Right now we are copying code for building kernel 2.6 modules to each
spec which provides them. It is a little hard to maintain and to add
some functionality. I have created macro for building modules based on
that code, a little expanded (with cross-compilation support). Now in
spec file thete will only have to be some thing like:
%if %{with kernel}
cd module/place
%build_kernel_modules module_name1 module_name2
cd ../..
%endif
If some additional options for make modules are required they may be
passed like: -1 option1 -2 option2 -3 option3; up to 9 options are
supported.
Exemple when some additional option in make modules is required:
%build_kernel_modules -1 T=$TMPDIR mol
There may be 2 options passed to make prepare scripts: -p o1 -P o2.
Module patching is supported via shell script called pld-module.patch.
Exemple with additional patching:
%if %{with kernel}
cp -f pwc-if.c pwc-if.c.orig
cat > pld-module.patch <<'EOF'
set -e -x
if grep -q "CONFIG_PREEMPT_RT" o/.config; then
sed 's/SPIN_LOCK_UNLOCKED/SPIN_LOCK_UNLOCKED(pdev->ptrlock)/' \
pwc-if.c.orig > pwc-if.c
else
cat pwc-if.c.orig > pwc-if.c
fi
EOF
%build_kernel_modules pwc
%endif
Now, take a look at the code and propose your additions! Number and use
of backshashes is scary, but it has to be this way as %define is expanded
before anything.
