Develop wifi driver for kernel 3.0

[sijothakadiyel]

Sir

I am presently using 2.6.x kernel with fedora operating system . I wish to switch to kernel 3..x.x kernel. One problem that i am facing is that my wifi driver is not compactable with 3.x kernel . I wish to take it as my final year PG project . So please help me to approach this in a systematic way . [ i have the source code of wifi driver for 2.6.X kernel ]. My question is how to recode the source code for 3.x.x kernel . . I have some kind of system programming experience .

Help me please

I think you likely are wrong about that driver not working with current Linux kernels. Have you read something about it not working with current kernels? I would expect you to be able to compile that from source as is and use it. But most people here install the binary kmod version available from the RPM Fusion repo. It is available there for current 3.x Fedora 16 and Fedora 17 kernels. There also is an akmod version of it there.

P.S.: You haven't mentioned your adapter's wireless chipset. There are multiple drivers for Broadcom chipsets, and there is overlapping support for some of them. You may be able to use a driver that is supplied by the current Linux kernel.

sir
my wireless card is dell wl-minicard dell1397 ( bcm4312) . I download the source code from the site [www.broadcom.com/support/802.11/linux_sta.php ] and tried to compile it . But end up with errors. ... .

Any other option to enable the wl card in new version of fedora operating system like 16 and possibly 17 ....

with regards

Try the attached patch

That patch appears to do exactly what these folks here were doing last week here...

Well, it worked for them, so it's probably what you need. Apply the patch to the source and find out.

The changelogs for the latest kmod-wl mention applying a patch for the new kernels...

2012-06-08 - Nicolas Vieville <nicolas.vieville@univ-valenciennes.fr> - 5.100.82.112-3 - Added patch to build for kernel >= 3.4

I hadn't heard about any of this til now. Sorry.

When I googled the error message "/wl_linux.c:388:2: error: unknown field" I got this as the top hit

The fedoraforum post didn't feature as I had already fixed the asm header

If I had realized it was just the wl driver I would have pointed him to the rpmfusion package.

yum install akmod-wl
