Daniel Verkamp e2d3cc6502 nvme: replace rte_memcpy with specialized function
Use the knowledge that both the source and destination of
nvme_copy_command() are aligned to emit the aligned variants of the
SSE2/AVX mov instructions.

Compiling

First, clone the fio source repository from http://github.com/axboe/fio

git clone http://github.com/axboe/fio

Then check out the fio 2.8 tag

cd fio && git checkout fio-2.8

Finally, compile the code with

./configure && make

Next, edit the CONFIG file located in the root of the SPDK repository and set CONFIG_FIO_PLUGIN to y and FIO_SOURCE_DIR to the location of the fio repository that was just created.

Further, you'll need to build DPDK with -fPIC set. You can do this by modifying your DPDK config file (i.e. config/defconfig_x86_64-native-linuxapp-gcc) to include the line

EXTRA_CFLAGS=-fPIC

At this point, build SPDK as per normal. The fio plugin will be placed in the same directory as this README.

Usage

To use the SPDK fio plugin with fio, simply set the following in the fio configuration file (see example_config.fio in the same directory as this README).

ioengine=<path to fio_plugin binary>

To select NVMe devices, you simply pass an identifier as the filename in the format

domain.bus.slot.func/namespace

Remember that NVMe namespaces start at 1, not 0! Also, the notation uses '.' throughout, not ':'. For example - 0000.04.00.0/1.
