I'm not familiar with eventfd. Do you know why eventfd causes EBUSY in io-uring? @DXist

Is it because we closed the fd but not cancelled the read op?

DXist commented 1 year ago

Haven't used it yet.

Do you have full completion queue when you try to submit? Do you read in blocking way?

There is a relevant issue in monoio

Poller::post is removed because it is not consistent between platforms. A new type Event is added, providing functionality to wake up driver. Event uses eventfd for io-uring, and calls PostQueuedCompletionStatus on Windows.

I think we could move RefCells into runtime and wrap Runtime::driver field.

I'll try that.
