Before that in the 60s io command batching was (like most things) done by IBM: https://en.wikipedia.org/wiki/Channel_I/O#Channel_program

These days Linux supports VFIO pass-through for native IBM/360 channel programs if you happen to be running Linux on a IBM mainframe: https://docs.kernel.org/6.1/s390/vfio-ccw.html
