Is it possible to add patch specific to a kernel modules?
For example i build ath10k from the kernel source but i want to add patches to the code. How to do this?
An alternative would be to create a metapackage that use the kernel source as build dir and compile .ko module on his own. Any idea?
Have a look at this: https://wiki.openwrt.org/doc/devel/patches
About half way down is the section specifically for kernel patches.
patches for wifi are located at package/kernel/mac80211/patches
and the resulting files are (here is an ar71xx target):
build_dir/target-mips_24kc_musl/linux-ar71xx_generic/backports-2017-11-01
I mean for the modules build from the kernel source
That dir is based on backport zip
in the target folder you usually have a folder patches-4.14, if you work for 4.14
or if you want for all targets, use de generic folder
Hello, I'm trying to create a patch for tplinkCPE210_v3. I use Openwrt SNAPSHOT, r7821-bfff412536
I have read https://wiki.openwrt.org/doc/devel/patches
I do the following steps:
cd /TestPatchTplinkCPE210V3/tplinkcpe210v3/openwrt/
make clean
make -j8 V=s
All ok
make target/linux/{clean,prepare} QUILT=1 V=s
cd build_dir/target-mips_24kc_musl/linux-ar71xx_generic/linux-4.9.119/
quilt new generic/999-fix_jump.patch
Patch patches/generic/999-fix_jump.patch is now on top
7. quilt edit drivers/net/wireless/ath/ath9k/init.c
8. quilt diff

At the time of assembly, there were no errors. The firmware file was assembled, but as I understand the patch was not overlaid.
I searched all the init.c files and looked at the changes in them. In total there were 3 of them.
Modified file number 2 in the picture. It has a path:
/home/openwrt/TestPatchTplinkCPE210V3/tplinkcpe210v3/openwrt/build_dir/target-mips_24kc_musl/linux-ar71xx_generic/linux-4.9.119/drivers/net/wireless/ath/ath9k>
In other directories, the file remains the same. So it should be?
As I understood that the patch did not overlap:
build_dir/target-mips_24kc_musl/linux-ar71xx_generic/backports-2017-11-01 What am I doing wrong?
no "quilt refresh"?
Thanks for your reply.Correctly, I think that this should be done after step number 8? After quilt diff ?
I also tried the 'quilt refresh' after step № 8, the result is the same. maybe an https://wiki.openwrt.org/doc/devel/patches instruction
with mistakes ?
