Announcing the Linaro 2.6.35 "stable" kernel

by Nicolas Pitre

There is now a "stable" 2.6.35-based Linaro kernel repository now available from: git://git.linaro.org/kernel/linux-linaro-2.6.35.git http://git.linaro.org/gitweb?p=kernel/linux-linaro-2.6.35.git;a=summary Unlike the linaro-next tree which will continue to evolve and be rebuilt with the merge of latest developments, the stable 2.6.35 repository won't be rebased and will only include bug fixes and material really considered stable and non intrusive from now on. This linaro-2.6.35 tree is currently made of: - The official 2.6.35 kernel from Linus of course; - The latest Linaro merge tagged linaro_merge_100811 previously announced here; - The upstream stable branch up to 2.6.35.3; - A fix for symbol offset breakage with separated debug in perf by Dave Martin; - The small change required to enable ASLR on PIE executable text segments. Please report any problem with this tree as always. Nicolas

Git repository shuffling on git.linaro.org

by Nicolas Pitre

As discussed between Loïc, John and I, some kernel repositoryes have been moved around on git.linaro.org to better reflect their usage, and to give them more "official" sounding names. Unless people really complain, I don't think this is worth adding backward compatibility symlinks at this point, as this would only clutter the namespace for little gain. It should be easy for people to simply edit their .git/config file within the clones of those repositories and adjust the affected URLs. For example: git.linaro.org/linux/arm_next.git is now git.linaro.org/kernel/linux-linaro-next.git John Rigby's Ubuntu packaging of the above are now found at: git://git.linaro.org/ubuntu/linux-linaro.git git://git.linaro.org/ubuntu/linux-meta-linaro.git I also created a people/ directory under which all personal trees can be accessed. Hence I'd ask those of you (amitarora, amitk, arnd, jcrigby, lool) to remove those symlinks from Git's root repo directory at your earliest convenience. Those personal repositories may now be accessed by adding "people/" in front of the path component of the Git URL. Nicolas

new more official sounding linux and u-boot git trees and u-boot release plans

by John Rigby

I have moved the linux-linaro, linux-meta-linaro and u-boot-linaro git trees on git.linaro.org out from under my directory to their own directories to make it obvious that they are official trees and not my personal development trees. The lnux and linux meta trees are now: git://git.linaro.org/linux-linaro/linux-linaro.git and git://git.linaro.org/linux-linaro/linux-meta-linaro.git The u-boot tree is now: git://git.linaro.org/u-boot-linaro/u-boot-linaro-next.git As the -next implies, this tree has branches that get rebased periodically to current upstream plus extra patches. We will soon have a -stable tree based on a recent official upstream release. My preferred plan for our first -stable tree is for it to be based on the upcoming v2010.09 upstream release. The anticipated release date for v2010.09 is September 12, 2010. If this proves to be too late then we will base the first stable release on a v2010.09-rcN release or on v2010.06 plus cherry-picked patches. Questions/comments are welcome. Thanks, John

by Scott Bambrough

The weekly report for the Linaro Infrastructure team may be found at: Status report: https://wiki.linaro.org/Platform/Infrastructure/Status/2010-08-12 Burndown chart: http://people.canonical.com/~pitti/workitems/maverick/arm-infrastructure.ht… Progress: * LEP/DerivativeDistributions: Backend work under way. UI mockups look good. User testing should be finished early next week, and then frontend implementation will start. * arm-m-private-archive-hosting-infrastructure: Navigation work completed in vostok. Work to allow custom images. Basic preparation for implementing new views in vostok. Plugging away at work items. * arm-m-derived-archive-rebuild: Slow progress on the archive deletion due to detailed DB work, and slow turnaround for checking changes when doing DB work. * arm-m-image-building-tool: Blueprint's one remaining work item postponed. Blueprint now complete. * arm-m-image-building-console: Working on getting several branches landed. All security reviews complete, no surprises. New name for release to be chosen by beta time. Started talking about documentation. Postponed anything not necessary for open sourcing. * arm-m-automated-testing-framework: License approved. Added support for subcommands. Looking at test suites and benchmarks with eye to correctness on ARM and inclusion in the test framework. * arm-m-validation-dashboard: License approved. Working on getting changes landed. Will start new work items when this happens. * hardware-packs: New spec. https://wiki.linaro.org/Platform/UserPlatforms/Specs/10.11/HardwarePacks. Spec done, implementation to start next week. Cheers, Scott -- Scott Bambrough <scott.bambrough(a)linaro.org> Linaro Infrastructure Team Lead

FW: [RFC PATCH 00/14] Versatile Express device tree port

by Dave Martin

Hi all, Lorenzo has posted his Versatile Express fdt support work to the devicetree-discuss mailing list, copied below. Be aware that this is still under discussion upstream, and very much a work in progress. There may be significant rebasing / fixes... so don't rely on it to be stable ;) Cheers ---Dave > -----Original Message----- > From: Lorenzo Pieralisi > Sent: 18 August 2010 20:00 > To: devicetree-discuss(a)lists.ozlabs.org; grant.likely(a)secretlab.ca > Cc: linux(a)arm.linux.org.uk; nico(a)fluxnic.net; Catalin > Marinas; Philippe Robin; jeremy.kerr(a)canonical.com > Subject: [RFC PATCH 00/14] Versatile Express device tree port > > This patchset provides an initial version of device tree > enabled kernel on an ARM Versatile Express board.

linux-meta-linaro pull request

by John Rigby

Tim, By changing the name of the linaro linux meta package to have linaro at the end we can run the image builder with out modification. This patch also takes into account the flavour name changes in the latest linaro kernel pull request. In the process I re-wrote some history rewriting so the basis is Ubuntu-2.6.35.15.16: The following changes since commit 7b6185a7652f8309dcf9a46b96766b29bf33f338: Leann Ogasawara (1): UBUNTU: Ubuntu-2.6.35.15.16 are available in the git repository at: git://git.linaro.org/jcrigby/linux-meta-linaro.git master John Rigby (2): LINARO: Linaro-2.6.35.1000.1 LINARO: Linaro-2.6.35.1001.2 Tim Gardner (1): Dropped linux-source, linux-linaro-omap, linux-linaro-vexpress Makefile | 4 +- meta-source/debian/changelog | 502 +----------------------------- meta-source/debian/control.common | 51 +--- meta-source/debian/control.d/generic | 47 --- meta-source/debian/control.d/generic-pae | 47 --- meta-source/debian/control.d/omap | 17 +- meta-source/debian/control.d/server | 47 --- meta-source/debian/control.d/versatile | 26 -- meta-source/debian/control.d/vexpress | 17 + meta-source/debian/control.d/virtual | 26 -- 10 files changed, 30 insertions(+), 754 deletions(-) delete mode 100644 meta-source/debian/control.d/generic delete mode 100644 meta-source/debian/control.d/generic-pae delete mode 100644 meta-source/debian/control.d/server delete mode 100644 meta-source/debian/control.d/versatile create mode 100644 meta-source/debian/control.d/vexpress delete mode 100644 meta-source/debian/control.d/virtual

linux-linaro pull request

by John Rigby

Tim, Members of the Linaro team have requested that the string "linaro" be included in linaro kernel package names just before the flavour name. I found the simplest way to do that to just change the flavour names to linaro-omap and linaro-vexpress. The following changes since commit 26a7c8433567f66ac96522a2bfeea922bfb57795: John Rigby (1): LINARO: Linaro-2.6.35-1001-5 are available in the git repository at: git://git.linaro.org/jcrigby/linux-linaro.git linaro John Rigby (3): LINARO: Start new release LINARO: prefix flavours with linaro- LINARO: Linaro-2.6.35-1001-6 debian.linaro/abi/2.6.35-1000.4/abiname | 1 - debian.linaro/abi/2.6.35-1001.5/abiname | 1 + .../armel/omap => 2.6.35-1001.5/armel/linaro-omap} | 581 ++++++++++---------- .../armel/linaro-omap.modules} | 0 .../armel/linaro-vexpress} | 579 ++++++++++++-------- .../armel/linaro-vexpress.modules} | 37 ++ debian.linaro/changelog | 9 + ...fig.flavour.omap => config.flavour.linaro-omap} | 0 ...our.vexpress => config.flavour.linaro-vexpress} | 0 .../control.d/{vars.omap => vars.linaro-omap} | 0 .../{vars.vexpress => vars.linaro-vexpress} | 0 debian.linaro/d-i/kernel-versions.in | 4 +- debian.linaro/rules.d/armel.mk | 2 +- 13 files changed, 688 insertions(+), 526 deletions(-) delete mode 100644 debian.linaro/abi/2.6.35-1000.4/abiname create mode 100644 debian.linaro/abi/2.6.35-1001.5/abiname rename debian.linaro/abi/{2.6.35-1000.4/armel/omap => 2.6.35-1001.5/armel/linaro-omap} (96%) rename debian.linaro/abi/{2.6.35-1000.4/armel/omap.modules => 2.6.35-1001.5/armel/linaro-omap.modules} (100%) rename debian.linaro/abi/{2.6.35-1000.4/armel/vexpress => 2.6.35-1001.5/armel/linaro-vexpress} (95%) rename debian.linaro/abi/{2.6.35-1000.4/armel/vexpress.modules => 2.6.35-1001.5/armel/linaro-vexpress.modules} (97%) rename debian.linaro/config/armel/{config.flavour.omap => config.flavour.linaro-omap} (100%) rename debian.linaro/config/armel/{config.flavour.vexpress => config.flavour.linaro-vexpress} (100%) rename debian.linaro/control.d/{vars.omap => vars.linaro-omap} (100%) rename debian.linaro/control.d/{vars.vexpress => vars.linaro-vexpress} (100%)
