While Coreboot contains and uses nonfree software, it is being reused by several boot distributions like GNU Boot (100%free), Canoeboot (100%free), Libreboot (now ships free and nonfree software). 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.

Some patches were sent on the GNU Boot mailing list as well so it might be easier to understand what needs to be upstreamed with these ones as they may also requires patches in GRUB for instance. The E6400 is also supported by Coreboot and its status is mentioned in the commits. So someone would need to test it with the stock Coreboot to understand what payloads work fine, and also test the dock and other untested hardware.

== Adding newer computers in Coreboot, GNU Boot or Canoboot ==
 +
 
 +
This section is for listing computers that were never supported by Coreboot or by GNU Boot or Canoboot, 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).

The GNU Boot project tries to use the least amount of patching on top of upstream projects, so it's a good start as we start with less patches to look at, even if some of them are not strictly necessary (and could be simply removed by sending a patch to GNU Boot).

In addition there are two patch for flashrom to enable installing GNU Boot or Canoeboot on GM45 Thinkpads without disassembling the laptop. They are needed otherwise the flash chip are not detected. Since the flash chip have different IDs it's not possible to remove the need of the patches by trying to not read/write the whole flash.

Introduction

While Coreboot contains and uses nonfree software, it is being reused by several boot distributions like GNU Boot (100%free), Canoeboot (100%free), Libreboot (now ships free and nonfree software). 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 GNU Boot or Canoboot. 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, older versions of Libreboot or GNU Booot at some point, and that can or could have been added to GNU Boot or Canoboot mostly as-is.

  2. ↑ In Coreboot src/mainboard/intel/d510mo/Kconfig/Kconfig uses NORTHBRIDGE_INTEL_PINEVIEW, and "This generation of the Atom was codenamed Pineview, which is used in the Pine Trail platform. Intel's Pine Trail-M platform utilizes an Atom processor (codenamed Pineview-M) and Platform Controller Hub (codenamed Tiger Point)." from https://en.wikipedia.org/wiki/Pineview_(microprocessor)#Second_generation_cores

Computers not merged (yet) in Coreboot

This section is for listing computers that work with patches that are not yet in Coreboot. Finishing the patches, getting them reviewed and accepted would make it easier to support such computers in 100% free boot software distributions.

Original vendors Model(s) Chipset family Patch status Patch link Comments
Dell Optiplex 780 (MT + USFF variants) Work in progress https://review.coreboot.org/c/coreboot/+/84880
  • Normally it should work without nonfree software
  • Already supported by Canoeboot with the "Work in progress" patch.
Dell

Probably based on the E6400 code:

  • Latitude E4300
  • Latitude E6400 XFR ?
  • Latitude E6400 ATG ?
  • Normally it should work without nonfree software
  • Already supported by Canoeboot, probably with out of tree patches. Some patches were sent on the GNU Boot mailing list as well so it might be easier to understand what needs to be upstreamed with these ones as they may also requires patches in GRUB for instance. The E6400 is also supported by Coreboot and its status is mentioned in the commits. So someone would need to test it with the stock Coreboot to understand what payloads work fine, and also test the dock and other untested hardware.

Adding newer computers in Coreboot, GNU Boot or Canoboot

This section is for listing computers that were never supported by Coreboot or by GNU Boot or Canoboot, 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).

 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.

GNU Boot patches

The GNU Boot project tries to use the least amount of patching on top of upstream projects, so it's a good start as we start with less patches to look at, even if some of them are not strictly necessary (and could be simply removed by sending a patch to GNU Boot).

Patch Type

In addition there are two patch for flashrom to enable installing GNU Boot or Canoeboot on GM45 Thinkpads without disassembling the laptop. They are needed otherwise the flash chip are not detected. Since the flash chip have different IDs it's not possible to remove the need of the patches by trying to not read/write the whole flash.
