Board Support Review deadline this Thursday 24th February

by Jamie Bennett

Hi, Along with Feature Freeze [1], Thursday sees Linaro's Board Support Review deadline. This deadline marks the start of the process to define exactly what hardware will be enabled in the final Linaro Evaluation Builds released at the end of the cycle [2]. This review is to ensure that the target hardware support is progressing as expected and that the final user experience will shine on these boards. For more information on the Board Support Review deadline please see the Linaro wiki at: https://wiki.linaro.org/Process/Cycle/BoardReview There will be another review on 2011-03-24 where the list will be refined if necessary. A list of boards that Linaro expects to enable this cycle will be circulated after the review. Regards, Jamie. -- Linaro Release Manager | Platform Project Manager Office: +44 1761 348 220 | Mobile: +44 7962 259 437 [1] http://lists.linaro.org/pipermail/linaro-dev/2011-February/002702.html [2] https://wiki.linaro.org/Releases/1105

Please reply if you got a U8500 board

by Per Forlin

Hi, Dave told me he got 3 u8500 boards but no UART break out board. From what I have heard the u8500 boards for Linaro should come with a full kit including power supply and UART. If you have a u8500 board please let me know if it contains a UART break out board or whether it is missing. Thanks, Per

Feature Freeze this Thursday 24th February

by Jamie Bennett

Hi, Thursday 24th February is Feature Freeze. This is a point in the Engineering Cycle [1] where we stop taking new features and concentrate on fixing bugs. Please get your new features (as defined by new packages, API changes, additional features) proposed and uploaded to the archive as soon as possible. If you know of any features that will not make the deadline please make the Release Manager (me) aware of these and be prepared for the Feature Freeze Exception Process, an explanation of which can be found at: https://wiki.linaro.org/Process/Cycle/FreezeExceptionProcess To read more about the Feature Freeze deadline head on over to: https://wiki.linaro.org/Process/Cycle/FeatureFreeze Regards, Jamie. -- Linaro Release Manager [1] https://wiki.linaro.org/Releases/1105/Schedule

[PATCH v5 0/5] ARM: omap[34]: Thumb-2 compatibility fixes

by Dave Martin

This set of patches, along with some other patches under discussion on alkml, should enable omap3 and omap4 kernels to be built with CONFIG_THUMB2_KERNEL. This patch set builds on recent cleanup done by the omap maintainers. At least some of this code definitely works, most features have been tested successfully. Further testing, especially of Thumb-2 behaviour, is still welcome. Seems to work with CONFIG_SMP_ON_UP and CONFIG_THUMB2_KERNEL enabled on Beagle xM A2 and Panda A1. Thanks also to Santosh Shilimkar and Kevin Hilman for their help with testing. v3: * make SMC instruction syntax more consistent * remove do_wfi() in favour of the generic wfi() macro v4: * revert to the OMAP-specific do_wfi() implementation, pending discussion of how generic macros can/should be provided v5: * use ARM for low-level code in mach-omap2/*34xx.S, for correct interoperation with non-Thumb-capable firmware. I've stripped the Acked/Tested-bys from the major patches to mach-omap2/*34xx.S, since the reversion to ARM constitutes a significant change -- I would be grateful if people could re- test / re-review if they have the chance. For best future compatibility, I've left the changes which avoid architecturally deprecated features. Details below. Cheers, Dave The patches can be found, along with a buildable working tree, in the following repo: git://git.linaro.org/people/dmart/linux-2.6-arm.git * arm/omap-thumb2: has the patches proposed here * arm/omap-thumb2+merged: additionally has some patches cherry- picked from other trees which are needed in order for the patches on arm/omap-thumb2 to work usefully. * dirty/arm/omap-thumb2+merged: buildable test tree, which adds 2 local patches to work around a toolchain bug. A working kernel config for this tree is here: http://people.linaro.org/~dmart/arm_omap-thumb2+v2_config : CONFIG_SMP_ON_UP=y CONFIG_THUMB2_KERNEL=y CONFIG_SERIAL_OMAP=y (to avoid garbage on xM; for Panda use console=ttyS2) (The config is derived from the linaro omap config and so turns on loads of modules -- don't feel you have to build them all...) Cherry-picked patches originated from Russell's devel tree and Tony Lindgren's omap-testing tree: http://ftp.arm.linux.org.uk/pub/linux/arm/kernel/git-cur/linux-2.6-arm.git devel git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git omap-testing This series also depends on one un-merged patch to generic-ise the wfi() macro: git://git.linaro.org/people/dmart/linux-2.6-arm.git arm/wfi-macro Dave Martin (5): ARM: omap4: Provide do_wfi() for Thumb-2 ARM: omap4: Convert END() to ENDPROC() for correct linkage with CONFIG_THUMB2_KERNEL ARM: omap3: Remove hand-encoded SMC instructions ARM: omap3: Thumb-2 compatibility for sram34xx.S ARM: omap3: Thumb-2 compatibility for sleep34xx.S arch/arm/mach-omap2/include/mach/omap4-common.h | 4 ++ arch/arm/mach-omap2/omap-headsmp.S | 2 +- arch/arm/mach-omap2/omap44xx-smc.S | 8 ++-- arch/arm/mach-omap2/sleep34xx.S | 62 ++++++++++++++++++---- arch/arm/mach-omap2/sram34xx.S | 36 ++++++++++--- 5 files changed, 87 insertions(+), 25 deletions(-)

This sounds like a lot of upfront work indeed, to make KMS more generic, though I think a number of driver would benefit from it eventually. It could be something for the Linaro graphics working group to look at in the following 11.11 release, depending on how many other people are interested in getting there. Arnd

Nice tool: chdist

by Michael Hope

Hi everyone. Loic pointed me at 'chdist', a nice tool that makes working with different releases much easier. You can use it to poke into and download packages from different releases without setting up a chroot for each one. I use from my Maverick host to grab the source packages from Natty when trying to track down a bug. For example, I'm looking into adding cortex-strings into the Natty libc6. Tell chdist about Natty by running: chdist create natty Update the list of packages using: chdist apt-get natty update Check which version is currently uploaded: chdist apt-cache natty show libc6 Grab the source: chdist apt-get natty source libc6 The distributions and configuration files end up under ~/.chdist such as ~/.chdist/natty/etc/apt/. -- Michael
