2019-08-30examples/io_uring-cp: handle io_uring_peek_cqe() -EAGAINJens Axboe

2019-07-24src/Makefile: keep private headers in <liburing/*.h>Stefan Hajnoczi
It is not possible to install barrier.h and compat.h into the top-level /usr/include directly since they are likely to conflict with other software. io_uring.h could be confused with the system's kernel header file. Put liburing headers into <liburing/*.h> so there is no chance of conflicts or confusion. Existing applications continue to build successfully since the location of <liburing.h> is unchanged. In-tree examples and tests require modification because src/liburing.h is moved to src/include/liburing.h.

2019-07-08Makefiles: Support specifying CFLAGS on the command lineBart Van Assche
This patch makes the liburing build work as expected for e.g. the following command: make CFLAGS=-m32 and avoids that the build fails as follows for the above command: make[1]: Entering directory 'liburing/test' cc -m32 -o poll poll.c -luring /usr/bin/ld: cannot find -luring collect2: error: ld returned 1 exit status Makefile:18: recipe for target 'poll' failed make[1]: *** [poll] Error 1 make[1]: Leaving directory 'software/liburing/test' Makefile:12: recipe for target 'all' failed make: *** [all] Error 2 Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-06-13example/io_uring-test.c: Fix iovecs incrementStephen Bates
This example misses an increment though the iovecs array. This causes the same buffer to be filled from the block device every time. It would be good to fix this since it is one of the first examples a new-comer to io_uring is exposed too.

2019-05-22examples/io_uring-cp: fix a NULL pointer dereferencezhangliguang
In case malloc fails, the fix returns NULL to avoid NULL pointer dereference. Signed-off-by: zhangliguang <zhangliguang@linux.alibaba.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-05-15examples/link-cp: improve memory useJens Axboe
Put the data at the end so we don't have to offset the actual buffer. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-05-15examples/link-cp: improvementsJens Axboe
Add short read requeue and abort on error. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-05-14examples/link-cp: fix a few issuesJens Axboe
Still need to handle broken chains, must resubmit those. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-05-14Add chain failure handling test caseJens Axboe

2019-05-13Add link SQE supportJens Axboe
Just a basic test case that does various forms of linked nops, and a sample bare bones copy program using linked reads and writes. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-04-18Rename completion helpersJens Axboe
We have io_uring_get_sqe() on the submission side, yet the completion side is named _completion. Rename as follows: io_uring_get_completion() io_uring_peek_cqe() iO_uring_wait_completion() io_uring_wait_cqe() This better tells the user what the _get variant does by calling it _peek instead, and we move to using _cqe() as the postfix instead of _completion.

2019-04-17Separate test cases from examplesJens Axboe
Also adds a runtests makefile target.
