<b><i>"Release"</i></b> means that a new coreboot git revision with substantially different code has been adapted for libreboot.
</p>
<p>
<b><i>"Revision"</i></b> means a modification to an existing release, where the result is insubstantially different from what preceded it.
</p>
<p>
The 1st, 2nd, 3rd and 4th releases were really just older revisions of the 5th release.
For historical reasons (and to avoid confusion), these are still called 'releases' instead of correcting the mistake.

ACPI brightness (tested on X60/T60): left half of screen is darker than the right side, when turning down brightness. Investigate.<br/>
mtjm: I'll send you my very hacky program for changing brightness and PWM frequency, it makes testing easier<br/>
mtjm: git://git.mtjm.eu/i945-pwm.git, exponent = 4, divisor = 0 is what 6731 would do<br/>
Setting exponent 9 and divisor 0 is what libreboot is doing currently (as a modification to 6731)
<ul>
<li>mtjm says: ACPI spec appendix B video extensions documents what IDs do, igd.asl doesn't use them correctly</li>
<li>phcoder says: igd.asl is so broken. Mismatching IDs, listing methods returning garbage, phantom devices. Any one of those is enough to break ACPI spec and windows. We have all 3. On all chipsets.</li>
<li>6731 (currently cherry picked in libreboot) is -2'd at this time of writing 20140824 while phcoder works on improving it. (worked in GNU/Linux, though).</li>
<li><b>A temporary fix (for uneven backlight) is provided in libreboot. Work in coreboot to fix it properly (phcoder says src/northbridge/intel/i945/acpi/igd.asl needs re-written)</b></li>

<li>
There are issues with i945 text mode graphics initialization:<br/>
<b>This might not be a problem at all, but instead because there is no framebuffer available when using text-mode. A workaround for
the debian-installer issue below, detailed in docs/howtos/grub_boot_installer.html</b>
<a href="http://www.coreboot.org/pipermail/coreboot/2014-August/078468.html">http://www.coreboot.org/pipermail/coreboot/2014-August/078468.html</a>
look into it, follow up on that post and try to fix it.
<ul>
<li>Trisquel isolinux menu doesn't show up in seabios (seavgabios) with text-mode, it just says 'Error setting up gfxboot',
but it works in text-mode with the extract vbios. Looking at gma.c, it looks like this isn't setup in text-mode by native init,
but obviously when using the extracted vbios, it is setting everything up properly?</li>
<li>
Debian/Trisquel net-install shows graphical corruption (see mailing list link) when booting directly from GRUB in text-mode, but
works just fine when using the extracted vbios instead of seavgabios. Are these using text-mode or trying
to use graphics? <b>(graphical installers work just fine in native init or with
extracted vbios)</b>
</li>
<li>
Debian net-installer (graphical one) fails (trisquel graphical installer is ok) in native graphics and text-mode whether using
native graphics or extracted vbios (works fine in vesa/cbfb):
<ul>
<li>Scrolling/flickering text in a loop (segmentation fault):</li>

</ul>
</li>
<li>
An already-installed (on the HDD) Trisquel or Debian system boots and works just fine with native graphics + text mode.
</li>
<li>
phcoder says that there are limitations in native graphic: for example, he says native init doesn't provide int10h at all, and that it lacks VBT
(sometimes referred to as VBE).
Are there other issues? He says that there are also lots of ACPI issues in general.
</li>
<li><b>Right now it is recommended to use the vesa/cbfb ROM's (these do not use text-mode, they use coreboot's vesa framebuffer instead). MemTest86+
does work in text-mode, though.</b></li>
<li>
<b>Most (maybe all?) of the above are not a problem, I think.</b><br/>
mtjm: text mode is for payloads/OSes that use the 80x25 VGA text mode and do not change mode, or run KMS<br/>
mtjm: a more featureful VGA ROM is needed for payloads/OSes that use int10h interfaces to change modes (e.g. VESA drivers) (also, VBT and other fixes are needed)<br/>
Systems that have int10h (interrupt service) code available for reference:<br/>
Geode boards and QEMU (look in coreboot or seabios source code).
</li>
<li>
phcoder: paging will not help with mtrr granularity. This was already investigated<br/>
phcoder: interesting: coreboot exposed mistakes in fwts (firmware test suite). Like its mtrr check assumes that default=uncachable.<br/>
(might be related to those debian-installer issues in text-mode)
</li>
</ul>
</li>
<li>
About fixing remaining LCD panels on 5345:<br/>
'polarity' is mentioned in coreboot log (cbmem -c). compare output (with working and non-working panel). (and see the other notes in docs/future/index.html)<br/>
phcoder says: hint for T60: it might be that failing panels are 8bpc<br/>
fchmmr: what does 8bpc mean? And what do you think the other (non-failing) panel are?<br/>
phcoder: 6bpc. bits per colour. May also be reffered as 18-bit vs 24-bit panels<br/>
phcoder: just collect EDIDs from failing and working panels<br/>
<b>phcoder gave me this for collecting EDID data: <a href="http://www.o2genum.com/2013/08/lp156wh2-tlaa-lcd-panel-edid.html">http://www.o2genum.com/2013/08/lp156wh2-tlaa-lcd-panel-edid.html</a></b>

Apparently, only 8MB VRAM is available on i945 GPU's (though it could do 64MB):<br/>
phcoder: No. Hardware default is 8 MiB. When I wanted to make it configurable, I saw that docs mention only one other alternative: 1MiB. Later isn't event enough for 1024x768 at 24bpp without any acceleration or double buffering. It's possible there are undocumented values. Which options do you have in vendor BIOS?
How to find out how much vram you have:<br/>
phcoder: TOM - BSM<br/>
phcoder: check what vendor BIOS offers as options<br/>
fchmmr: I thought it could do 64MB usually<br/>
phcoder: not accorging to doc.<br/>
phcoder: see mobile-945-express-chipset-datasheet page 93<br/>
phcoder: see also src/northbridge/intel/i945/{early_init,northbridge,gma}.c<br/>
fchmmr: "011 = DVMT (UMA) mode, 8 MB of memory pre-allocated for<br/>
fchmmr: frame buffer."<br/>
fchmmr: "Others - reserved"<br/>
phcoder: the easiest way is a loop at this position which tries different values and reads (and prints) BSM with them<br/>
stefanct: fchmmr: he suggest that you change the value and look how BSM reacts to that<br/>
stefanct: as he pointed out earlier vram size = TOM - BSM<br/>
stefanct: different values of GMS<br/>
stefanct: phcoder: hm... this could be a hint. look at the text description of TOLUD at page 103<br/>
stefanct: it mentions 64 MB in the text about BSM as well<br/>
stefanct: table 18...<br/>
phcoder: stefanct: I have a guess which value make is 64 but I will not tell to avoid skewing test results<br/>
stefanct: phcoder: sure... i assumed you were not sure if it supports it at all. testing it properly is of course a good idea :)<br/>
stefanct: test the various possible (but reserved) values of GMS and see what the resulting VRAM size is<br/>
fchmmr: so, TOM - BSM

Other tasks (non-critical, but still important)
</h2>
<ul>
<li>
Look into those machines:
<ul>
<li>
Acer CB5 (Chromebook 5) - I'm told there is still microcode in the GPU that needs RE'd, also the wifi
is soldered and requires non-free firmware (have to disable it in nvramtool and use usb wifi dongle)
</li>
<li>
ThinkPad X200 - I'm told the Roda RK9 (same chipset as X200) doesn't come with ME, so maybe X200 can have ME removed/disabled.
Also, we don't know if it can run without microcode updates yet.
</li>
<li>
Roda rk9? (see above)
</li>
<li>
ThinkPad R400 (if X200 experiment works). I'm told it's very similar to the X200 and could easily be ported.
</li>
<li>
TODO: f2a85m and e350m1 rom's (libreboot_*_headless.rom) for headless operation. find out which PCI-E graphics cards can run without
the video bios (have to patch seabios, or patch coreboot (if using grub payload), in either case to load but not execute video bios:
then find what the driver for that card still needs, and copy/disassemble(understand) the data and write code that places that in memory)
--> maybe this could fuel a side-project (libre graphics project, for many different cards)
</li>
<li>
ASUS F2A85-M and ASrock E350M1 (desktop motherboards)
<ul>
<li>
The onboard graphics on both of these boards requires non-free video bios. Find a PCI-E graphics card that can
be used without running it's VBIOS (might still require loading data from it, which could be extracted
and studied)
</li>
<li>
<a href="future/f2a85m_dmidecode">dmidecode output for f2a85m</a> (still waiting for e350m1 dmidecode output).
</li>
</ul>
</li>
</ul>
</li>
<li>
Add 'set -e' to the start of all relevant scripts, to make them quit if an error occurs (that a command exits with non zero status).
See 'help set' for info.
</li>
<li>
Re-write deps-parabola script (again based on deps-trisquel scripts), really make it install all correct dependencies for Parabola
(on a fresh install, with only the 'base' repository installed).
<ul>
<li>Find what other scripts need fixed for this.</li>
<li>Make libreboot build in parabola</li>
</ul>
</li>
<li>
Add those to seabios:
<ul>
add ipxe (executable from seabios)
</ul>
</li>
<li>
Re-write the "Parse USB" options based on the "Search local HDD for grub.cfg" menu entry (make it more intelligent).
</li>
<li>update info on x60/t60/macbook21 pages on coreboot wiki (not really a libreboot todo, but something that I should do anyway)</li>
<li>get all useful info from http://www.coreboot.org/GRUB2 and https://wiki.parabolagnulinux.org/User:GNUtoo/laptop and make it into a tutorial</li>
<li>
Test that commit and include it (maybe get it merged in coreboot):
<a href="http://review.coreboot.org/#/c/5242/17">http://review.coreboot.org/#/c/5242/17</a> (test this!)

<a href="http://review.coreboot.org/#/c/5243/">http://review.coreboot.org/#/c/5243/</a> (test this!)
</li>
<li>
<s>Todo: (after rebase): include 6694 from review.coreboot.org (still some hanging issues). This is needed for reliable booting (for now) on macbook21</s> merged in master!<br/>
<b>work with phcoder to try and re-implement it properly (for example, ask him how to found those entries to add)</b><br/>
He says that the cst_arrays array was based on _CST object from vendor BIOS. Use acpidump and 'iasl -d' to find them.
</li>
<li>
Todo: test gnutoo's fallback patches: <a href="http://www.coreboot.org/Fallback_mechanism">http://www.coreboot.org/Fallback_mechanism</a>
(some parts use systemd. adapt for upstart, which is what trisquel uses)<br/>
see <a href="future/gnutoo_fallback_patch">this IRC log</a> (warning, not cleaned up)
</li>
<li>
are there known differences in /sys/class/power_supply between libreboot and vendor BIOS? or does the GNOME bug occur with vendor BIOS too?
(speaking about when battery is detected as "low" in Trisquel 6 / gnome when disconnecting AC/adapter)
</li>

<h2>Development notes</h2>
<ul>
<li>
Binary archive now have 2 images:
<ul>
<li>With serial output enabled and memtest86+ included (debug level 8 in coreboot)</li>
<li>With serial output disabled and memtest86+ excluded (faster boot speeds) (debugging disabled)</li>
</ul>
</li>
<li>
Reduced impact on battery life:
<ul>
<li>'processor.max_cstate=2' instead of 'idle=halt' for booting default kernel</li>
</ul>
</li>
<li>
coreboot.rom (faster boot speeds, debugging disabled):
<ul>
<li>Disabled coreboot serial output (Console-> in "make menuconfig")</li>
<li>Set coreboot debug level to 0 instead of 8 (Console-> in "make menuconfig")</li>
<li>Changed GRUB timeout to 1 second instead of 2 (in grub.cfg</li>
<li>Removed background image in GRUB.</li>
<li>Removed memtest86+ payload (since it relies on serial output)
</ul>
</li>
<li>
coreboot_serial.rom (slower boot speeds, debugging enabled):
<ul>
<li>Boot time still reduced, but only by ~2 seconds</li>
<li>has the memtest86+ payload included in the ROM</li>
<li>has serial port enabled. How this is achieved (from X60_source): Turn on debugging level to 8, and enable serial output</li>
</ul>
</li>
<li>(in Console-> in coreboot "make menuconfig")</li>
<li>(and build with grub_serial.cfg and grub_memdisk_serial.cfg)</li>

<h2>Development notes</h2>
<ul>
<li>Removed SeaBIOS (redundant)</li>
<li>
New GRUB version (2.02~beta2)
<ul>
<li>Fixes some USB issues</li>
<li>Includes ISOLINUX/SYSLINUX parser</li>
</ul>
</li>
<li>New grub.cfg</li>
<li>
Removed useless options:
<ul>
<li>options for booting sda 2/3/4</li>
<li>seabios boot option</li>
</ul>
</li>
<li>
Added new menu entries:
<ul>
<li>Parse ISOLINUX config (USB)</li>
<li>Parse ISOLINUX config (CD)</li>
<li>Added 'cat' module for use on GRUB command line.</li>
</ul>
</li>
<li>"set pager=1" is set in grub.cfg, for less-like functionality</li>
</ul>
<p>
The "Parse" options read ./isolinux/isolinux.cfg on a CD or USB,
and automatically converts it to a grub config and switches to the boot menu of that distro.
This makes booting ISO's *much* easier than before.
