[Linaro Connect] Session about packaging Linaro components

by Marcin Juszkiewicz

Hi all. During Linaro Connect there will be a session [1] about packaging tools and other components produced by Linaro teams. Goals: - Review the current set of components/projects create and maintained by Linaro - Identify the ones that are not yet part of Ubuntu and Ubuntu LEB - Discuss how to make the Linaro changes upstream at the distro-level as soon they are updated I want to get Linaro to the point where most of our tools will be available in Debian and Ubuntu distributions instead of random set of PPAs. Whom I would like to see there? Everyone who has written any packaged (or not yet) tool useful for other developers. Nevermind is it host or target, native or cross tool. 1. http://summit.linaro.org/lcq2-12/meeting/20859/review-the-missing-packages-…

Optimized kernel memcpy/memset

by Christian Robottom Reis

Hey there, I was asked today in the board meeting about the use of NEON routines in the kernel; I said we had looked into this but hadn't done it because a) it wasn't conclusively better and b) if better, it would need to be done conditionally per-platform. But I wanted to double-check that's actually true (and I'm copying Vijay to keep me honest). I have some references: http://lists.linaro.org/pipermail/linaro-toolchain/2011-January/000722.html http://groups.google.com/group/beagleboard/browse_thread/thread/12c7bd415fb… http://www.spinics.net/lists/arm-kernel/msg106503.html http://dev.gentoo.org/~armin76/arm/memcpy-neon_result.txt https://wiki.linaro.org/WorkingGroups/ToolChain/Benchmarks/InitialMemcpy?hi… https://wiki.linaro.org/WorkingGroups/ToolChain/StringRoutines?highlight=%2… Incidentally, this ties into the question sent earlier this week which had to do with Nico's work item in: https://blueprints.launchpad.net/linux-linaro/+spec/other-kernel-thumb2 Which IIRC Nico says probably isn't worth it, right? -- Christian Robottom Reis | [+55] 16 9112 6430 | http://launchpad.net/~kiko Linaro Engineering VP | [ +1] 612 216 4935 | http://async.com.br/~kiko

[ANNOUNCE] New boot loader on Snowball

by Mathieu Poirier

All, In our ongoing effort to move to an upstream-supported code base and booting the snowball with a device tree (DT) I have change the boot loader in the following android builds [1][2][3] to u-boot-linaro-stable [4]. Once the linaro-uboot is installed in a system it won't be able to boot images that were created at an earlier time. Say that build #500 has the new linaro-uboot and the image has been installed on the emmc. Once powered this uboot will not be able to boot build #499 that is installed on the mmc. To fix the problem, simply install build #500 on the mmc. This is because the mmc commands in the IK-uboot and the linaro-uboot differ. To install the linaro-uboot you *must* use the latest android-linaro-media-create found here [5] until the changes get merged in the official repository [6]. Something like: $ bzr branch lp:~mathieu.poirier/linaro-image-tools/linaro-image-tools Last but not least, the linaro-uboot is currently not able to save the environment variable block to the emmc card. That work is ongoing and the functionality expected to be part of 12.05. Find me on IRC if you have any questions. Regards, Mathieu.

can I read Overo's madc registers...??

by Sudhangathan B S

I did a number of searches and found that in the recent kernels the twl4030-madc module has been made upstream. And I found this link: http://wiki.gumstix.org/index.php?title=ADC_overo_2.6.39%2B as I followed it, I couldn't find the directories mentioned therein.. The most relevant thing I found in Linaro-Alip/Nano file system was the /sys/class/i2c-adapter/ folder. Now i'm into the wild and searching for the file I need, so that I can read the ADC values. Any help meanwhile....??? --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 --------------------------------- terms: twl4030-madc tps65950 hwmon madc driver sys class i2c-adapter

[PATCH 0/2] ARM: DAVINCI: cpuidle - cleanups

by Daniel Lezcano

These couple of patches use the new cpuidle core api to refactor some part of the code. The first one removes the state count initialization as it is done from the cpuidle core and the second one use the new API and removes the ops. The patchset is based on Lenb's tree on top of Robert Lee cpuidle consolidation work. I don't have this board, I was not able to test these patches.

[PATCH 0/3] OMAP: control: bootaddr and bootmod APIs

by Omar Ramirez Luna

Recently a patch went in for tidspbridge code, to ioremap SCM registers and solve a build break[1]. However it has been pointed out before that this is a layer violation given that control module should handle its own registers, this series is an attempt to create APIs for the users of these registers. With some adaptations this patch might also make use of it: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg66491.html Patch: staging: tidspbridge: use scm functions to set boot address and mode, will be sent separately to staging tree.

[PATCH v4 0/7] cleanup imx5 idle, add imx5/6 cpuidle

by Robert Lee

Cleanup up imx5 idle code and enable imx5 low powe idle for imx53. Add common imx cpuidle initialization functionality and add a i.MX5 and i.MX6Q platform cpuidle implementation. Based on v3.4-rc7 plus recently submitted/accepted MACHINE_INIT late_initcall patch: http://www.spinics.net/lists/arm-kernel/msg171620.html v4 changes: * Added several imx5 idle cleanups to series. * Modified imx_io_p2v function to allow common imx5 AIPS2 bus virutal address * Added comment to tzic_wakeup_enable(). * Movied imx5 idle code from mm-imx5.c to pm-imx5.c. * Removed unnecessary time consuming code execution that ran on each idle instance. * modified imx5_pm_init to be a late_initcall * added late_initcall to all imx53 MACHINE_START entries. * enabled imx5 low power idle for imx53 * rebased cpuidle driver on top of imx5 cleanup changes. * modified cpuidle driver exit time to reflect removal of unnecessary code v3 changes: * removed file introduced in v1 no longer needed after v2 [per Shawn Guo] * re-ordered added #includes in alphabetical order [per Shawn Guo] * Remove if(!drv) check to allow handling by stack trace [per Sascha Hauer] * Added missing return value in error meesage [per Shawn Guo] * fixed (void *) casting problem pointed out Sasha Hauer. Used a different type of casting to properly give warning on improper casting: arm_pm_idle = (void (*)(void))imx5_idle; Used this casting instead of adding a dummy caller function because adding the dummy function appears to unnecessarily introduce the following additional operations: static void imx5_pm_idle(void) { a0: e1a0c00d mov ip, sp a4: e92dd800 push {fp, ip, lr, pc} a8: e24cb004 sub fp, ip, #4 imx5_idle(); ac: ebffffd3 bl 0 <imx5_idle> } b0: e89da800 ldm sp, {fp, sp, pc} http://permalink.gmane.org/gmane.linux.linaro.devel/11653 v2 changes: * Removed some unnecessary spaces [per Jess Juhl] * Added return value for an error message [per Sascha Hauer] * Reworked init scheme to use device tree late_initcall [per Sascha and Shawn] * Moved imx6q and imx5 cpuidle functionality to existing files. https://lkml.org/lkml/2012/5/1/363 v1 initial submission: https://lkml.org/lkml/2012/4/16/644 Robert Lee (7): ARM: imx: Modify IMX_IO_P2V macro ARM: imx: Add comments to tzic_enable_waker() ARM: imx: clean and consolidate imx5 suspend and idle code ARM: imx: Enable imx53 low power idle ARM: imx: Add common imx cpuidle init functionality.

New Gator version ready for Linaro kernels

by Jon Medhurst (Tixy)

Hello All ARM have released a new version of Developer Studio 5 (DS-5) and we now have a new version of the Gator component [1] to go with this which needs updating in all Linaro kernel trees that will be part of the 12.05 release. For those people maintaining kernel trees here is what this means... - If your kernels are including the linux-linaro-core-tracking [2] branch then you will get the new Gator version from this when it is updated over the next couple of days. You don't need to do anything except to make sure you are up to date with this branch before the 12.05 release. - For Ubuntu kernels not including linux-linaro-core-tracking (and not being released from the common linux-linaro branch) then you should replace your existing gator topic branch (or add one if it is missing). This new topic branch can be created by pulling from the ARM Landing Team's tree [3], we have tree topic branches available for the last three kernel versions... tracking-armlt-gator (3.4-rc7) 3.3-armlt-gator-5.10 3.2-armlt-gator-5.10 The code in these branches is identical, they are just rebased onto different Linux versions to make pulling easier. - For Android kernels, if your kernel already includes the Gator topic, then this should be updated as above. If it doesn't already have Gator then you can add this topic now, or, leave it for the time being. (Some Android builds are using a separate Gator git repo in their manifest and this will continue to work for now.) If anyone has any questions or if anything is unclear, please do hesitate to contact me. For those people who have applied Mali driver patches to support profiling by Gator: you don't need to modify those Mali patches, just take the new version of Gator, this will still work OK. Cheers -- Tixy [1] Gator is the ARM target device components for ARM's Streamline Performance Analyzer which is part of their Developer Studio (DS-5). http://www.arm.com/products/tools/software-tools/ds-5/streamline.php [2] http://git.linaro.org/gitweb?p=kernel/linux-linaro-tracking.git;a=shortlog;… [3] git://git.linaro.org/landing-teams/working/arm/kernel.git
