How io_uring and eBPF Will Revolutionize Programming in Linux
Ah the funny things we resad about in 2020.In 1985... yes I said 1985, the Amiga did all I/O through sending and receiving messages. You queued a message to the port of the device / disk you wanted, when the I/O was complete you received a reply on your port.The same message port system was used to receive UI messages. And filesystems, on top of drive system, were also using port/messages. So did serial devices. Everything.Simple, asynchronous by nature.As a matter of fact, it was even more elegant than this. Devices were just DLL with a message port.
