4.6 merge: ARMv5 sync_synchronize failures

by Yvan Roux

Hi, the issue seems indeed to be introduced by r193959 and fixed in r194161, as it is reported in: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55571 Unfortunately, my merge attempt was at r190461 :( I redo the merge... Yvan

* https://blueprints.launchpad.net/linaro-toolchain-misc/+spec/webp-upsamplin… - working 'fancy' upsampling, actual yuv-rgb conversion still major time hog - next: do yuv-rgb conversion in neon * reported valgrind bug https://bugs.kde.org/show_bug.cgi?id=311318 * implemented runtime cpu feature (neon, vfp, etc) detection in Libav * ongoing: tracking gcc trunk on Libav test systems, no ARM regressions this week * user support on irc -- Mans Rullgard / mru

Summary: * Validate RM toolchain, Linaro QENU 2012.12 and Linaro aarch64 2012.11. * Collect performance data for different branch cost. Details: * Validate RM toolchain release. * Set up test environment with the help of Michael and validate Linaro QEMU 2012.12 release. * Validate aarch64 toolchain 2012.11. From 2012.12, it will be released regularly like arm-linux-gnueabihf toolchain. * Collect denbench and spec2000int performance data for branch cost tuning. * Investigate how to do copy propagation for shrink-wrap to optimize 453.povray benchmark. Will reuse current codes in pass_cprop_hardreg. Plans: * Performance reports for branch cost tuning. * Fix README issue (lp:1068402) in Linaro crosstool-ng. Best regards! -Zhenqiang

What tools can be used to protect the KVM and qemu quality？

by chenq

Hi all， I am a rookie, and now I'm focusing on ARM virtualization. As we know,KVM (for Kernel-based Virtual Machine) is a full virtualization solution. KVM-Autotest is a set of virtualization tests for X86 platform, but it may not be suitable for ARM.I want to know, in the linaro , what tools can protect the KVM and qemu quality ? Thanks and Regards,Qun Chen

* usual set of meetings etc * rebased qemu-linaro on upstream 1.3, rolled tarball for 2012.12; Zhenqiang has tested it and it should be ready to go next week * qemu arm patch catchup; pinging or resending some patches of mine from before upstream freeze * applied a set of boot-wrapper patches from tixy * virtio patch code review: design definitely coming together now KVM blueprint progress tracker (note new url): http://cbuild.validation.linaro.org/helpers/backlog?group_by=topic&colour_b… -- PMM

== Progress == * Turn off 64-bits bitos in Neon: Ping-ed patch proposal. * Disable peeling: benchmarks show good results; sent a proposal upstream to discuss preliminary implementation & needed testsuite modifications. * builtin_bswap16 backport to linaro-4.7: need to investigation an unexpected regression reported for i686 target. * Updated gdb linaro sources to 7.5.1, exercising the release process. * Trying to bootstrap gcc-linaro/4.7 on board: need to retry with a different rootfs distribution. == Next == * handle 64-bits bitops in Neon and disable-peeling feedback from upstream if any. * finish builtin_bswap16 backport

Scheduler tweaks

by Michael Hope

I've done a couple of tweaks to the scheduler. You now see pending jobs by the class of machine they'll run on. Clicking a job takes you to the detail, which includes a link to drop/cancel the job. -- Michael
