wanted: PCI driver for 3.2 kernel
 

My machine has a mini PCIe card on which are 2 off RS485 ports. Here is the o/p from uname -a

Linux fujitsu-debian-shcp1 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3 x86_64 GNU/Linux

Here is the o/p from lspci

I don't think the mini-PCIe card has been recognised. I've contacted the supplier of the machine, and he suggested downloading a PCI driver from fujitsu, which I did. However I can't build it, the make falls over with:
"linux/smp_lock.h: No such file or directory"

Given that I have a 3.2 kernel, and that the name of the directory supplied from fujitsu is:
"mPCI3-AddonLinux2.6"
I conclude that this 'ere driver needs an update to make it work with a 3.2 kernel. I've asked the machine suppliers, who can't help, I've done lots of googling and drawn a blank.

I can't be the only person who want a driver like this to work with a 3.2 kernel!

Does anyone know where to look?

Do you have the Linux headers installed?

The big kernel lock was removed in 2.6.39.
I don't think any driver will work if the device doesn't show up on the PCI bus. How would the driver find it? lspci should still list it as "Unknown device".

Quite right. I'll have to solve that one before doing angthing else
