<h2>
Git. No changelog!
</h2>
<p>
This version of libreboot is from git. It is not a stable release!
If you are using a snapshot (tarball), you can find a file included called <b>commitid</b>
which tells you what git revision it is from the libreboot git repository. If this is not
a snapshot, then you have cloned libreboot, so you can simply run <b>git log</b>.

Tasks for future release
</h2>
<ul>
<li>
Documentation improvements:
<ul>
<li>
Convert documentation to Sphinx/ReST
See <a href="http://projects.mtjm.eu/work_packages/5">http://projects.mtjm.eu/work_packages/5</a>
and <a href="http://projects.mtjm.eu/work_packages/12">http://projects.mtjm.eu/work_packages/12</a>
</li>
<li>
<b>
Maintainence manual. How to contribute to libreboot.
See <a href="http://projects.mtjm.eu/work_packages/11">http://projects.mtjm.eu/work_packages/11</a>
</b>
</li>
</ul>
</li>
<li>
Make libreboot (all of it!) build reproducibly. This is very important.
See <a href="http://projects.mtjm.eu/work_packages/16">http://projects.mtjm.eu/work_packages/16</a>.
</li>
<li>
Add information from hw registers on all boards. See
<a href="http://projects.mtjm.eu/work_packages/15">http://projects.mtjm.eu/work_packages/15</a>
</li>
<li>
Reduce the size of libreboot releases.
See <a href="http://projects.mtjm.eu/work_packages/19">http://projects.mtjm.eu/work_packages/19</a>
<ul>
<li>
Proposal: unify ROM images (don't duplicate).
See <a href="http://projects.mtjm.eu/work_packages/20">http://projects.mtjm.eu/work_packages/20</a>.
</li>
</ul>
</li>
<li>
<a href="http://projects.mtjm.eu/work_packages/13">Port to as many GM45 laptops as possible</a>
<ul>
<li>
add roda rk9 support (contact nico to ask for more details about hw).
This is GM45 but these machines do not have a descriptor (no ME), should be easy
</li>
<li>
ThinkPad T400: <a href="http://projects.mtjm.eu/work_packages/41">http://projects.mtjm.eu/work_packages/41</a>
</li>
<li>
ThinkPad T500: <a href="http://projects.mtjm.eu/work_packages/42">http://projects.mtjm.eu/work_packages/42</a>
</li>
<li>
ThinkPad R500: <a href="http://projects.mtjm.eu/work_packages/43">http://projects.mtjm.eu/work_packages/43</a>
</li>
<li>
port acer aspire 5738 to coreboot (gm45)? (and then libreboot). EC is the main blocker (no support in coreboot yet).
ME isn't an issue, because its GM45 so it could be removed (it looks like this machine might also be shipped in
non-descriptor mode by default, like the roda rk9).
Search <b>jv50 block diagram filetype:pdf</b> for schematics.
(jv50 is written on the board); noone seems to have found any documentation for the EC chip, but
maybe it could be sufficiently reverse engineered via serialice and ectool.
</li>
<li>
T400S and X301. These both seem to be GS45. X301 uses only the low-performance mode CPUs, so raminit
is the main blocker there. They both probably use WSON-8 flash chips.
</li>
<li>
Add proper GS45 raminit for enabling all X200S and X200 Tablets to work properly. (maybe other machines)
See <a href="hcl/x200.html#x200s_raminit">hcl/x200.html#x200s_raminit</a>
</li>
</ul>
</li>
<li>
Fix these issues on GM45/GS45 targets:
<ul>
<li>
X200: text-mode is broken. only framebuffer graphics work.
</li>
</ul>
</li>
<ul>
Related to MemTest86+:
<ul>
<li>Memtest86+ is currently broken in text-mode. investigate</li>
<li>
Todo: modify memtest86+ to work with libpayload (coreboot framebuffer) and delete all the text-mode ROM images.
See <a href="http://projects.mtjm.eu/work_packages/17">http://projects.mtjm.eu/work_packages/17</a>
</li>
<li>Make memtest86+ build using coreboot's own crossgcc toolchain.</li>
</ul>
</ul>
<ul>
Related to GRUB:
<ul>
<li>Make GRUB build using coreboot's own crossgcc toolchain</li>
</ul>
</ul>
<li>
Look into the possibility of expanding libreboot to support non-coreboot systems. (u-boot, for instance).
Currently, libreboot presents itself as a deblobbed coreboot distribution. There are other systems out there
that use other firmware, such as u-boot, which libreboot could theoretically support. This would mean that
the build scripts know how to build things other than just coreboot/grub.
<ul>
<li>Allwinner A10 (ARM) SoCs</li>
<li>PMON?</li>
<li>barebox (u-boot derivative)</li>
<li>etc</li>
</ul>
</li>
<li>
Set up a routine (project-wise) for testing each machine with the latest kernel version.
See <a href="http://projects.mtjm.eu/work_packages/22">http://projects.mtjm.eu/work_packages/22</a>
and <a href="http://projects.mtjm.eu/work_packages/21">http://projects.mtjm.eu/work_packages/21</a>
</li>
<li>
Improve the deblobbing scripts (see <a href="http://projects.mtjm.eu/work_packages/40">http://projects.mtjm.eu/work_packages/40</a>)
<ul>
<li>
.spd.hex files. These aren't blobs? Don't remove them? (in coreboot). See deblob script.
Categorize blobs and non-blobs more clearly, explaining what they are for
and why they are (or are not) blobs.
</li>
</ul>
</li>
<li>
i945: fix linux (if possible). VBT. http://www.coreboot.org/pipermail/coreboot/2014-June/078104.html
http://www.coreboot.org/pipermail/coreboot/2014-June/078105.html
This is talking about without native init / oprom. Paul reported it, look into it.
i945 currently lacks fake_vbt tables.
</li>
<li>
Make ich9gen/ich9deblob portable. They both rely extensively on bitfields, and they assume
little-endian; for instance, mapping a little endian file directly to a struct, instead
of serializing/deserializing. Re-factor both utilities and make them fully portable.
See <a href="http://projects.mtjm.eu/work_packages/18">http://projects.mtjm.eu/work_packages/18</a>
</li>
<li>
Fix these issues on i945 targets (X60/T60/macbook21)
<ul>
<li>
linux 3.18 broke acpi brightness on i945 (X60/T60). Libreboot reverted to legacy brightness for now. Look into why it
broke on 3.18 (do a git bisect).
</li>
<li>
i945: fix VRAM size (currently 8MB. should be 64MB).
See <a href="future/index.html#i945_vram_size">future/index.html#i945_vram_size</a>.
</li>
<li>
i945: Linux 3.19 doesn't boot. (probably affects T60/macbook21).
<a href="https://bugzilla.kernel.org/show_bug.cgi?id=93171">Preliminary bug report (kernel, linux)</a>
-- bogus. Based on earlier immature reports.
-- the error message is probably not the issue, but something else. do a bisect of linux.
Also, does the issue still occur on lenovobios? (no, they don't, according to Paul Menzel)
pstuge said <a href="http://biosbits.org/">http://biosbits.org/</a>
patricg says https://wiki.ubuntu.com/HardwareEnablementTeam/Documentation/FirmwareTestSuiteLive
</li>
<li>
Fix remaining incompatible LCD panels in native graphics on T60.
See <a href="future/index.html#lcd_i945_incompatibility">future/index.html#lcd_i945_incompatibility</a>.
</li>
</ul>
</li>
<li>
Look into those machines:
<ul>
<li>
ThinkPad X201 - ME ignition is an issue. Watchdog for ME is an issue. Might be possible to disable watchdog in the flash descriptor
(soft straps).
</li>
<li>
T410S is supported but not yet merged. This uses the same chipset as the X201.
<a href="http://review.coreboot.org/#/c/7975/">http://review.coreboot.org/#/c/7975/</a>
has the patch. This should be tested by someone and should ideally be merged in coreboot. pecg has one. help him.
</li>
<li>
This page contains a list of basically every thinkpad that would ever be a candidate for libreboot:
<a href="http://psref.lenovo.com/WithdrawnBook">http://psref.lenovo.com/WithdrawnBook</a> -
take a look at <a href="http://www.lenovo.com/psref/pdf/ltwbook_2013.pdf">this PDF</a>.
</li>
<li>
Lenovo G505S - might need video bios and microcode updates. These would have to be removed and/or replaced to be in libreboot
<a href="https://github.com/alterapraxisptyltd/lenovo-g505s">https://github.com/alterapraxisptyltd/lenovo-g505s</a>.
It's AMD (not Intel) based on the same design as the HP Pavillion 1035DX. No ME/AMT to worry about!
<a href"http://www.coreboot.org/User_talk:MrNuke/LTS_Candidates">http://www.coreboot.org/User_talk:MrNuke/LTS_Candidates</a>
and <a href="http://www.coreboot.org/Board:hp/pavilion_m6_1035dx#Native_graphics_init">http://www.coreboot.org/Board:hp/pavilion_m6_1035dx#Native_graphics_init</a>
</li>
<li>
F2A85-M and E350M1 (libreboot_*_headless.rom). Test openatom. SMU firmware is a problem. XHCI firmware is a problem.
</li>
</ul>
</li>
<li>
Commit 26ca08caf81ad2dcc9c8246a743d82ffb464c767 in coreboot, see the while (1) loop that
waits for the panel to power up on i945. This is an infinite loop if the panel doesn't power up.
Fix it. Also, are there panels that don't power up? Test this, and fix it.

work with mrnuke on getting info about vultureprog PLCC flashing into libreboot. Libreboot needs
server boards. <a href="https://github.com/mrnuke/vultureprog">https://github.com/mrnuke/vultureprog</a>,

</li>
<li>Add cubieboard SPI flashing instructions to libreboot.
<a href="https://github.com/mrnuke/coreboot/commits/cubie_mmc?author=mrnuke">mrnuke's github page with patches</a>. mrnuke in IRC knows
about the cubieboard</li>
<li>
LUKS key in initramfs: Add Trisquel documentation for docs/gnulinux/encrypted_trisquel.html.
See <a href="http://projects.mtjm.eu/work_packages/39">http://projects.mtjm.eu/work_packages/39</a>
</li>
<li>Adapt linux-libre deblob scripts for use with coreboot. Libreboot is already deblobbed
using its own script, but updating it is still a bit too manual. linux-libre's deblob
scripts do an excellent job and (adapted) will make it much easier to maintain coreboot-libre.</li>
