Name | Describe |

__ioapic_write_entry | When we write a new IO APIC routing entry, we need to write the high* word first! If the mask bit in the low word is clear, we will enable* the interrupt, and we need to make sure the entry is fully populated* before that happens. |
ioapic_mask_entry | When we mask an IO APIC routing entry, we need to write the low* word first, in order to set the mask bit before we change the* high bits! |
