Wireless BCM4312 with the 3.10, 3.11, 3.12 and 3.13 kernels

Broadcom Chipset BCM4312
The hybrid driver from Broadcom was updated again in September (2013) with all the previous patches and a few other fixes as well. This brings them up to support linux kernel 3.9, which is very much welcome.

Sadly it breaks again with >= 3.10 with many warnings and errors which isn’t good considering that Ubuntu (13.10) Saucy Salamander is about to be released.

We do have a patch for you though that gets us working again up to the 3.11 kernel.

Chipsets supported by “Broadcom’s IEEE 802.11a/b/g/n hybrid Linux® device driver” are: BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227 and BCM43228.

Wireless BCM4312 with the 3.6, 3.7 and 3.8 kernel

Broadcom Chipset BCM4312 As a follow up to , I’ve also tested the Broadcom hybrid driver with the 3.6, 3.7 and the soon to be released 3.8 kernels with success. There have been no major changes that should effect the operation of this driver.

To verify that everything is working as expected on the software side, when modprobe or insmod wl, you should get a similar dmesg output:

[ 307.560347] lib80211: common routines for IEEE802.11 drivers
[ 307.560353] lib80211_crypt: registered algorithm ‘NULL’
[ 307.564524] wl: module license ‘unspecified’ taints kernel.
[ 307.564529] Disabling lock debugging due to kernel taint

Wireless BCM4312 with the 3.4 and 3.5 kernel

Broadcom Chipset BCM4312
The hybrid driver from Broadcom is still a bit behind in terms of support for the latest kernels but there are workarounds. This particular issue also effects other kernel modules such as the out of tree Nvidia and ATI blobs that require the asm/system.h file in their includes.

I’ve had success with replacing it with asm/switch_to.h which seems to have fixed things for now. The cause for this can be found on the LKML.

Chipsets supported by “Broadcom’s IEEE 802.11a/b/g/n hybrid Linux® device driver” are: BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, and BCM43225, BCM43227 and BCM43228.

Wireless BCM4312 3.2 kernel

Broadcom Chipset BCM4312

Since there is an Ubuntu package ‘firmware-b43-lpphy-installer’ which is up to date and will work against the 3.0 kernel, my earlier posts are obsolete. If you are not running Ubuntu, then you will still need to reference my post.

The latest 3.2 Linux kernel however has a few ABI changes, most notably in the network stack which effects the Broadcom’s wl module. Most notably is: .ndo_set_multicast_list which was replaced with .ndo_set_rx_mode.

Wireless BCM4312 3.0 kernel

Broadcom Chipset BCM4312

With the latest 3.0 kernel there is still no “out of the box” support for my BCM4312 wireless chipset. Nor is there any help from Ubuntu 11.04 leaving me to use Broadcoms hybrid driver with patch.

Chipsets supported by “Broadcom’s IEEE 802.11a/b/g/n hybrid Linux® device driver” are: BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, and BCM43225, BCM43227 and BCM43228.

My specific chipset from lspci command:
