Group: Hardware/Upstream projects/Coreboot

Revision as of 23:49, 24 December 2022

Introduction

While Coreboot contains and uses nonfree software, it is the upstream for Libreboot. It also contains a wide variety of projects.

This means that we have to care about the upstream status of computers that can be supported by Libreboot. And we also need FSDG compliant ways to be able to use and package the tools that are developed in the Coreboot source tree.

Tools

FSDG Distribution	Package	Tools
Guix	ifdtool	ifdtool
Guix	intelmetool	intelmetool
Guix	me-cleaner	me_cleaner.py
Parabola	libreboot-utils	bincfg bucts cbfs-compression-tool cbfstool cbmem cse_fpt cse_serger demefactory ectool elogtool fmaptool ich9deblob ich9gen ich9show ifdtool ifittool ifwitool intelmetool inteltool me_cleaner.py nvramtool rmodtool spkmodem-recv superiotool
Trisquel 10 (nabia)	nvramtool	nvramtool

Computers status

Original vendors	Model(s)	Maintainer(s)	Status
Acer	G43T-AM3	Unmaintained	Seem fine. Also has native GPU initialization.
Apple	iMac 5,2 Macbook 1,1 Macbook 2,1	Evgeny Zinoviev	No more free software GPU init in 4.18 but the i915 driver seem to be able to initialize the GPU for the X60^[1] Looks fine otherwise
Asus	KCMA-D8	Unmaintained	Removed from Coreboot
Asus	KFSN4-DRE	Unmaintained	Removed from Coreboot
Asus	KGPE-D16	Unmaintained	Removed from Coreboot
Gigabyte	D945GCLF2D	Not mentioned upstream, Similar to the Intel D945GCLF, "reported working by a user" on the Libreboot website
Gigabyte	GA-G41M-ES2L	Damien Zammit	Seem fine. Also has native GPU initialization.
Google	Veyron_Jaq (Haier Chromebook 11) Veyron_Jerry (Hisense Chromebook 11) Veyron_Mighty (Haier Chromebook 11(edu)) Veyron_Minnie (ASUS Chromebook Flip C100) Veyron_Speedy (ASUS C201 Chromebook)	Unmaintained	Still in Coreboot 4.18
Intel	D410PT D510MO	Damien Zammit	No more free software GPU init in 4.18 but the i915 driver seem to be able to initialize the GPU for the X60^[1] Looks fine otherwise
Intel	D945GCLF	Unmaintained	Seem fine. Also has native GPU initialization.
Lenovo	Thinkpad R60 (with Intel GPU only) Thinkpad T60 (with Intel GPU only) ~~Thinkpad T60p~~^[2] ~~Thinkpad Z61t~~^[3]	Alexander Couzens	No more free software GPU init in 4.18 but the i915 driver seem to be able to initialize the GPU for the X60^[1] Looks fine otherwise
Lenovo	Thinkpad R400 Thinkpad R500 Thinkpad T400 Thinkpad T500 Thinkpad W500	Alexander Couzens	Seem fine If UART is enabled in the Coreboot 4.18 build configuration, the computer needs the dock to boot. It works fine without UART.
Lenovo	Thinkpad T400s^[4]	Not mentioned upstream, might be similar to the T400. DRIVERS_LENOVO_WACOM is not in src/mainboard/lenovo/t400/Kconfig though.
Lenovo	Thinkpad X60 Thinkpad X60s Thinkpad X60 Tablet	Alexander Couzens	No more free software GPU init in 4.18 but the i915 driver seem to be able to intialize the GPU^[1] Boots fine otherwise
Lenovo	Thinkpad X200 Thinkpad X200s Thinkpad X200 Tablet ThinkPad X301	Stefan Ott	Seem fine

↑ ^1.0^1.1^1.2^1.3 The test was done with an X60 without internal display, an external display, Coreboot 4.18 without nonfree microcode and Guix with linux-libre 6.0.10-gnu
↑ Cannot be supported because only ATI GPUs are available. Reference: https://www.thinkwiki.org/wiki/Category:T60p /!\ Add blocker recommended for this link.
