Detailed Description

Header for commands to interact with the simulator outside of normal device interface.

Function Documentation

ec_host_cmd_backend_sim_data_received()

int ec_host_cmd_backend_sim_data_received	(	const uint8_t *	buffer,
		size_t	len
	)

Simulate receiving data from host as passed in to this function.

Calling this function simulates that data was sent from the host to the DUT.

Parameters

buffer	The buffer that contains the data to receive.
len	The number of bytes that are received from the above buffer.

Return values

0	if successful
-ENOMEM	if len is greater than the RX buffer size.
-EBUSY	if the host command framework is busy with another request.

ec_host_cmd_backend_sim_install_send_cb()

void ec_host_cmd_backend_sim_install_send_cb	(	ec_host_cmd_backend_api_send	cb,
		struct ec_host_cmd_tx_buf **	tx_buf
	)

Install callback for when this device would sends data to host.

When this host command simulator device should send data to the host, it will call the the callback parameter provided by this function. Note that only one callback may be installed at a time. Calling this a second time will override the first callback installation.

Parameters

cb	Callback that is called when device would send data to host.
tx_buf	Pointer of a pointer to the tx buf structure where data will be sent.
