The tint payload.

tint is a small curses-based game.

We have ported this game to libpayload so it can now be used as a coreboot payload.

Building

libpayload

The tint payload uses libpayload,which is in the coreboot tree:

$ svn co svn://coreboot.org/coreboot/trunk

tint

You can then get tint itself, patch it, and build it:

$ cd coreboot/payloads
$ wget http://ftp.debian.org/debian/pool/main/t/tint/tint_0.03b.tar.gz
$ tar xfvz tint_0.03b.tar.gz
$ cd tint-0.03b
$ svn export svn://coreboot.org/coreboot/trunk/payloads/external/tint/libpayload_tint.patch
$ patch -p1 < libpayload_tint.patch
$ make

The file tint.elf is your final payload which you can use with coreboot (v2 or v3), either on real hardware or in a QEMU image.

coreboot

Finally, you have to build coreboot (v4 in this example) with tint as payload:

$ cd ../..
$ make menuconfig

Now enter the Payload menu and select Payload type and then An ELF executable payload file. Now exit the menu, save your settings, and build coreboot:

$ make

The file build/coreboot.rom (or build/bios.bin) is your final coreboot v3 image, which also contains the tint payload.

Running tint in QEMU

For running the coreboot+libpayload+tint image in QEMU, you need a patched version of vgabios-cirrus.bin in your build directory first:

$ cd build
$ wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip
$ unzip Vgabios-cirrus.zip
$ cd ..

You can now run tint in QEMU:

$ qemu -L build -hda /dev/zero -serial stdio

Ready-made QEMU image

Please follow these instructions if you want to try out coreboot and tint in QEMU.
