Virtual Connect Aftermath
Hello there, Last week we ran a series of open sessions as part of an experimental Virtual Linaro Connect schedule; the blog post announcing it is at: http://www.linaro.org/linaro-blog/2012/08/07/linaro-announces-virtual-connect-q3-12-13-17-august-2012/ We ran all the sessions successfully over a combination of Google Hangouts, IRC and Etherpad, and the videos are now all available for your review and comments at: http://www.youtube.com/channel/UCIVqQKxCyQLJS6xvSmfndLA?feature=guideo If there anything on the menu that interests you, it's worth taking a look at the sessions. The minutes linked to from the video pages are also a good trove of information and can be used to follow the dialogue which is sometimes a bit tricky. We're considering running a wider Virtual Connect now that this one has concluded successfully; I'd love to hear your feedback on how it went and what you'd like to see us do differently for future events.

But since Google's interest is in the case it is configured, I doubt they took care about having it disabled well. For new or optional functionality, this is usually the case, but not for all changes. Having multiple config based code paths has additional maintainance burden, so frequently if a change really should be generic there isn't any need for a config. The simplest example of this are bug fixes, which shouldn't be configurable off :) For an example we had a problem yesterday with the Androidization interactive cpufreq governor turning up unexpectedly in an Ubuntu build and spamming block task logs. I dunno why it appeared yet, maybe it's marked up as defauly=y or some config fumble on part of guy who built the kernel. Generally when analyzing a situation like this I think the first question is whether feature X will be merged upstream, and then the question is whether it would be protected by CONFIG_ANDROID. How does the interactive governor fair against this criteria? Will it be accepted upstream, and if so, will it be behind CONFIG_ANDROID=y? Initially we added without discrimination that 7 year old patch that turns dmesg into junk to llct because it came in with Google's Androidization series. It suggests we're just shovelling them on without any plan at the moment. And I'd say in this case things worked ideally! Android tree had a very old hack that has since become obsolete. You noticed it in the tree and Yeah but that's what I am saying, we shovelled the patches on with no plan about assessment or audit and just waited for trouble. It's fair enough to do that on android-specific tree because it's for benefit of Android guys. But some vanilla people don't want to participate in finding bugs from non-mainline Android code they don't care about. Am I right in thinking the issue you're running into here is that your customer has direct expectations for the tree you're maintaining, which makes adding unexpected instability on a vanilla build very undesireable? (If that's not the case, then generally I don't see a problem with broadening the group testing the Androidization patches to the vanilla set -- they will be beta testing, but that's one key part of open source QA.) Personally I like the idea of the Androidization becoming part of the basis because it puts us in generally converged direction with mainline. But then we have a responsibility to make it as transparent as mainline will insist that it is if we expect members are seriously going to offer vanilla kernels on this basis. I like it too. What could we do cheaply that will give us the transparency or policy that addresses the risk you've outlined? -- Christian Robottom Reis, Engineering VP Brazil (GMT-3) | [+55] 16 9112 6430 | [+1] 612 216 4935 Linaro.org: Open Source Software for ARM SoCs ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

You like it complicated, eh? Why do you introduce a function which sets
a variable...
This complication is used to deal with the timing of various levels of
init calls. More explanation below.
Regardless of how you end up solving this, it's probably a good idea
to document the rationale, perhaps cribbing from what you describe
below..
If I called imx_cpuidle_init directly from imx5 or imx6q init
routines, it would be getting called before the coreinit_call of core
cpuidle causing a failure. There were various other directions to
take and all seemed less desirable than this one.
One alternative would be to add a function to return the pointer to
the cpuidle driver object based on the machine type. Functionality
exists to identify imx5 as a machine type but not imx6q, so I couldn't
use that machine based method without adding that extra code.
Another alternative would be to add a general platform lateinit_call
function to each platforms that support cpuidle.
..in a comment; without it, the code indeed looks bizarre.

It's a new SoC which will have its own arch/arm/mach-xxx directory You haven't stated clearly your intention -- is it your first priority to have support for this platform included in Linus' mainline, or are you more interested in the bring-up for a product goal? So my questions are 1. Is this a rational approach? IMHO, you should be developing against mainline, say the last released kernel 3.3, if tracking 3.4-rc is too much. And then ask for it to be merged via the arm-soc tree if you have no other sub-arch maintainer above you. It is not feasible to track the tip mainline release both because it eats up man power in the kernel team but even more so in the QA team. Probably looking at one kernel release per year, ideally based on the long term kernel, currently 3.0. Based on your answer, I am guessing the latter option of the two I outlined above. When it comes to mainlining, is arm-soc the best way? There is no route via Linaro? That's correct -- the linux-linaro kernel is an integration tree, intended to validate and test cutting edge work happening in both working groups and member SoC and board bring-up. If you want to produce something suitable for mainline, you should base on trunk and uplevel your patches as mainline progresses. In other words, the linux-linaro kernel isn't intended to be a base for /SoC bringup/ efforts [*]; it's much better for you to track trunk and bring in specific branches that you care about. Note that I would certainly not start on 3.0, which is getting old very quickly. If you absolutely care about starting from a stable base, then I would start on the latest released kernel (currently 3.3); the state of things in ARM are such that every release you go backwards causes you to miss critical plumbing that we are working on. If you need specific features from the Linaro tree, you should use git branches to track the tree and cherry-pick the bits that you do need. Can you give examples of things that you do need from the Linaro tree? Basically, everything in arch/arm/kernel, arch/arm/mm, etc. Right now the diff is mostly to do with device tree, which is interesting but not crucial. But the principle is that linux-linaro will have arm architecture support before mainline, no? Yes, but you shouldn't base your work on linux-linaro, and instead on the topic branches that you care about -- basing your work on a history tree is going to lead to a path of tangled patches that will be much harder to upstream. A manifest of the branches being included in linux-linaro will be available online shortly; I'm waiting for Andrey (copied here) to publish that. [*] The complementary question is what /is/ linux-linaro for, if not to support new SoC bringup. The answer is that it's there to allow people to test cutting edge kernel work on Linaro member platforms -- for instance, if you want to verify how well Device Tree support works on an i.MX53 Quickstart, or how well the latest eMMC 4.5 storage patches work on Exynos. -- Christian Robottom Reis, Engineering VP Brazil (GMT-3) | [+55] 16 9112 6430 | [+1] 612 216 4935 Linaro.org: Open Source Software for ARM SoCs ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

I think this is indeed very good material for discusing with Ubuntu. Do we have a session scheduled with them to talk about this?

Yes, currently missing ARM NEON optimizations for chroma upsampling/downsampling and grayscale color conversions definitely affect the tjbench results for subsampled formats and grayscale. Also huffman decoder optimizations (which are C code, not SIMD) in libjpeg-turbo seem to be providing only some barely measurable improvement on ARM, while huffman speedup is clearly more impressive on x86. This gives libjpeg-turbo more points over IJG jpeg on x86 as a result. We should definitely consider these for future work, then.

The Value of Thumb-2
Hello there, Coming back from Asia I've been putting a lot of thought about how we can make sure we spend our engineering cycles on the work that is most valuable to the current Linaro members, and part of that means reassessing assumptions that we've carried since our foundation. The first point I want to raise is Thumb-2, the alternative ISA described by ARM like this: For performance optimised code Thumb-2 technology uses 31 percent less memory to reduce system cost, while providing up to 38 percent higher performance than existing high density code, which can be used to prolong battery-life or to enrich the product feature set. Thumb-2 technology is featured in the processor, and in all ARMv7 architecture-based processors. We've from the beginning set Thumb-2 in our standard configuration across platforms, but outside of Ubuntu, I think we're unique in that. So the questions I have are: - Do we know how much better Thumb-2 actually is, in practice? It's easy for us to confirm this on Android; what do the numbers and feel of the system tell us? - What are the downsides to using Thumb-2 in general? Do we have anecdotes or threads that talk about bad experiences or blockers in the transition? - If it's so great, how could we lead a wide-ranging transition to Thumb2 becoming the standard ISA for modern v7 applications, including Android, Yocto and anything else relevant that runs on a Cortex A?

There is no benefit to v8. v7 added support for the rarely/never used arithmetic coding option, left out of earlier versions due to patent issues. Since nobody uses this mode, supporting it is irrelevant. v8 only adds some experimental, non-standard coding options even less relevant to any real-world uses. What is relevant is, however, that v8 is significantly slower than v6 in the default configuration. I don't remember if this slowdown was present already in v7.

Re: Fwd: Would you send me your hard float experiment results you presented in Budapest?

Hmm, but the email seems to not actually contain a hard-float run. Or am I misreading what he means by Fixed vs VFP? I believe that the conclusion was that skia and webkit may benefit, but that such benefits would impose an undue burden on Android's distribution model which tries to create libs that can run on as many architectures as possible. You may be confusing things here. Hard-float is a pure software ABI change, and any platform which supports VFP can use it if you build it that way. However, since it is an ABI change it requires that hard-float libraries be available. What /would/ stop code from running on certain platforms is using NEON (it would exclude the Tegra2 and some existing Marvell v7s).

It's currently very simple, and hopefully we'll get it more detailed in the future. Feedback is welcome! Oh, this is excellent. Thanks for putting the effort into the write-up. All I need now is an actual board to tell you how well it works ;-) I had one comment, which is that the Downloading Hardware Pack section seems to only specify the lt variant; does it make sense to also point to the pure upstream variant for comparison (or for people that are hell-bent on an upstreamable kernel?) Also, there is nothing mentioned in the text about the bootloader (what comes on the board, and what the default boot media ordering is, and how to replace it).

We fork Android and everything else all the time; we then proceed to send the patches upstream and help them through the process, and so for me the fork is more like a cooperative branch. Look, this is a weird conversation and I want to get out of it as soon as I can. But you guys are overblowing the issue -- I'm just suggesting that if the patch will take a while to go upstream, you can ship a separate repo tool. We do this all the time in Linaro (just look at www.linaro.org/downloads). It doesn't mean the patch won't go upstream eventually, nor that you won't find another solution -- it just means this thread can end and we can go on working without getting other teams all excited about having to change their source control working models. -- Christian Robottom Reis, Engineering VP Brazil (GMT-3) | [+55] 16 9112 6430 | [+1] 612 216 4935 Linaro.org: Open Source Software for ARM SoCs ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
