[Linaro-dev] Second "Linaro kernel merge result of the moment" aka "arm_next" published

by Nicolas Pitre

I just made available a new Linaro kernel merge result at the following location: http://git.linaro.org/?p=linux/arm_next.git;a=summary The process we're experimenting at the moment for the production of this kernel is described on this page: https://wiki.ubuntu.com/Specs/M/ARMKernelVersionAlignment This is the merge result from the following branches: Linus' v2.6.35-rc5 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6 Ubuntu Maverick at commit 78e9e778 git://kernel.ubuntu.com/ubuntu/ubuntu-maverick.git RMK's devel branch at commit 3712d8e6 http://ftp.arm.linux.org.uk/pub/linux/arm/kernel/git-cur/linux-2.6-arm.git Catalin Marinas' "rebased" branch at commit 3a9a55c7 git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git Will Deacon's "for-linaro" branch at commit 6741018f git://repo.or.cz/linux-2.6/linux-wd.git Uwe Kleine-König's "arm/booting" branch at commit e69edc79 git://git.pengutronix.de/git/ukl/linux-2.6.git (this also contains patches from Eric Miao for automatic ZRELADDR) The security branch was dropped as it has been merged into RMK's devel branch at this point. This has been tagged with "linaro_merge_100712" and the tag message also has the above info. This is also available through the following gitweb link: http://git.linaro.org/gitweb?p=linux/arm_next.git;a=tag;h=linaro_merge_1007… The previous merge result is still available through the tag "linaro_merge_100616" for reference. Please contact me if you have any issue with this tree. Positive feedback is also fine! ;-) Nicolas

[Linaro-dev] Discussion on new ARM hard-float port on debian-arm@

by Loïc Minier

Hi I'm sure people tracking linaro-dev@ will be interested about the ongoing discussion on a new ARM hard-float ABI port which is taking place on the debian-arm@ mailing-list: http://lists.debian.org/debian-arm/2010/07/threads.html#00019 Cheers, -- Loïc Minier

[Linaro-dev] New Linaro Toolchain mailing-list

by Loïc Minier

Hi, A new Linaro Toolchain mailing-list was just created. This list will serve Linaro development, discussions, and planning around the usual bits: GCC, Binutils, GNU C Library / EGLIBC, and GDB bits -- but the list of tools is very open, so LLVM, Valgrind or QEMU are fine topics too! (Discussions around upstream patches or new upstream features should still be preferably done on the respective upstream mailing-lists.) Once they see the new list, I bet the folks from the Linaro Toolchain Working Group will be rushing to subscribe. ;-) You can subscribe from: http://lists.linaro.org/mailman/listinfo/linaro-toolchain Read you there! Cheers, -- Loïc Minier

[Linaro-dev] gcc-linaro branches moved

by Loïc Minier

Hi folks Just a note that gcc-linaro branches have been moved. They used to be owned by the gcc-linaro-dev team, and are now owned by the linaro-toolchain-dev team (used also for binutils, gdb etc.). You can still branch the official aliases: lp:gcc-linaro/4.4 lp:gcc-linaro/4.5 However, if you had pushed to ~gcc-linaro-dev/gcc-linaro/4.4, you have to explicitly push once to ~linaro-toolchain-dev/gcc-linaro/4.4 instead: bzr push --remember lp:~linaro-toolchain-dev/gcc-linaro/4.4 Sorry for the inconvenience. Thanks, -- Loïc Minier

He hasn't managed to boot it yet due to issues. A code review is needed. * [ACTION] Matt to code review the arm_next.git tree and check that all patches are present. * npitre has been working with jk to review his latest round of patches. The process is ongoing and some clean-up is needed. The main problem is that jk's patches depend on some patches from Grant Likely and Grants aren't upstream yet. * jk explained that Grant is working on upstreaming his patches and he foresees no problems. * [ACTION] jk to report on progress of talking to Grant WRT upstreaming his patches. * mwaddel committed to talking to ARM to discuss device-tree work. * [ACTION] mwaddel to talk to ARM about device-tree work. * 3 patches still remain on the boot interface and jk is still working on them. npitre needs to review. * [ACTION] Jeremy to chat with Nicolas about documenting boot interface. * lool asked the working group to email him activity reports weekly to facilitate the production of a weekly report. * npitre didn't manage to complete an action item on the list of trees merged in arm_next.git. This was carried over. * [ACTION] npitre to find a way to expose the list of trees merged in arm_next.git via a wiki page. * [ACTION] npitre to describe the problem he is having with the stack-overflow module and pass this onto a tool chain person for investigation. * jcrigby will take up the packaging of the kernel tree. * [ACTION] jcrigby to talk to slangasek about the list of kernel flavours to produce. ==== Blueprint Status ==== * jk explained that the last week has been spent rebasing his current patches and working with npitre to review them. * He also mentioned that no new hardware had been enabled and will not be until the current patchset is approved. * OMAP3 and OMAP4 is being worked by Linaro and its partners, patches will be fed into the Linaro kernel. * Some partners want complete tree branches merging into the Linaro kernel to enable their new hardware to boot 'out-of-the-box' with Linaro. * davidrusling asked about the status of OMAP WRT to upstream. amitk explained that about 700 patches are not upstream for OMAP4 but OMAP3 is in a much better position. TI have recently added patches for the Panda board to the linux-omap tree. It is understood that around half of the 700 patches will need some work to upstream. npitre said that he is willing to take large chunks of code as long as it merges nicely. * [ACTION] amitk to report back the status on linux-omap's patches. * The issue of keeping a stable kernel tree was discussed. One possible solution was to have two tree's, one that will constantly rebase with upstream and continue to fold new code in with a second tree being more 'tried and tested' which could be used as a basis for release. The details still need working out. * jcrigby is currently packaging Linux versatile but the patches to enable QEMU support for versatile aren't available in Linaro ATM. lool asked if we need to keep versatile support, jk explained that keeping it would be a good idea as its currently used. A final decision needs to be made after investigations. * [ACTION] jcrigby to determine if versatile is still needed. * Arnd Bergmann joined the work group this week, he introduced himself and explained that he would be working on QEMU initially. * Kernel power management discussion will be removed from this work group as it has its own now. * npitre explained that one of his work items on the missing security features was blocking on toolchain support. lool asked npitre to file a bug. * [ACTION] lool to check that -fpie support is currently enabled in the Linaro kernel. * npitre is monitoring ericm's patches for a single zImage kernel. He believes that some patches are simple enough to get upstream. * [ACTION] npitre and arnd to review ericm's single zImage patches. * [ACTION] ericm to send single zImage patches to russelking after they have been reviewed. * mwaddel explained that there is no support for mmc on the versatile express boards. This needed adding. * Future tracking of uboot work will be discussed on the call from the future. * [ACTION] jcrigby and lool to arrange a uboot specific call for interested team members. Regards, Jamie. -- Linaro Release Manager

[Linaro-dev] test-rebuild of maverick (main) using the linaro compiler

by Matthias Klose

A test rebuild of maverick (main) on amd64 and i386 did finish last weekend [1]. - There are a few failures which I could not reproduce on plain maverick (using the maverick GCC). Bug reports are filed for the linaro-gcc project, tagged with `armel toolchain'. - Bug reports for packages which fail to build in maverick [2] are filed for ubuntu with priority high, milestoned to alpha-3. - Some packages are unchecked (uninstallable build dependencies, when the snapshot was taken) [3]. Some issues with our build infrastructure to do test rebuilds on armel will be fixed this week, and the armel test rebuild should start this week.
