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 |
