[ACTIVITY] w02
* Started with some day-to-day activities in the team. Looking after the proposals and the cbuild scheduler. Will start Created problem log for scheduler problems, there is a link to it from the jobs page. https://wiki.linaro.org/WorkingGroups/ToolChain/SchedulerProblems * Worked on producing graphs for benchmark results using matplotlib. Michael: Would it be ok to put my script in linaro-toolchain-benchmarks/scripts? * Kicked off some benchmarks with gcc-linaro-4.6-2012.01. To start with coremark, eembc, denbench, pybench and spec2000. We will see what's there after the weekend. Variants: os-neon, o2-neon, o3-neon-novect and o3-neon. /Regards Åsa ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain

Microkernel based virtualisation
Amber noticed this on her Twitter feed: a L4 microkernel based para-virtualisation that runs on the A9: http://l4dev.org/ They're currently running the 11.12 LEB on a Versatile Express. The project overview: http://l4dev.org/codezero_overview talks about their 'hyperswitch' method to reduce the para-virtualisation overhead and reduce the number of changes to the Linux kernel. -- Michael ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
Bug triage run-through
Hi Åsa. I've triaged a bug and written down my notes on the way. See: https://wiki.linaro.org/MichaelHope/Sandbox/TriageRunThrough This one turned out to be easy but at least you have the basics. Could you triage the bug for real and see what I've missed? I'm unsatisfied with the result on that bug. The fault is in the Ubuntu Natty compiler which we've long since fixed in Linaro GCC. It would be nice if we could point the bug reporter to an updated GCC. Ask Marcin and Matthias what they think. -- Michael ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
