Heads up: image builds will not be available on snapshots.linaro.org until tomorrow

by James Westby

Hi all, Due to an ongoing migration in the data centre any image builds that are done from now until sometime tomorrow will not appear on snapshots.linaro.org until tomorrow. Reorganisation as part of the migration means that firewalls need to be updated for the rsyncs to work, and that won't be done until sometime tomorrow US time. Everything should return to normal within 24 hours, and I will update you if that changes. Thanks, James

Launch Control PPA

by Zygmunt Krynicki

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone. With the help of Paul Larson we now have a Launch Control PPA. Currently it does not have the most interesting package (dashboard) but we're slowly getting there. The ppa is at: https://edge.launchpad.net/~linaro-infrastructure/+archive/launch-control I have created a daily build of the first package: python-linaro-json. This package contains the JSON utilities that I've developed for launch control. As soon as the dust settles out and I'm comfortable with packaging I'll release and upload a non-daily build. (Q: what is the best way do to that with launchpad?) Next in the queue for that PPA is a python package for working with dashboard bundle files (extracted from the current dashboard code base). I hope that those two packages can make it to natty eventually and help the nice folks in Ubuntu QA to produce test results not as unstructured text files but as bundle files. Hopefully this will allow them to store those files as they currently do and later on decide to either push them to a dashboard instance of their choice or convert them to launchpad subunit format (yes! it's _should_ be possible to convert all data to subunit) once that is ready for production. Feedback welcome :-) Best regards ZK -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJM0sq1AAoJEKkR4hQBRI+lPgkH+wTHOgbPvPSj6hsA8e2WlB9D 7zgbnZ4JTvmY+6bmDqdzD6obaAHSIlyU1fdNUyoV6MdlahswsnHueS8I55Nya6cd h2ZpURcY9HFnJkbOmW20XBIh2kzIZGmP7tYEnE+iCOGEaULYfZpaoKH8fZlxoEif 6BupMm2bOFnlORP8DXaxb3VgSKEtV5sOjrwYhAx3Uql7qO6notFhBQZVjRdwWXpV aItqkml/K/MxfYdXYjZqtj8FGXrhRlZV+QSASvLJqPIRZJFc96BSmSZ1yv8b6xiX TAxD81gmgmj3SFIrbPAIPkfqb7MApXwXWyjyGdk0gVeJdZYUkNtw3OK9mcNJ5aQ= =QK3g -----END PGP SIGNATURE-----

It might be worth adding these to our enforce system since we want all our kernel flavours to enable these options. Cheers, Amit

Getting code into mainline for 11.05

by Amit Kucheria

Hi, As discussed at UDS/LDS, there is a very good chance that the next Linaro release will be based on kernel version 2.6.38. What that means is that we still have 4-6 weeks to get some code into various maintainer trees before the 2.6.38 merge window opens in early January. If you are working on consolidation of some feature across SoCs, it might be nice to get this code in before then so that we don't have to backport patches for the release. /Amit

[RFC 0/2] Selective identity mapping for kexec

by Per Fransson

Hi, I would appreciate your input on some kexec related changes. When restarting using the kernel kexec functionality the MMU needs to be turned off. Any code which does this needs to use identity mapped addresses to get reliable results. In the ARM kexec case this identity mapping is done: - using the page table of the current task - for all addresses normally used by user space, i.e. 0x00000000-PAGE_OFFSET If kexec is used at a kernel crash to collect a core dump this means that we lose important information. This is what these patches do: * Actually turn off the MMU, which has been omitted by mistake, see this post: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-July/019631.html * Set up a more selective identity mapping * Restore the old mapping once the MMU is off The patch was generated from a linux-next 20101028 with these additional related patches which are in the pipeline: http://dev.omapzoom.org/?p=santosh/kernel-omap4-base.git;a=commit;h=ae360a7… http://dev.omapzoom.org/?p=santosh/kernel-omap4-base.git;a=commit;h=2fd8658… http://dev.omapzoom.org/?p=santosh/kernel-omap4-base.git;a=commit;h=ae69480… Regards, Per Per Fransson (2): Turn off MMU in cpu_v7_reset Selective MMU identity mapping for kexec arch/arm/kernel/machine_kexec.c | 27 +++++++++++++++++++++- arch/arm/kernel/relocate_kernel.S | 23 +++++++++++++++++++ arch/arm/mm/mmu.c | 44 +++++++++++++++++++++++++++++++++++++ arch/arm/mm/proc-v7.S | 4 +++ 4 files changed, 97 insertions(+), 1 deletions(-) -- 1.7.2.2
