Here is a quick spec: SMA (for HCA device) Get NodeInfo Get NodeDescription Get/Set PortInfo Get/Set P_KeyTable (OpenSM only currently gets the P_KeyTable) Get/Set SLtoVLMappingTable (OpenSM does not get or set the SLtoVLMappingTable currently) Get/Set VLArbitrationTable if supported in IB device (OpenSM does not currently get or set VLArbitrationTable) Get/Set GUIDInfo (OpenSM does not get or set GUIDInfo currently) The bulk of the work is in PortInfo support. Also, you might want to implement PMA as well: Get/Set PortCounters Get/Set PortSamplesControl Get PortSamplesResult Get ClassPortInfo perquery only uses PortCounters. -- Hal _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
