This time I don't understand what is going on with the error:
/root/modules/backports-3.14-1/net/mac80211/key.c:813: error: implicit
declaration of function 'atomic64_set'
If I search for this function definition I see it is in compat_atomic.c
file:
wsos-sdk:~/modules/backports-3.14-1# grep -r --include="*.c" atomic64_set .
./net/mac80211/key.c: atomic64_set(&key->u.ccmp.tx_pn, pn64);
./net/mac80211/key.c: atomic64_set(&key->u.aes_cmac.tx_pn, pn64);
./compat/compat_atomic.c:void atomic64_set(atomic64_t *v, long long i)
./compat/compat_atomic.c:EXPORT_SYMBOL_GPL(atomic64_set);
Now I search for it in the compat Makefile:
wsos-sdk:~/modules/backports-3.14-1# grep compat_atomic.o compat/Makefile
compat-$(CPTCFG_BACKPORT_BUILD_GENERIC_ATOMIC64) += compat_atomic.o
And I see in .config that I do have that config option enabled:
wsos-sdk:~/modules/backports-3.14-1# grep
BACKPORT_BUILD_GENERIC_ATOMIC64 .config
CPTCFG_BACKPORT_BUILD_GENERIC_ATOMIC64=y
and it works because I see tha the compat_atomic.o is generated during
the compilation so, I guess that the problem is exporting the symbol
with EXPORT_SYMBOL_GPL(atomic64_set)
any clue about how to solve this?
Seems to me you need the function prototype in some backports header
file. Try the patch below. Probably not the right way to do it. By the
way, it would help if you would mention the target kernel for which you
want to make the build.

Hi,
after a bit more investigation I found this:
wsos-sdk:~/modules/backports-3.14-1# grep compat_firmware_class
compat/Makefile
obj-$(CPTCFG_BACKPORT_BUILD_FW_LOADER) += compat_firmware_class.o
so I looked in compat/Kconfig and found this (I didn't find it before
because I grep with the CPTCFG_ header):
config BACKPORT_BUILD_FW_LOADER
tristate
depends on m
# RHEL6, starting from 6.0, backports the FW loader already
depends on !BACKPORT_RHEL_KERNEL_6_0
depends on !FW_LOADER || BACKPORT_KERNEL_2_6_33
default m if BACKPORT_FW_LOADER
default m if BACKPORT_USERSEL_BUILD_ALL
config BACKPORT_FW_LOADER
bool
from here I understand that I have to enable de BACKPORT_FW_LOADER
option.
I haven't found it in menuconfig so I changed it manually in
compat/Kconfig to 'def_bool y'
Now the error went away but a new one appeared:

Hi,
when I try to compile backports-3.14-1 in a 2.6.30 kernel I get this

I saw that in backport-include/linux/firmware.h there is a
pre-compiler directive to use the backport's version of
request_firmware_nowait function:
#if defined(CPTCFG_BACKPORT_BUILD_FW_LOADER_MODULE)
#define request_firmware_nowait LINUX_BACKPORT(request_firmware_nowait)
But I haven't found where the CPTCFG_BACKPORT_BUILD_FW_LOADER_MODULE
is defined.
I just ran:
make defconfig-ath9k
make
Am I missing a previous configuration step?
Thanks!
