ANNOUNCE: updated live-build with cross support

by Tom Gall

Hi All, In ppa: tom-gall/packages I've published an updated version live-build (version a40-1linaro10) for maverick, natty, oneiric, and precise. This version of live-build includes the ability to cross build root file systems with multistrap. As it turns out to cross build our precise linaro images for nano and developer, one only needs to change one parameter to enable cross builds. The "beta" instructions are as follows: 1) add-apt-repository ppa:tom-gall/packages 2) apt-get update 3) apt-get install live-build This will work for maverick, natty, oneiric and precise. It will install version: ~a40-1linaro10 4) mkdir dirforbld ; cd dirforbld 5) bzr branch lp:~linaro-maintainers/linaro/live-helper.config.precise.nano config or bzr branch lp:~linaro-maintainers/linaro/live-helper.config.precise.developer config 6) cp config/conf_create.sh . 7) edit conf_create.sh : change parameter to --bootstrap from debootstrap to multistrap 8) add / remove packages listed in config/package-lists/nano.chroot.list which is a text file. One package per line. 9) sh ./conf_create.sh 10) lb build 11) When rebuilding use the command : lb clean --all ; lb clean --cache; rm -rf .stage/* ; lb build -- Regards, Tom "Where's the kaboom!? There was supposed to be an earth-shattering kaboom!"

linaro-androidization-tracking

by Andy Green

Hi - Alexander was asking how linaro-androidization-tracking is maintained (hope you are feeling better Alexander). I made a 90-slide presentation about it at the last Connect, you can find the slides here http://people.linaro.org/~andygreen/lttools-introduction.pdf and the tools here http://git.linaro.org/gitweb?p=people/andygreen/lt-tools.git;a=summary In a nutshell common-3.0 from Google is a history tree, so detecting new patches on there is clear enough. John Stultz saw it had come back recently and dropped me a note it had been updated. I asked Jassi to isolate the new patches and send them to me. I use lt-tools to distribute any new patches between the topics, then reapply it to my android-ready branch and confirm it builds and works before pushing. lt-tools also takes care of the tracking action, it's important everything is on the same Linus HEAD basis so I routinely rebase linaro-androidization-tracking along with my other tracking branches, as of last week it's on 3.2-rc4. Actually, l-a-t is low maintainence since it's far from every day new patches are coming on common-3.0, and so far on 3.2 cycle there was no serious uplevel conflict between the androidization patch load and Linus HEAD changes. If we have someone else now who wants to maintain it, I think that's fine with the provisos we should maintain the topic structure and look at further refactor there, and we need a new approach to deal with rebase points that more than one tree can rendezvous at ---> Right now when my tracking branches are in as reasonable a shape on one Linus HEAD basis as they will get, I randomly pull a new basis from what happens to be on Linus' tree that moment, and rebase everything on my side against that (including up until now l-a-t at the same time). That won't really scale to other LTs and WGs all randomly sampling Linus HEAD at different random points as their basis. Scott mentioned that there's a desire to see more KWG content at least on tracking, I think that's a great idea. One way to solve both those problems would be to no longer have LTs base off Linus HEAD but from a new tree which is Linus HEAD + "linux-linaro-tracking", as it were, with these other topics already merged in. So long as this rebases against Linus HEAD really often, like daily at least in the early -rcs, carrying its topic content with it, and matching linaro-androidization-tracking is available, that would be a good way for all the LT trees to both get any Linaro-specific content and increase their chances of having a common "rendezvous" basis where multiple LT trees can be bound together. -Andy -- Andy Green | TI Landing Team Leader Linaro.org │ Open source software for ARM SoCs | Follow Linaro http://facebook.com/pages/Linaro/155974581091106 - http://twitter.com/#!/linaroorg - http://linaro.org/linaro-blog

[PATCH 0/3] Moving xusbxti clock setting in clock.c file.

by Pankaj Dubey

Since there is code duplication in different mach-board.c file it is better to set default clock rate of xusbxti clock in plat-s5p/clock.c file. The patches are based on following commit on Kukjin's for-next branch. Pankaj (1): ARM: S5P: Set default rate of xusbxti clock Pankaj Dubey (2): ARM: EXYNOS: Removed code for setting clock rate of xusbxti ARM: S5PV210: Removed code for setting clock rate of xusbxti arch/arm/mach-exynos/mach-nuri.c | 1 - arch/arm/mach-exynos/mach-origen.c | 1 - arch/arm/mach-exynos/mach-smdk4x12.c | 2 -- arch/arm/mach-exynos/mach-smdkv310.c | 1 - arch/arm/mach-s5pv210/mach-goni.c | 1 - arch/arm/plat-s5p/clock.c | 1 + 6 files changed, 1 insertions(+), 6 deletions(-) -- 1.7.4.1

[ANNOUNCE] Xen port to Cortex-A15 / ARMv7 with virt extensions

by Stefano Stabellini

Hi all, a few weeks ago I (and a few others) started hacking on a proof-of-concept hypervisor port to Cortex-A15 which uses and requires ARMv7 virtualization extensions. The intention of this work was to find out how to best support ARM v7+ on Xen. See http://old-list-archives.xen.org/archives/html/xen-arm/2011-09/msg00013.html for more details. I am pleased to announce that significant progress has been made, and that we now have a nascent Xen port for Cortex-A15. The port is based on xen-unstable (HG CS 8d6edc3d26d2) and written from scratch exploiting the latest virtualization, LPAE, GIC and generic timer support in hardware. We started the work less than three months ago, but the port is already capable of booting a Linux 3.0 based virtual machine (dom0) up to a shell prompt on an ARM Architecture Envelope Model, configured to emulate an A15-based Versatile Express. In this context, we wanted to thank ARM for making the model available to us. Now we are looking forward to porting the tools and running multiple guests. The code requires virtualization, LPAE and GIC support and therefore it won't be able to run on anything older than a Cortex-A15. On the other hand, thanks to this, it is very small and easy to read, write and understand. The implementation does not distinguish between PV and HVM guests: there is just one type of guests that would be comparable to Linux PV on HVM in the Xen X86 world, but with no need for Qemu emulation. The code only requires minimal changes to the Linux kernel: just enough to support PV drivers. Even though we are currently targeting Versatile Express and Cortex-A15 we do intend to support other machines and other ARMv7 with virtualization extensions CPUs. We are also looking forward to ARMv8 and 64 bits support. Given that porting Xen to Cortex-A15 could be done with so little code, we believe that the best course of action is to merge it into xen-unstable as quickly as possible. There are still few rough edges to sort out but we should be able to produce a clean and digestible patch series for submission to xen-devel within the next couple of months. I hope to see the first patches going to the list as soon as possible. We would very welcome any contributions, in the form of testing, code reviews and, of course, patches! A git tree is available here: git://xenbits.xen.org/people/sstabellini/xen-unstable.git arm the gitweb url is the following: http://xenbits.xen.org/gitweb/?p=people/sstabellini/xen-unstable.git/.git;a… And here is the full diff: http://xenbits.xen.org/people/sstabellini/diff We want to point out that this effort is in addition to Samsung's ongoing efforts to upstream Xen ARM to xen-unstable. Samsung's XenARM port allows virtualization of Xen on ARM CPUs prior to virtualization extensions and supports traditional PV guests. I would like to thank Tim Deegan and Ian Campbell: if you spend some time reading the history, you'll see that this project wouldn't have been possible in such a short time without great contributions from them. Cheers, Stefano

[PATCH] thermal: Add a new trip type to use cooling device instance number

by Amit Daniel Kachhap

This patch adds a new trip type THERMAL_TRIP_STATE_ACTIVE. This trip behaves same as THERMAL_TRIP_ACTIVE but also passes the cooling device instance number. This helps the cooling device registered as different instances to perform appropriate cooling action decision in the set_cur_state call back function. Also since the trip temperature's are in ascending order so some logic is put in place to skip the un-necessary checks.

cpu_idle?

by Zach Pfeffer

Amit/Mounir, What's your guys plan with cpu_idle for each board? Are you going to try and upstream a solution that will work across all boards? Would you or Mounir be open to filing a BP per board so we can track when cpu_idle will hit each board? Does it make sense to prototype something across each board that we could land in Ubuntu and Android?
