All other components including QEMU and GLIBC are upstream. Binary toolchains: * Wrote up a specification, began discussion. * Looking into tools for doing the build and test. crosstool-ng looks decent. QEMU and A15: * Working on usermode support for the new A15 instructions. Will allow testing the A15 version of GCC when it comes out of ARM. * Discussed A15 system mode, split out into blueprints and cards GCC performance: * Keeping on. * Default NEON vector size is now quad word. Should show a nice speed up.

[PATCH 2/2 v7] pinmux: add a driver for the U300 pinmux

by Linus Walleij

From: Linus Walleij <linus.walleij(a)linaro.org> This adds a driver for the U300 pinmux portions of the system controller "SYSCON". It also serves as an example of how to use the pinmux subsystem. This driver also houses the platform data for the only supported platform. This deletes the old U300 driver in arch/arm/mach-u300 and replace it with a driver using the new subsystem. The new driver is considerably fatter than the old one, but it also registers all 467 pins of the system and adds the power and EMIF pin groups and corresponding functions. The idea is to use this driver as a a reference for other implementation so it needs to be as complete and verbose as possible. Signed-off-by: Linus Walleij <linus.walleij(a)linaro.org> --- ChangeLog v6->v7: - Adjust the driver to return the group list as an array of strings instead of a unsigned * array. - Add support for the EMIF0 and EMIF1 pin groups. - Acquire all muxmaps using pinmux hogs from the core using a subsystem_initcall(). This way we need not change any drivers or buses. We have the correct struct device * pointers anyway so why not do it from there, and it illustrates pretty well what the pinmux core will be able to do once it can access the device tree. - Use new convenience macros for system mappings. - Unregister the GPIO range at removal. --- arch/arm/mach-u300/Kconfig | 2 + arch/arm/mach-u300/Makefile | 2 +- arch/arm/mach-u300/core.c | 84 +++-

[PATCH 0/4] smdkv310 modifications

by Chander Kashyap

These patches does the following things: uses CONFIG_MACH_TYPE generic macro to initialize machine id. Uses get_ram_size () to initialize DRAM bank size to accurate value Migrates mmc spl support from mmc_spl framework to spl framework Replace hardcoded value with a macro and removes typedef in board/samsung/smdkv310/mmc_boot.c file.

[ANNOUNCE] android-tools-(adb,fastboot}

by Tom Gall

The development platforms team would like to announce the availability of the android-tools-adb and android-tools-fastboot packages. This allows one to have access to these tools without having to go through all the steps involved with the AndroidSDK and can be useful especially in situations where you just need the one or two tools. The packages should be considered experimental. We are undecided if these packages will be maintained long term as after all one can just install the Android SDK. Feedback both positive or negative will greatly help influence this decision. The tools are found in ppa:linaro-maintainers/tools. -- Regards, Tom "We want great men who, when fortune frowns will not be discouraged." - Colonel Henry Knox Linaro.org │ Open source software for ARM SoCs w) tom.gall att linaro.org w) tom_gall att vnet.ibm.com h) tom_gall att mac.com

[ACTIVITY] Multimedia WG status report - wk38.2011 (20110919-20110923)

by Ilias Biris

Status: https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyReport Last meeting minutes: https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Notes/2011-09-20 == Highlights: == * Components released, only thing missing is test-content - that project required a special check with the TSC so that we are given the green light to distribute content which is Creative Commons licensed. Checking with the TSC has started - ongoing. * Team has started planning the content for 11.10 release. * For Connect: NEON optimization forum: organized a couple of presentations for LCQ4.11 - one of which will be "best practices" * Requirements for the next quarter - list of what is being considered is as follows (Items without a link in papyrs need still to be described and justified) - UMM Camera Demo - https://linaro.papyrs.com/page/4156/MMWG2011-1/# - UCM for Android - https://linaro.papyrs.com/page/4157/MMWG2011-2/# - libpng optimization - Better video rendering integration in UI, like X11 proposal for wayland, extended dri2 - Audio DTS decoding - could be tricky, involves legal aspects which need to be carefully looked at, already done in libav? - Compressed data sound support (as in http://www.linuxplumbersconf.org/2011/ocw/proposals/633) - Realvideo on ARM (popular in China) - needs optimization for 720p playback, VGA is ok - armv6 optimizations for vp8 in libav - 10-bit h264 optimization needed in libav - 3D video stream - secure streaming (like netflix) - audio library optimization Best, -- Ilias Biris ilias.biris(a)linaro.org Project Manager, Linaro M: +358504839608, IRC: ibiris Skype: ilias_biris Linaro.org│ Open source software for ARM SoCs

cpu hotplug test scenarii

Any feedback would be appreciate Thanks a lot -- Daniel Test 1: check the sysfs files are present ========================================= for each cpu * check /sys/devices/system/cpu/cpuX/online is there What about the particular case for cpu0 where the 'online' file is there but shouldn't as the other arch ? Test 2: check cpu state is reflected in sysfs ============================================= for each cpu * set cpuX offline * check cpuX status is offline * set cpuX back online * check cpuX status is online Test 3: check the affinity does not work on an online cpu ========================================================= for each cpu * set cpuX offline * check 'taskset -c X /bin/true' fails * set cpuX back online Test 4: check cpus are reflected on /proc/cpuinfo correctly =========================================================== NRCPUS=<number of configured cpu on the system> for each cpu * set cpuX offline * check /proc/cpuinfo 'processor' keyword count is 'NRCPUS - 1' * check the processor keyword contains a cpu id different from the cpu we offlined * set cpuX back online Test 5: test userspace notification =================================== for each cpu * set cpuX offline * check from userspace notification has been done with the command 'udevadm monitor --kernel --subsystem-match=cpu' * and the event is related to the cpuX and 'offline' * set the cpu online * check from userspace notification has been done with the command 'udevadm monitor --kernel --subsystem-match=cpu' * and the event is related to the cpuX and 'online' Test 6: do some stress test =========================== for each cpu * for i in 1 .. 50 * set cpuX offline * set cpuX back online - -- <http://www.linaro.org/> Linaro.org │ Open source software for ARM SoCs Follow Linaro: <http://www.facebook.com/pages/Linaro> Facebook | <http://twitter.com/#!/linaroorg> Twitter | <http://www.linaro.org/linaro-blog/> Blog -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOgvR5AAoJEAKBbMCpUGYAd+cH/Al3bFhii/cgUqUxD9tWohoi +J7vfcbWbeDfX8cpYSzYczThfO97TYgGQdMjRkcq3MUkQ0xy/wWw96mZFl87L0eq 5bYnOgnZa/glUUeENyPs8/hrSJ2Mhf/Kcnp8VLK53E9OrzQ6bYOs7ms1ap81gsvW Ub9UL4Zzq0YkPMP1T0M63tt3qioukNlUDPV2ZNTAg0iTHy7tXuaWp6bx8bk+ggXA wqs+XCridjzD5YjZcvKyn0f5nSlGDx1rH+rOEGSktudZInvJBsyCmOMa3upWMJUf loBqhK4LqrYwIU/JbCTQaB9F1U1yYioqvgZBlO/LuOR/nbLmJFXtfeQOLbA9lRk= =Jrc3 -----END PGP SIGNATURE-----
