2019-05-18io_uring.h: sync with kernelJens Axboe
Add sync_range_file opcode and related fields, and the io_uring_register(2) commands for eventfd registration. Signed-off-by: Jens Axboe <axboe@kernel.dk>
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>
2019-04-10test/fsync: update for IOSQE_IO_DRAIN approachJens Axboe
I generalized the barrier flag to be applicable to all commands, so let's drop the fsync special flag. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-04-06Add barrier fsync test caseJens Axboe
Also changes the fsync prep helper to require passing in the actual flag, not just a boolean for fsync vs fdatasync. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-03-19Remove IOCQE_FLAG_CACHEHITJens Axboe
This cache hint has been removed from the io_uring series, as there's some hesitation to leak this information to userspace. Remove it from the header file and the man page. We can always re-introduce it later, if we get some variant of this included. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-02-10Sync io_uring.h with the kernelJens Axboe
Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-31src/io_uring.h: sync with kernel headerJens Axboe
Just a removal of the IORING_MAX_ENTRIES user visible define. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-29Update kernel io_uring headerJens Axboe
- struct io_uring_params changed (u16 -> u32 for sq options) - Use unsigned for the flag types Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-18Switch to IORING_OP_POLL_ADD/REMOVEJens Axboe

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>
