- This directory includes a few programs that demonstrate how to use io_uring
- in an application. The examples are:
- io_uring-cp
- A very basic io_uring implementation of cp(1). It takes two
- arguments, copies the first argument to the second. This example
- is part of liburing, and hence uses the simplified liburing API
- for setting up an io_uring instance, submitting IO, completing IO,
- etc. The support functions in queue.c and setup.c are straight
- out of liburing.
- io_uring-bench
- Benchmark program that does random reads on a number of files. This
- app demonstrates the various features of io_uring, like fixed files,
- fixed buffers, and polled IO. There are options in the program to
- control which features to use. Arguments is the file (or files) that
- io_uring-bench should operate on. This uses the raw io_uring
- interface.
- liburing can be cloned with git here:
- git://git.kernel.dk/liburing
- and contains a number of unit tests as well for testing io_uring. It also
- comes with man pages for the three system calls.
- Fio includes an io_uring engine, you can clone fio here:
- git://git.kernel.dk/fio
