Module devices::irqchip::ioapic

Structs

• Ioapic
• IoapicSnapshot 🔒
  Snapshot of Ioapic state. Some fields were intentionally excluded:
• OutEvent 🔒
  Stores the outbound IRQ line in runtime & serializable forms.
• OutEventSnapshot 🔒
  This struct is essentially the complete serialized form of IrqEvent as used in Ioapic::out_events.

Enums

• IoapicError 🔒

Constants

• IOAPIC_BASE_ADDRESS
• IOAPIC_MEM_LENGTH_BYTES
• IOAPIC_REG_ARBITRATION_ID 🔒
• IOAPIC_REG_ID 🔒
• IOAPIC_REG_VERSION 🔒
• IOAPIC_VERSION_ID 🔒
• IOEOIR_OFF 🔒
• IOREGSEL_DUMMY_UPPER_32_BITS_OFF 🔒
• IOREGSEL_OFF 🔒
• IOWIN_OFF 🔒
• IOWIN_SCALE 🔒
• RTC_IRQ 🔒

Functions

• decode_irq_from_selector 🔒
  Given an offset that was read from/written to, return a tuple of the relevant IRQ and whether the offset refers to the high bits of that register.
• encode_selector_from_irq 🔒
  Given an IRQ and whether or not the selector should refer to the high bits, return a selector suitable to use as an offset to read to/write from.
