* Adding PCMCIA support to the kernel tree -- developers needed.

David has expressed that he'll not be able to participate in this work. He has his hands full with his day job and his role as maintainer/developer of the pcmcia-cs package. David, I would appreciate one additional layer of information that is not present in your list. Would add the names of a few representative devices for each of your bullet points? For example, for the last list item, what are the names of the major (non-CardBus) PCI-to-PCMCIA bridges? Here is David's list: > To include 16-bit PCMCIA cards in the hot plug framework would require > few driver changes; the only mandatory changes would be in how drivers > register themselves and are hooked up with appropriate devices: > > -- Make up pcmcia_device_id and pcmcia_driver types, and write new > register/unregister calls to parallel PCI and USB drivers.

Anyone willing to sign up for some of this effort?

I'll convert all the network drivers once a design is agreed upon.

Would you write up a proposal for this design that we could work from to come to a agreed design? You are probably the best person to start this process. Thanks!

I'll see whether David has time to update this page with a bit more detailed explanations of the problems. Some of the items are pretty vague. For example, the Asix AX88190 chipset, which has several serious bugs and incompatibilities that render the regular pcnet_cs driver unusable It would be nice to know exactly what those bugs and incompatibilities are. :-) Anyhow, I hope this helps, Miles - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/ ^ permalink raw reply [flat|nested] 5+ messages in thread
