Tint

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

Under Standard Libraries choose Tinycurses instead of the default PDCurses as the Curses implementation as building Tint fails with the PDCurses implementation. Then exit the Kconfig menu and say Yes to saving the config.

$ 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.
