Compat-wireless N900

Compat-wireless N900

[George]

Hi all,

I'm trying to use compat-wireless to upgrade my n900 wireless driver. 
N900 is using WL1251 wireless driver and the omap1 kernel version used 
it 2.6.28.

The issue is that 2.6.28 does not have implemented many issues for 
nl80211 netlink family which I wanted to test on my n900.

I have recompiled the kernel to make cfg80211 and mac80211 modules, so I 
can use compat-wireless. After that I have compiled compat-wireless by 
selecting the driver family I need. All done under scratchbox.

# scripts/driver-select wl12xx
# make KLIB=/lib/modules/2.6.28-myversion \
    KMODPATH_ARG=/lib/modules/2.6.28-myversion
# make  KLIB=/lib/modules/2.6.28-myversion \
    KMODPATH_ARG=/lib/modules/2.6.28-myversion install

After that I have installed the new kernel and the drivers in the n900 
and the system starts. `uname -a` reports I'm using my custom kernel.

The problem is that the wireless modules are not working as expected and 
I cannot get access to my wifi networks. Actually bluetooth is not 
working as well, as far as I have tested.

dmesg reports --> http://pastebin.com/xskKcGnE

I have hightlighted the lines that seems to be reflecting what is not 
working. So it seems that on startup it is trying to upload the former 
wl12xx.ko module. Then I decided to manually upload the new modules to 
check them out.

$ sudo gainroot
# modprobe wl1251_spi
# ifconfig -a
---- no wlan0 iface ----
# iwconfig
---- no wireless devices ----

I have also tried with wl1251_sdio driver but I have the same problem. 
dmesg doesn't report any error while uploading these drivers, but I 
don't know why not a new wireless interface is not created.

BTW, the firmware is in /lib/modules/firmware so it is in a place that 
can be found. Do I have to change something?

What files do I need to reconfigure as to get the kernel to point to the 
correct driver upon booting?
How do I create a new wireless interface if the driver is uploaded 
properly but the interface is not created?
Any other issue that you find I'm not doing correctly?

Any help is welcome.

Regards,
George

At first sight it seem that you have some mismatch issues,
Try to compile the maemo 2.6.28 kenrel without the wireless modules or
replace the wireless modules by the compat-wireless ones.
(normally the compat-wireless modules should take the precedence but as
it seem here, it didn't work)

by the way, are you aware of the meego 2.6.35 kernel, it might not be
complete yet, but may solve some of your problems.

Agreed, try:

for i in mac80211 cfg80211 wl1251_spi; do modprobe -l $i; done

This will show you where its picking up the modules upon load. If you
see some disagreement with paths, that's the issue. Compat-wireless
relies on stuffing them on your /lib/modules/$(uname -r)/updates/
directory and in order for these modules to take precedence over the
/lib/modules/$(uname -r)/kernel/ modules we rely on a file in
/etc/depmod.d/ which tells depmod to prefer updates first. For example
on an ubuntu box you get:

mcgrof@tux ~ $ cat /etc/depmod.d/ubuntu.conf
search updates ubuntu built-in

What I want is to get iw and nl80211 working properly so I can use 
netlink sockets to get all the information. Currently I cannot do 
anything as every iw command reports operation not supported.

If I compile the kernel withouth the wireless modules then they are not 
going to be recognized and compat-wireless will complain that .config 
that kernel was compiled without wireless.

On the other hand, what do you mean by replacing the wireless modules? 
just cut and paste from compat-wireless.

The issue is that 2.6.28 has nl80211, cfg80211 and mac80211 on their 
very stages. I think what will solve my problem is just updating those 
modules, but for that I have to change also the driver.

Besides that, the main problemm, as some guys pointed in the IRC 
channel, is that wl1251 driver is spi and they need something about the 
board interfaces.

Yes I'm aware of that. I have compiled the kernel and try to load it on 
the n900 with maemo rootfs and ... crashes.

Actually I have meego (mmc rootfs) also running on my N900 and wireless 
drivers work perfect. The problem is that the gui and develepment SDK 
and toolchains are still underdevelopment and I cannot then use 
something like the maemo scratchbox.

I have compiled an small application directly on the n900 with meego, 
but for larger applications it is not viable.

Are you sure you have the right module?

I have tried using even insmod and the modules load perfectly but the 
wlan device doesn't show up.
In dmesg nothing is displayed except for the cfg80211 and when I rmmod 
the module wl1251 (wl1251: removed or similar)

I'm still wondering what the hell I have to do.

Yes. The driver is the wl1251 family. As I said in previous posts and 
from what some guys in the IRC channel tried to guess, it seems that the 
problem might be in that the spi interface is specific for any device, 
and in the n900 might be different from the one implemented in 
compat-wireless.

I'm a bit suprised about this fact, but they know more than I.

Heh, nope.

> I'm a bit suprised about this fact, but they know more than I.

Or, we had not yet accommodated yet for the fact that the wl1251
driver was split out into its own directory from the original wl12xx/
directory and no one ever sent a patch to fix this on compat-wireless.
I just fixed this on today's compat-wireless, so you can try that
around noon PST time when the new tarball will be generated. Ah but
there are some pcmcia crap compile issues, we just have to remove
pcmcia support, well not now, I have other stuff to do.

I welcome patches if someone gets to it.

Thanks for that. Tomorrow at work I will try to test it out and get back 
to you if something happens ;)

I'm sorry but my knowdledge of the system is from a higher level of 
abstraction. Otherwise I will be soooo please of helping you out.

I have downloaded compat-wireless-2010-10-17.tar.bz2 and have compiled 
the code with no problem. I have seen the changes you've made creating 
modules wl1251, spi and sdio.

I have run modprobe spi to upload the modules (also tried sdio) and no 
way. dmesg doesn't include any message. Below is the one after unloading 
the modules and uploading them again:
rmmod spi wl1251 mac80211 cfg80211 compat_firmware_class
modprobe spi

 >>
wl1251: unloaded
cfg80211: Calling CRDA to update world regulatory domain

Below is the output for lsmod. As you can see modules are up and 
running, but when I execute ifconfig -a no wlan0 device shows up.

Nokia-N900:~# lsmod | grep spi

Any help on that? Sorry but I'm somehow desesperate and don't know what 
to do. Actually I'm thinking on not using compat-wireless and nl80211 
and get back to wireless-extensions.

Does your device use SDIO or SPI?

Getting back to wireless-extensions would certainly be a very desperate
measure! :P

On the N900 the wl1271 chip is connected via SPI.

I'll re-read this thread more carefully to see if I can spot anything
that could help you.

First thing that came to my mind after re-reading the thread... Does the
wl1251 driver work *without* compat-wireless? Where did you get the
kernel that you have compiled?

My initial guess is that the SPI is not configured correctly so the
probe function is never called in the wl1251_spi module and thus the
interface is never created...

The chip is a wl1251, isn't it? wl1271 is n capable and n900 is not.

I don't now how to test the driver without compat-wireless. If you can 
explain it I will try. Do I have just to copy driver code on 
compat-wireless directly into my kernel source directory? I don't think 
that would work and probably complain, but I can try if this is the way.

> Where did you get the
> kernel that you have compiled?

The kernel is the official one for n900, kernel-2.6.28 (uname -a returns 
2.6.28-omap1). I got it using scratchbox and downloading it with:

sb# apt-get source kernel

Then I have compiled it using:

sb# make EXTRAVERSION=-mine rx51_defconfig
sb# make EXTRAVERSION=-mine menuconfig
sb# make EXTRAVERSION=-mine bzImage modules
sb# make EXTRAVERSION=-mine modules_install

After that I have compiled on scratchbox compat-wireless package:

sb# cd compat-wireless-2010-10-17
sb# scripts/driver-select wl12xx
sb# make KLIB=/lib/modules/2.6.28-mine 
KMODPATH_ARG=/lib/modules/2.6.28-mine
sb# make KLIB=/lib/modules/2.6.28-mine 
KMODPATH_ARG=/lib/modules/2.6.28-mine install

Then move the new set of modules to my n900

n900# mkdir -p /lib/modules/2.6.28-mine

# cd /lib/modules/2.6.28-mine
# scp -r updates/ kernel/ modules.* 
root@192.168.2.15:/lib/modules/2.6.28-mine

And then boot with the new kernel image

ubuntu$ sudo flasher-3.5 -l -b -k 
PATH_TO_KERNEL/kernel-2.6.28/arch/arm/boot/zImage

I'm attaching a link to my .config file to check if you consider I have 
to activate any other stuff.

I think your problem is that the driver (in
drivers/net/wireless/wl1251/spi.c) and spi_board_info (in
arch/arm/mach-omap2/board-rx51-peripherals.c) names don't match
(wl1251 vs wl12xx). Probably easiest to edit .modalias in
board-rx51-peripherals.c and rebuild the kernel.

You should just use "wl1251", not spi:wl1251, so it becomes:

{
                .modalias               = "wl1251",
                .bus_num                = 4,
                .chip_select            = 0,
                .max_speed_hz           = 48000000,

It seems getting closer ;)

After changing wl12xx for spi:wl1251 now modules are uploaded on startup.

However this is the output from lsmod | grep spi
spi                     4352  0
wl1251                 75840  1 spi
mac80211              256892  2 spi,wl1251
crc7                    1216  1 spi

As you can see spi module is not used :( and no interface is created. 
Still a way to go.

You need both wl1251 and spi. This is normal output, you should get
wlan0 interface at this point.

Tried and got a similar behaviour as when using spi:wl1251.

I have also set the debug ALL mode to see if I get something that can 
help you out on finding the problem.

When uploading only wl1251 nothing appears in dmesg. But when uploading 
module spi, I got the following info: http://pastebin.com/ysdTSDnB

Yes, that is what I was expecting from the begining but although phy0 
should appear in /sys/class/ieee80211, this directory is empty :(

It seems that it tries to do something but it is not finally done. 
However, as you can see it seems there is no error (at least reported). 
Could it be that spi_read buf is almost everytime reading 00 00 00 00?

Another issue is that I have to manually upload the spi module as by 
default it only uploads wl1251 but not the spi. But this is not a big deal.

Again, thank you all for the help... You are almost there (I cannot say 
we as I've been only following your advices).

Hm, maybe try enabling CONFIG_MAC80211_DEBUG* stuff in config.mk in
compat_wireless.

I have done that and no extra messages appear besides the former ones :(

Any other idea :(

I have look at compat-2.6.28.c and in the comments it says that is for 
kernel 2.6.28. However it is not compiled as in the #ifdef it is said to 
be < 2.6.28. Is it right? I guess yes, but just for curiosity.

No other idea :(

If you get nothing but zeros back from the device, most likely that
means that it's not powered up properly. 

wl1251 chip on n900 is powered up by using a gpio line. I'm worried
that the struct wl12xx_platform_data wl1251 wireless-compat driver
expects (defined in /include/linux/wl12xx.h) doesn't match what the
old maemo kernel provides. Unfortunately I can't remember anymore what
the platform data was like in maemo kernels and there's no easy way
for me to check that right now.

Thanks a lot for that hint. Now I'm involved in another issue but when I 
have more time I will look at those .h, but don't expect too much from 
me as I'm not expert but just user.

Thanks a lot.
