IOCTL_1394_CLASS IOCTL

Description

An IEEE 1394 driver uses the IRP_MJ_INTERNAL_DEVICE_CONTROL IRP, with IoControlCode IOCTL_1394_CLASS, to communicate with the bus driver. The driver has access to all operations provided by the IEEE 1394 bus and its host controller through this request.

Parameters

Major code

Input buffer

Parameters->Others.Arguments1 points to an IRB structure. The FunctionNumber member of the IRB specifies the type of request. The u member of the IRB is a union that specifies the request-type-specific parameters of the request. The parameters and their meaning are documented with each request.

Legal requests are as follows:

REQUEST_ALLOCATE_ADDRESS_RANGE

REQUEST_ASYNC_LOCK

REQUEST_ASYNC_READ

REQUEST_ASYNC_STREAM

REQUEST_ASYNC_WRITE

REQUEST_BUS_RESET

REQUEST_BUS_RESET_NOTIFICATION

REQUEST_CONTROL

REQUEST_FREE_ADDRESS_RANGE

REQUEST_GET_ADDR_FROM_DEVICE_OBJECT

REQUEST_GET_CONFIGURATION_INFO

REQUEST_GET_GENERATION_COUNT

REQUEST_GET_LOCAL_HOST_INFO

REQUEST_GET_SPEED_BETWEEN_DEVICES

REQUEST_GET_SPEED_TOPOLOGY_MAPS

REQUEST_ISOCH_ALLOCATE_BANDWIDTH

REQUEST_ISOCH_ALLOCATE_CHANNEL

REQUEST_ISOCH_ALLOCATE_RESOURCES

REQUEST_ISOCH_ATTACH_BUFFERS

REQUEST_ISOCH_DETACH_BUFFERS

REQUEST_ISOCH_FREE_BANDWIDTH

REQUEST_ISOCH_FREE_CHANNEL

REQUEST_ISOCH_FREE_RESOURCES

REQUEST_ISOCH_LISTEN

REQUEST_ISOCH_QUERY_CYCLE_TIME

REQUEST_ISOCH_QUERY_RESOURCES

REQUEST_ISOCH_SET_CHANNEL_BANDWIDTH

REQUEST_ISOCH_STOP

REQUEST_ISOCH_TALK

REQUEST_SEND_PHY_CONFIG_PACKET

REQUEST_SET_DEVICE_XMIT_PROPERTIES

REQUEST_SET_LOCAL_HOST_PROPERTIES

Input buffer length

Output buffer

Parameters->Others.Arguments1 points to the IRB structure passed as input. As part of completing the request, the bus driver fills in certain members of the u member with information for the driver. The returned information is documented below with each request.

Output buffer length

Input/output buffer

Input/output buffer length

Status block

The information the bus driver returns in the I/O Status Block is documented below with each request.
