My suggestion has always been to give Linux what it wants. For memory,
this means providing the E820 table, and for PCI $PIR, this means
providing the PCI IRQ routing table... This is the cost of having your
own data table, etc. -- you have to modify all the software you are
working with just to read the data table.
Why not just provide the tables existing software is already tested and
proven to work with?
IIRC Eric disagrees, preferring a custom table...
