- System Requirements
-
Take some recent Linux system to build the kernel and applications.
To minimize the amount for the necessary test hardware/software environment we use Qemu as a system emulator. This enables us to test our kernel without rebooting the currently running operating system or having another test machine available.
- Skills
-
You should be familiar with a recent Linux system, navigating
through the file system using a shell, editor, make etc.
- Build
-
The following steps will create the kernel binary and additional user-level programs.
-
Download and extract the source code to a source directory.
-
Create and switch to the build directory.
-
Link/Copy the Makefile from the source directory to the build directory.
-
Change the value of the variale femto_SOURCE_DIR to the path of your source directory.
-
Build the kernel and applications using make.
The automatic build process creates the kernel: kernel/femto and some tiny applications user/dump ...,
A bootable CDROM image femto.iso contains a bootloader that starts the kernel.
- Run
-
Boot end execute the kernel with QEMU using the following command:
qemu -boot d -cdrom femto.iso -serial stdio -monitor stdio
