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-linux-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.
