Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
Today, Libreboot gains its *first* desktop machine for nearly 2 years. The
|
||
|
|
last one added was Acer G43T-AM3.
|
||
|
|
|
||
|
|
You can learn more about this on the [HP Elite 8200 SFF Libreboot installation
|
||
|
|
and hardware information page](../docs/hardware/hp8200sff.md).
|
||
|
|
|
||
|
|
The patch for Libreboot was done, courtesy of Riku Viitanen, IRC nick `Riku_V`
|
||
|
|
on Libreboot IRC. It's quite a nice Intel Sandybridge platform, with all libre
|
||
|
|
initialisation on the coreboot side, and Libreboot's build system automatically
|
||
|
|
runs `me_cleaner` while building for this board.
|
||
|
|
|
||
|
|
This board is significant because it's relatively simple to flash, cheap, and
|
||
|
|
readily available on merchant sites such as eBay. Desktop support has
|
||
|
|
traditionally been much weaker in Libreboot, and this is something that
|
||
|
|
should (can, and will) change.
|
||
|
|
|

|
|
HP EliteBook 2560p (laptop)
|
||
|
|
------------------
|
||
|
|
|
||
|
|
Riku is also interested in adding HP EliteBook 2560p support in Libreboot.
|
||
|
|
Coreboot has support for that board. For *that* board, I committed this
|
||
|
|
patch in a branch of Libreboot, to make handling EC firmware easier for Riku:
|
||
|
|
|
||
|
|
<https://browse.libreboot.org/lbmk.git/commit/?h=blobutil_kbc1126_ec&id=b9ee4e79c33365ede01fb7d2a0d5c8f3c1a1928c>
|
||
|
|
|
||
|
|
I initially wrote the logic in that patch as part of another experimental
|
||
|
|
branch of Libreboot, adding HP Elitebook 8560w (does not boot yet).
|
||
|
|
|
||
|
|
If my EC download script works for Riku, and 2560p support confirmed working
|
||
|
|
when Riku tests it, then both of them shall by merged into Libreboot's master
|
||
|
|
branch. The EC firmware is not on a separate IC, for that machine; instead,
|
||
|
|
it must be handled during the coreboot build process, for insertion into the
|
||
|
|
main boot flash. This is actually *better*, for similar reasons as explained
|
||
|
|
in the Libreboot [blobs reduction policy](policy.md), because it makes the EC
|
||
|
|
firmware easier to replace with libre code (based on reverse engineering,
|
||
|
|
perhaps).
|
||
|
|
|
||
|
|
Dell Optiplex 7020/9020 probably soon (testing needed)
|
||
|
|
-------------------------------------
|
||
|
|
|
||
|
|
I've purchased Dell Optiplex 7020 and 9020 workstations (Haswell gen), which is
|
||
|
|
available for coreboot with this gerrit patch:
|
||
|
|
|
||
|
|
<https://review.coreboot.org/c/coreboot/+/55232/>
|
||
|
|
|
||
|
|
Libreboot will eventually support *all* coreboot targets.
|
||
|
|
|
||
|
|

---------------------------------
|

|
|
|

|
|
Libreboot has the following documentation available:
|
||
|
|
|
||
|
|
* [lbmk maintenance manual](../docs/maintain/) (build system documentation)
|
||
|
|
* [porting guide](../docs/maintain/porting.md) (largely Intel-centric, at
|
||
|
|
the time of writing this post)
|
||
|
|
|
||
|
|
Riku's work was inspired by reading these. The guides themselves are also in
|
||
|
|
need of constant maintenance and improvement, relative to the changes in
|
||
|
|
Libreboot.
