DECLARE_RIO_SWITCH_INIT - Registers switch initialization routine : RIO vendor ID : RIO device ID : Callback that performs switch-specific initialization
Manipulating switch route tables and error management in RIO is switch specific. This registers a switch by vendor and device ID with initialization callback for setting up switch operations and (if required) hardware initialization. A &struct rio_switch_ops is initialized with pointer to the init routine and placed into a RIO-specific kernel section.
rio_create_sysfs_dev_files - create RIO specific sysfs files : device whose entries should be created
Create files when is added to sysfs.
Definition at line 250 of file rio-sysfs.c.
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.
Definition at line 1372 of file rio-scan.c.
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.
Definition at line 1269 of file rio-scan.c.
rio_get_comptag - Begin or continue searching for a RIO device by component tag : RIO component tag to match : Previous RIO device found in search, or NULL for new search
Iterates through the list of known RIO devices. If a RIO device is found with a matching , a pointer to its device structure is returned. Otherwise, NULL is returned. A new search is initiated by passing NULL to the argument. Otherwise, if is not NULL, searches continue from next device on the global list.
rio_mport_get_efb - get pointer to next extended features block : Master port to issue transaction : Indicate a local master port or remote device access : Destination ID of the device : Number of switch hops to the device : Offset of current Extended Feature block header (if 0 starts from ExtFeaturePtr)
rio_mport_get_feature - query for devices' extended features : Master port to issue transaction : Indicate a local master port or remote device access : Destination ID of the device : Number of switch hops to the device : Extended feature code
Tell if a device supports a given RapidIO capability. Returns the offset of the requested extended feature block within the device's RIO configuration space or 0 in case the device does not support it. Possible values for :
RIO_EFB_PAR_EP_ID LP/LVDS EP Devices
RIO_EFB_PAR_EP_REC_ID LP/LVDS EP Recovery Devices
RIO_EFB_PAR_EP_FREE_ID LP/LVDS EP Free Devices
RIO_EFB_SER_EP_ID LP/Serial EP Devices
RIO_EFB_SER_EP_REC_ID LP/Serial EP Recovery Devices
RIO_EFB_SER_EP_FREE_ID LP/Serial EP Free Devices
