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

tint

First, get tint itself and patch it:

$ git clone http://review.coreboot.org/p/coreboot.git
$ cd coreboot/payloads/external/tint
$ wget http://snapshot.debian.org/archive/debian-archive/20110127T084257Z/debian/pool/main/t/tint/tint_0.03b.tar.gz
$ tar xfvz tint_0.03b.tar.gz
$ cd tint-0.03b
$ patch -p1 < ../libpayload_tint.patch

Then, build libpayload:

$ cd ../../../libpayload
$ make menuconfig
$ make
$ make install

The libpayload directory has to be in the tint-0.03b directory:

$ cd ../external/tint/tint-0.03b
$ ln -s ../../../libpayload/install/libpayload libpayloadbin

Finally, build tint itself:

$ cd ..
$ make

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

coreboot

Finally, you have to build coreboot with tint as payload:

$ cd ../../../..
$ cp ../tint/tint-0.03b/tint payload.elf
$ make menuconfig

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

$ make

The file build/coreboot.rom is your final coreboot 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, and you also need to rename or copy coreboot.rom to bios.bin:

$ cd build
$ mv coreboot.rom bios.bin
$ 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 QEMU#coreboot_v3_.2B_libpayload_.2B_tint these instructions if you want to try out coreboot and tint in QEMU.
