Marvell pci wifi chips

Marvell pci wifi chips

[Alex Deucher]

Is anyone working on a driver for the marvell pci libertas chips
(8335, 8300, 8310, etc.) or know of someone who is?  I've got several
of these cards not doing anything at the moment if someone is
interested in one.  It seems there are several drivers floating
around:

- mrv8k driver (http://www.saillard.org/linux/mrv8k/)
- openbsd malo driver (http://www.openbsd.org/cgi-bin/man.cgi?query=malo)
- marvell GPL driver (http://johannes.sipsolutions.net/files/marvell.tar.bz2)

Reading through the linux-wireless archive, several people seemed to
indicate there was work going on, but I have not been able to find any
information on that other than Holger's CF libertas integration.  I
and others have asked before, but there seems to be some confusion as
to the whole libertas line and their relative compatibility.  Just
curious.

Thanks,

Alex

I think I saw discussion lately to the effect that the PCI devices are
not currently supported, and that they likely could be supported by
simply implementing a PCI front-end to the core of the libertas code.
I think Holger is the person most likely to know for sure.

I've got cards like that too -- would love for you to get them
working... :-)

Has anyone tested the marvell driver
(http://johannes.sipsolutions.net/files/marvell.tar.bz2)?  Does it
work?

Maybe the author ?!?

If you have a PCI based card with a Marvell WLAN chip, why don't=20
you try this driver and report success/failure here on the=20
mailing list?

But who'd that be? It looks like internal to some embedded systems
company IIRC.

I attempted to build the driver on 2.6.22, but I got the following
errors.  Unfortunately, I'm not too familiar with the net80211 stuff.
Anyone got any ideas?

Well, it depends if the firmware interface is similar to the 838x line.
These are fullmac chips, but I'm unsure if the 8335/8300/8310 are
anything like that.  ISTR they are more softmac-like, and therefore the
firmware interface would be quite different.  Might need a different
driver for them.

- marvell GPL driver
> (http://johannes.sipsolutions.net/files/marvell.tar.bz2)

I looked at this driver. Yes, it seems to be for a PCI Marvell 
WLAN chip.

But looking at the registers (e.g. bit definitions), this driver 
seems to have a very (!) different architecture to the 
CF/SDIO/USB based 83xx chips the libertas driver supports.


So feel free to grab this driver, push it in shape and submit it 
to the Linux kernel. It's GPL, after all :-)
