If no `--with-dpdk` +option is specified to configure, the SPDK build system will automatically build a +known-good configuration of DPDK with the minimal options enabled. See the Building +section of README.md for more information. + +A [Vagrant](https://www.vagrantup.com/) setup has been added to make it easier to +develop and use SPDK on systems without suitable NVMe hardware. See the Vagrant +section of README.md for more information. + +### NVMe driver + +The NVMe driver has been updated to support recent Intel SSDs, including the Intel® +Optane™ SSD DC P4800X series. + +A workaround has been added for devices that failed to recognize register writes +during controller reset. + +The NVMe driver now allocates request tracking objects on a per-queue basis. The +number of requests allowed on an I/O queue may be set during `spdk_nvme_probe()` by +modifying `io_queue_requests` in the opts structure. + +The SPDK NVMe `fio_plugin` has been updated to support multiple threads (`numjobs`). + +### Environment Abstraction Layer + +The environment abstraction layer has been updated to include several new functions +in order to wrap additional DPDK functionality. See `include/spdk/env.h` for the +current set of functions. + ## v17.03: Blobstore and userspace vhost-scsi target ### Blobstore and BlobFS
