  • 72f04da48   tools/io_uring: fix compile breakage ... Browse Code »

    It would seem none of the kernel continuous integration does this:
    $ cd tools/io_uring
    $ make

    Otherwise it may have noticed:
    cc -Wall -Wextra -g -D_GNU_SOURCE -c -o io_uring-bench.o
    io_uring-bench.c
    io_uring-bench.c:133:12: error: static declaration of ‘gettid’
    follows non-static declaration
    133 | static int gettid(void)
    | ^~~~~~
    In file included from /usr/include/unistd.h:1170,
    from io_uring-bench.c:27:
    /usr/include/x86_64-linux-gnu/bits/unistd_ext.h:34:16: note:
    previous declaration of ‘gettid’ was here
    34 | extern __pid_t gettid (void) __THROW;
    | ^~~~~~
    make: *** [: io_uring-bench.o] Error 1

    The problem on Ubuntu 20.04 (with lk 5.9.0-rc5) is that unistd.h
    already defines gettid(). So prefix the local definition with
    "lk_".

  • 5769a351b   io_uring: change the poll type to be 32-bits ... Browse Code »

    poll events should be 32-bits to cover EPOLLEXCLUSIVE.

    Explicit word-swap the poll32_events for big endian to make sure the ABI
    is not changed. We call this feature IORING_FEAT_POLL_32BITS,
    applications who want to use EPOLLEXCLUSIVE should check the feature bit
    first.

  • 004d564f9   tools/io_uring: sync with liburing ... Browse Code »

    Various fixes and changes have been applied to liburing since we
    copied some select bits to the kernel testing/examples part, sync
    up with liburing to get those changes.

    Most notable is the change that split the CQE reading into the peek
    and seen event, instead of being just a single function. Also fixes
    an unsigned wrap issue in io_uring_submit(), leak of 'fd' in setup
    if we fail, and various other little issues.

  • 21b4aa5d2   io_uring: add a few test tools ... Browse Code »

    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.
