Branch and tag names

For each tagged upstream (linus, stable) release we have branch which includes our local commits:

Upsteam Tag	Our branch
v5.10.100	linux-5.10.100-mpi
v5.10.101	linux-5.10.101-mpi
e.t.c.	e.t.c.
v5.17-rc5	linux-5.17-rc5-mpi
v5.17-rc4	linux-5.17-rc4-mpi
v5.17-rc3	linux-5.17-rc3-mpi
v5.17-rc2	linux-5.17-rc2-mpi
v5.17-rc1	linux-5.17-rc1-mpi
v5.17	linux-5.17-mpi
v5.17.1	linux-5.17-1-mpi
v5.17.2	linux-5.17-rc4-mpi
e.t.c.	e.t.c.
v5.18-rc1	linux-5.18-rc1-mpi
v5.18-rc2	linux-5.18-rc2-mpi
v5.18-rc3	linux-5.18-rc3-mpi
e.t.c.	e.t.c.

These branches are created automatically (for some Kernel series) whenever a new release is published upstream.

Currently this is done for series 5.10 (since 5.10.100), 5.17 (since 5.17-r5) and 5.18.

To build a kernel with bee, we first create a tag in this repository, e.g. mariux-5.10.110-433 for linux-5.10.110-433.bee.

Note: Tags of the form vVERSION-mpi.0 are obsoleted. Only These tags have been used in bee files and are kept: v5.10.103-mpi.0, v5.10.107-mpi.0, v5.10.108-mpi.0, v5.10.109-mpi.0

Some useful commands

List our branches:

git branch -a | grep -- -mpi

Show our commits:

git log --oneline --no-merges --no-decorate mariux64/linux-VERSION-mpi ^vVERSION

Build a kernel

git checkput linux-VERSION-mpi
cp  config-mpi .config
make olddefconfig
make -j $(nrpoc)

Install and select it as a test kernel for the next reboot:

Once:

cat >>install.sh <<EOF
#! /bin/bash
make modules_install
cp ./arch/x86/boot/bzImage /boot/bzImage.test
mxgrub bzImage.test
EOF
chmod +x install.sh

Then:

sudo ./install.sh

Change the config

loop:

make menuconfig              # make your changes
make savedefconfig
diff config-mpi defconfig    # review your changes

when done:

cp defconfig config-mpi
git commit -v config-mpi

Create a new build tag for a bee file

git checkout linux-VERSION-mpi
git tag mariux-VERSION-BUILDNUMBER
git push mariux64 mariux-VERSION-BUILDNUMBER

Cherry-pick config changes from another mpi branch

git checkout linux-VERSION-mpi

For each commit:

git cherry-pick XXXXXXX        # if this fails, see below
cp config-mpi .config && make olddefconfig && make savedefconfig && diff config-mpi defconfig
cp defconfig config-mpi && git commit --amend config-mpi      # only if there were differences

If cherry-pick fails:

git restore -s HEAD config-mpi && cp config-mpi .config && make olddefconfig
make menuconfig               # do it manually
make savedefconfig && cp defconfig config-mpi && git add config-mpi && git cherry-pick --continue

When done:

git push mariux64
