io-apic

Description

Interfaces Implemented

Notifiers

cell-change

Notifier that is triggered after the object's cell was changed.

object-delete

Notifier that is triggered just before Simics object is deleted.

queue-change

Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.

Port Objects

port.RESET

io-apic.RESET – Reset pin.

Commands for this class

• info – print information about the object
• status – print status of the object

Attributes

apic_bus

Optional attribute; read/write access; type: o|[os]|n
Connected bus object of class apic-bus.

mem_msi

Optional attribute; read/write access; type: o|n
Object implementing io_memory interface which will receive MSI signals. If not set apic-bus will be used

ioapic_id

Optional attribute; read/write access; type: i
The ID of this io-apic object.

ibdf_def_value

Optional attribute; read/write access; type: i
Default value of the IBDF register used if lpc isn't connected

register_select

Optional attribute; read/write access; type: i
Register selected for reading/writing (will affect the next transaction).

redirection

Optional attribute; read/write access; type: [i*]
Represents the redirection table, where each interrupt input signal has a dedicated entry.

pin_raised

Optional attribute; read/write access; type: [i*]
A one in the corresponding index means that the input pin is high, while a zero means that it is low.

int_deliver_status

Optional attribute; read/write access; type: [i*]
Interrupt acceptance status.

edid_size

Optional attribute; read/write access; type: i
RW part of EDID field in redirection entry. Writable EDID is [48 + edid_size - 1 : 48]. Zero means no EDID.

ioapic_version

Optional attribute; read/write access; type: i
I/O apic implementation version (Indirect register 1).

ioapic_version_once_ref

Optional attribute; read/write access; type: i
Initialize to 0 to enable RWO behavior on the IOAPIC version register. Otherwise (the default) the register is read-only. Allowed values are: 0=RWO not yet written, 1=RWO written, 2=always read-only.

redirection_vector_read_only

Optional attribute; read/write access; type: b
Set to True if interrupt vectors in redirection table should be read-only

boot_configuration

Optional attribute; read/write access; type: i
BCFG register (Indirect register 3).
