Re: [Arm-netbook] Some Pine64 Experiences (via Planet Debian)

2016-10-12 Thread Matt Campbell 
Luke, I'm surprised you're interested in the Ingenic SoCs again. I 
thought you had given up on them because there aren't any current libre 
distros for the MIPS architecture. Has anything changed in that regard?


Regardless, I, for one, would strongly prefer an ARMv7 or ARM64 based 
SoC, for one reason: an ARMv7+ processor can run a huge variety of 
Android apps. While many on this list will want to run 100% libre 
software on their EOMA68 computers, I think the possibility of running 
proprietary Android apps, perhaps in a sandboxed VM on top of a libre 
OS, would increase the appeal of EOMA68 computers to a lot of people.

Calmer heads can prevail.

1. I had hoped you went in there with a seasoned translator and wise man
to defend you.

2. Remember pro microshaft engineers and executives are there as well
who could have made those silly finger pointing and escalated it.
It is in their nature.

3. In my experience of working in CN, you have a little cash, so you can
afford to be generous and get them to make some modules and kick start
business relations. No one would be interested in money talk or Linux
talk or anything else with specific headings. What they want is business
and lots of it if they rolled out the red carpet for you. So put your
business hat on, and focus around what makes orders happen. Talk about
BOM, timescales, what software you will get, and rights because you
represent the open source world, drivers, documentation, interim boards,
modules (may be pay for several modules to be built - DRAM, CPU, power
supply etc for debugging work). etc. etc. etc. If you can place a new
thoughtful order on every new meeting, you will certainly be their hero.

Your reports about the connectivity issues probably explain quite a lot. 
(Thanks a lot for posting entries from your travel diary, by the way!)

Ingenic has tried to push code into various places - SourceForge, GitHub - but 
it isn't a sustained effort, and the connectivity problem probably makes it 
even more of a chore to have to deal with such services. Best to just have 
one's own repositories and server, I think. Amusingly, the first obvious link 
I've seen to Kim Dotcom's Mega service appears on Ingenic's site. I guess that 
if you just want to get the stuff out there, that makes as much sense as 
Dropbox and all the "acceptable" sharing services. ;-)

They do have this focus on "Internet of Things", following on from 
smartwatches, and I suppose it makes sense for what they're offering. 
Similarly, those ICubeCorp people now seem to be focused on network equipment, 
if I understand the gist of their site.

I don't have much to say on whether their architecture choices make sense. I 
note that the jz4780 documentation mentions "MIPS" as opposed to just 
"XBurst", and maybe there is mileage for them in continuing along the same 
path, perhaps incorporating technologies from MIPS, perhaps evolving their own 
XBurst extensions.

Just a communication of interest could be useful, I suppose, given that 
Ingenic products aren't generally available through the obvious western 
channels (as far as I can tell) and thus no other convenient mechanism for 
communicating ongoing demand seems to exist.

Paul

P.S. On the subject of openness in general, for any small operation it does 
make sense to limit support to people who are genuine customers. One might 
argue that as long as they have customers who approach them directly and 
business is conducted on that basis thereafter, there is no need to cultivate 
a general audience for their products.

But at some point the lack of public documentation undermines general 
confidence and interest in the products being offered by any such company. 
Random engineers are less and less interested in having to enter (or having 
their managers or superiors enter) some kind of sales relationship to get 
access to materials, when it all could end in important materials being 
withheld once the supplier has gained what it wants from the relationship. 
(Think about how a lot of recruiters operate if you want another example!)

It's tempting to frame such differences in working as "east versus west" 
cultural differences, but they are not: "enter a relationship with us to get 
things done" is precisely the kind of thing that still permeates western 
academia, not helped by the rampant "intellectual property" opportunism 
infecting academic institutions. It may be the case that working together will 
bring about more rapid progress, but when one first has to evaluate who to 
work with, and when the basis of that evaluation is a limited amount of public 
information, a lot of time is wasted before any actual work can be done.

I bet you wished you met them on neutral ground. Someone there is got very

Like Frank Herbert wrote "Show me a completely smooth operation and I'll

right.  ingenic are an extremely small team: they simply haven't got
time to mess about with "support" issues for people who aren't
directly paying them.  the amazing thing is that ingenic fully
recognise this and just dump the entire source (albeit of really quite

i really really like ingenic, it's just that they've gone too

actually it's a reflection on *themselves*.  they're saying - not to
me - but to *themselves*, "if *we* were this person, *we* would
steal".  they're afraid of this "foreigner" who knows that they've
stolen GPL source code for years, and they expect me to enact out
RETRIBUTION by doing exactly what they've done, namely... to steal
from them in REVENGE.

they have no inkling that the consequences for me would be far beyond
anything that i could possibly gain from by such irresponsible action
(including legal ramifications, in PARTICULAR that i'm in china: i
would end up in jail potentially for 20 years to life if i did
anything so fucking stupid as to steal from them... that's not so much
the problem as it is that i wouldn't be able to complete the goals
that i've set, from inside a chinese jail), not to mention that it
would entirely defeat the educational objective lesson that is is
*they* who need to be the ones to take action (namely, to comply with
copyright law and alter their internal procedures right across the
entire company to match).  if someone (whoever it is) comes in and
simply *takes* the source code, that COMPLETELY defeats the object of
the exercise.

there's a book called "Invisible Dynamics" which describes the six
systemic laws that businesses *must* respect, or pay the consequences
for not doing so.  one of those systemic laws is to recognise and
respect the contribution of all employees (and by extension
contributors).  allwinner, by taking the linux and u-boot source code
and not respecting the software license, is breaking that fundamental
systemic law.

now, they don't *understand* that, which is why they're getting into
difficulties... but they can feel that there is something wrong,
without being fully aware (as individuals and as a company) of exactly
what.  they can see the public fuss but we're failing to get it across
to them, we're being angry, rude and generally giving the impression
that we're a bunch of fucking gwailo foreigner dickheads that they can

well, it's about to get a hell of a lot worse.  i flew 20,000 miles
round the world, was invited here to speak with their engineers, help
them out, set up a FusionForge for them, make it possible for them to
present the R-Series processors to open hardware and software libre

Not arguing with you there. Given his apparent involvement with NetSurf, I 
start to wonder whether he was in the RISC OS scene at some point - the name 
is familiar, certainly - but perhaps I shouldn't say such unkind things in 
public. ;-)

For the record, I'm quoting Vincent here, so the "random guy" is actually 
someone else. Going to the forums to find out who he means is one of those 
infuriating experiences involving some phpBB clone, lots of forums and 
"subforums", zillions of multipage threads, and presumably lots of people 
"hanging out" on "the boards" while useful information drains away through the 
cracks. However, it appears that Simon Eisenmann is the "random guy", in fact.

With regard to the vendor, I was referring to the Pine people, and I think 
Luke had a rant about them in the context of ordering products from Allwinner 
and not using that as leverage. After all, the Pine people are on the hook for 
any copyright infringement at the point of delivering products as part of 
their campaign.

DTRT is "do the right thing", I guess: nothing to do with device tree. ;-)

I guess this is something that more established companies figured out a while 
ago. I hope that they see that getting out of their own way actually creates 
opportunities.

Meanwhile, significant international partners should be doing their part, too: 
I noticed that Imagination had managed to prise the jz4780 SoC programming 
manual out of Ingenic for public dissemination around their Creator CI20 
product, albeit without any documentation for Imagination's own technologies 
embedded in that product. Not everyone finds reverse-engineering new stuff a 
rewarding use of their time, especially when there's plenty of other new stuff 
out there.

Vincent Sanders (kylikki) is a fairly high-level 'some random guy'.
He's part of the 'Debian digerati' in Cambridge and a _very_ long-time arm
kernel developer, so he does at least have plenty of clue.

Doesn't mean he'll keep looking after this board with new images, of
course. Which is perhaps what you meant by 'random... OS images'.

I don't really know about the pine people specifically, but having
recently met with a guy from Allwinner (who is paying Luke to educate
his engineers :-) Allwinner are definitely trying to improve things so
that we hackers get a proper experience (either docs or code with a
suitable licence), at least for some 'annointed-for-use-by-developers'
chips to start with (which is still missing the point rather, but them
concentrating efforts on selected products to start with probably
makes practical sense, and maybe one day it'll apply to everything, as
it should). One fight at a time...

They have noticed the persistent bad press/poor reputation and have
understood that what geeks think does actually matter in the long
term, as does upstreaming. It's a big company of course and not
everyone gets it yet, but I think we'll see progress over the next few
months, and hopefully be in a rather better place this time next year.

If we can get Allwinner to DTRT then a) it's much easier for board
manufacturers to DTRT and b) we care less because we can fix things
ourselves and mainline stuff can be used.
