| int | irq | |
| int | type |
| 741 | When i < # of MP IRQ source entries cycle |
| 744 | If st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from && irqtype == type && srcbusirq == irq Then Break |

| 754 | If mpc_ioapic_id(ioapic_idx) == dstapic Then Return ioapic_idx |
| 758 | Return -1 |
| Name | Describe |
|---|---|
| enable_IO_APIC | |
| unlock_ExtINT_logic | This looks a bit hackish but it's about the only one way of sending* a few INTA cycles to 8259As and any associated glue logic |
| check_timer | This code may look a bit paranoid, but it's supposed to cooperate with* a wide range of boards and BIOS bugs. Fortunately only the timer IRQ* is so screwy. Thanks to Brian Perkins for testing/hacking this beast* fanatically on his truly buggy board. |
