Compiling and Building the Package
NOTE: Clean up before rebuilding
Example for x86_64:
$ make x86_64_defconfig $ make deb-pkg LOCALVERSION=-foo KDEB_PKGVERSION=$(make kernelversion)-1
Example for armhf (cross compilation):
$ make multi_v7_defconfig $ make deb-pkg ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LOCALVERSION=-foo KDEB_PKGVERSION=$(make kernelversion)-1
If you want to build the package without clean the kernel you can use bindeb-pkg instead.
$ make bindeb-pkg ...
Speeding up cross-compiling with ccache
Install the c compiler cache, i.e
$ apt-get install ccache
Add symlinks so ccache can invoke the compiler, /usr/local/bin is usually in the path before /usr/bin, so that is where we put the symlinks. The CROSS_COMPILE environment variable should be empty native builds, it could be something like arm-linux-gnueabihf- for cross-building on a host.
$ cd /usr/local/bin $ ln -s $(which ccache) $(echo $CROSS_COMPILE)gcc $ ln -s $(which ccache) $(echo $CROSS_COMPILE)g++ $ ln -s $(which ccache) $(echo $CROSS_COMPILE)cpp $ ln -s $(which ccache) $(echo $CROSS_COMPILE)c++
Setup environment variables. You may want to add these to your .bashrc file so they are applied for each new shell
$ export CCACHE_DIR=/home/$USER/.ccache $ export CCACHE_HASHDIR=$CCACHE_DIR
Note: To clear the ccache
$ ccache -c
Show commit per author
git shortlog v4.6..v4.7 --author='collabora' -nse
or without -nse to see the patches
git shortlog v4.6..v4.7 --author='collabora'
How do I “git blame” a deleted line?
git log -S <string> path/to/file
Show commit per signed-off when author is different
git shortlog v4.11..v4.12-rc7 --perl-regexp --author='^((?!Enric Balletbo i Serra <enric.balletbo@collabora.com>).*)$' --grep "Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com>"
Prepend all commit messages in interactive rebase
git -c core.editor='sed -i "1s/^/PREFIX: /"' -c sequence.editor=vim rebase -i abcdef
Creating and alias to tag commit FROMLIST
git config --global alias.tag-fromlist "-c core.editor=\"sed -i '1s/^/FROMLIST: /'\" -c sequence.editor=vim rebase -i"
Then, run with:
git tag-fromlist <commit sha>
Adding Reviewed-by and Acked-by Tags with Git
How download complete patch series from patchwork?
https://www.collabora.com/news-and-blog/blog/2019/04/18/quick-hack-git-pw/
or the old way
i.e Get the list of patches
pwclient list -w <submitter> -s New "<search-string>"
i.e Get the list of patches and apply the patches
pwclient list -w <submitter> -s New -f %{id} "<search-string>" | egrep '^[0-9]' | xargs pwclient git-am
