参数:
类型 | 参数 | 名称 |
---|---|---|
unsigned int | apic | |
unsigned int | pin |
550 | entry等于ioapic_read_entry(apic, pin) |
551 | 如果 000: FIXED * 001: lowest prio * 111: ExtINT恒等于dest_SMI则返回 |
558 | 如果 0: enabled, 1: disabled 恒等于IOAPIC_UNMASKED则 |
560 | ioapic_write_entry(apic, pin, entry) |
561 | entry等于ioapic_read_entry(apic, pin) |
564 | 如果irr则 |
572 | 如果 0: edge, 1: level 恒等于IOAPIC_EDGE则 |
574 | ioapic_write_entry(apic, pin, entry) |
576 | raw_spin_lock_irqsave( & ioapic_lock, flags) |
578 | raw_spin_unlock_irqrestore( & ioapic_lock, flags) |

名称 | 描述 |

clear_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. |
