Hello, I've just posted some patches with ARM NEON code to the pulseaudio-discuss mail list (http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-January/01261…) -- this might be of interest to Linaro a stand-alone version of the code is in a Mercurial repo at http://pmeerw.net/hg/pa-neon -- feedback and testing welcome thanks, regards, p. -- Peter Meerwald +43-664-2444418 (mobile)

All our work is distro-agnostic. * sched_mc: should get enabled on all kernels since the core feature is now in mainline. * thermal management: should get enabled as we enable various SoCs in the Linaro kernel with SoC-specific drivers

[PATCH v3 0/4] Add SMDK5250 board support

by Chander Kashyap

This patchset add support for Samsung's SMDK5250 board based on EXYNOS5250 based SoC. It also adds support for MMC SPL booting. The porting is done by Samsung engineers at HQ in System LSI Team. I am contributing in upstreaming the code for the board. Based upon discussions following patches are dropped in this version: Exynos: Add CONFIG_EXYNOS4 Macro to EXYNOS4 based boards Exynos: Clock.c: Replace exynos4 prefix with exynos SMDK5250: enable device tree support is squashed with EXYNOS: Add SMDK5250 board support Chander Kashyap (4): Exynos: Clock.c: Use CONFIG_SYS_CLK_FREQ macro ARM: EXYNOS: Add support for Exynos5 based SoCs EXYNOS: Add SMDK5250 board support EXYNOS: SMDK5250: Add MMC SPL support MAINTAINERS | 1 + arch/arm/cpu/armv7/exynos/clock.c | 215 +++++++++- arch/arm/include/asm/arch-exynos/clock.h | 326 ++++++++++++++ arch/arm/include/asm/arch-exynos/cpu.h | 35 ++- arch/arm/include/asm/arch-exynos/gpio.h | 101 ++++- board/samsung/smdk5250/Makefile | 64 +++ board/samsung/smdk5250/lowlevel_init.S | 528 ++++++++++++++++++++++ board/samsung/smdk5250/mem_setup.S | 600 +++++++++++++++++++++++++ board/samsung/smdk5250/mmc_boot.c | 58 +++ board/samsung/smdk5250/smdk5250.c | 125 +++++ board/samsung/smdk5250/smdk5250_setup.h | 589 ++++++++++++++++++++++++ board/samsung/smdk5250/tools/mkexynos_image.c | 117 +++++ boards.cfg | 1 + include/configs/s5pc210_universal.h | 1 + include/configs/smdk5250.h | 188 ++++++++ 15 files changed, 2931 insertions(+), 18 deletions(-) create mode 100644 board/samsung/smdk5250/Makefile create mode 100644 board/samsung/smdk5250/lowlevel_init.S create mode 100644 board/samsung/smdk5250/mem_setup.S create mode 100644 board/samsung/smdk5250/mmc_boot.c create mode 100644 board/samsung/smdk5250/smdk5250.c create mode 100644 board/samsung/smdk5250/smdk5250_setup.h create mode 100644 board/samsung/smdk5250/tools/mkexynos_image.c create mode 100644 include/configs/smdk5250.h -- 1.7.5.4

Monthly Release Thoughts

by Tom Gall

Hi All, I had some thoughts and a suggestion this morning about the monthly release cycle that I'd like to share. Perhaps I'll get booed off the stage, perhaps not. I'm sure it can be improved on. There is a great deal of stress around what blueprints fit into what monthly release boundary. For deliveries like the LEB that combine the fruits of our Linaro labors this makes great sense. Outside of the process for LEB creation and release, I'd like to suggest it's less than efficient and creates a bit of stress as we have the monthly rush to make the release dates. PMs and TLs continually have to be watching for what will and what won't be making dates that fit with the LEB. This passes on the stress to the engineering team, causes some late night hack-a-thons which in turn I believe caused us to rush software what was less than ready to be included in a LEB. I'm sure we all have examples we could point to. To address this I'd like to suggest the following. The production of the LEB and related builds should continue to be on a monthly release cycle. However outside of that process, for the WGs and such, we should go to a process based on continuous integration. As work groups, landing teams and so on, we commit to the LEB process that we have some set of blueprints IN QUEUE, meaning they are being worked on right now. When they go complete if they are LEB bound, they are delivered to the staging overlay. Items in the staging overlay are candidates for promotion to the overlay. When an item in the staging overlay is judged as being ready (bugs are at least triaged and deemed to not be blocking) it is promoted into the overlay from which daily builds are made and the monthly release is made. Packages in the staging overlay are the subject of functional test.IE Does it work? Packages in the overlay are the subject of integration test. IE Does it break the system? Work Groups, Landing Teams will also commit to having a priority list of blueprints and bugs that are being addressed or will be addressed. This keeps the release process and management team aware of what is coming and when. The # of completed work items per week (or other counts) can also help the management team measure forward momentum and progress. In some respects it's subtle process tweek. But I feel shifting part of linaro to a continuous integration / ship when ready model makes sense. In the work groups we are more connected upstream as we stay tune with upstream release boundaries but still want to showcase results in the monthly LEBs. Likewise focus on the LEB continues with higher quality software. It does shift the goal of creating great software by date X, to creating great software and ship when it's ready. Perhaps this would be a good discussion for 1Q12LC. -- Regards, Tom "Where's the kaboom!? There was supposed to be an earth-shattering kaboom!"

Linaro Connect Q1.12

by Arwen Donaghey

Hi All, You’ll be pleased to see we've now created the e-mail alias for Linaro Connect Q1.12. You can mail connect-q1.12(a)linaro.org for general announcements, and we will also use this alias to advise you of important issues related to and during the event. Everyone who has registered for Linaro Connect Q1.12 is now on this alias. If you’re attending and have not yet registered, please do so asap by clicking this link. ‧ Register for Linaro Connect Q1.12 <http://connect.linaro.org/register-connect/> [1] You’ll also be able to subscribe to sessions at Linaro Connect Q1.12 you are interested in, apply for visas and share travel information with others (may be helpful for sharing taxi rides etc). In addition, please book your accommodation for Linaro Connect Q1.12 before rooms at the hotel run out. As many of you will be staying on for ELC and ABS, we've now updated the accommodation booking link to reflect booking dates from 5th through to 18th February. ‧ Book accommodation for Linaro Connect Q1.12 <http://www.sofitel.com/sofitel/lien_externe.svlt?goto=spec_rate_hotel&sub=I SP&code_hotel=0922&code_chaine=SOF&RA1=lin0502212&RA2=&ragp=0&libelle_tarif= 1&showEco=0&jour_depart=05&mois_depart=02&annee_depart=2012&jour_arrivee=05& mois_arrivee=02&annee_arrivee=2012&nb_nuit=13,> [2] You will see once you've clicked 'recalculate' it states breakfast is not included.

Fwd: Errors in work item definitions

by Tony Mansson

Hi Guys. I get a lot of spam from launchpad whenever the format of a blueprint is not OK. Below is an example. Please don't use colons (as e.g. in an URL) inside work item definitions. There is a low-IQ parser somewhere that gets confused by that.
