRQs 0-15

Arun Thomas 4ed3a0cf3a Convert kernel over to bsdmake 2010-04-01 22:22:33 +00:00
Tomas Hruby 8a44a44cb9 Local APIC 
- local APIC timer used as the source of time

- PIC is still used as the hw interrupt controller as we don't have
  enough info without ACPI or MPS to set up IO APICs

- remapping of APIC when switching paging on, uses the new mechanism
  to tell VM what phys areas to map in kernel's virtual space

- one more step to SMP
