NAME
efadv_query_mr - Query EFA specific Memory Region attributes
SYNOPSIS
#include <infiniband/efadv.h>
int efadv_query_mr(struct ibv_mr *ibvmr, struct efadv_mr_attr *attr, uint32_t inlen);
DESCRIPTION
efadv_query_mr() queries device-specific Memory Region attributes.
Compatibility is handled using the comp_mask and inlen fields.
struct
efadv_mr_attr {
uint64_t comp_mask;
uint16_t ic_id_validity;
uint16_t recv_ic_id;
uint16_t rdma_read_ic_id;
uint16_t rdma_recv_ic_id;
};
|
inlen |
In: Size of struct efadv_mr_attr. |
comp_mask
Compatibility mask.
ic_id_validity
Validity mask of interconnect id fields:
EFADV_MR_ATTR_VALIDITY_RECV_IC_ID: recv_ic_id has a valid value.
EFADV_MR_ATTR_VALIDITY_RDMA_READ_IC_ID: rdma_read_ic_id has a valid value.
EFADV_MR_ATTR_VALIDITY_RDMA_RECV_IC_ID: rdma_recv_ic_id has a valid value.
recv_ic_id
Physical interconnect used by the device to reach the MR for receive operation.
rdma_read_ic_id
Physical interconnect used by the device to reach the MR for RDMA read operation.
rdma_recv_ic_id
Physical interconnect used by the device to reach the MR for RDMA write receive.
RETURN VALUE
efadv_query_mr() returns 0 on success, or the value of errno on failure (which indicates the failure reason).
