Kernel modules

Pre-req

You need the following packages to build:

gcc-12 dpkg-dev dh-python stgit python3-jinja2 kernel-wedge quilt flex bison cpio quilt libelf-dev libssl-dev bc

Build kernel

Download the sonic-linux-kernel repository and check out the branch/commit you want to build. Build using make, some platforms require options but defaults seem fine for a normal amd64 switch.

Build platform modules

In this example we will build the modules platform/marvell-teralynx/sonic-platform-modules-cel/silverstone-x/modules.

make -C [..]/sonic-linux-kernel/linux-*/debian/build/build_amd64_none_amd64 \
  M=[..]/sonic-buildimage/platform/marvell-teralynx/sonic-platform-modules-cel/silverstone-x/modules
