Leah Rowe
|
||||
---------
|
||||
|
||||
**Founder of the Libreboot project, and currently the lead developer.** Leah
|
||||
works on all aspects of Libreboot, such as:
|
||||
|
||||
* General management. Leah handles all outside contributions to Libreboot,
|
||||
reviews pull requests, deals with bug reports, delegates tasks when necessary
|
||||
or desirable. Leah controls the libreboot.srht.site server infrastructure, hosted
|
||||
in her lab (of course it runs Libreboot!)
|
||||
* Leah has the final say on all decisions, taking input via discussion with
|
||||
members of the public, mostly on IRC. Leah oversees releases of Libreboot,
|
||||
and generally keeps the project going. Without Leah, there would be no Libreboot!
|
||||
* The build system (lbmk, short for Libreboot Make). This is the automated build
|
||||
system that sits at the heart of Libreboot; it downloads, patches, configures
|
||||
and compiles the relevant components like coreboot, GNU GRUB and generates
|
||||
the Libreboot ROM images that you can find in release archives.
|
||||
* Upstream work on coreboot, when necessary (and other projects that Libreboot
|
||||
uses). This means also working with people from outside of the Libreboot
|
||||
project, to get patches merged (among other things) on the upstream projects
|
||||
that Libreboot uses
|
||||
* Providing user support on IRC
|
||||
* *Commercial* user support via her company listed
|
||||
on [the suppliers page](/suppliers.md)
|
||||
|
||||
Leah is also responsible for [osboot.org](https://osboot.org/) which is heavily
|
||||
based on Libreboot, but with different project goals.

Andrew Robbins
|
||||
--------------
|
||||
|
||||
Worked on large parts of Libreboot's old build system and related documentation.
|
||||
Andrew joined the Libreboot project as a full time developer during June 2017,
|
||||
until his departure in March 2021.
|
||||
|
||||
I, Leah Rowe, am very grateful to Andrew Robbins for his numerous contributions
|
||||
over the years.
|
||||
Worked on large parts of a more older build system and related documentation.
|
||||
|
||||
Arthur Heymans
|
||||
--------------
|
||||
|
||||
Merged a patch from coreboot into libreboot, enabling C3 and C4 power
|
||||
states to work correctly on GM45 laptops. This was a long-standing issue
|
||||
before Athur's contribution. Arthur also fixed VRAM size on i945 on
|
||||
GM45 systems, allowing maximum VRAM allocation for the onboard GPUs on
|
||||
these systems, another longstanding issue in libreboot.

Damien Zammit
|
||||
-------------
|
||||
|
||||
Maintains the Gigabyte GA-G41M-ES2L coreboot port, which is integrated
|
||||
in libreboot. Also works on other hardware for the benefit of the
|

libreboot project.
|
||||
|
||||
Damien didn't work directly on Libreboot itself, but he worked heavily with
|
||||
Leah Rowe, integrating patches and new board ports into Libreboot, based on
|
||||
Damien's upstream work on coreboot.
|
||||
in GNU Boot. Also works on other hardware for the benefit of the project.
|
||||
|
||||
Denis Carikli
|
||||
-------------
|
||||
|
||||
Based on the work done by Peter Stuge, Vladimir Serbineko and others in
|
||||
the coreboot project, got native graphics initialization to work on the
|
||||
ThinkPad X60, allowing it to be supported in libreboot. Denis gave
|
||||
a lot of advice and helped found the libreboot project.
|
||||
|
||||
Denis was a mentor to Leah Rowe in the early days, when she founded the
|
||||
Libreboot project. A lot of the decision decisions taken, especially with the
|
||||
Libreboot build system (lbmk), were inspired from talks with Denis.
|
||||
|
||||
Denis taught Leah about registers used by Intel GPUs for backlight control. In
|
||||
the early days, the ThinkPad X60 and T60 laptops in Libreboot did not have
|
||||
backlight control working, so the brightness was always 100%. With Denis's help,
|
||||
Leah was able to get backlight controls working by reverse engineering the
|
||||
correct values to write in those registers. Based on this, a simple fix was
|
||||
written in coreboot; however, the fix just wrote directly to the register and
|
||||
didn't work with ACPI based brightness controls. Others in coreboot later
|
||||
improved it, making ACPI-based backlight controls work properly, based on this
|
||||
earlier work.
|
||||
ThinkPad X60, allowing it to be supported in GNU Boot. Also he helped about
|
||||
many different issues with valuable council, e.g. Intel GPUs backlight control.

Jeroen Quint
|
||||
------------
|
||||
|
||||
Contributed several fixes to the libreboot documentation, relating to
|
||||
installing Parabola with full disk encryption on libreboot systems.

Joshua Gay
|
||||
----------
|
||||
|
||||
Joshua is former FSF staff.
|
||||
|
||||
Joshua helped with the early founding of the Libreboot project, in his capacity
|
||||
(at that time) as the FSF's licensing and compliance manager. It was his job to
|
||||
review products sent into to the FSF for review; the FSF has a certification
|
||||
program called *Respects Your Freedom* (RYF) where the FSF will promote your
|
||||
company's products if it comes with all Free Software.
|
||||
|
||||
I, Leah Rowe, was initially just selling ThinkPad X60 laptops with regular
|
||||
coreboot on them, and this included CPU microcode updates. At the time, I didn't
|
||||
think much of that. Joshua contacted me, in his capacity at the FSF, and asked
|
||||
if I would be interested in the FSF's RYF program; I was very surprised that the
|
||||
FSF would take me seriously, and I said yes. This is what started the early
|
||||
work on Libreboot. Joshua showed me all the problems my products had, and from
|
||||
that, the solution was clear:
|
||||
|
||||
A project needed to exist, providing a fully free version of coreboot, without
|
||||
any binary blobs. At the time (and this is still true today), coreboot was not
|
||||
entirely free software and shipped with binary blobs by default. In particular,
|
||||
CPU microcode updates were included by default, on all x86 machines. Working
|
||||
with Joshua who reviewed my work, I created a fully free version of coreboot.
|
||||
At first, it wasn't called Libreboot, and the work was purely intended for my
|
||||
company (at that time called Gluglug) to be promoted by the FSF.
|
||||
|
||||
Joshua used his media connections at the FSF to heavily promote my work, and
|
||||
on December 13th, 2013, the Libreboot project was born (but not called that).
|
||||
Joshua made sure that everyone knew what I was doing!
|
||||
|
||||
A few months later, the name *Libreboot* was coined, and the domain name
|
||||
*libreboot.srht.site* was registered. At that point, the Libreboot project (in early
|
||||
2014) was officially born. Once again, Joshua provided every bit of help he
|
||||
could, heavily promoting the project and he even wrote this article on the FSF
|
||||
website, announcing it:

||||

Klemens Nanni
|
||||
-------------
|
||||
|
||||
Made many fixes and improvements to the GRUB configuration used in
|
||||
libreboot, and several tweaks to the build system.

Made many fixes and improvements to the GRUB configuration used, and several

|
||||
|
||||
Leah Rowe initially helped Klemens get his project, autoboot, off the ground.
|
||||
Autoboot (website autoboot.org) is no longer online, but was a fork of Libreboot
|
||||
with different project goals; in late 2020, Leah Rowe decided to create her
|
||||
own new fork of Libreboot called *osboot*, heavily inspired by Klemens's earlier
|
||||
work. See: <https://osboot.org/>
|
||||
|
||||
The following is an archive of autoboot.org, from when it was online back in
|
||||
2016: <http://web.archive.org/web/20160414205513/http://autoboot.org/> (the
|
||||
autoboot website went offline a few months later, after Klemens abandoned the
|
||||
project)
|
||||
|
||||
Lisa Marie Maginnis
|
||||
-------------------
|
||||
|
||||
Lisa is a former sysadmin at the Free Software Foundation. In the early days of
|
||||
the project, she provided Leah with a lot of technical advice. She initially
|
||||
created Libreboot IRC channel, when Leah did not know how to
|
||||
use IRC, and also handed +F founder status to Leah for the channel. As an FSF
|
||||
sysadmin, it was Lisa's job to maintain a lot of the infrastructure used by
|
||||
Libreboot; at the time, mailing lists on the GNU Savannah website were used by
|
||||
the Libreboot project. Lisa was also the one who originally encouraged Leah to
|
||||
have Libreboot join the GNU project (a decision that was later, rather
|
||||
regrettably, reversed). When Paul Kocialkowski was a member of the project in
|
||||
2016, she helped him get help from the FSF; he was the leader of the Replicant
|
||||
project at the time, which had funding from the FSF, and the FSF authorized him
|
||||
to use some of that funding for his work on Libreboot, thanks to Lisa's
|
||||
encouragement while she worked at the FSF.
|
||||
|
||||
Lisa also stepped in when Leah Rowe missed her LibrePlanet 2016 talk. Leah was
|
||||
scheduled to do a talk about Libreboot, but didn't show up in time. Lisa, along
|
||||
with Patrick McDermott (former Libreboot developer, who was present at that
|
||||
conference) did the talk in Leah's place. The talk was never recorded, but the
|
||||
Free Software Foundation has these photos of that talk on their LibrePlanet
|
||||
website (the woman with the blue hair is Lisa, and the long-haired dude with the
|
||||
moustache is Patrick):

|
||||
|
||||
Fun fact: Patrick is also the lead developer of ProteanOS, an FSF-endorsed
|
||||
embedded OS project: <http://proteanos.com/> (uses BusyBox and Linux-libre)
|
||||
|
||||
Leah Rowe ran *2* LibrePlanet workshops; one in 2015 and another in 2016, while
|
||||
visiting Boston, MA, USA on both occasions to attend these conferences. These
|
||||
workshops were for Libreboot installations. People came to both workshops, to
|
||||
have Libreboot installed onto their computers. As FSF sysadmin, at that time,
|
||||
Lisa provided all of the infrastructure and equipment used at those workshops.
|
||||
Without her help, those workshops would have not been possible.
|
||||
|
||||
When the ASUS KGPE-D16 mainboard (high-end server board) was ported to Libreboot,
|
||||
Leah, working with Timothy Pearson (the one who ported it), shared patches back
|
||||
and forth with Lisa around mid 2016, mostly raminit patches, to get the board
|
||||
running at the FSF offices. This work ultimately lead to a most wonderful
|
||||
achievement:
|
||||
|
||||
The <https://www.gnu.org/> and <https://www.fsf.org/> websites now run on
|
||||
Librebooted ASUS KGPE-D16 based servers, on a fully free GNU+Linux distro. This
|
||||
means that the FSF now has full software freedom for their hosting infrastructure.
|
||||
|
||||
The FSF also provides access to this infrastructure for many other projects
|
||||
(besides GNU projects); for example, Trisquel uses a D16 provided by the FSF
|
||||
for their development server used for building Trisquel releases and testing
|
||||
changes to the Trisquel GNU+Linux distribution. Trisquel is a fully free
|
||||
GNU+Linux distribution, heavily promoted by the FSF.
|
||||
|
||||
Lisa was a strong supporter of Libreboot in the very early days of the project,
|
||||
and her contributions were invaluable. I, Leah Rowe, owe her a debt of gratitude.

the heart of GNU Boot; it downloads, patches, configures and compiles the

you can find in release archives.

discover the existence of a bit in the descriptor for *disabling* the Intel ME

|

|

His initial proof of concept only defined the descriptor, and would do this:
|

|

* Read the default descriptor and GbE regions from a Lenovo X200 ROM (default
|

firmware, not coreboot)

* Generated the 12KiB descriptor+GbE region, based on this, to insert into a

coreboot ROM image.
|
||||
|
||||
In the early days, before Libreboot supported GM45+ICH9M platforms such as
|
||||
ThinkPad X200/T400, you could use those machines but to avoid the Intel ME you
|
||||
had to flash it without a descriptor region. This worked fine in those days,
|
||||
because the ME only handled TPM and AMT on those machines, and the system would
|
||||
work normally, but that Intel Flash Descriptor also handles the Intel GbE NVM
|
||||
region in flash, which is used for the Intel Gigabit Ethernet interface.
|
||||
|
||||
So you either had Intel ME, or no ethernet support. Steve figured out how to
|
||||
disable the Intel ME via 2 toggle bits in the descriptor, and also how to
|
||||
remove the Intel ME region from flash.
|
||||
|
||||
Based on his research, I, Leah Rowe, working alongside Steve, also reverse
|
||||
engineered the layout of the Intel GbE NVM (non-volatile memory) region in the
|
||||
boot flash. This region defines configuration options for the onboard Intel
|
||||
GbE NIC, if present.
|
||||
|
||||
Based on this, I was able to take Steve's initial proof of concept and write
|
||||
the `ich9gen` utility, which generates an Intel Flash Descriptor and GbE NVM
|
||||
region, from scratch, without an Intel ME region defined. It is this tool,
|
||||
the `ich9gen` tool, that Libreboot uses to provide ROM images for GM45+ICH9M
|
||||
platforms (such as ThinkPad X200/T400/T500/W500), with a fully functional
|
||||
descriptor and functional Gigabit Ethernet, but *without* needing Intel
|
||||
Management Engine (ME) firmware, thus making those machines *libre* (the ME
|
||||
is fully disabled, when you use a descriptor+gbe image generated by `ich9gen`).
|
||||
|
||||
With *my* `ich9gen` tool (Steve's tool was called `ich9deblob`), you didn't
|
||||
need a dump of the original Lenovo BIOS firmware anymore! I could not have
|
||||
written this tool, without Steve's initial proof of concept. I worked with him,
|
||||
extensively, for many months. All GM45+ICH9M support (X200, T400, etc) in
|
||||
Libreboot is made possible because of the work he did, back in 2014.

After that, Swift Geek slowly became more involved until he became a full time

but what he lacked in code, he made up for in providing excellent support, both
|

to users and other developers, helping others learn more about technology at a
|

low level.
|

When Swift Geek was a member of the project, his role was largely providing

user support (in the IRC channel), and conducting research. Swift Geek knows a
|

lot about hardware. Swift Geek also did some upstream development on GNU GRUB.
|

ThinkPad mainboards (while looking at the schematics and boardview).
|
