Instructions for building Linaro GCC with crosstool-NG

by Michael Hope

I've written some short instructions on using crosstool-NG to build Linaro GCC: https://wiki.linaro.org/WorkingGroups/ToolChain/Using/CrosstoolNg Could someone review these for me please? Linaro GCC is already available in a bunch of places including OpenBricks, crosstool-NG, OpenEmbedded, OpenWRT, and (of course) Ubuntu. I hope to write a short page on each so people know where to find our toolchain in the distribution of their choice. -- Michael

Making linaro-nano smaller or Give Up Disk Space for Lent

by Tom Gall

Hi All, In the developer platforms team we're working on getting the linaro-nano image so that it is considerably smaller. To date I've been using the approach I outlined last fall in a previous post to this list. Some highlights to nano: * The linaro-image boots just as our linaro-headless image did (upstart and friends) * it can be updated, or additional pkgs installed via apt-get * networking works * busybox is in use tho not necessarily universally * ureadahead, python, have been removed * docs have been removed * linux-firmware has been removed (binary kernel firmware blobs) * locales is remove Installed image is 125 Megs. (Down from 290 Meg) We're on the cusp of being able to fit into 128 megs of flash. This brings me to the subject of the kernel. hwpacks besides installing linux-firmware (32 Megs) but also approx 50 Megs in modules. Yet on my beagleboard lsmod notes Module Size Used by asix 12805 0 usbnet 17027 1 asix omap2_mcspi 8441 0 omap_wdt 4093 0 hid_apple 4999 0 twl4030_usb 4950 0 twl4030_pwrbutton 1298 0 gpio_keys 6072 0 leds_gpio 2198 0 usbhid 39072 0 hid 74787 2 hid_apple,usbhid Clearly we don't need all of these modules and I don't think it's an unreasonable change our policy to "build what's needed + some reasonable subset of function that our average user might neeed". I don't know why we're installed the firmware deb, does any of the hardware we're supporting even use that? >From the directories where modules are located there is the following size info: 812 ./crypto 7568 ./net 2456 ./sound 60 ./arch 28372 ./drivers 172 ./lib 272 ./ubuntu 8316 ./fs 48032 . Going deeper it's pretty easy to spot low hanging fruit: >From fs - Do we need afs, jfs, code, minix, hpfs, xfs, hfs, hfsplus, gfs2, reiserfs... I'm thinking no. >From drivers - net and media make about about 1/3rd of the 28 meg in use, I'm sure there's a number of drivers in here that can just be turned off. >From sound - ac97, are there arm boards that use that? >From net - x25, decnet, appletalk ? So that said, what is the best way to proceed? 1) Is there agreement that for all the kernels we supply that we should change the policy for kernel configs to not default to everything on? (Maybe we should be using the upstream config with minimal modifications?) Pro: everyone benefits from the diet Con: Our kernel would be build slightly different than ubuntu's others: 2) Linaro-media-create shouldn't install linux-firmware_1.47_all.deb ? Do we have any any hardware that needs it? If so could there be a --nano option to not install it? 3) linaro-media-create should have some kind of option (--nano) to clear out apt caches (saves ~40 meg of space) Specifically from the installed image after the hwpack deps are installed get rid of the following: rm -f ./var/lib/apt/lists/*Packages rm -f ./var/lib/apt/lists/*Sources rm -f ./var/lib/apt/lists/*Release rm -f ./var/lib/apt/lists/*Release.gpg rm -f ./var/cache/apt/pkgcache.bin rm -f ./var/cache/apt/srcpkgcache.bin Pro: if you never run apt* you won't mind the cold caches Con: if you're running out of nand and you're going to apt-get upgrade your system, you're probably going to run out of space (Probably a problem to solve in a future cycle) It's important through this exercise for people to speak up about what can and can NOT be safely turned off. Thanks for your time, attention, suggestions and feedback. Regards, Tom

[NOTES] 2011-03-11 Engineering Resources weekly meeting

by Matt Waddel

Hi, The minutes from the Engineering Resources team meeting can be found here: https://wiki.linaro.org/Mentoring/Status/WeeklyMeeting/2011-03-11 Summary below. --Matt === Action Items from This Meeting === * AddNewHardware/HardwarePack pages need to explain kernel packages as Steve noted below * HardwarePacks page refers to Maverick instead of Natty * Mentoring section needs to be renamed and back links should be fixed * A better header for wiki that includes things like a "Resources" link in banner/header * Toolchain documentation improvement === Minutes === ==== Feedback from Steve L ==== * No super hot button issues with team * come up with clearer idea of what goes in hwpacks and policies around them * snag with v310 hwpack. needed u-boot not built by John R * missing linux-meta package in their hwpack. package name changes each time ABI is bumped. (Scott has had people confused by Meta-Packages) * Do we need new "types/names" of hwpacks for situations like this * Maybe ER team needs to add some to HWPACK documentation to mention these things. * Scott B - ask Andy Green for feedback on documentation changes * HardwarePacks page refers to Maverick. Should be Natty and probably say "CURRENT RELEASE" * documentation under mentoring. needs to be promoted * rename to how-to * put something on main page and list latest updates * suggestions for front page: * change the way the header looks so that people will actually start to notice it again. Put some main links in this new header * joey links: https://wiki.canonical.com/OEMServices https://wiki.linaro.org/LinaroHeader ==== Feedback from Scott B ==== * cross-compiler documentation is still confusing * break up page by 4.4/4.5 versions into 2 pages. and then versions. * we shouldn't even suggest 4.4. 4.5 is what should be used * explain why you do a add-apt-repository * Cross-development Environment for userspace. There's nothing. We don't have a good story on this. Steve says we're improving so not spend much time trying to explain ==== Feedback from Kiko ==== * echo steve's comments on hwpacks * (scott) naming convention for community/landing team to indicate what is supported ==== Discussion after leads ==== * RequirementsProcessHowto - should be per release for as things change * ProductRequirement is a little off. Its not needed * Joey to ask if 1111 release will just use TechnicalTopics or still do a TechnicalRequirements page

A good skia [was: Re: [RFC] Linaro Toolchain for Android and NDK]

Of course, I could be > over-simplifying here ;-). I'd like to use Skia as a toolchain benchmark but the upstream seems a bit messy. I'm using this export: http://people.linaro.org/~michaelh/skia-0~svn788.tar.xz from http://code.google.com/p/skia/ which I then build and run using these rules: http://bazaar.launchpad.net/~linaro-toolchain-dev/cbuild/trunk/view/head:/l… The code.google version seems a bit broken. autoconf scripts are included but they don't work. The non-autoconf Makefile assumes Intel with SSE2. The Android Skia seems to be a fork from some time ago and uses build scripts that are tightly tied into the Android build system. What's the best version to use? I'd like to standardise across Linaro for benchmarking so that results can be compared across groups, or at least so we don't get confused. -- Michael

storage liability test

by Per Forlin

Hi, I am looking for a test framework to verify liability of I/O storage. Most of the test tool I find focus on performance. I would like to run test that compares in-buffer and out-buffer, use different address and size alignment for in-buffer and out-buffer, runs tests simultaneously on multiple block devices, etc... The test can run on FS level or block level either way is fine. Any suggestions? /Per

[REPORT] 2011-03-10 Validation team weekly report

by Jamie Bennett

Hi, The Validation team weekly report for 2011-03-10 is now available and can be found at: https://wiki.linaro.org/Platform/Validation/Status/2011-03-10 The report is also reproduced in full below. Regards, Jamie. -- Linaro Release Manager | Platform Project Manager -- * Period: (20110302-20110309) * PM: JamieBennett <jamie.bennett(a)linaro.org> * Past reports : https://wiki.linaro.org/Platform/Validation/Status * Burndown information : http://status.linaro.org/linaro-validation.html == Key Points for wider discussion == * A request for comments on the Debian Django packaging guide has been made. Please read and give comments on: http://wiki.debian.org/DjangoPackagingDraft. * Power Management tests are planned to be integrated into the test suite and visualisation tools. The best way to do this is under discussion and the team invites more comments. == Team Highlights == * The Django packaging guideline for Debian was produced and is available at http://wiki.debian.org/DjangoPackagingDraft. There are discussions ongoing on the debian-python mailing list for feedback. * A first (and second) release of the django-debian package was made for connecting django database settings to dbconfig-common. This is being used on the LAVA project for database integration. * Initial discussions have been made to integrate some of the work the Power Management Working Group is doing in to abrek (the test-suite framework) and launch-control (the test visualisation tool). The ability to automatically test and visualise the power consumption on boards will take the Validation team around 2-4 weeks to complete. * Work continues on LAVA with two new branches containing improvements done this week. * abrek gained the ability to save bundles at the end of a test run. == Upcoming Deliverables == * launch-control 0.3c2 deployed on validation.linaro.org == Risks / Issues == * '''HIGH IMPACT''': Zygmunt's Beagle Board C4 appears to have hardware issues (1 week). * '''HIGH IMPACT''': The validation scheduler Blueprint continues to lag behind with 37 work items to complete (none completed so far) - https://launchpad.net/lava/+spec/linaro-n-validation-scheduler (several weeks). Discussions are on going to find a way to unblock this project. == Miscellaneous == * Wiki pages of note this week: * http://wiki.debian.org/DjangoPackagingDraft
