The Ada Monolithic kernel Project -------------------------------------------------------------------------------- Introduction -------------------------------------------------------------------------------- This source is based on the Ada Bare Bones tutorial from http://wiki.osdev.org/Ada_Bare_bones. The aims of this project are twofold: 1) to solidify operating system development knowledge gained by implementing a simple monolithic kernel and a few drivers. 2) To provide the basis for an educational operating system which can be used in OS classes by stripping out the various components so they can be re-implemented by the students. -------------------------------------------------------------------------------- Prerequisites -------------------------------------------------------------------------------- You will need an Ada compiler, we will be using the system compiler under Debian. If there are any changes you need to make to get it to work on a different OS we will list them here. To test using make QEMU, you will need GRUB 2 installed for the grub-mkrescue (GRUB 2 should be installed if you're on a modern distribution) command. This command also uses xorriso - which I had to install separately. Under Debian: $ sudo apt-get install qemu xorriso -------------------------------------------------------------------------------- Instructions -------------------------------------------------------------------------------- 1) Build the RTS: for f in "ada.ads" "a-unccon.ads" "a-uncdea.ads" "gnat.ads" "g-souinf.ads" \ "interfac.ads" "s-atacco.adb" "s-atacco.ads" "s-maccod.ads" "s-stoele.adb" \ "s-stoele.ads" do ln -s `pwd`/rts/src/$f `pwd`/rts/boards/i386/adainclude/$f done gnatmake -Pgnat.gpr -XBoard=pc 2) Build the kernel: make 3) Test: make qemu -------------------------------------------------------------------------------- Bugs -------------------------------------------------------------------------------- None at present. -------------------------------------------------------------------------------- Licence -------------------------------------------------------------------------------- 2-clause simplified BSD.
