cvmx_helper_link_info_t __cvmx_helper_board_link_get

(

int

ipd_port

)

This function is the board specific method of determining an ethernet ports link speed. Most Octeon boards have Marvell PHYs and are handled by the fall through case. This function must be updated for boards that don't have the normal Marvell PHYs.

This function must be modified for every new Octeon board. Internally it uses switch statements based on the cvmx_sysinfo data to determine board types and revisions. It relies on the fact that every Octeon board receives a unique board type enumeration from the bootloader.

: IPD input port associated with the port we want to get link status for.

Returns The ports link status. If the link isn't fully resolved, this must return zero.

int cvmx_helper_board_get_mii_address

(

int

ipd_port

)

Return the MII PHY address associated with the given IPD port. A result of -1 means there isn't a MII capable PHY connected to this port. On chips supporting multiple MII busses the bus number is encoded in bits <15:8>.

This function must be modified for every new Octeon board. Internally it uses switch statements based on the cvmx_sysinfo data to determine board types and revisions. It replies on the fact that every Octeon board receives a unique board type enumeration from the bootloader.

: Octeon IPD port to get the MII address for.

Returns MII PHY address and bus number or -1.

int cvmx_helper_board_link_set_phy	(	int	phy_addr,
		cvmx_helper_board_set_phy_link_flags_types_t	link_flags,
		cvmx_helper_link_info_t	link_info
	)

This function as a board specific method of changing the PHY speed, duplex, and auto-negotiation. This programs the PHY and not Octeon. This can be used to force Octeon's links to specific settings.

: The address of the PHY to program : Non zero if you want to enable auto-negotiation. : Link speed to program. If the speed is zero and auto-negotiation is enabled, all possible negotiation speeds are advertised.

Returns Zero on success, negative on failure

Variable Documentation

cvmx_helper_link_info_t(* cvmx_override_board_link_get)(int ipd_port)

Initial value:

=
    NULL

cvmx_override_board_link_get(int ipd_port) is a function pointer. It is meant to allow customization of the process of talking to a PHY to determine link speed. It is called every time a PHY must be polled for link status. Users should set this pointer to a function before calling any cvmx-helper operations.
