Re: [fedora-arm] ARM summit at Plumbers 2011

[Luke Kenneth Casson Leighton]

russell, good to hear from you.

can i recommend, that although this is a really wide set of
cross-posting on a discussion that underpins pretty much everything
(except gnu/hurd and minix) because it's linux kernel, that, just as
steve kindly advised, we keep this to e.g.
cross-distro@lists.linaro.org?  i'll be doing that from now on [after
this] perhaps including arm-netbooks as well, but will be taking off
all the distros.

so - folks, let's be clear: please move this discussion to
cross-distro@lists.linaro.org, and, if it's worthwhile discussing in
person, please do contact steve, so he can keep the slot open at the
Plumbers 2011 summit.

 i think... russell... after they are told, repeatedly, "no, you can't
have that pile of junk in the mainline linux kernel, Get With The
Programme", you'd think that, cumulatively if they end up having to
maintain a 6mb patch full of such shit, they _might_ get with the
programme?

 and if they don't, well.... who honestly cares?  if they don't, it's
not *your* problem, is it?  _they_ pay their employees to continue to
main a pile of junk, instead of spongeing off of _your_ time (and
linus's, and everyone else's in the Free Software Community).

 then don't f******g make it _your_ problem, or anyone else's, upstream!! :)

 this is the core of the proposal that i have been advocating: if it's
"selfish", i.e. as bill and many many others clearly agree with "if
the bang-per-buck ratio is on the low side" then keep it *out* the
mainline linux kernel...

 ... and that really is the end of the matter.

the sensible people that i've been talking to about this are truly
puzzled as to why the principles of "cooperation and collaboration"
behind free software are just being... completely ignored, in
something as vital as The Linux Kernel, and they feel that it's really
blindingly obvious that the "bang-per-buck" ratio of patches to
mainline linux kernel need to go up.

 so the core of the proposal that is the proposed
"selfish-vs-cooperation patch policy" is quite simple: if the patch
has _some_ evidence of collaboration, cooperation, refactoring,
sharing - *anything* that increases the bang-per-buck ratio with
respect to the core fundamental principles of Free Software - it goes
to the next phase [which is technical evaluation etc. etc.].
otherwise, it's absolutely out, regardless of its technical
correctness, and that's the end of it.

 the linux kernel mainline source tree should *not* be a
dumping-ground for a bunch of selfish self-centred pathological
profit-mongering corporations whose employees end up apologising in
sheer embarrassment as they submit time-pressured absolutely shit
non-cooperative and impossible-to-maintain code.

 you're not the only one, russell, who is pissed off at having to tidy
up SoC vendors' patches.  there's another ARM-Linux guy, forget his
name, specialises in samsung: two years ago he said that he was
getting fed up with receiving yet another pile of rushed junk... and
that's *just* him, specialising in samsung ARM SoCs!

we're just stunned that you, the recipient of _multiple_ SoC vendors
piles of shite, have tolerated this for so long!

anyway - i've endeavoured to put together some examples, in case
that's not clear: i admit it's quite hard to create clear examples,
and would greatly appreciate help doing so.  i've had some very much
appreciated help from one of the openwrt developers (thanks!)
clarifying by creating another example that's similar to one which
wasn't clear.

   http://lkcl.net/linux/linux-selfish.vs.cooperation.html

this should be _fun_, guys.  it shouldn't be a chore.  if you're not
enjoying it, and not being paid, tell the people who are clearly
taking the piss to f*** off!

 but - i also would like to underscore this with another idea: "lead
by example" (which is why i've kept the large cross-distro list)  we -
the free software community - are seeing tons of nice lovely android
tablets, tons of nice lovely expensive bits of big iron and/or x86
laptops, and only in very small areas (OpenRD Ultimate, GuruPlug,
Pandaboard, IMX53QSB, Origen) are our needs for actual hardware which
_we_ want (and i'm *not* being presumptious here - i'm inviting people
to *say* what they want) just aren't being met.

 who wants a bloody 800x600 VIA VunnnderMedia ARM9 350mhz tablet, to
do linux kernel and gnu/linux distribution development on, _anyway_???
  and who the hell wants only 512mb of RAM (iMX51).  and who in their
right fucking mind dreamed up that 1024x600 LCD panel size?

 so here's what i propose:

 we, The Free Software Community, want Our Figureheads (linus, bruce,
alan, russell) to call us to arms (so to speak), to band together a la
KickStarter http://kickstarter.org (or other), so that we can create
the hardware platform(s) that *we* want, and, in the process, can take
the opportunity to sort out the Linux Kernel mainline tree in the
process (learning by doing, doing by leading, leading by example etc.
etc.)

 apart from anything - and this goes to you, linus and russell - i
think that you would be much happier taking a break from doing git
patch conflict management, _actually_ getting down and dirty with some
real device driver writing, and i think you'd be much happier doing
that knowing that the device you were writing those kernel drivers for
was something that actual real free software developers really really
wanted.

 now, as i said above: i don't _dare_ to presume that i know what
actual real free software developers want, in terms of hardware, but
there's a small sampling on the debian-arm mailing list... let me drop
you roughly in the middle of it, here:
http://lists.debian.org/debian-arm/2011/08/msg00045.html  mostly that
was focussed around those little engineering boards (panda, IMX53QSB,
origen etc.) but my aim here is to get people to think:

 what hardware, which is fully free-software-compliant, that you would
buy and recommend to others, that could also be attractive in
mass-volume, do _you_ want to see, that would be useful to _you_?

 i'm getting fed up of seeing stuff come out of factories that's
completely useless.  or gpl-violating.  and/or requires
reverse-engineering.
http://lkcl.net/linux/ideal-vs-reality.of.product.development.html for
some background.

 as a free software developer, what hardware do YOU want?

 answers on this one to arm-netbooks@lists.phcomp.co.uk (subscription
required, please remember)

 and, lastly - linus, russell, alan, bruce: there are people out there
who would really appreciate if you could take up this call.  not just
me.  we'd like to see you using your skills, and actually be happy and
enjoy doing nitty-gritty linux kernel development, to the benefit of
the free software community, instead of turning into patch
junkies^H^H^H^H^H^Hmonkeys^H^H^H^H^H^H^Hmanagers.

 keld, the encouragement is appreciated, and i do follow the reasoning
(which is that, given that gnu/linux distros are at such an
interesting threshold point, there's simply been no need for such a
large cross-posting before).

 but, i have to keep my word, and i said i wouldn't interrupt people
on such a large scale, preferring instead that those people who are
*actively* interested participate.  if, however, *you* - or anybody
else feels that this topic still needs to reach a wider audience, in
order to help things reach critical mass, please do actively bring it
to their attention.

 i have another write-up, done today, which brings together both the
software and this time hardware strategic design concepts that i
believe will help put control firmly back into the hands of Free
Software Developers:

 http://lkcl.net/linux/modular.computing.architecture.html

 linus: if you're happiest doing device driver development, then for
goodness sake stop complaining about how bad ARM development is going,
and get involved in a real-world ARM embedded project.  not just _any_
old ARM embedded project, but a "Meta-"Project that would help future
Linux Kernel Development through large-scale code re-use.  and,
through that, you'd actually really _really_ begin to appreciate why
Russell's getting so pissed off.

 russell: i realise that this is going to sound strange, but if you're
actually _happy_ continuing to get pissed off and disillusioned with
being nothing more than a Git Patch Conflict Manager, please feel free
to completely ignore the entirety of this message _and_ the link
above.  you _can_ tell people to piss off: you're perfectly within
your rights as a Free Software Developer to do so.  take a busman's
holiday: lead by example and help spearhead this project.

everyone else: if you feel that you want to see happen a project to
put the kind of hardware that is desirable *to you* into *your* hands
(because it was, like the OpenPandora, developed with open involvement
from its community, rather than developed in secret and presented as a
fait-accomplit), then make yourself known - especially to those people
whom *you* believe should spearhead the project.

also it has to be said that if you believe that there is someone else
whom you feel would be more suitable to spearhead the project, please
do say so - and help campaign to bring them in.

OpenPandora was - is - a *success*, despite vast sums of money - 4,000
preorderers *up-front* money held in escrow - being spent on casework
and on making mistakes such as paying an ex-TI employee $50k to fail
to get the 1251 WIFI module PCB area right.

learning from these mistakes, it *is* possible to drastically cut the
cost of hardware development, by leveraging existing designs and
adapting them.

now, it has to be said that if, after hitting such a large audience i
_still_ don't get any traction on this project, then that's it, i'm
"dun spammin".  as an experienced Free Software Developer with
ARM-embedded HTC Reverse-Engineering experience, i _will_ continue as
best i can to play "guess what kind of hardware that Free Software
Developers would want", and i _will_ continue to fit this into ongoing
negotiations with PCB Factories in China, with whom i have been
working hard to get them to respect and understand the importance of
GPL Compliance *up-front*.

a translation of that paragraph is: you, The Free Software Community,
are being presented with an OpenPandora-like opportunity, to leverage
negotiations for the production of mass-volume products, to actually
really REALLY get that decent ARM Laptop with a pre-loaded GNU/Linux
Distro of YOUR choice (*), or that decent Desktop PC with a pre-loaded
GNU/Linux Distro of your choice - whatever it is, you need to speak up
NOW.

and the reason you need to speak up right now is because then i can
justify going to the factory to say "yes, there are NN people who want
this", and it goes from there.

but, of course, it goes without saying, that if you would prefer that
there be other figureheads leading this project, for them to choose
appropriate factories and to negotiate them into GPL compliance,
please feel free to do so, and take this opportunity to speak up and
to campaign for such figureheads to back this project.

i don't mind that happening: all i want is my damn 1280x800 12in (and
importantly $160) ARM-based laptop, damnit :)

l.

(*) instead of a laptop with only 512mb of RAM.  or a 1024x600 LCD
(Toshiba AC100, Genesi Efika, AlwaysInnovating, etc.).  or being
vapourware (too numerous and pointless to enumerate).  or being an R&D
model which was so expensive to develop that no retailer could touch
it (e.g. the Pegatron Netbook).  or being effectively closed-source
(almost every Android product in existence).  or GPL-violating (almost
every Android Tablet in existence).  or requiring reverse-engineering
(the Toshiba AC100).

 ok, so: follow-up:

 is anyone interested to know what the costs would be, of an
engineering board conforming to the above strategy, using a low-end
Cortex A9 CPU such as the AML-8726-M? (for reference, the 8726 is
known to be between $13 to $15 depending on volume)

 does anyone have any questions, comments or suggestions regarding the
strategy to place cooperation and collaboration back at the heart of
linux kernel development?

 any ideas on how to improve the software development tools (such as
git) to help make that strategy easy to be part of the day-to-day
development process?

 perhaps most importantly, does anyone have any _better_ ideas than
what's being proposed?

 or, is everyone happy with the way that things are, and thinks that
they should continue as-is (perhaps until russell quits completely, or
linus bans ARM patches entirely from the mainline linux kernel)

 what is it going to take for people to engage on these issues?

 does anyone want to take responsibility for making sure that there is
some progress?
