Subject: [Qemu-devel] [PATCH v3 0/8] Add support for io_uring
Date: Mon, 27 May 2019 13:33:19 +0530 [thread overview]
Message-ID: <20190527080327.10780-1-mehta.aaru20@gmail.com> (raw)
This patch series adds support for the newly developed io_uring Linux AIO
interface. Linux io_uring is faster than Linux's AIO asynchronous I/O code,
offers efficient buffered asynchronous I/O support, the ability to do I/O
without performing a system call via polled I/O, and other efficiency
enhancements. Testing it requires a host kernel (5.1+) and the liburing
library. Use the option -drive aio=io_uring to enable it.
v2:
- Fix Patchew errors
- Option now enumerates only for CONFIG_LINUX in qapi
- Removed redudant and broken code in io_uring
- io_uring now aborts on sqe leak
v3:
- Fix major errors in io_uring (sorry)
- Option now enumerates for CONFIG_LINUX_IO_URING
- pkg config support added
Aarushi Mehta (8):
configure: permit use of io_uring
qapi/block-core: add option for io_uring
block/block: add BDRV flag for io_uring
block/io_uring: implements interfaces for io_uring
stubs: add stubs for io_uring interface
util/async: add aio interfaces for io_uring
blockdev: accept io_uring as option
block/fileposix: extend to use io_uring
