[PATCH 0/3] vmevent: Some fixes + a new event type

by Anton Vorontsov

Hi all, This small patch set fixes a bug in the vmevent core, plus makes the vmevent-test buildable w/o unneded SDL library. Plus, we add a new 'cross' event type: the event will trigger whenever a value crosses a user-specified threshold. It works two-way, i.e. when a value crosses the threshold from a lesser values side to a greater values side, and vice versa. We use the event type in an userspace low-memory killer: we get a notification when memory becomes low, so we start freeing memory by killing unneeded processes, and we get notification when memory hits the threshold from another side, so we know that we freed enough of memory. The patches are against git://github.com/penberg/linux.git vmevent/core Thanks! -- Anton Vorontsov Email: cbouatmailru(a)gmail.com

[ACTIVITY](John Stultz) Apr 2-6

by John Stultz

=== Highlights === * Did some extra testing and found a few bugs in the volatile range code. Fixed those up and sent it out to lkml. * Finished a second pass at rebasing the AOSP 3.3 tree to 3.4-rc1. Needs testing then I will send to Andrey. * Handled some community clocksource issues around long irqoff periods * Quite a bit of discussion on linaro-dev about the config fragment tree and what the workflow should be with it. * Merged a bunch of config fragment patches from Tixy and Tushar * Got pulled into internal customer support issue. * Wrote up a rypple review * Wrote up talk proposal for plumbers * Reviewed Anton's ulmkd draft mail * Did weekly Android subteam mail === Plans === * Hit some ackward issues w/ the fadvise volatile work. Need to read some more VM code and maybe ask for some help from VM friends. * Do some testing w/ my 3.4-rc1 based android patch set & send out. * Read up on sysrq-t and why its holding irqs off for very long periods of time. === Issues === * NA.

by Dong Aisheng

=== Pinctrl === * Reviewed pinctrl core dt binding patches Merged into pinctrl subsystem by Linus Walleij. * sent mx28 basic dt support patch.(Merged by Shawn) * add dt support for pinctrl-imx driver based on common dt binding. The mux part was done. The config and gpio part were still ongoing. * sent two pinctrl core fix patches. === Plan === * complete pinctrl-imx driver based on dt in next week including config and gpio support.

[ACTIVITY] (Rajendra Nayak) Apr 02 - Apr 06

by Rajendra Nayak

== Rajendra Nayak <rnayak> == === Highlights === * Worked mostly on OMAP2/3 common clk data generation using python. Thanks to Paul Walmsley who did a perl script to convert C99 structs to JSON format, which allowed me to use python to reconvert from JSON to the common clock format. Fixed some issues around OMAP4 common clk scripts. * Working on a series to get rid of the clk->clkdm association for OMAP2/3. This greatly helps reduce the data size of OMAP2/3/4 clock data when converting to common clk. === Plans === * Continue on pending issues with the script to generate OMAP2/3 common clk data. * more work on getting rid of clk->clkdm association. === Misc === * Will be off 2 days next week. April 9th and April 10th.

linux-linaro on IMX53QSB

by Eric Bénard

Hi Eric, while testing the Quick Start Board, I quickly tried several kernel built from git://git.linaro.org/bsp/freescale/linux-linaro.git - lt-3.2-imx5 : needs some fixes to build, boots but X fails to run (with 11.09.01 BSP's userland on the VGA output) - lt-3.2-imx6: needs some fixes to build, fails to boot - lt-3.1-2011.12: don't remember the result - rel_imx_2.6.38_12.01.01 : fails to boot I can provide log & more details for each configuration later if needed. The instructions on the Wiki ( https://wiki.linaro.org/Boards/MX53QuickStart ) seems outdated. Is this platform still supported by Linaro ? What is the Freescale Landing team's recommended tag to use to test linux-linaro on iMX53QSB ? What are the recommended GPU & VPU libraries to use to get the best of the i.MX53 with linux-linaro ? Thanks Eric -- http://eukrea.com/en/news/104-2012

== Omar Ramirez <omarrmz> == === Highlights === * Working on v2 of the agitator, so far: - Cleanup comments and minor bugs. - Print of execution time on exit, also triggered when catching SIGINT and SIGTERM. - Added independent cpu switching along with synchronous switching (for all cpus). - Added random switching, option to specify seed and the limit to randomize the time intervals. * Sent omap iommu fix for scenario: domain destroy with devices attached. === Planned === * debugfs interface for big.LITTLE to know which cluster is being used. * Add independent thread switching to the agitator.

[ACTIVITY] (Shawn Guo) Week of Mar 26

by Shawn Guo

=== Highlights === * Sent a series to clean up basic clks of common clk framework, and Mike will integrate them into his fixup branch. * Sent a patch to fix the issue that audio driver only works with SSI1 on imx5. It assigns dma peripheral type according to bus topology. (Merged by Mark) * Sent a couple of patches to fix sgtl5000 MIC Bias power and add audio routing support for imx-sgtl5000 machine driver to get capture functional. (Merged by Mark) * Tested patch "ASoC: sgtl5000: Convert mic bias to a supply widget" from Mark with imx-sgtl5000. * Added basic clock management for fsl_ssi driver. To make it compile for both powerpc and imx, the powerpc dummy clock API needs to be built in. Sent a patch to linuxppc-dev list and waiting for comment. * Reviewed and merged anatop-regulator imx6q dts patch from Paul. * Reviewed and merged basic imx28 DT patch (booting into console with nfsroot) from Aisheng. * Tested v3.4-rc1 on imx28 and imx6q, and sent a couple patches to fix amba probe failure, section mismatch warning. -- Regards, Shawn
