◆ _request_output_port()

virtual size_t uhd::rfnoc::source_block_ctrl_base::_request_output_port	(	const size_t	suggested_port,
		const uhd::device_addr_t &	args
	)		const

protectedvirtual

Like source_node_ctrl::_request_output_port(), but also checks if the port has an output signature.

Reimplemented from uhd::rfnoc::source_node_ctrl.

◆ configure_flow_control_out()

virtual void uhd::rfnoc::source_block_ctrl_base::configure_flow_control_out	(	const bool	enable_output,
		const bool	lossless_link,
		const size_t	buf_size_bytes,
		const size_t	pkt_limit = `0`,
		const size_t	block_port = `0`,
		const uhd::sid_t &	sid = `uhd::sid_t()`
	)

virtual

Configure flow control for outgoing streams.

In the default implementation, this just sets registers SR_FLOW_CTRL_BUF_SIZE and SR_FLOW_CTRL_ENABLE accordingly; block_port and sid are ignored.

Override this function if your block has port-specific flow control settings.

Parameters

enable_output	Enable flow control module's output. If disabled, no packets will be output regardless of flow control state.
buf_size_bytes	The size of the downstream block's input FIFO size in number of bytes. Setting this to zero disables byte based flow control. If both byte based flow control and the packet limit are set to zero, the block will then produce data as fast as it can. Warning: This can cause head-of-line blocking, and potentially lock up your device!
lossless_link	The link for the connection is lossless. Periodic sync packets will be disabled.
pkt_limit	Limit the maximum number of packets in flight. Setting this to zero disables packet limiting. Usually kept disabled except for special case connections (such as DMA) that support only a finite number of packets in flight.
block_port	Specify on which outgoing port this setting is valid.
sid	The SID for which this is valid. This is meant for cases where the outgoing block port is not sufficient to set the flow control, and as such is rarely used.

◆ get_mtu()

size_t uhd::rfnoc::source_block_ctrl_base::get_mtu ( size_t block_port = 0 ) const

Return the MTU size on a given block port.

This is necessary for setting up transports, among other things.

If the block port is not defined, it will return 0, and not throw.

Parameters

block_port The block port (0 through 15).

Returns the MTU in bytes.

◆ get_output_ports()

std::vector<size_t> uhd::rfnoc::source_block_ctrl_base::get_output_ports ( ) const

Return a list of valid output ports.

◆ get_output_signature()

stream_sig_t uhd::rfnoc::source_block_ctrl_base::get_output_signature ( size_t block_port = 0 ) const

Return the output stream signature for a given block port.

The actual signature is determined by the current configuration and the block definition file. The value returned here is calculated on-the-fly and is only valid as long as the configuration does not change.

Returns: The stream signature for port block_port

Exceptions

uhd::runtime_error if block_port is not a valid port

◆ issue_stream_cmd()

virtual void uhd::rfnoc::source_block_ctrl_base::issue_stream_cmd	(	const uhd::stream_cmd_t &	stream_cmd,
		const size_t	chan = `0`
	)

virtual

Issue a stream command for this block.

There is no guaranteed action for this command. The default implementation is to send this command to the next upstream block, or issue a warning if there is no upstream block registered.

However, implementations of block_ctrl_base might choose to do whatever seems appropriate, including throwing exceptions. This may also be true for some stream commands and not for others (i.e. STREAM_MODE_START_CONTINUOUS may be implemented, and STREAM_MODE_NUM_SAMPS_AND_DONE may be not).

This function does not check for infinite loops. Example: Say you have two blocks, which are both registered as upstream from one another. If they both use block_ctrl_base::issue_stream_cmd(), then the stream command will be passed from one block to another indefinitely. This will not happen if one the block's controller classes overrides this function and actually handles it.

◆ set_destination()

virtual void uhd::rfnoc::source_block_ctrl_base::set_destination	(	uint32_t	next_address,
		size_t	output_block_port = `0`
	)

virtual

Configures data flowing from port output_block_port to go to next_address

Parameters

next_address	Address of the downstream block
output_block_port	Port for which this is valid

In the default implementation, this will write the value in next_address to register SR_NEXT_DST of this blocks settings bus. The value will also have bit 16 set to 1, since some blocks require this to respect this value.

The documentation for this class was generated from the following file:

include/uhd/rfnoc/source_block_ctrl_base.hpp

stream_cmd	The stream command.
chan	Channel for which this command is meant (data shall be produced on this channel).
