[openib-general] Get Table Records for SA Attribute ID ?

[Takshak C.]

Hi,

I m trying to get the table records for SA attribute ID in following way. 
But, I m not getting a single record, could anyone comment on the problem. 

1. I have created saMadFormat structure described in the specification as below:

struct saMadFormat
{

    uint8_t base_version ;
    uint8_t mgmt_class ;
    uint8_t class_version ;
    uint8_t sa_method ;
    uint16_t    status ;
    uint16_t    not_used ;
    uint64_t    tid ;
    uint16_t    attr_id ;
    uint16_t    resv ;
    uint32_t    attr_mod ;
    uint64_t    sa_key;
    uint64_t    sm_key ;
    uint32_t    seg_num ;
    uint32_t    payload_len ;
    uint8_t     frag_flag ;
    uint8_t edit_mod ;
    uint16_t    window ;
    uint32_t    endRID ;
    uint64_t    comp_mask ;
    uint8_t adminData[192] ;
};

2. Then I have done all the basic operations like umad_open, umad_register for the IB_SA_CLASS 
   and umad_open_port etc successfully.

3. struct saMadFormat *saQuery = (struct saMadFormat*)(umad_get_mad(umad));
   memset(saQuery, 0, sizeof(*saQuery));

   saQuery->base_version = 1;
   saQuery->mgmt_class = IB_SA_CLASS ;
   saQuery->class_version = 1 ;
   saQuery->sa_method = IB_MAD_METHOD_GET_TABLE ;
   saQuery->attr_id = IB_SA_ATTR_PATHRECORD ;
   saQuery->attr_mod = 0 ;
   saQuery->tid  = htonll(drmad_tid++);  
   saQuery->endRID = 0 ; 

   umad_set_addr(umad, lid, 1, 0, IB_DEFAULT_QP1_QKEY);
   umad_set_grh(umad, 0);
   umad_set_pkey(umad, 0xFFFF);

4. length = IB_MAD_SIZE;

  if (umad_send(portid, mad_agent, umad, length, timeout_ms, 0) < 0)
     IBPANIC("send failed");                                                                                                                     

  if (umad_recv(portid, umad, &length, -1) != mad_agent)
     IBPANIC("recv error: %s", drmad_status_str(saQuery));

                                                                                                                      

  if (!dump_char) {
      xdump(stdout, 0, saQuery->adminData, 192);
      return 0;
   }

I m expecting that, I will get the resultant data in saQuery->adminData. 
Is this correct ? If not then, how should I retrieve the table records ? 
Any Idea ? 


Thanks
