This adds two test programs in tools/io_uring/ that demonstrate both the raw io_uring API (and all features) through a small benchmark app, io_uring-bench, and the liburing exposed API in a simplified cp(1) implementation through io_uring-cp. Signed-off-by: Jens Axboe <axboe@kernel.dk>

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:
