NAME

efadv_query_qp_wqs - Query EFA specific Queue Pair work queue attributes

SYNOPSIS

#include <infiniband/efadv.h>
int efadv_query_qp_wqs(struct ibv_qp *ibvqp, struct efadv_wq_attr *sq_attr,
                       struct efadv_wq_attr *rq_attr, uint32_t inlen);

DESCRIPTION

efadv_query_qp_wqs() queries device-specific Queue Pair work queue attributes.

Compatibility is handled using the comp_mask and inlen fields.

struct efadv_wq_attr {
    uint64_t comp_mask;
    uint8_t *buffer;
    uint32_t entry_size;
    uint32_t num_entries;
    uint32_t *doorbell;
    uint32_t max_batch;
    uint8_t reserved[4];
};

inlen: In: Size of struct efadv_wq_attr.
comp_mask: Compatibility mask.
buffer: Queue buffer.
entry_size: Size of each entry in the queue.
num_entries: Maximal number of entries in the queue.
doorbell: Queue doorbell.
max_batch: Maximum batch size for queue submissions.
