Detailed Description

Vbus Interrupt controller API.

Every Vbus contains a virtual interrupt control unit that manages the IRQs of the devices on the bus. This class provides access to a capability to an L4::Icu object which can then be used to interface with the IRQs.

Member Enumeration Documentation

◆ Src_types

enum L4vbus::Icu::Src_types

Flags that can be used with the ICU on a vbus device.

Enumerator

Src_dev_handle

Flag to denote that the value should be interpreted as a device handle.

This flag may be used in the source parameter in L4::Icu::msi_info() to denote that the ICU should interpret the source ID as a device handle.

Member Function Documentation

◆ vicu()

int L4vbus::Icu::vicu ( L4::Cap< L4::Icu > icu ) const

inline

Request an L4::Icu capability for this Vbus's virtual ICU.

Parameters

[out] icu Capability slot where the L4::Icu capability shall be stored.

Return values

0	Success.
otherwise	IPC error.
