I'm trying to do the following: 1) add the smi2021 driver for EasyCap Somagic usb frame grabbers into the kernel tree 2) compile the kernel with smi2021 as a module 3) build the rpm. I got the driver from Jon Arne Jorgensen's kernel branch on github: https://github.com/jonjonarnearne/smi2021 then tried to follow these instructions: https://fedoraproject.org/wiki/Building_a_custom_kernel but the whole thing fails with this eror: Patch100000: smi2021.patch + case "$patch" in + patch -p1 -F1 -s + chmod +x scripts/checkpatch.pl + touch .scmversion + mkdir configs + for i in '*.config' + mv kernel-3.17.8-aarch64.config .config ++ head -1 .config ++ cut -b 3- + Arch=arm64 + make ARCH=arm64 listnewconfig + grep -E '^CONFIG_' + '[' -s .newoptions ']' + cat .newoptions CONFIG_VIDEO_SMI2021 + exit 1 error: Bad exit status from /var/tmp/rpm-tmp.sASN4F (%prep) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.sASN4F (%prep) So I spent a lot of time trying to figure this out and I know why it happens but I don't know how to fix it. The smi2021.patch being applied above is the diff between the kernel trees with and without the driver. The patch succeeds. The problem is that in order to have the module compiled I did make oldconfig and so I ended up with CONFIG_VIDEO_SMI2021=m in the kernel-3.17.8-x86_64 **ONLY**. Then the kernel.spec has some code that runs oldconfig over **ALL** the kernel*.config files: for i in *.config do mv $i .config Arch=`head -1 .config | cut -b 3-` make ARCH=$Arch listnewconfig | grep -E '^CONFIG_' >.newoptions || true %if %{listnewconfig_fail} if [ -s .newoptions ]; then cat .newoptions exit 1 fi %endif rm -f .newoptions make ARCH=$Arch oldnoconfig echo "# $Arch" > configs/$i cat .config >> configs/$i done # end of kernel config %endif Of course, none of the other config files (for other architectures then x86_64) have the CONFIG_VIDEO_SMI2021 options, hence the error. So the key question is what is the proper way to add a new driver to the kernel tree and run rpmbuild -bb --target=$(uname -m) kernel.spec on it? Do I put CONFIG=VIDEO_SMI2021=m in SOURCES/config-local, or what? For what it's worth, I am able to do make oldconfig # picks up the option for the new driver make in the kernel tree with the new code in it and it goes through without errors. So if I want to run the new kernel with the new driver, I can, but I'd rather do this by building the custom rpm, as I don't know when or if this driver will be included in the vanilla kernel. Please help, I'm at the end of my wits.
