This is the SLE 15 SP3 RT kernel branch.
It is the above persons’ responsiblity for checking in this kernel to the build system, anyone else who wishes to do so, needs to get permission from them first.
If there are any questions about this branch, please contact the above mentioned maintainer.
To install prebuilt kernel from this branch run
zypper ar -f https://download.opensuse.org/repositories/Kernel:/SLE15-SP3-RT/standard \ Kernel:SLE15-SP3-RT zypper in --from Kernel:SLE15-SP3-RT kernel-default
Please note: The packages are built for the distribution they are targetting. In case of the vanilla and linux-next branches, this is the latest released openSUSE version. While the packages should work fine on fine on a distribution that is slightly newer or slightly older, installing ancient kernels on the latest distributions is asking for trouble. Same goes for the opposite case, e.g. installing the Factory kernel on SLES 9.
There are two SUSE Kernel repositories. Development happens in the kernel-source git repository. This tree is a quile-like series of patches against the upstream kernel, plus spec files and various scripts. You can clone it with
git clone https://github.com/openSUSE/kernel-source -b SLE15-SP3-RT
If you just want to hack on the sources and do not need to package the kernel, use the kernel git repository. This one has the same layout as the upstream kernel. Clone command:
git clone https://github.com/openSUSE/kernel -b SLE15-SP3-RT
