<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>.
</p>
<ul>
<li>Did we forget to mention that this is from git?</li>

<h2 id="critical_tasks">
Critical tasks for future release
</h2>
<ul>
<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.
</li>
<li>
X60: <b>ACPI PCC Probe Failed</b> message on linux-libre 3.19 and higher. Fix it.
<a href="https://bugzilla.kernel.org/show_bug.cgi?id=93171">Preliminary bug report (kernel, linux)</a>
-- the error message is probably not the issue, but something else. do a bisect of linux.
Also, does the issue still occur on lenovobios? pstuge said <a href="http://biosbits.org/">http://biosbits.org/</a>
</li>
<li>
X200: only framebuffer graphics work. This is fine, since it's what most people use,
but text-mode graphics initialization is currently broken, which means that
memtest86+ will require serial output or ehci debugging.
</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>
<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>
Add proper GS45 raminit for enabling all X200S and X200 Tablets to work properly. See <a href="hcl/x200.html#x200s_raminit">hcl/x200.html#x200s_raminit</a>
</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>
ThinkPad R400/R500/T400/T400S/T500: see <a href="hcl/x200.html#new_targets">hcl/x200.html#new_targets</a>.
<ul>
<li>T400S might be GS45, and it might be using a wson-8 form factor for the flash chip.</li>
</ul>
</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>

<h2 id="other_tasks">
other tasks
</h2>
<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>port acer aspire 5738 to coreboot (gm45)? (and then libreboot). EC is the main blocker (no support in coreboot yet)</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>,

He also uses the sigrok logic analyzer (free/libre):

</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>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.</li>
<li>linux 3.18 broke acpi brightness on i945. Libreboot reverted to legacy brightness for now. Look into why it
broke on 3.18 (do a git bisect).</li>
<li>
Look at vortex86ex boards. See <a href="http://libreboot.org/vortex86ex">http://libreboot.org/vortex86ex</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>
