I don't think we will ever want to extract SPROM info to something
else. Can't imageine such a situation right now.

Of course it may happen some new requirement will appear in the
future. But it's hard to predict it right now. And we never know what
macro will handle that future requirement. Oh, and we always can
modify existing macro or add new one :) Fortunately it's not any kind
of API :)

Re: Some confusion over which 'b43' v5.10.x firmware I should be using

Hi Larry

Thanks for the prompt reply.  Based on your response to my question, I decided to take the plunge and upgrade my "b43-firmware" package. My main reason for doing so was because it could positively impact some of the newer 'b43' devices.

A user of this package has informed me that he's run into problems using the new (v5.10.144.3) firmware on his BCM4312 device.  After viewing the output he's supplied, can you explain to me what's going on and how we can overcome this issue?

I have problems with todays upgrade.
I have a BCM4312 (http://ompldr.org/vYzFneg/wlan), which works the last version, but not with todays upgrade.
Kernel-Log with 5.10.56.27.3-2 => http://ompldr.org/vYzFoMg/5.10.56.27.3-2
Kernel-Log with 5.10.144.3-1 => http://ompldr.org/vYzFoNQ/5.10.144.3-1

poor performance with BCM4331 and 3.2

Hello,
 I've been having issues with getting the b43 driver to work reliably
in Ubuntu 11.10 on a MacbookPro 8,1.  The problem is that the driver
seems to be losing connection very often, especially when I have
multiple programs hitting the net. (s.a. Spotify, Firefox and Chrome),
sometimes even causing kernel panics( pre kernel 3.2 final). I'm now
using kernel 3.2 vanilla with compat-wireless-2012-01-03 compiled on
top and I haven't gotten a kernel panic yet but I will post it if I
do.
I've also noticed that the less people in the office using WIFI, the
more stable the connection is (there are ~25 people in the whole
office using WIFI,  10 of them in the same room as me).
Wicd reports between 80-100% signal strength and the encryption is
WPA2 PSK. The AP is a PepWave AP One (3.1.0) and it is behind a wall,
in a room 15ft away from my desk.

Re: poor performance with BCM4331 and 3.2

George,
Also running a MacBook Pro (8,3) and seeing similar issues. I'll be connected to the AP, but I'll lose all internet connectivity every so often. Disconnecting and reconnecting to the AP works, or unloading and reloading the module. I'd like to help contribute to this to help it get fixed.

I'm even willing to donate root SSH access to the developers, if that helps. 

Thanks,
 - TK

A-phy

Larry, Rafal,

maybe this is not a new question on the list but I'm a little bit confused about a-phy support. I read on the
http://bcm-v4.sipsolutions.net/802.11/Multiband page that a-phy should be supported on 14e4:4319
which is pointed out as being a BCM4318, and 14e4:4312 that is BCM4311 instead. On
http://linuxwireless.org/en/users/Drivers/b43 I also read that "The 802.11a part of the 4311 is not
supported" and, in fact, I have a couple of devices which lspci displays as

03:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 01)
03:00.0 0280: 14e4:4312 (rev 01)

and dmesg says:
[  428.174190] b43-phy1: Broadcom 4311 WLAN found (core revision 10)
[  428.216031] b43-phy1 debug: Found PHY: Analog 4, Type 2, Revision 8
[  428.216055] b43-phy1 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2

And, in fact, a-phy is not activated (it actually seems completely disabled from initialization code).

So, is there any device I can buy for which b43 supports a-phy If the answer is yes (I really hope so :-) ) do you
have some pointers on ebay?

Many many thanks!
-Francesco

No, I do not think that there are any devices that support operation in the 5 
GHz band for b43. At the time when I was working on b43 (before I started 
reverse engineering), I did not have access to a 5G router. By the time I got 
the router, I had sent that BCM4312 802.11a/b/g device to you.

I have never revisited the A PHY specs. I have, however, been including any 5G 
band information for any new routines for which I create new specs. Rafał can 
speak to the extent that he has implemented this part of the specs.

Larry

Hm, the default action for posts my non-members was set to 'discard'.
That's just evil. I've fixed it to 'Accept'.

Maybe you did that to avoid spamming… ?

I just got one from Rafał (kidding).
