Hi,
I'll do some maintenance on our code review site tomorrow morning
(CEST). There's not really a schedule, but it will be quicker than
last time.
I plan to integrate an authentication module to support Google
accounts for authentication beyond April 20th when Google retires the
protocol we currently use. I will report to the mailing list when I'm
done.
Note: The change will require some work by affected users (1 minute
per account) to migrate the authentication information and retain
access. I'll post instructions when the system is ready.
Regards,
Patrick

What if A8 model is supported as well, just not tested yet? These APUs are
very similar to each other, after all ;)
Maybe a knowledgeable coreboot developers, especially those who have ported
coreboot to G505S, could tell what parts of code are A10-specific - and, if
there is indeed such a code, how to change the parameters of that code to
make them suitable for A8 ?
In case they don't reply: if you have SPI clip as well as BIOS programmer
that supports many chips including MX25L1606E , could try a following
scenario:
1) get A8 G505S locally & try to install coreboot
2) if it works, announce it to a mailing list that there's a support and
keep a laptop to yourself ; but if it doesn't work - even after playing
with parameters - and a laptop is bricked, you could restore a
manufacturer's BIOS using SPI clip & BIOS programmer, and then return a
laptop to seller...
About A10 model - it does not seem to be US-only: there are a lot of offers
in Russia, as well as at "developing countries" such as Thailand/India
(maybe that stock was inherited from EU countries) But, because of huge
quantity of different laptop models/modifications, and dependence of their
local availability on local retailers' preference, there are countries
which got either a small stock of G505S or none at all! :P And that returns
us to "reasonable availability" debate... In my perception:
"Reasonable availability" for a laptop model, is when a person is able to
get a new laptop (not used/refurbished) - for a price that does not exceed
the manufacturer's list price by more than X % of it. (e.g. 25%). That
additional condition regarding the list price is necessary, because if
there would be some greedy retailers left - who didn't sold out their large
stock just because of outrageous unreasonable prices - I wouldn't call this
as "reasonably available" ;)
As you see, "reasonable availability" is a quite subjective term, because
if your country doesn't have a stock of this laptop:
*) your price would be not just price of unit but also a shipping price
from other country, + possible import taxes
*) there are various risks: if, because of your location, you cannot buy a
laptop in store after checking its quality,
a laptop could have manufacturing defects that are not enough to request a
replacement/partial refund, e.g. laws based on ISO 13406-2 standard could
allow a seller to refuse a replacement of laptop if there are a few
annoying dead pixels.
These risks have a different "weight" in the eyes of different people, e.g.
many people wouldn't consider it as "reasonably available" even if it's
available from neighbor country with a low shipping price, because they do
not want to risk. And that makes this term even more subjective and hard to
measure by automatic metrics...
P.S. Indeed, some laptops that are listed in coreboot "LTS Candidates" list
( http://www.coreboot.org/User_talk:MrNuke/LTS_Candidates ) have A10-5750M
as well and seem to be more "reasonably available" than G505S, at least for
your country. But, despite having a somewhat similar hardware, nobody
ported a coreboot to them yet :P
Best regards,

Could that approach please be discussed with all firmware, payload and
firmware projects? For example, coreboot (and the depthcharge payload
used on Chromebooks and Chromeboxes) already store the time stamps in
its CBMEM, which can be read with the utility `cbmem` with `cbmem -t`
[1] or with GRUB’s `coreboot_boottime` command.
10 entries total:
10:start of ramstage 9
30:device enumeration 441 (432)
40:device configuration 95,357 (94,915)
50:device enable 99,275 (3,918)
60:device initialization 109,246 (9,971)
70:device setup done 181,906 (72,659)
75:cbmem post 182,274 (368)
80:write tables 182,276 (2)
90:load payload 183,873 (1,597)
99:selfboot jump 283,779 (99,905)
GRUB also has a `boottime` command outputting times like how long a
module needed to load.
One approach would be, that the Linux kernel has drivers to read the
different implementations on how to store the boot time and then exports
those to userspace.
The other approach, and probably more feasible one, is that all firmware
projects use the same standard/specification.
What is actually needed? Are pairs of
project, stage name, time in milliseconds since start of program
where each project gets assigned a unique ID. Do you need more data?
Thanks,
Paul

Hi
I am running coreboot on qemu with the following sequence.
coreboot -> seabios -> GRUB -> kernel.
The kernel booting hangs at *All ACPI Tables successfully acquired*
coreboot-4.0
kernel 3.19
when I pass acpi=off to the kernel command line parameter the kernel boots
fine in this scenario.
Is there any specific coreboot option thats need to be enabled for
successful booting.
or anyone knows of this isuue
Thanks
Ajoy

My point is not to limit your LTS list to US laptops. US has
*extraordinary* availability for a lot of gear.
There's also the matter of procurement and warranty. A company won't bother
importing some laptop from outside the EU just because a developer wants it
-- they will look locally and as a last resort within the EU.
Except some brands (Apple comes to mind) warranty becomes a hassle if the
laptop breaks. Transport costs, long wait time and language issues
complicate matters.
Amazon Germany seems to have 2 laptops in stock with A10. Amazon
Spain/France/Italy/Netherlands has none. Only Amazon UK seems to have it
without giving a stock warning (but it's sold by a 3d party).
Anyhow, I don't want to sidetrack this, but the first criteria for the LTS
laptop is "reasonable availability"...
Perhaps you should have some metric for availability (this could even be
automated somewhat). Pick a list of top electronics sites/stores from a
list of countries and define a formula based on model availability.
Alternatively, it would be great to support the A8 too!
To me the the G505S would clearly be a better machine to recommend compared
to an ancient Thinkpad X2xx!

If I am not mistaken, your country is Romania... Unfortunately - if I
didn't skip something - it looks like Romania went out of A10 stock just a
couple of weeks ago! However, I found many offers from Hungary, which is
very close! Some offers are listed on "price list"-type websites (e.g.
http://www.arukereso.hu/CategorySearch.php?st=g505s+a10 ) while others are
not listed anywhere (e.g.
http://www.notebookspecialista.hu/lenovo_ideapad_g505s_59_422983_notebook-1…
)
Nice thing is that these offers usually have A10 + R5 230M, slightly faster
dual graphics. But the majority of G505S models selling in Europe have Win8
pre-installed, so I'm afraid it would be hard to avoid paying extra for
this bloatware, in your case :P
As for other European countries, it is difficult for me to look through the
entire EU because there are many countries with many languages. I only know
English as foreign language, and thats why the majority of foreign offers
I'm able to find, are in UK/US...

Well, the G505S with A10-5750M is explicitly listed as no longer being
sold. So it's the A8 or nothing.
Could you provide links within the EU with (online) shops still selling the
A10 variant and having some actual stock?

To my knowledge, Nuvoton will send you the datasheet for your Super I/O
chip if you contact them. Please try that first.
> Can I get basic functionality without the Super-IO?
It depends. Normally, a similar chip is taken which is often compatible
for at least serial console output.
> Can I reverse-engineer support for it?
Sure you can. But that is probably quiet hard compared to requesting the
datasheet. You can analyze the vendor firmware and find out how the
Super I/O is initialized.
Another way is to look if the support for your Super I/O exists in the
Linux kernel sources (lmsensors) to find out more about it.
Good luck with implementing support for your device!
Thanks,
Paul

Hello! This is my first time doing anything with coreboot, so please
forgive my newbie mistakes.
I am working to add support for my motherboard (Asus Q87T) to coreboot.
Here are the basic specs:
-Haswell CPU (Supported)
-Intel Q87 (C220) PCH (Supported)
-NUVOTON NCT5538D Super-IO (NOT Supported)
I had to send the board back for a warranty replacement (not coreboot
related), so I have not done any dumps from software. I was not able to get
access to a datasheet for the Super-IO.
How should I proceed? Does anyone have any information about this chip (or
a similar one)? Can I get basic functionality without the Super-IO? Can I
reverse-engineer support for it?
Thanks for the help!
Yes, in addition to A10-5750M based G505S there are also A8 and A6 ones.
But there are some possible problems regarding them:
1) their price is just slightly lower than with A10 - as result,
price/performance ratio seems to be worse for these models
2) I'm not sure if it is possible could upgrade their APU from A6/A8 to
A10-5750M after purchase
3) most importantly: some parameters inside a coreboot source code for
G505S could be A10-specific ;
I am not sure if a current "A10-inclined build" would run on A8/A6 out of
the box, without additional tweaking
A question from my last letter - about compatibility of G505S coreboot
build with various graphics solutions found in different modifications, is
not addressed yet... to remind, there are three groups of modifications:
*) only 8650G (no dual graphics)
*) 8650G + AMD HD 8570M (dual graphics)
*) 8650G + AMD R5 M230 (dual graphics, slightly faster)
P.S. Below is an =incomplete= list of SKUs for A10 G505S models that I was
able to find. If there is a shortage in your country, maybe this list could
assist you in search (those mods with windows 8 are about $50 more
expensive and support evil M$, please dont get them ;-) )
1) only 8650G (no dual graphics) + 4GB + FreeDOS = 59-410323
2) only 8650G (no dual graphics) + 8GB + FreeDOS = 59-405169
3) only 8650G (no dual graphics) + 4GB + Windows 8 = 59-380131
4) only 8650G (no dual graphics) + 6GB + Windows 8 = 59-373010 / 59-406417
5) only 8650G (no dual graphics) + 8GB + Windows 8 = 59-403088
6) 8650G + AMD HD 8570M (dual graphics) + 4GB + FreeDOS = 59-405168
7) 8650G + AMD HD 8570M (dual graphics) + 6GB + FreeDOS = 59-409773
