Group: Hardware/Upstream projects/Coreboot

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.

Computers status

This section is for computers that worked with either Coreboot or Libreboot at some point, and that can or could have been added to Libreboot mostly as-is.

Original vendors	Model(s)	Maintainer(s)	Chipset or microarchitecture family	Status
Acer	G43T-AM3	Unmaintained	Intel G43	Seem fine. Also has native GPU initialization.
Apple	iMac 5,2 Macbook 1,1 Macbook 2,1	Evgeny Zinoviev	Intel I945	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	?	AMD Family 10H	Removed from upstream Coreboot, maintained in the Coreboot 4.11 branch
Asus	KFSN4-DRE	?	AMD Family 10H	Removed from upstream Coreboot, maintained in the Coreboot 4.11 branch
Asus	KGPE-D16	?	AMD Family 10H	Removed from upstream Coreboot, maintained in the Coreboot 4.11 branch
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	Intel I945	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	Intel Tiger Point (Atom chipset)^[2]	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	Intel I945	Seem fine. Also has native GPU initialization.
Lenovo	Thinkpad R60 (with Intel GPU only) Thinkpad T60 (with Intel GPU only) ~~Thinkpad T60p~~^[3] ~~Thinkpad Z61t~~^[4]	Alexander Couzens	Intel I945	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	Intel GM45	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^[5]	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	Intel I945	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	Intel GM45	Seem fine

Adding newer computers in Coreboot and Libreboot

This section is for listing computers that were never supported by Coreboot or by Libreboot, but that may be added relatively easily.

The goal here is to list computers that are similar enough to already supported computers and that could be added without having to add new drivers for specific hardware (like adding support for ATI or Nvidia GPUs) and without getting rid of some existing nonfree software (like the SMU for AMD computers).

Original vendors	Model(s)	Chipset family	Comments
Lenovo	ThinkPad SL300 (with Intel GPU only) ThinkPad SL400 (with Intel GPU only) ThinkPad SL400c ThinkPad SL410 ThinkPad SL500 (with Intel GPU only) ThinkPad SL500c ThinkPad SL510	Intel GM45	According to ThinkWiki these laptops have an Intel GM45. According to ThinkWiki these laptops have an "IdeaPad firmware", which means that "as such some of the ThinkPad specific drivers and features are not supported.". I've made some tests on one of these (Maybe it was the SL410) and thinkpad_acpi was loaded. Though I cound't do dangerous tests on the EC (embedded controller), so I don't know the differences.
