Help building compat-wireless

Help building compat-wireless

[Gary Thomas]

I'm struggling a bit to build compat-wireless in a cross-build environment.
I normally don't build kernels in-tree, rather I use a build tree, e.g.
   % cd <linux-source>
   % mkdir /tmp/kernel_build
   % make O=/tmp/kernel_build <some_config>
   % make O=/tmp/kernel_build uImage

I can't see how to use this setup with the compat-wireless package.
I tried [all the combinations I could think of] something like this:
   % cd <compat-wireless>
   % make KLIB=<linux-source> KLIB_BUILD=/tmp/kernel_build
However, this seems to not work as all I get are errors like this:
   /local/compat-wireless-2012-02-28/config.mk:242: "WARNING: CONFIG_CFG80211_WEXT will be deactivated or not working because kernel was compiled with CONFIG_WIRELESS_EXT=n. Tools 
using wext interface like iwconfig will not work. To activate it build your kernel e.g. with CONFIG_LIBIPW=m."

Does this process work in my workflow?  What do I need to do to
get it going?

Thanks

I managed to get past this, using this
   % make KLIB=/tmp/kernel_build KLIB_BUILD=/tmp/kernel_build
but to get it to actually build anything, I had to append the
'modules' target, e.g.
   % make KLIB=/tmp/kernel_build KLIB_BUILD=/tmp/kernel_build modules

Next problems:
* How do I select sub-options?  I only want WL12xx support with SDIO, but
   that requires some sub-options to be set that don't appear to happen.
   I get the main wl12xx module, but not wl12xx_sdio or wl12xx_platform_data
* There are a number of files which don't build against my 2.6.37 kernel,
   but none of these are important to me (they are in the bluetooth driver
   which I don't need, but nonetheless it gets built)
* The make/install is terribly broken for cross-builds.

I hacked my way past these problems and finally got some modules which
I can try.  Sadly, they don't work at all:
   # modprobe wl12xx_sdio
   wl12xx: loaded
   # ifconfig wlan0 up
   wl1271_sdio mmc1:0001:2: sdio write failed (-110)
   wl1271_sdio mmc1:0001:2: sdio write failed (-110)
   ...

Note: This driver in my kernel tree gets much farther than this - it
will actually download firmware and talk to the device, so I'm pretty
perplexed by this failure.

Any help greatly appreciated

Sadly, this one was my fault - one of my build hacks got in the way :-(

Now, I'm getting this error:
   wl12xx: ERROR could not get firmware ti-connectivity/wl127x-fw-4-sr.bin: -2
But this file is not available at the Linux firmware tree (git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git)

Where can I find it?

Thanks.  Do you know if these will be moving to kernel.org anytime soon?
My build recipes expect that to be the official home for firmware.

Yes, I sent a pull request for this to be included in
linux-firmware.git, but Ben hasn't pulled it yet.  Hopefully soon. :)
