New device in MacBook Pro, yet unsupported?

New device in MacBook Pro, yet unsupported?

[Christian Schäfer]

Hi there,

I've got here a recent 13" MacBook Pro (8,1), running Ubuntu on it 
(natty). The wireless device seems to be currently unsupported by the 
b43 driver (as of kernel 2.6.38). It seems to be a bcm4331, lspci -vn 
gives the following:

03:00.0 0280: 14e4:4331 (rev 02)
     Subsystem: 106b:00d6
     Flags: bus master, fast devsel, latency 0, IRQ 11
     Memory at a0600000 (64-bit, non-prefetchable) [size=16K]
     Capabilities: [40] Power Management version 3
     Capabilities: [58] Vendor Specific Information: Len=78 <?>
     Capabilities: [48] MSI: Enable- Count=1/1 Maskable- 64bit+
     Capabilities: [d0] Express Endpoint, MSI 00
     Capabilities: [100] Advanced Error Reporting
     Capabilities: [13c] Virtual Channel
     Capabilities: [160] Device Serial Number 83-0e-47-ff-ff-36-e0-f8
     Capabilities: [16c] Power Budgeting <?>

To my current knowledge, the only way to get it working is by means of 
ndiswrapper. Are there any plans already to get this device supported 
natively? Please let me know if you need further information regarding 
the device.

Thanks,
Chris

What about

modprobe b43
dmesg | grep b43
?

This is new card without real entry in pciid, someone just typed some
dumb BCM4331 in http://pci-ids.ucw.cz/read/PC/14e4/4331

Please, provide also dmesg | grep ssb.

This can be AI card, not ssb.

modprobe b43
dmesg | grep b43
dmesg | grep ssb

returns nothing. The modprobe however produces the following:

This doesn't seem to be very fruitful either:

brcm80211: module is from the staging directory, the quality is unknown, 
you have been warned.

btw, uname -r gives:
2.6.38-7-generic

Perhaps support for the device is included in recent development kernels?

BCM4331 seems to be correct:

<http://lxr.linux.no/#linux+v2.6.38/drivers/staging/brcm80211/include/bcmdevs.h#L53>:

#define BCM4331_D11N_ID         0x4331  /* 4331 802.11n dualband id */

Since this is a three stream device, this is most likely an AI card.
So if any driver might support it, then it's brcm80211 from staging.

Any chance you can see how it's labeled? Is that possible to open
MacBook's slot to see this wifi card?

I mean something like BCM943....

I could not find you card on ebay.

I fear I cannot be of any help with this. The MacBook is from my 
employer and has a warranty seal on its back, which I'm not willing to 
break.
Perhaps remote access to my machine could help you? Let me know.

Not right now, but in future, I think I could support it this way. We
need to introduce support for AI first. Maybe before that 4331 cards
will appear on ebays? I'll ping you when support for AI is done :)

Hi Rafa?,

I compiled it into my 2.6.38.2 kernel and booted it. When I modprobe'd
it, I get nothing in dmesg.

Anything else I can try?

cheers,

Ah, sorry.

Can you modify axi_pci_bridge_tbl in host_pci.c on you own, adding
entry for your PCI ID?

If lspci -nn gives you 14e4:4331, try adding:
{ PCI_DEVICE(PCI_VENDOR_ID_BROADCOM, 0x4331) },
(which exuals to:
{ PCI_DEVICE(0x14e4, 0x4331) },
).

The brcm80211 driver seems to have lots of references to 4331, although
it doesn't include 0x4331 in its PCI device table. Might be interesting
just to load it and make it bind to the device.

I just bought a new MBP, and am stuck with one of these. Who wants it,
if it isn't currently working?

And what can I use in its place? I don't recognise the form factor at

It does not include the most important one: support for the HT PHY.

Were you able to find Windows driver for this card? The one you could
use with ndiswrapper?

I'm interested in playing with such a card, if Windows driver exists.

I've read a little about this card on Ubuntu forum. It seems to be
problematic to be used with ndiswrapper:
1) Standard Windows driver uses NDIS 6 API, which is not supported by
ndiswrapper
2) 64-bit Windows driver [0] can be used with ndiswrapper but causes
instabilities after some time of using

I've asked for tests of mmiotracer and ndiswrapper on Ubuntu forum [1] [2].

We can at least see what does Windows driver does for this card. How
much does it differ from N-PHY, etc.

I can do that but it will probably take a while; I may just use the box
with wired and Bluetooth networking for now, or not use it at all until
I'm not quite so snowed under with other things.

If you send me a SSH public key I can give you root access on the box
over the wired connection and you can play with it yourself, which might
be a lot faster all round?

If you are using Ubuntu David, you can get the mmio trace without
recompiling the kernel.
Just do

echo mmiotrace > /sys/kernel/debug/tracing/current_tracer
cat /sys/kernel/debug/tracing/trace_pipe > /tmp/dump.txt &

echo "Modprobe start" > /sys/kernel/debug/tracing/trace_marker
modprobe ndiswrapper

Hi - I just stumbled upon this thread while looking around for support
for the new bcm4331.

Maybe this is some help - it's a photo of the wireless chip from the
iFixIt teardown of the new Macbook Pro

http://guide-images.ifixit.net/igi/MIYRQcks54DunO3k.huge

I'm curious about how much work is involved with supporting a new chip
like this?

Interesting, this is card like noone other seen earlier. If there
won't be any other BCM4331 cards available for mini PCIe, it may be
harder to support them. The only solution (except buying MacBook)
seems to be SSH-ing to someone's machine. Or finding a proper adapter
for this kind of slot.

The amount of work mostly depends on used PHY and radio on this card.
This should be possible soon, when bcmai/whatever-name will be ready.

This seems to be the same situation as in case of Andy's machine. We
don't have any reference driver so I'll be hard to implement support
for this card.

Possible solutions I can see:
1) Wait for wl to support BCM4331
2) Try to use ndiswrapper and MMIO trace it's operations. Didn't try
it ever, not sure how much is this possible.
