Field Documentation

recv_control

int( * vmbus_channel_operations::recv_control) (struct vmbus_device *vmdev, uint64_t xid, const void *data, size_t len)

Handle received control packet.

Parameters

vmdev	VMBus device
xid	Transaction ID
data	Data
len	Length of data

Return values

rc	Return status code

Definition at line 407 of file vmbus.h.

recv_data

int( * vmbus_channel_operations::recv_data) (struct vmbus_device *vmdev, uint64_t xid, const void *data, size_t len, struct list_head *list)

Handle received data packet.

Parameters

vmdev	VMBus device
xid	Transaction ID
data	Data
len	Length of data
list	List of I/O buffers

Return values

rc	Return status code

This function takes ownership of the I/O buffer. It should eventually call vmbus_send_completion() to indicate to the host that the buffer can be reused.

Parameters

vmdev	VMBus device
xid	Transaction ID
data	Data
len	Length of data

Return values

rc	Return status code

recv_cancellation

int( * vmbus_channel_operations::recv_cancellation) (struct vmbus_device *vmdev, uint64_t xid)

Handle received cancellation packet.

Parameters

vmdev	VMBus device
xid	Transaction ID

Return values

rc	Return status code
