If this is a recent compat-wireless, then the wl1251 driver was moved to
drivers/net/wireless/ti/wl1251. Can you check that?
I initially used compat-wireless-3.3.1-1 as it was the latest "stable"
kernel edition released. The wl1251 drivers are in
net/wireless/wl1251, not drivers/net/wireless/ti/wl1251. That is also
the case with the latest released compat-wireless - 3.4-rc3-1.
I did a bit of hacking/tweaking, but ran into much bigger problems and
simply gave up in the end. When I looked at various compat-wireless
makefiles I saw that, somehow the inclusion of wl1251 as well as
wl12xx depends on CONFIG_CRC7 and CONFIG_WL12XX_PLATFORM_DATA being
set (the latter also depends on wl12xx, so if I wanted it included, I
had to switch to "wl12xx" instead of "wl1251"). So, I did the following:
./scripts/driver-select restore
./scripts/driver-select wl12xx
make ARCH=arm CROSS_COMPILE=$CCOMPILER KLIB=<android_kernel_dir>
KLIB_BUILD=<android_kernel_dir> CONFIG_CRC7=y
CONFIG_WL12XX_PLATFORM_DATA=y
I then get the following errors:

Apparently, "pm_runtime_enabled" is defined in
include/linux/pm_runtime.h, but this is for the 3.0+ version of the
kernel - I am using 2.6.37! Something seems to be seriously screwed
up! The above is valid for all 3.x versions of compat-wireless I
tried! I was under the impression that compat-wireless is
backward-compatible with "older" kernel versions, like mine, is that
not the case?!
When I tried the latest compat-wireless before 3.x (2.6.39-1) I don't
get the first error, but get the other two, albeit with modified
function names (wl1271_sdio_* instead of wl12xx_sdio_*).
In addition to the above, for some reason when I run compat-wireless
for versions prior to 3.x (I tried 2 such versions - 2.6.39-1 and
2.6.38-2) I also get a weird error that
"<android_kernel_dir>//builddir/compat-wireless-XXX/net/wireless/db.txt
cannot be found" - the search path there is completely wrong, it
should either be <android_kernel_dir>" or
"/builddir/compat-wireless-XXX/net/wireless/db.txt" and not this weird
concatenated path containing both!
Again, this only happens with the 2 releases prior to 3.x I tried and
only when I have "db.txt" and "genregdb.awk" from 3.3.1-1 manually
copied to net/wireless. Any help?
I've had somewhat limited success with this - I was able to build
2.6.38-2 compat-wireless by manually copying "db.txt" as well as
"genregdb.awk" to
<android_kernel_dir>//builddir/compat-wireless-XXX/net/wireless (yeah, I
created it manually) as well as forcing CONFIG_CRC7=y and
CONFIG_WL12XX_PLATFORM_DATA=y.
"make modules-install" gives me 6 modules: compat, cfg80211, mac80211,
wl1251, wl12xx_platform_data and wl1251_sdio. I "modprobe" them in that
order, but then I get this error:

evident from the above also, the firmware does not load either. Here is

I have also tried to build the latest snapshot (tried the one from 21
April 2012), but things there got a bit more messy - the ti drivers were
indeed moved to the ti/ directory, the Makefile, however, after
selecting "ti" (or any of the TI drivers - TI1251 or TI12XX) is
completely empty. I did a bit of investigation and it turns out that the
offending part of the code is in the select-driver script, which
executes "egrep WL1251|WL12XX" on the original Makefile and since the
Makefile CONFIG_* setting does not contain either of these values for
the ti/ directory (it has something like CONFIG_TI_*) that results in an
empty Makefile.
Even if I correct this and leave just the ti-related settings in that
Makefile, I am still faced with my original problem I already pointed
out above - wl1251, wl1251_sdio and wl12xx are not built - just compat,
mac80211 and cfg80211 are compiled, so I am stuck - good and proper, again.
Luciano, anyone?
