Backporting wl1271 driver to kernel-2.6.32 using compat-wireless

Backporting wl1271 driver to kernel-2.6.32 using compat-wireless

[Elvis Dowson]

Hi,
                  I have a quick question. 

I downloaded the http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.37/compat-wireless-2.6.37-rc6-3.tar.bz2

The information contained in this link mentions: http://linuxwireless.org/en/users/Download/stable/

"You need kernel headers to compile compat-wireless. Ensure /lib/modules/$(uname -r)/build/ exists and points to the location where the kernel headers are installed. If you do not have them, read your distribution's documentation on getting help."

I have Ubuntu 10.04 as host, but I'm using a cross compiler for the OMAP3530 ARM target, and the kernel directory exists in a separate folder. 

How do I tell the build system to use my cross compiled kernel libraries and headers, and not pick up the host /lib/modules kernel headers? 

i.e. how can I cross compile and build compat-wireless for the ARM target on the host machine? 

cd /path/to/compat-wireless-2.6.32-rc5
./scripts/driver-select <driver-name>
make
sudo make install


Best regards,

Elvis Dowson

 export CROSS_COMPILE=arm-none-linux-gnueabi-

    i.e. how can I cross compile and build compat-wireless for the ARM
target on the host machine?

    cd /path/to/compat-wireless-2.6.32-rc5

copy appropriate configuration file to   /path/to/compat-wireless-2.6.

    32-rc5/.config

May also need to add configuration

    ./scripts/driver-select <driver-name>
    make
    sudo make install

It may be works without `sudo '. If you want all modules also
make modules_install INSTALL_MOD_PATH=${NFSROOT}
where NFSROOT is your directory to prepare filesystem for target

Hi,
         I set the following values in my .bashrc file
#
# Environment setup for u-boot and linux kernel
#

export ARCH=arm
export CROSS_COMPILE=arm-angstrom-linux-gnueabi-
export CROSSCOMPILER=armv7a
export CROSSTOOLCHAIN=${OVEROTOP}/tmp/sysroots/x86_64-linux/usr/${CROSSCOMPILER}

export UIMAGE_DIR="${KERNEL_DIR}/arch/arm/boot"
export KLIB="${KERNEL_DIR}"
export KLIB_BUILD="${KERNEL_DIR}"

I selected the wl12xx driver

$ cd /tool/patches/compat-wireless-2.6.37-rc6-3-patchwork
$ ./scripts/driver-select wl12xx

then I try to build it, but it gives me the following error:

I notice you have an android kernel, is that kernel a vanilla kernel
or did it get netdev_alloc_skb_ip_align() cherry picked into it?

netdev_alloc_skb_ip_align is not defined in the 2.6.32.27 vanilla
kernel. Someone else (google or ti) must have backported it to this
kernel and added it to your kernel.

I do not want to add some special handling into compat-wireless just for
some android kernel. Just remove netdev_alloc_skb_ip_align() and
NETDEV_POST_INIT from include/linux/compat-2.6.33.h and the compile
problems you posted should be fixed.

Well we did something to accommodate RHEL, I wouldn't mind supporting
some fudge for Android so long as someone is willing to submit the
patch and identify the kernel properly. Android is popular enough and
I rather reduce the time it takes to use it there than to create an
extra hurdle.

Now that I think about it I don't think John ever respinned his
patches for compat-wireless for RHEL.

No, I didn't.  Johannes wanted some sort of API level indicator instead
of checking for RHEL kernels, but I have no idea how to implement that.

FWIW, I'd rather you just take the patches I submitted and any
similar patches for other Enterprise-y distros (including Android).
But if someone else can demonstrate a workable, better alternative
then I will try to comply.

Yes, it is an android enabled 2.6.32 kernel. It also includes the TI 
OMAP35xx/AM35xx platform support package SDK v03.00.01.06/

I'd rather you figure out a way to identify that android kernel
somehow reliably and send a patch upstream to ifdef out
netdev_alloc_skb_ip_align() for that kernel, that way other Android
hackers can benefit.

This is from:

void ieee80211_led_init(struct ieee80211_local *local)
{
        local->rx_led = kzalloc(sizeof(struct led_trigger), GFP_KERNEL);
       ...
}

Looks good to me..  Not sure what can cause this, hrm.

In your kernel config CONFIG_LEDS_TRIGGERS is probably unset and then
net/mac80211/led.c should not be build at all. In the kernel
CONFIG_MAC80211_LEDS will select CONFIG_LEDS_TRIGGERS, but in
compat-wireless this should just be disabled.
I provided a patch for this problem, please apply it and try again.

Thanks for sending the patch across so quickly. I applied it and it built correctly.

However, I don't see a wl1271.ko module in the list of built files. The TI android
rowboard 2.6.32 kernel doesn't have an option for wl12xx or wl1271 at the moment
so, what do I do next? :-) 

Sorry, its my first time trying to use compat-wireless.

I only see the following kernel modules :

cfg80211.ko
compat.ko
compat_firmware_class.ko
mac80211.ko

Shouldn't a wl1271.ko or wl12xx,ko module be there? 

I configured compat-wireless for the wl12xx driver.

Hi Elvis,

Looks like you did everything correct. ;-)

Is CONFIG_CRC7=y set in your kernel config, the wl12xx module needs
this? If it is not set the module will not be build.

It wasn't :-). After enabling it in the kernel and recompiling both the kernel and 
compat-wireless wl12xx, it generated the following modules:

cfg80211.ko
compat.ko
compat_firmware_class.ko
mac80211.ko
wl1251.ko
wl1251_sdio.ko
wl1251_spi.ko
wl1271.ko
wl1271_spi.ko

I haven't applied the SDIO runtime PM patches yet. 

http://www.spinics.net/lists/linux-mmc/msg03966.html

So, is a wl1271_sdio.ko also supposed to be generated, but didn't because I didn't add the SDIO pm patches?

To use this at run-time on the target, should I do insmod for multiple modules:

insmod cfg80211.ko
insmod compat.ko
insmod compat_firmware_class.ko
insmod mac80211.ko
insmod wl1271.ko

Compat-wireless does not check what patches you applied to your kernel
yet, it just checks what kernel version you are using and want patches
are applied to it in the vanilla version. If you add some patches
yourself to the kernel to backport some stuff you have to manually edit
compat-wireless's config.mk file.

You also have to backport the CONFIG_WL12XX_PLATFORM_DATA and activate
it in your kernel config, wl1271_sdio depends on that.

Probably you have to change some other stuff on your architecture code
so that your device finds this sdio card, but I do not know what you
have to do exactly.

I was just thinking, run-time PM never made it to 2.6.32 right ? So, I might
not need to add those run-time PM patches ?

Ok, you mean back port that structure from 2.6.37-rc6 to the android-2.6.32 kernel?

I've already got the required kernel modifications for the kernel board-omap3beagle.c
file, and have already tested it out with vanilla linux-2.6.37-rc6 with the wl1271 driver, 
and it works.

So, I'll just need to port those changes across to the android-2.6.32 kernel and see if it
all works together.

It did.

You must, otherwise there is no way to power SDIO cards up and down..

Re: Backporting wl1271 driver to kernel-2.6.32 using compat-wireless

[Elvis Dowson]

Hi Ohad,
                   For 2.6.32, some more SDIO stuff needs to be backported. For example, I get the following error:

[   16.232482] mmc1: card claims to support voltages below the defined range. These will be ignored.
[   16.241424] mmc1: host doesn't support card's voltages
[   16.246643] mmc1: error -22 whilst initialising SDIO card


So, the part for handling reporting card voltages need to be added in.

Also the SDIO run-time PM patches are not nearly as easy to apply to the android-rowboat-eclair-2.6.32 kernel.

Is the SDIO subsystem sufficiently modular so as to allow me to take a few file and use it as a drop in 
replacement for the 2.6.32 kernel?

I'm not sure I'm following the question...

btw, IMHO you don't need to replace any file at all. 2.6.32 has a
functional SDIO subsystem.

Has anyone on the list backported CONFIG_WL12XX_PLATFORM_DATA to 
2.6.32, and got wl1271_sdio.ko to build?

I did as you suggested and was able to get wl1271_sdio.ko to build.

I have attached a patch for this, which can be applied on top of the TI android rowboat-eclair-2.6.32 kernel branch. This kernel works with android-2.2.1 (froyo), although the kernel was originally developed for android eclair.

Hi,
        The following patch has to be added to the one I sent out ealier for backporting wl12xx_platform_data.

Hi,
       I think the .startup_delay field is missing in the fixed regulator for 2.6.32. 

I recall from the datasheets that during a reset, the WL_EN line should asserted
low for atleast 64 to 70ms before turning the power back on.

What do you think I should do?


/* Fixed voltage regulator for wlan module */
static struct fixed_voltage_config beagle_vwlan = {
	.supply_name		= "vwl1271",
	.microvolts		= 1850000, /* 1.8V */
	.gpio			= OMAP_BEAGLEBOARD20_WIFI_PMENA_GPIO,
	.startup_delay		= 70000, /* 70msec */
	.enable_high		= 1,
	.enabled_at_boot	= 0,
	.init_data		= &beagle_vmmc2,
};

Hi,
       When working with the wl1271 backport to 2.6.32 kernel, is CONFIG_MMC_EMBEDDED_SDIO=y required?

Nope. wl1271 doesn't need it - the device is dynamically probed,
identified and configured.
