Re: [OE-core] Changes in Linaro layers for OpenEmbedded
I'll also add that we (the Graphics Working Group) are using it as we're bringing up the graphics stack on ARMv8. Patches soon.

Let me clarify a bit this part since it's Marcin's personal opinion. OpenEmbedded baseline is part of the official Linaro releases. It's maintained, we produce daily builds and test them. As of today, it's mainly used for ARMv8 bring up and is expanded to ARMv7 for covering Toolchain CI. Later on, it's planned to be even more extended for LNG use cases. The team in charge of these builds is Builds and Baselines Team. There's capable people inside the team to take over OE maintenance and that's the plan. In short, I don't expect any disruption for OpenEmbedded baseline builds.

[OE-core] Changes in Linaro layers for OpenEmbedded
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. ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core

No. First Linaro layer for OpenEmbedded was created by Ken Werner from Toolchain Working Group as they considered OE as a test tool. Then AArch64 bootstrap was needed so I stepped in and took maintenance of it (Ken was not at Linaro at that time), added meta-aarch64, cleaned up etc. Those layers are used as part of official Linaro build process. All AArch64 rootfs images are built using OpenEmbedded. Note that this excludes kernels which (for some reasons) were cross built as Ubuntu packages. At Linaro we have many teams and some of them are using OpenEmbedded or will do it soon. One of reasons is lack of ARM big-endian distributions on a market. Look at numbers from git shortlog: Marcin Juszkiewicz (341): Ken Werner (28): Riku Voipio (17): Khem Raj (7): Ricardo Salveti de Araujo (5): Fathi Boudra (2): Ken is not at Linaro, Khem never was and those commits are fixes from him, Ricardo is back at Canonical. Riku has OE knowledge but also lot of other duties. And so far only OpenSUSE has packages for AArch64 mass built while all Linaro tools were made for Ubuntu repositories... ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
