I'm considering getting a Dell Streak when they release in the USA - probably around the 19th. Does anyone know if that would work for Linaro Dev? Thanks Joel -- The cyder is strong in this one Lord!

Spent a lot of time on trying different patch sets to linoar gcc 4.4, but failures do go away. Checked the build log of ubuntu gcc, and the same failures are there. We decide to leave this ubuntu patch. * Merged 19 ubuntu patches to linaro gcc 4.4. Learn bzr push/merge/branch/commit. Very good version control tool, and well-collaborated with launchpad. * Revert license patch in linaro gcc 4.4. * Merge CS GCC 4.4 patches to CS GCC 4.5. Choose three patches from Julian's ARM patch list. Two of them are committed into CS GCC 4.5. The third is sent to CS internal review. == Misc == * Some meetings on linaro status. = Andrew Stubbs = == GCC 4.4 == * Continued refining the blueprints. We now have the initial 4.4 toolchain delivery blueprint finalised. * Entered bugs for each of the test regressions in the Ubuntu GCC vs. FSF GCC. * Reviewed Yao's launchpad merge request for the Ubuntu GCC patches. It was all good, so I approved the request and did the merge. * Reviewed the ARM test failures to make sure they were what we anticipated they would be. * Reviewed some of the Ubuntu patches marked "Needs review". Decided not to use two, rewrote the third and submitted the new patch for review. Matthias has now accepted it, and applied it to Debian also. * Found out how to create gnu-style release tarballs and wrote a Linaro GCC release procedure document for the wiki. https://wiki.linaro.org/WorkingGroups/ToolChain/GCCReleaseProcess == GCC 4.5 == * Assisted Yao with his patch porting work, and made sure he had things to do. = Loic Minier = * Repaired Beagleboard to boot again * Cross-built ncurses; did other xdeb tests * Added color codes and improved structure of https://wiki.linaro.org/WorkingGroups/ToolChain/UbuntuRegressions and https://wiki.linaro.org/WorkingGroups/ToolChain/UbuntuGCCPatches * Discussed armhf port, started http://wiki.debian.org/ArmHardFloatPort * Started sprint planning and associated wiki pages Bye, -- Loïc Minier

[Linaro-dev] Mugshots

by Michael Hope

I'm terrible with faces and worse with names. I couldn't resist knocking up a quick set of flash cards: http://wiki.seabright.co.nz/linaro-boo/ This is generated from the Engineeering Team wiki page by a simple Python script. Let me know if you want to be removed. -- Michael

[Linaro-dev] Removing Subject: prefix on mailing-lists

by Loïc Minier

Hey I don't quite like the [Linaro-foo] prefix which our mailing-list software adds to all emails' Subject: line. They clutter the subject to make filtering easier, but the list software also adds a List-Id header. Would anybody mind if we were to remove them? Thanks! -- Loïc Minier

[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
