This is only a very simple and incomplete version of the API.
Only API for now is direct PCI I/O.
The PCI API is rather ... complicated. Firstly, because of just how versatile the read/write I/O Access methods are. And secondly, because the whole topic is complicated.
Instead of packing all the variants into read() and write(), I instead unpacked each variant as their own prefixed method.
write(),fill_write(),fifo_write(), etc.Checklist
