Definition at line 41 of file cvmx-helper.h.
Configure a port for internal and/or external loopback. Internal loopback causes packets sent by the port to be received by Octeon. External loopback causes packets received from the wire to sent out again.
: IPD/PKO port to loopback. : Non zero if you want internal loopback : Non zero if you want external loopback
Returns Zero on success, negative on failure.
Definition at line 1077 of file cvmx-helper.c.
Return the number of interfaces the chip has. Each interface may have multiple ports. Most chips support two interfaces, but the CNX0XX and CNX1XX are exceptions. These only support one interface.
Returns Number of interfaces on chip
Definition at line 84 of file cvmx-helper.c.
Initialize the PIP, IPD, and PKO hardware to support simple priority based queues for the ethernet ports. Each port is configured with a number of priority queues based on CVMX_PKO_QUEUES_PER_PORT_* where each queue is lower priority than the previous.
Returns Zero on success, non-zero on failure

Does core local initialization for packet io

This function enables the IPD and also enables the packet interfaces. The packet interfaces (RGMII and SPI) must be enabled after the IPD. This should be called by the user program after any additional IPD configuration changes are made if CVMX_HELPER_ENABLE_IPD is not set in the executive-config.h file.
Returns 0 on success -1 on failure
Called after all internal packet IO paths are setup. This function enables IPD/PIP and begins packet input and output.
Returns Zero on success, negative on failure

| cvmx_helper_link_info_t cvmx_helper_link_autoconf | ( | int | ipd_port | ) |
Auto configure an IPD/PKO port link state and speed. This function basically does the equivalent of: cvmx_helper_link_set(ipd_port, cvmx_helper_link_get(ipd_port));
: IPD/PKO port to auto configure
Returns Link state after configure
Definition at line 926 of file cvmx-helper.c.
| cvmx_helper_link_info_t cvmx_helper_link_get | ( | int | ipd_port | ) |
Return the link state of an IPD/PKO port as returned by auto negotiation. The result of this function may not match Octeon's link config if auto negotiation has changed since the last call to cvmx_helper_link_set().
: IPD/PKO port to query
Returns Link state

| int cvmx_helper_link_set | ( | int | ipd_port, |
| cvmx_helper_link_info_t | link_info | ||
| ) |
Configure an IPD/PKO port for the specified link state. This function does not influence auto negotiation at the PHY level. The passed link state must always match the link state returned by cvmx_helper_link_get(). It is normally best to use cvmx_helper_link_autoconf() instead.
: IPD/PKO port to configure : The new link state
Returns Zero on success, negative on failure

cvmx_override_ipd_port_setup(int ipd_port) is a function pointer. It is meant to allow customization of the IPD port setup before packet input/output comes online. It is called after cvmx-helper does the default IPD configuration, but before IPD is enabled. Users should set this pointer to a function before calling any cvmx-helper operations.

cvmx_override_pko_queue_priority(int ipd_port, uint64_t priorities[16]) is a function pointer. It is meant to allow customization of the PKO queue priorities based on the port number. Users should set this pointer to a function before calling any cvmx-helper operations.
