Hello, I was trying to increase the queue depth of the qpairs in my application and I saw that passing options to the spdk_nvme_ctrlr_alloc_io_qpair function had no effect. Digging into the spdk source, the function nvme_transport_ctrlr_create_io_qpair, in the file nvme_ctrlr_ut.c does the following: struct spdk_nvme_qpair *qpair; qpair = calloc(1, sizeof(*qpair)); [...] qpair->ctrlr = ctrlr; qpair->id = qid; qpair->qprio = opts->qprio; return qpair; The rest of the values of the struct opts are ignored, or am I missing something?
