I'm hoping for a slot on Thursday evening, but this remains to be confirmed at this point. We had some lively discussion about the state of ARM Linux distros at the Linaro Connect [2] event in Cambridge last week. It rapidly became clear that some of the topics we discussed deserve a wider audience, so we're suggesting a meetup at Plumbers for that bigger discussion. The initial proposed agenda is: * ARM hard-float + What is it and why does it matter? + How can distributions keep compatible (i.e. gcc triplet to describe the port)? * Adding support for ARM as an architecture to the Linux Standard Base (LSB) + Does it matter? + What's needed? * FHS - multi-arch coming soon, how do we proceed? * 3D support on ARM platforms + Open GL vs. GLES - which is appropriate? but I'm sure that other people will think of more issues they'd like to discuss. :-) If you wish to attend, please reply to the cross-distro list and let us know to expect you. Make sure you're registered to attend Plumbers Conf, and get your travel and accommodation organised ASAP.

Unfortunately there is no way I could make it, but on the subject of 3D support on ARM, Luke recently mentioned something that initially seemed outlandish but upon closer examination doesn't seem like a bad idea. As we all know, the state of openness of specifications of commonly used ARM 3D GPUs is at best dire. What has been proposed is a bit radical, but it doesn't actually seem that implausible. Specifically, combining Open Graphics Project (http://wiki.opengraphics.org/tiki-index.php) and the xilinx zynq-7000 or similar (dual core Cortex A9 + FPGA). The idea is to have an OGP GPU in firmware in FPGA. In terms of the power budget, it seems to work relatively sanely considering what it is, and it is as ideal as it gets as far as openness and flexibility goes. I just thought it's worthy of a mention. Gordan ^ permalink raw reply [flat|nested] 11+ messages in thread

It does seem outlandish, but it is kind of cool. Is it going to give enough 3d speed? The next gen tegra is supposed to have a 24 core GPU. It is probably more sane then my idea of just having a test suite from digital video out -> digital video receiver/capture card to get known test results. Then you could set up a hinted genetic algorithm based on a comparison. It would only work with digital video signals though. ^ permalink raw reply [flat|nested] 11+ messages in thread

There really aren't many applications around at the moment to make this an issue. I'd be more interested in it's ability to decode 1080p. Then again - it's FPGA! You can load a different "firmware" depending on whether you need 1080p decoding or 3D rendering, or some other kind of specialized DSP offload with only bare minimal VGA. :) Personally, I think OGP would be worth it even if just for the fact that we would no longer have to beg (in vain) the vendors for decent drivers or published specs. The added flexibility on top is just a "free extra". :) Gordan ^ permalink raw reply [flat|nested] 11+ messages in thread

It rapidly became >clear that some of the topics we discussed deserve a wider audience, >so we're suggesting a meetup at Plumbers for that bigger >discussion. ok. allow me to give some perspective and background as to why i believe that a bigger discussion is important, and to whom that discussion is important. a few years ago i read what seems like a silly book, called "The Strategy-Focussed Organisation". sounds trite, but i was advised to read it when i proposed some ideas and was confronted with the very valid question "why should i [a lowly "developer"] _care_ about this 'strategy' that you are proposing?" (fortunately the person who asked the question was the same one who advised me to read this "silly" book). it's a tough one, isn't it? why should any of us - as free software developers - _care_ about the state of ARM Linux? you're getting on with the truly crucial task of managing the distro that you're committed to. it's a focussed job: it's a vital role, and you should not let anyone tell you otherwise. yet... and this is the bit that this silly book explained: it's just as important to know where *your* role "fits in" with what else is going on. linaro, for example, as you no doubt well know, is tasked (by its subscribers who pay $1m / year) with sorting out vital underlying infrastructure that ties what *you* are doing in with the subscriber's ARM CPUs. you're doing the user-facing stuff; they're doing the CPU-facing stuff. that's *their* strategic role: in concrete terms it means sorting out gcc with ARM optimisations, and it means seeking out and/or increasing the number of areas of shared and refactored code across as many places as possible, in order to reduce the software development effort required of their subscribers. linux kernel. device tree. LSB. (and, it has to be said, _if_ the stupid, stupid 3D GPU companies got with the picture, linaro could well take gallium3d for example under its wing, too). so the key question is: if linaro is "taking care of" this aspect, because that's linaro's role, then why _should_ any distro maintainer care? yes they should be aware of what's happening, but there's no real incentive to get pro-actively involved, is there? all that's required is passive acceptance of the work filtering down from linaro... and this perhaps explains the lack of response to the proposed meetup, steve. [the other reason is that yes, although _discussion_ can take place about 3D GPUs, we as free software developers feel "powerless to act" in the face of so much money. despite the fact (which personally makes me extremely angry) that without our overall contribution these companies simply would not have a gnu/linux distro or a linux kernel on which to make that money]. so, the important question to ask, then, is what *is* good motivation to take action? if, indeed, any action need be taken at all, which is a perfectly reasonable conclusion to reach. not that i personally agree with that, but i can live with it :) and, to answer that question, i feel it's important to take into account some context and background. many of these things you will already be aware of, but let me put them all together, here. take a deep breath... * with the rise of android, Matt Codon shows us an empirical glimpse into the blatant state of GPL violations by OEMs taking place on the Linux Kernel and more: http://www.codon.org.uk/~mjg59/android_tablets/ * many android vendors have lost the right to use linux kernel source code. this article is the most insightful and non-aggrandising i've yet found into the GPL violations situation and its consequences: http://fosspatents.blogspot.com/2011/08/most-android-vendors-lost-their-linux.html * Our Linus declared in april that he was getting fed up with the state of the ARM Linux Kernel. my take on this is that there is an overwhelming amount of "selfishness" creeping into the Linux Kernel development. Our Linus has also recently stated that his passion is actually low-level device driver development. http://thread.gmane.org/gmane.linux.kernel/1114495/focus=112007 * Russell King, the ARM maintainer, has completely lost all motivation to work on the task of merging ARM Linux patches. with the amount of selfishness that has been going on for so many years, i am surprised he's tolerated it this long. http://article.gmane.org/gmane.linux.kernel/1121096 * I've seen proposed solutions and many many descriptions of the problems caused by the rise of ARM Linux, but none of them look at this from an "overview" perspective, which is that the core of the problem is lack of cooperation and collaboration - precisely counter to the whole purpose of Free Software. here, i hope and believe, is a small insight into that, along with some references and links: http://lkcl.net/linux/linux-selfish.vs.cooperation.html * an attempt last year to motivate people to get together to buy an early ARM Laptop (the CT-PC89E) which would have been available at the time in mass-volume for $102, the design of which turned out to be sponsored by China Telecom, found more than just GPL violations on the Linux Kernel and u-boot source code. from this chinese factory (who were purely hardware assemblers and middle-men. girls actually) one of the ICs responsible for keyboard and mouse was "black" - no markings; the gnu/linux distribution "mid-linux.com" was *also* a GPL-violating distro which may have links to China's Great Firewalled "Red Flag" Linux; the ODM (who licensed the design from China Telecom) was instructed to offer us nothing more than China Telecom 3G CDMA modems (useless for Europe which needs UMTS); successful reverse-engineering of a linux kernel onto the device encountered evidence of "security" attempts to lock the GPL-violating kernel to the device (which we easily replaced); when my associate presented Debian GNU/Linux running on the device at a meeting with the ODM and told them it had an entirely GPL-compliant and entirely Free GNU/Linux Distro on it, which we wanted to sell across the world, they went very very quiet. lastly, Frans, who created the Debian Installer Port for the 20 people who bought the CT-PC89E samples, is dead. by suicide. i leave these as facts - stated facts - and allow YOU to sift through them and choose which ones to put together, to make your own conclusion(s). they may OR MAY NOT be related. * the FreedomBox Foundation has a clearly-stated goal, to create the software around small boxes that provide "transition" technology off of non-free and privacy-invasive servers that are all too tempting for corporations and governments to interfere with or peek at... yet there is a clear disconnect and a very wide gap between stating the goal and actually taking any action to go about creating the software, which has clearly not been addressed. The Elephant is in the room, here... * the UK government was praised by China for looking into possible censorship of the Internet: http://yro.slashdot.org/story/11/08/16/0019248/China-Praises-UK-Internet-Censorship-Plan http://news.slashdot.org/story/11/08/22/217206/Twitter-To-Meet-With-UK-Government-About-Riots * amongst many other things, the USA continues to take illegal control of DNS zones, destroying the trust and sovereignty of the very fabric of the Internet. * nokia (who received a $EUR 0.5 billion loan from the European Investment Bank just a few years ago) - our darlings who were using debian as the basis for their smartphone strategy - bought the proprietary and non-community-driven late-GPL-releasing Trolltech, and then recently pulled out of meego _and_ the open-sourcing of Series 60 and out of free software entirely with the famous "burning platform" quote from their CEO. * HP has very wisely just fire-sold their entire tablet stock in a way that will completely recoup their capital outlay (if it has a resistive touchscreen then the BOM is an estimated $80 and the tablets have sold out in a few days at $98: $18 is just enough wiggle-room for shipping as well as possibly even a modest profit, particularly on the 32gb version @ retail $150. if it's capacitive, the BOM will have an extra appx $30 on top, meaning they'll get all the working capital back... just). * lastly and perhaps most crucially, it has to be said that this "Peak Oil" thing, along with the "Global Warming" thing, is undeniably taking a grip on the world, which leaves people with a choice to *readily* face it (i.e. be prepared and better yet as well get _other people_ prepared, as a secondary priority), or to face the upcoming situation in a "Crisis" mode, which, if faced *as* a "Crisis" is quite likely to result in your death. people such as joey hess clearly get it: joey now lives entirely off-grid, and yet still has an internet connection. in a forest. i live in a remote area of scotland, now, in a place which has its own well, and we're growing our own food. it's still a work-in-progress. i could continue with this, and expand it with more examples, but let me make some summary points: * we're intelligent people, who have achieved a great deal * we're responsible for creating the software that underpins today's computer technology * governments are waltzing in and doing whatever they feel like. * corporations are creating hardware WITHOUT taking us into account, and are grabbing with both hands and returning nothing. in short: we - intelligent Free Software Developers - are having the piss taken out of us, to put it mildly. so - i tell you what: i'm going to stop there, for now. i'm going to leave it at that, for people to think, digest the above, and perhaps come up with some answers [i have some ideas, but i want to know most crucially if people are willing to hear them!]. and, to give you an opportunity to think: is this my problem, at all? do i actually care? what _is_ my role? and, if i _do_ care, what could i do if i combine with a number of other people who also care? i trust that you can see that the scope of the background goes wayyy beyond that which linaro is tasked with, so i hope - i really do - that you feel that this really is something which you care about and can actually feel motivated to consider that _some_ sort of action needs to be taken, beyond the very valuable tasks and roles which you are presently carrying out. if, on an individual basis, you feel that the answer is "no", it's not my problem, then i can only apologise for having taken up your time, and wish you good luck with the future. l. ^ permalink raw reply [flat|nested] 11+ messages in thread

And we wouldn't be discussing the various GPL and other violations that you cite were it not for the overwhelming successes of Free Software, ARM, Linux, and Android. We are well past debating the merits of Free Software et. al, which itself is a huge milestone that we need to recognize. Now it's time to let the lawyers do their jobs. And they will, because there are tremendous sums of money at play. Money that wouldn't be there if it weren't for us developers. But we need to stay out of their way, while at the same time taking care to continue producing tangible things that are worth fighting over. As developers, we've won. Deal with it. Revel in it. And then get over it. I have observed all the hand-wringing regarding the state of ARM Linux, and it's obvious to everyone that there is still work to be done. ARM isn't like PCs, and that's obviously inconvenient for Linus but it's an essential part of ARM's success. Russell King has been overworked for a decade or more, attempting through sheer force of human/developer will to keep ARM Linux from running off the rails. As far as ARM Linux is concerned, I think we're dangerously close to being smothered by our own success. We have to learn to work smarter, because we can't work any harder. And I applaud Linaro and the countless others for recognizing this problem and looking for ways to resolve it. I for one would love to participate in the ARM Summit, but I'm a sole proprietor without an expense account to charge the travel costs to and they are too large for me to carry personally. I suspect I'm not the only one in that situation. The fact that there has been little response to the ARM Summit doesn't mean that nobody cares or that the problems seem to large to solve. It just means that we're going to have to find a different way to get this work done. b.g. -- Bill Gatliff bgat@billgatliff.com ^ permalink raw reply [flat|nested] 11+ messages in thread

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). > I doubt that hardware people > coming up with these abominations even care one bit about what's in > the kernel. 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. l. ^ permalink raw reply [flat|nested] 11+ messages in thread

I'm obviously confirming, but I'll repeat that for the record. My interests here include helping to lead up Fedora's ARMv7 efforts, but also wider ARM platform standardization (boot, device enumeration, multi-arch, ABI, kernel consolidation, and many other things). If there's at least representation from a few of the distros (as it seems is the case at this point) then I think it's worthwhile having the formal slots. Nothing is lost in so doing. In any case, many discussions will take place if we have the opportunity to do so. Jon. ^ permalink raw reply [flat|nested] 11+ messages in thread

I've certain got an interest in hashing out ARM relative issues from a tools standpoint.

And that seemed to provoke enought interest from people all over, which is good. This event is definitely going on.
