int __devinit rio_disc_mport

(

struct rio_mport *

mport

)

rio_disc_mport- Start discovery through a master port : Master port to send transactions

Starts the discovery process. If we have an active link, then wait for the signal that enumeration is complete. When enumeration completion is signaled, start recursive peer discovery. Returns %0 if discovery succeeds or %-EBUSY on failure.

int rio_enable_rx_tx_port ( struct rio_mport *  port, int  local, u16  destid, u8  hopcount, u8  port_num  )

inline

rio_enable_rx_tx_port - enable input receiver and output transmitter of given port : Master port associated with the RIO network : local=1 select local port otherwise a far device is reached : Destination ID of the device to check host bit : Number of hops to reach the target : Port (-number on switch) to enable on a far end device

Returns 0 or 1 from on General Control Command and Status Register (EXT_PTR+0x3C)

int __devinit rio_enum_mport

(

struct rio_mport *

mport

)

rio_enum_mport- Start enumeration through a master port : Master port to send transactions

Starts the enumeration process. If somebody has enumerated our master port device, then give up. If not and we have an active link, then start recursive peer enumeration. Returns %0 if enumeration succeeds or %-EBUSY if enumeration fails.
