Kernel Installation

This page describes a simple workflow to prepare dependencies, configure the RAMOS kernel, build it, and install it inside the guest image.

Get Source Code

git clone https://github.com/ramryder-project/ramos.git
cd ramos

Prepare

Install the required build dependencies first.

Run all remaining commands in the kernel source tree:

sudo apt-get update
sudo apt-get install build-essential libncurses5 libncurses5-dev bin86 kernel-package libssl-dev bison flex libelf-dev dwarves

Configure Kernel

Start from the current system configuration:

cp /boot/config-$(uname -r) .config
make olddefconfig

Then open the configuration menu:

make menuconfig

In make menuconfig, enable the following RAMOS options under General setup:

• RAMOS NUMA abstraction support
• RAMOS debug mode (optional, for more verbose log output)

Reference example:

Build and Install

Use the following commands for a full kernel build and installation:

make -j$(nproc)
make -j$(nproc) modules
sudo make INSTALL_MOD_STRIP=1 modules_install
sudo make install

Then reboot the VM and select new kernel Linux 6.3.0-ramos+.

Note that INSTALL_MOD_STRIP=1 removes debug symbols from kernel modules. This reduces build time and saves storage space, but you may want to keep debug symbols if you plan to use gdb.

Boot Updates

These steps are optional because make install already handles the required boot updates in most cases. The commands below are kept here for reference in case the new kernel does not appear after reboot.

update-initramfs -c -k [kernel version full name]
update-grub
