FireWire chip on PISMO?

FireWire chip on PISMO?

[Albrecht Dre_]

Does anyone know where I could find information about the FireWire controller
chip which is used in the Apple PISMO Powerbook?  lspci tells me that it was
made by Apple, device id 0x0018, and I think this one is not (yet) supported by
the FireWire-for-Linux stuff.

Thanks, Albrecht.

It's a standard OHCI chip, probably repackaged in a custom ASIC, but it
works with the same drivers as all the other OHCI devices.  You should
only need to add an extra ID in your supported device lists for the linux
drivers to support it.  If the driver doesn't work out of the box, there's
a driver bug in general.  :-)

This first "quick hack" to the ohci driver lead to a kernel panic...  Sigh!
I'll have to try in more depth...

Thanks anyway, Albrecht.

It's a OHCI FireWire controller inside of Apple's Uni-N custom ASIC.
Since it's OHCI, support should theoretically be a matter of just
letting the FireWire code know about its device ID (if it doesn't
already).
