RFC: Initial Power and Voltage domain support for powerdebug

by eric van tassell

+ all written in usermode + no new proc files + configuration based on text file so easy to adapt to the non-omap proletarians + gui alignment still needs work + sample config files for PD and VDD in the patch but lots of registers and domains still need to be added + same code does power and voltage domains + diff attached + screenshots attached -- - evt (Eric van Tassell) twitter: evt_texelsoft linked-in: linkedin.com/in/evttxl

[PATCH] perf report: fix event name reporting

by Dmitry Antipov

Use trace_find_event to find event name before looking through /sys files. This helps 'perf report' to show real event names instead of 'unknown:unknown' when processing perf.data recorded on another machine.

Linaro rootfs / kernel version combination

by Suresh Kumar SHUKLA

Hi all, I need some help in choosing right version of rootfs for my environment. I have a development board with ST SoC with Cortex-A9 dual core and VFPv3-D16. Kernel version available to me is 2.6.37. I am using Debian 6 arm-hf port, but would like to try Linaro rootfs. 1. What is the version of linaro filesytem I should pick (optimum for -mfpu=vfp and -mfloat-abi=hard) ? 2. I don't have a hwpack, is it possible to use vexpress or similar rootfs. Regards, Suresh

Git repo for kernel config fragments created

by Jon Medhurst (Tixy)

I have created an git repo for the kernel config fragments we produced a while ago, this is at git://git.linaro.org/kernel/configs.git The config-core-tracking branch in this repo is intended to be added to the linux-linaro-core-tracking branch and so be available in all Linaro kernels. This currently provides three config fragment files: linaro/configs/linaro-base.conf Config options common to all Linaro kernels linaro/configs/ubuntu.conf Config options for all Ubuntu kernels linaro/configs/android.conf Config options for all Android kernels In addition to these, a board specific config fragment is required to produce a final kernel config. This may be made available by a Landing Team's kernel tree (I have done this for vexpress [1]) or; for experimental purposes, or to support legacy platforms, I have a separate config-boards-tracking branch of the new configs.git. (Currently this contains the Origen and iMX5 fragments produced a while ago.) To create an Ubuntu kernel config from these fragments for a device called $BOARD, you need to run a command like: ARCH=arm scripts/kconfig/merge_config.sh \ linaro/configs/linaro-base.conf linaro/configs/ubuntu.conf \ linaro/configs/$BOARD.conf For Android, s/ubuntu/android/ in the above. At some point soonish, I hope to come up with a mechanism whereby Android builds have the option to dynamically generate their kernel config as above. John Rigby is planning on adding a similar option to the Ubuntu packaging jobs. Hopefully this work will enable: - easier management of system wide config settings required by working group output or Linaro policy - place board specific configuration in the hands of the people maintaining that boards kernel - more consistent kernel builds, so teams can test in the same environment as Linaro's final releases I intend to maintain git://git.linaro.org/kernel/configs.git and will keep separate non 'tracking' branches for older kernel versions (I currently have branches for 3.4). -- Tixy [1] http://git.linaro.org/gitweb?p=landing-teams/working/arm/kernel.git;a=short…

android-3.4 or android-3.4-compat

by John Stultz

Hey Andrey, Zach, So I'm back from my vacation, and have found that the Android team has released a -compat tree for their 3.4 kernel. Basically this tree re-adds some items like earlysuspend and classic wakelocks in order to provide better compatibility with old (and by old, I really mean current as far as we see - so ICS and earlier) Android userland. Since we're still shipping ICS, and have no access to whatever the Android 5.0 userland will be, it seems merging in the -compat tree would make sense. However, I know Tixy and others have already tried to address the lack of earlysuspend in the android-3.3+ kernels, so I wanted to double check that this wouldn't cause additional pain (since those adjustments might need to be reverted). So I just wanted to check first with folks to make sure there are no objections to merging in the -compat changes, and that the timing of merging in these changes isn't problematic (I can happily hold off till this months release is done, so we don't risk any last minute gotchas). thanks -john

12.05 linux-linaro kernel tree

by Andrey Konovalov

Greetings, So far I wasn't updating the linux-linaro tree since the 12.04 release. (The generic topic updates were being done to the linux-linaro-core-tracking tree) Now it is time to move the focus to the linux-linaro tree. For one week it will use the mainline tip as the base. Then, on next Thursday the most recent -rc will be selected as the base, and won't be changed until 12.05 is released. Most probably it will be v3.4-rc7. The 12.05 linux-linaro tree will get the ARM and Samsung LTs topics plus the 7 generic topics currently included into the linux-linaro-core-tracking tree: ufs (ufs-for-linux-linaro) emmc (emmc-for-linux-linaro) thermal_exynos4_imx6 (thermal_exynos4_imx6_work) linaro-android-3.4 armlt-gator (tracking-armlt-gator) umm-wip (umm-3.4rc4-wip) linaro-configs-3.4 If you don't see your generic topic in this list, but you think it should be there, please let me know ASAP. If you have a new topic to add, please send me the request before the next Thursday, May 17; the sooner, the better. The requirements for a topic can be found here: https://wiki.linaro.org/Platform/DevPlatform/LinuxLinaroKernelTreeProcess#A… The landing teams - please update your topic branches if needed: ARM: tracking-armlt-hdlcd tracking-armlt-mmc tracking-armlt-arm-arch-fixes tracking-armlt-misc-fixes tracking-armlt-ubuntu-config tracking-armlt-android-config Samsung: topic/base topic/core topic/bl topic/dt topic/fb topic/pd topic/s2ram topic/asv_cpufreq topic/led topic/dummy_reg topic/gadget topic/touch topic/wlan topic/audio topic/hdmi topic/mali topic/cma_v24 topic/android_config Thanks, Andrey

Are we going to start using config fragments?

by Jon Medhurst (Tixy)

Are we going to start using the config fragments we created a while ago? (Or did we not reach consensus on that?) If we could get them into a 'final' git location and start using them for Ubuntu packaging, I can arrange for a mechanism to enable Android builds to use them. I have attached a couple of patches for the config fragments (3.5 removed the PERF_COUNTERS config). -- Tixy
