<div dir="ltr"><div>What if A8 model is supported as well, just not tested yet? These APUs are very similar to each other, after all ;)<br></div><div>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 ?<br></div><div><br>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:<br></div><div>1) get A8 G505S locally & try to install coreboot</div><div>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...<br></div><div><br>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:<br><br></div><div>"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" ;)<br><br></div><div>As you see, "reasonable availability" is a quite subjective term, because if your country doesn't have a stock of this laptop:<br>*) your price would be not just price of unit but also a shipping price from other country, + possible import taxes<br>*) there are various risks: if, because of your location, you cannot buy a laptop in store after checking its quality,<br>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.<br>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...<br></div><div><br></div><div>P.S. Indeed, some laptops that are listed in coreboot "LTS Candidates" list ( <a href="http://www.coreboot.org/User_talk:MrNuke/LTS_Candidates">http://www.coreboot.org/User_talk:MrNuke/LTS_Candidates</a> ) 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<br><br></div><div>Best regards,<br></div><div>Vladimir Shipovalov<br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 7 April 2015 at 16:17, Emilian Bold <span dir="ltr"><<a href="mailto:emilian.bold@gmail.com" target="_blank">emilian.bold@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">My point is not to limit your LTS list to US laptops.

I believe it is an excellent idea, because:<br><br><b>1)</b> Lenovo G505S contains AMD APU, so there is no need to deal with Intel ME/AMT so-called "features"<br><b>2)</b>
this APU has Richland architecture: as result (unlike the more recent
AMD offerings) it doesn't have "AMD Secure" feature -- based on ARM
Trustzone technology which already has some exploits against it; there
are security concerns about ARM Trustzone that are similar to concerns
about Intel vPro "feature" (remote management etc.)<br><b>3)</b>
this APU is A10-5750M, the most powerful mobile APU among Richland
designs - as result, this laptop is still very competitive regarding its
performance, and also price/performance<br><b>4)</b> Unlike the
older HP M6-1035DX amd laptop, Lenovo G505S seems to be a very popular
model: even now, more than 1.5 years after its' introduction, there are
>200 Internet shops in my large city still selling it new in box -
not used/refurbished<br><b>5)</b> Lenovo G505s works
without microcode updates, and already has a working Coreboot build
(although Video BIOS and SMU firmware have blobs that are still not
reverse-engineered; and some minor issues - e.g. ACPI not perfect yet )<br><br>These great points are making me wonder, why this interesting laptop
still haven't been added to that LTS Candidates list? Does it fail to
meet some requirement for LTS candidates in a not-obvious way
(RYF-certifiable,Sturdy,Long shelf-life,Cool factor) or there is some
not-listed AMD laptop that could be a better candidate?<br><br>By the way, I have discovered that there are many modifications of
Lenovo G505S, which could be divided into three primary groups by their
major difference - GPU <i>(minor differences, such as different size of RAM or hard drive, are not interesting)</i><br></div><div>GPU modification groups:<br></div><div><div><b>1)</b> only 8650G, which is built-in into APU (no dual graphics)<br></div><div><b>2)</b> 8650G + AMD HD 8570M (dual graphics)<br></div><div><b>3)</b> 8650G + AMD R5 M230 ( dual graphics, slightly more powerful than "2)" )<br></div><div>Are these modifications all supported by Coreboot? And would be there any additional difficulties regarding modifications with dual graphics?<br></div><br></div><div>Your answers and opinions will be very welcome<br>Best regards,<br></div><div>Vladimir Shipovalov<br></div></div>
