I know the IRQ and the Port - address-number of my MIDI
- onboard controller.
Are these information enough to write a short MIDI-driver for alsa ? If yes,
normally, this is very, very far from the information you need. the
only exception would be if it was a native MPU401 or serial MIDI
device, in which case ALSA already drivers for it.
writing a device driver means knowing which registers and memory
locations to set, reset, read, write, and when to do it.
