2019-02-28Add read/write fixed prep supportJens Axboe
Also unify the setup, all the read/write variants can use the same helper. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-02-08test/fsync: add simple fsync testerJens Axboe
Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-02-08add io_uring_queue_mmapJeff Moyer
io_uring_queue_init does not allow the caller to specify sq_thread_cpu or sq_thread_idle. Users that want to specify those parameters need to call io_uring_setup(2) themselves. Add a helper so that they don't also have to hand-craft the code to map the submission and completion queues, and setup the sqe ring. This allows those applications to still make use of io_uring_submit and get/wait_completion. Signed-off-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-02-08io_uring_enter: don't expose sigset_size argumentJens Axboe
Applications should not need to care about this, we can pass it in ourselves. Once the libc support is there, we won't expose this parameter either. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-02-08Add sigmask parameter to io_uring_enterJeff Moyer
Update liburing and io_uring_enter.2 to match the kernel. Signed-off-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-02-05io_uring_register takes 4 argsJeff Moyer
Signed-off-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-18Switch to IORING_OP_POLL_ADD/REMOVEJens Axboe
Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-17liburing: ensure prep helpers actually set iovec countJens Axboe
Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-17Add sqe prep helpersJens Axboe
Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-15Add configure scriptJens Axboe
Some older installs don't have __kernel_rwf_t in linux/fs.h, so add a check for that. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-10io_queue_init: pass in flags, not io_uring_paramsJens Axboe
We don't need any of the information in there in the caller, and this makes it harder to abuse as we don't require the caller to have memset() the struct first. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-10Update to newer APIJens Axboe
- Fixed buffers are now available through io_uring_register() - Various thread/wq options are now dead and automatic instead - sqe->index is now sqe->buf_index - Fixed buffers require flag, not separate opcode Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-10Update APIJens Axboe
- io_uring_sqe added a data field that's passed back at completion - io_uring_sqe added an index field, for fixed buffer locations - io_uring_setup(2) system call added a 'nr_iovecs' field Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-09Update to newer APIJens Axboe

2019-01-08liburing: include the ring fd in the io_uringJens Axboe
No point in keeping these separate. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-08Change API to provide io_uring struct abstractionJens Axboe
This is cleaner than having the app juggle an SQ and CQ ring, just wrap them in struct io_uring and have the API always take that. This means the app doesn't need to worry about the different types of rings, and that we only need to pass in one argument for setup/teardown. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-08liburing: add io_uring_iocb_from_ev() helperJens Axboe
Returns the iocb associated with a completion event. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-08Add option for getting a completion without waitingJens Axboe
This now exposes two helpers: io_uring_get_completion() Return a completion, if we have one (or more) available in the ring io_uring_wait_completion() Return a completion, waiting for it if necessary Signed-off-by: Jens Axboe <axboe@kernel.dk>
