Changes in Linaro layers for OpenEmbedded

by Marcin Juszkiewicz

NOTE: I skipped "openembedded-devel" ML cause most of users of Linaro layers also read OE Core ML. As I will leave Linaro at the end of May I would like to write some kind of summary of current state of Linaro layers for OpenEmbedded. At Linaro we have 3 layers: 1. meta-aarch64 2. meta-linaro 3. meta-linaro-toolchain First one is BSP kind. I know that it had some issues which affected each build which had it in BBLAYERS but I fixed those issues. I would like to thank Khem Raj for pointing me at those. We have git version of binutils there due to some changes which were not present in 2.23 line. But use of this version is not required as builds are fine with OE Core one. We have "tune-armv8.inc" in this layer as well. There was attempt to merge that into OE Core but "/lib or /lib64" discussion started and at that time I decided to skip it. There are similar discussions at GCC and Glibc mailing lists. Once they sort that out OE tune file will be adapted by someone (I hope). Rest of recipes can be split into 2-3 types. Few (like sysprof, emacs) just disable recipes for AArch64. Other have extra patches to add missing functionality or defines. And we have Linaro kernel for AArch64 there. Second layer contains ARMv7a(b) machine definitions used for our machine independent builds and some recipes. There are no patches for OE recipes here. The only exception is busybox where we enable "dpkg(-deb)" command which we need for our tools used to merge rootfs with hardware support. We have "recipes-extra" where we keep new recipes which may not be in a nicest state so are not yet merged into OpenEmbedded (or have no use there like "meta-toolchain-hhvm" one). "recipes-linaro" is for our stuff. Images, automatic root shell on serial port etc. And last but not least is toolchain layer. Everything here is related to gcc-linaro and Linaro binary cross toolchains (armv7a and aarch64 ones). GCC 4.6 and 4.7 is there but 4.6 one will be removed when 4.8 will be added into OE Core. Who will maintain those layers after my leave? This was not decided yet. There are few guys at Linaro who know how to use OpenEmbedded but most of them is outside of Builds and Baselines team. If you have any questions then better ask now.

by Fathi Boudra

Hi, Linaro Ubuntu baseline is now migrated to latest Ubuntu release (13.04 - Raring). Daily hardware packs and rootfs are available as usual on http://snapshots.linaro.org/raring Pre-built images aren't available yet. They will show up soon. Note: Quantal based images won't receive any updates anymore. Cheers, -- Fathi Boudra Builds and Baselines Manager | Release Manager Linaro.org | Open source software for ARM SoCs

Upcoming release.linaro.org migration

by Paul Sokolovsky

Hello, ITS and LAVA teams are finishing preparations to migrate our official releases server, http://releases.linaro.org/ , to the Linaro Cloud. We've scheduled to perform switchover first half of day on Friday, May 10th. This migration probably doesn't affect many people inside Linaro, as day-to-day file publishing activity is centered around http://snapshots.linaro.org/ . There may be some changes which affect Release Team process, and will be communicated separately (please feel free to reply to this mail to be included in the discussion). Thanks, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Working on: - debug & patch cleanup. * QEMU: move CPU migration to vmstate [http://cards.linaro.org/browse/VIRT-73] by Peter Maydell Done. * kernel: agree on a data structure to describe timer state [http://cards.linaro.org/browse/VIRT-42] by Andre Przywara Working on: - Peter pointed to an easy way to implement timer state saving, indeed great idea, started with implementation. * kernel: agree on a data structure to hold GIC state [http://cards.linaro.org/browse/VIRT-44] by Andre Przywara Working on: - starting with VGIC investigation. * ARMv8 KVM QEMU prototype [http://cards.linaro.org/browse/CARD-221] by john Rigby * Add arm64 mach-virt system model skeleton [http://cards.linaro.org/browse/VIRT-53] Done: - wasted a couple of days chasing a bug in my almost working v7 version. - finished that and submitted patches. - no new work on arm64 version yet. * Add creating FDT from scratch to mach-virt system model [http://cards.linaro.org/browse/VIRT-54] Done. * Add kvm guest creation and launching of armv8/mach-virt [http://cards.linaro.org/browse/VIRT-56] Done: - rebased agraf's arm64 patches to upstream and attempted to address all comments to original series. - what is working has been pushed for review. Working on: - finalizing patch submission. * KVM ARMV8 SMP HARDWARE BRING-UP [http://cards.linaro.org/browse/CARD-555] by Anup Patel and Pranavkumar Sawargaonkar Done: - Sent a patch for virtio early printk and related discussions. - Got ARM64 Guest (UP) booting on APM board (UP) with few hacky cache flushes. Managed to get a 64 bit guest prompt with a single cpu host on APM board :) - Submitted arch_timer patch required for APM ARMv8 SOC and - Re-submitted revised arch_timer patch to address reviews & comments. Working on: - Debugging to remove the hacky cache flushes required on APM board. - Try ARM64 Guest (UP) on APM board (SMP). - Continue patch submission for KVM ARMv8 on APM board. * XEN - MULTI-PLATFORM ARMV7 BINARIES [http://cards.linaro.org/browse/CARD-560] by Jullien Grall Done: - clean up xen common tree for ARM. - begin to introduce xen early printk for linux on ARM. - patch series for multiple platform in Xen. - send it and comments are good so far. Working on: - Sending a new version of the patch series. We want to support the arndale board on Xen 4.4 which is due in June. - Use linux 3.9 with the Arndale on Xen. * CI BRING UP: KVM ARMv7 [http://cards.linaro.org/browse/CARD-233] by Riku Voipio Done: - All enablement work. - Real tests to be added in the scope of a new card (to be created). Working on: - Card close out. -- Best Regards, Serge Broslavsky <serge.broslavsky(a)linaro.org> Project Manager, Linaro M: +37129426328 IRC: ototo Skype: serge.broslavsky http://linaro.org | Open source software for ARM SoCs
