Yes. I want to add an iosize parameter to the dev_desc structure in -current. This is needed so address ranges can be properly allocated and aligned (the size of the address range determines its alignment requirements). : However, perhaps it makes more sense to have a more complete syntax for : supplying CIS overrides? In the long run, yes. This will be needed in the next generation as well. For example, some Libretto floppy cards have bad CIS information, and the Linux driver compensates by instructing users of these cards to use the CIS override feature of the linux's pccard system. For most people it isn't needed, but for those unlucky enough to have early serial numbered floppy cards that's the only way to make them work. I'm not sure how much sense it makes now, but if a good implementation can be constructed, I'll not oppose it. : I guess it depends a lot on how many of these overrides are likely to : be needed. I don't know. I believe that the linux card stff gives one the ability to add/delete/replace any CIS to compensate for broken cards.
