IO_URING_BUFFER_GROUP_ID
If try to use a buffer ring when submitting recv / read / readvIoUringIoOps. If it is set to-1, no buffer ring will be used. Be aware that you can only change the group before the channel is registered.Check man io_uring_setup_buf_ring and this LWN article for more details.
-
IO_URING_WRITE_ZERO_COPY_THRESHOLD
The threshold for zero-copy write (send_zc and sendmsg_zc). If it is set to-1, then this function will be disabled.If the locked memory limit is too low you will observe -ENOMEM and writes will be failed. This is a clear sign that you should increase the locked memory limit via
ulimit -l.Check man io_uring_enter for more details.
