Hello. I am interested in implementing Uniform Driver Interface (UDI) on PDOS (http://pdos.sourceforge.net). Currently PDOS is using BIOS instead of drivers and I would like to change that by implementing UDI.
PDOS is still in early development, so anything can be changed to accommodate UDI.
I read UDI core specification, physical IO specification, IA ABI specification and system bus and PCI bus specifications and created udi.h, udi_physio.h, udi_sysbus.h and udi_pci.h (https://sourceforge.net/p/pdos/gitcode/ ... di/include). I am not sure what are the next steps required to implement UDI and the reference implementation and specifications are not very helpful.
Can somebody explain step-by-step what is needed to implement UDI on a new x86 OS?
Thanks.
