Имя (Name)
rdma_create_srq - Allocate a shared receive queue.
Синопсис (Synopsis)
#include <rdma/rdma_verbs.h>
int rdma_create_srq (struct rdma_cm_id *id, struct ibv_pd *pd,
struct ibv_srq_init_attr *attr);
Аргументы (Arguments)
id RDMA identifier.
pd Optional protection domain for the SRQ.
attr Initial SRQ attributes.
Описание (Description)
Allocate a SRQ associated with the specified rdma_cm_id.
Возвращаемое значение (Return value)
Returns 0 on success, or -1 on error. If an error occurs, errno
will be set to indicate the failure reason.
Примечание (Note)
The rdma_cm_id must be bound to a local RDMA device before
calling this function, and the protection domain, if provided,
must be for that same device. After being allocated, the SRQ
will be ready to handle posting of receives.
If a protection domain is not given - pd parameter is NULL - then
the rdma_cm_id will be created using a default protection domain.
One default protection domain is allocated per RDMA device.
The initial SRQ attributes are specified by the attr parameter.
The ext.xrc.cq fields in the ibv_srq_init_attr is optional. If a
completion queue is not specified for an XRC SRQ, then a CQ will
be allocated by the rdma_cm for the SRQ, along with corresponding
completion channels. Completion channels and CQ data created by
the rdma_cm are exposed to the user through the rdma_cm_id
structure.
The actual capabilities and properties of the created SRQ will be
returned to the user through the attr parameter. An rdma_cm_id
may only be associated with a single SRQ.
