Re: [PATCH 2/2] nvmet-rdma: implement get_queue_size controller op

Limit the maximal queue size for RDMA controllers. Today, the target reports a limit of 1024 and this limit isn't valid for some of the RDMA based controllers. For now, limit RDMA transport to 128 entries (the default queue depth configured for Linux NVMeoF host fabric drivers). Future general solution should use RDMA/core API to calculate this size according to device capabilities and number of WRs needed per NVMe IO request.
What is preventing you from doing that today? You have the device, can't you check attr.max_qp_wr? _______________________________________________ Linux-nvme mailing list Linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
