[wireless-next][PATCH 0/3][ANNOUNCE] b43 the first Linux driver supporting HT-PHY (BCM4331)!

[Rafał Miłecki]

After improving DMA (the important patch for BCM4331 is my one) we can finally
enable support for HT-PHY. The whole code has been written from MMIO dumps
grabbed from ndiswrapper+windows driver, but seems to be stable and was tested
by 3 people. Unfortunately there are still some missing conditions that can't
be fixed without RE the closed driver or having Broadcom co-operating. However
it seems we live with that well enough for basic usage :)

BCM4331 doesn't have any Linux driver yet, both: wl and brcm80211 don't support
it. So we can be really proud of it ;) Ah, and I should mention that ndiswrapper
was frequently reported to lock up machines when working with this card (see
Ubuntu's forum about MacBook 8.1).

To use b43 with BCM4331 you will need to grab the newest b43-fwcutter and
extract firmware from some recent closed source driver. See our wiki page in
few hours for nice howto.

Big thanks go to David Woodhouse for providing me access to his MacBook, letting
grab the dumps, test patches and debugging a lot of hard cases with me (and
sometime without ;) ).

Massive congratulations. I can confirm that the 4331 does indeed lock up
the MBP 8,1 with ndiswrapper so this is hugely appreciated.

Good job.

I'd really like to thank you guys for your great work on the driver.
You made some really significant improvements to the driver in the last few
months and thus ported b43 over to the latest and greatest broadcom
wireless devices. Things looked messy with only legacy G-PHY support,
but then you guys appeared. ;) Thanks.

The "guys" are really only one guy, Rafał. His ability to convert ugly mmio 
dumps into code is remarkable.

I've checked the wiki page and downloads area but the latest version of
fwcutter that I could find was from several days ago.

Can anyone direct me towards the latest b43-fwcutter download as
mentioned above?

Can't wait to get 4331 support!

Many thanks

Just use the howto for kernel 3.2 (I know it's a little tricky for now
to use 3.2, wireless-next is also OK for that howto):
http://wireless.kernel.org/en/users/Drivers/b43#Other_distributions_not_mentioned_above

You have to:
1) Clone git repository wireless-next
2) Apply 3 patches from this patchset
3) Compile kernel with B43_PHY_HT
4) Install firmware (I think you already started that part)

b43-fwcutter in 015 version is alright for extracting 666.2 firmware.

Thanks for your support on this.

I'm not too knowledgeable when it comes to kernel development. However,
I am eager to learn.

I've cloned the repo and have wireless-next.

Can you tell me where I will find these 3 patches to apply them to
wireless-next?

Many thanks

You can find them on b43-dev ML archive. You can copy them and paste
into 3 separated text files.

However to make it easier to you, I've also uploaded them to http server:
http://files.zajec.net/enable-ht/0001-b43-Relax-requirement-for-descriptors-to-be-in-the-D.patch
http://files.zajec.net/enable-ht/0002-b43-use-8K-buffers-for-64-bit-DMA-to-workaround-hard.patch
http://files.zajec.net/enable-ht/0003-b43-make-HT-PHY-support-experimental.patch

Save all that 3 files on your disk and then do:

cd /foo/bar/wireless-next
git am 0001-b43-Relax-requirement-for-descriptors-to-be-in-the-D.patch
git am 0002-b43-use-8K-buffers-for-64-bit-DMA-to-workaround-hard.patch
git am 0003-b43-make-HT-PHY-support-experimental.patch

After that use "make menuconfig", enable BCMA, enable support for BCMA
in b43 and enable HT support in b43.

Thanks for your help.

Will I find the ability to enable support for BCMA and HT support in the
menuconfig file or elsewhere?

Yes. menuconfig has great feature of searching. Just enter "/" key and
type phase you're looking for. For example type "/BCMA" and press
ENTER. What you want is:
Device Drivers -> Broadcom specific AMBA -> BCMA support
Device Drivers -> Broadcom specific AMBA -> Support for BCMA on PCI-host bus
Device Drivers -> Network device support -> Wireless LAN -> Broadcom
43xx wireless support -> Support for BCMA bus
Device Drivers -> Network device support -> Wireless LAN -> Broadcom
43xx wireless support -> Support for HT-PHY (high throughput) devices
