Summary:
Here an RPM specfile and surrounding machinery is added to build an
FBOSS-compatible Linux kernel from vanilla Linux sources which is
compatible with CentOS. On top of this reference configuration,
additional local changes from `fboss-local-overrides.yaml` are applied
prior to building.
To use, inside an FBOSS build container, run:
# fboss-image/kernel/scripts/build_kernel.sh 6.4.3 out
...
Kernel RPM build complete!

I wonder if my latest commit was missed in the merge as I see the "This pull request is closed, but the raghav.oss-kernel branch has unmerged commits". |
