It'll take a while to get full coverage of it, but # we're working towards it. I've also added two basic test programs to # tools/io_uring. One uses the raw interface and has support for all the # various features that io_uring supports outside of standard IO, like # fixed files, fixed IO buffers, and polled IO. The other uses the # liburing API, and is a simplified version of cp(1). # # This adds support for a new IO interface, io_uring. # # io_uring allows an application to communicate with the kernel through # two rings, the submission queue (SQ) and completion queue (CQ) ring. # This allows for very efficient handling of IOs, see the v5 posting for # some basic numbers: # # https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/ # # Outside of just efficiency, the interface is also flexible and # extendable, and allows for future use cases like the upcoming NVMe # key-value store API, networked IO, and so on. It also supports async # buffered IO, something that we've always failed to support in the # kernel. # # Outside of basic IO features, it supports async polled IO as well. # This particular feature has already been tested at Facebook months ago # for flash storage boxes, with 25-33% improvements. It makes polled IO # actually useful for real world use cases, where even basic flash sees # a nice win in terms of efficiency, latency, and performance. These # boxes were IOPS bound before, now they are not. # # This series adds three new system calls. One for setting up an # io_uring instance (io_uring_setup(2)), one for submitting/completing # IO (io_uring_enter(2)), and one for aux functions like registrating # file sets, buffers, etc (io_uring_register(2)). Through the help of # Arnd, I've coordinated the syscall numbers so merge on that front # should be painless. # # Jon did a writeup of the interface a while back, which (except for # minor details that have been tweaked) is still accurate. Find that # here: # # https://lwn.net/Articles/776703/ # # Huge thanks to Al Viro for helping getting the reference cycle code # correct, and to Jann Horn for his extensive reviews focused on both # security and bugs in general. # # There's a userspace library that provides basic functionality for # applications that don't need or want to care about how to fiddle with # the rings directly. It has helpers to allow applications to easily set # up an io_uring instance, and submit/complete IO through it without # knowing about the intricacies of the rings. It also includes man pages # (thanks to Jeff Moyer), and will continue to grow support helper # functions and features as time progresses. Find it here: # # git://git.kernel.dk/liburing # # Fio has full support for the raw interface, both in the form of an IO # engine (io_uring), but also with a small test application (t/io_uring) # that can exercise and benchmark the interface" #
