Muti touch device android failed to recognise

by dani maoz

Hi I have created a virtual multi touch virtual driver, I see that Event hub Detect the device but when i transmit events , no movement occurred on the screen (No X or Y changed) I tried to use protocol A pr Protocol B same result. why the events not transmitted to framework Any Idea See below the logs (Pandaboard Linaro 4.1.2) EventHub /EventHub( 1775): New device: id=7, fd=195, path='/dev/input/event3', name='test_mt_touch', classes=0x14, configuration='', keyLayout='', keyCharacterMap='', builtinKeyboard=false, usingSuspendBlockIoctl=false, usingClockIoctl=false I/InputReader( 1775): Device reconfigured: id=7, name='test_mt_touch', size 1280x720, orientation 0, mode 3, display id 0 I/InputReader( 1775): Device added: id=7, name='test_mt_touch', sources=0x00002002 Event transmitted from driver using getevent -lt /dev/input/event3 [ 3859.719026] EV_ABS ABS_MT_POSITION_X 000000c8 [ 3859.719056] EV_ABS ABS_MT_POSITION_Y 000000c8 [ 3859.719056] EV_ABS ABS_MT_WIDTH_MAJOR 0000002c [ 3859.719056] EV_ABS ABS_MT_TOUCH_MAJOR 00000000 [ 3859.719056] EV_SYN SYN_MT_REPORT 00000000 [ 3859.722932] EV_SYN SYN_REPORT 00000000 [ 3863.303383] EV_ABS ABS_MT_POSITION_X 000000c8 [ 3863.303383] EV_ABS ABS_MT_POSITION_Y 000000c8 [ 3863.303414] EV_ABS ABS_MT_WIDTH_MAJOR 0000002c [ 3863.303414] EV_ABS ABS_MT_TOUCH_MAJOR 00000028 [ 3863.303414] EV_SYN SYN_MT_REPORT 00000000 [ 3863.303475] EV_SYN SYN_REPORT 00000000

big.LITTLE MP status June 18, 2013

by Serge Broslavsky

https://wiki.linaro.org/projects/big.LITTLE.MP Work Items for functional completion: https://wiki.linaro.org/projects/big.LITTLE.MP/WorkItems Main Project page: https://launchpad.net/linaro-big-little-system Development ============ 1. big.LITTLE IKS IKS snapshot: git://git.linaro.org/landing-teams/working/arm/kernel.git More information: http://lists.linaro.org/pipermail/linaro-dev/2013-May/015882.html Also the latest Linaro 13.05 release contains big.LITTLE release with IKS code integrated. By default MP is used (IKS is off). To enable IKS: echo 1 > /sys/kernel/bL_switcher/active Same is planned for Linaro 12.06 release. 2. big.LITTLE MP There are two branches, which are functionally equivalent - they tweak the scheduler to select the right processes to move to the A15 and try to decrease power consumption while maintaining performance. * A Reference big.LITTLE MP patchset (based on ARM Beta patchset), merged with linux-linaro: https://git.linaro.org/gitweb?p=arm/big.LITTLE/mp.git;a=shortlog;h=refs/hea… Recommended to be used for testing. * And an upstream (work in progress) big.LITTLE MP patchset: https://git.linaro.org/gitweb?p=arm/big.LITTLE/mp.git;a=shortlog;h=refs/hea… Being worked on in order to achieve the performance/power numbers of the reference one. Upstream discussion is ongoing. * Documentation: Code flow is already covered by several LWN articles. See https://wiki.linaro.org/WorkingGroups/PowerManagement/Doc/ in the Articles section. We will provide a tuning guide once we have reached agreement upstream. * Automated benchmarking code is ready: - Golden Board is to be used for running daily tests. - Both branches - reference and upstream to be tested in the future. Blueprint Updates ------------------ * https://blueprints.launchpad.net/linaro-big-little-system/+spec/big-little-… Ongoing work. * https://blueprints.launchpad.net/linaro-big-little-system/+spec/small-task-… - Big variation previously seen is not visible on the Golden Board. It might be caused by an USB stick with insufficiently high speed - working on this hypothesis. - Latest patchset (not yet published upstream) shows low delta with the reference patch set results. * https://blueprints.launchpad.net/linaro-big-little-system/+spec/sched-coope… - Postponed.

gcc 4.7 in meta-linaro-toolchain

by Nicolas Dechesne

hi, in meta-linaro-toolchain (dylan branch), the recipe points to gcc-linaro-4.7 from 1304 release: https://git.linaro.org/gitweb?p=openembedded/meta-linaro.git;a=blob;f=meta-… However that file seems to have be removed/cleaned from where the recipe expects it: http://cbuild.validation.linaro.org/snapshots/ As such anyone build against that branch will now fails. That brings some questions: - How do we want to deal with that situation? Is ( http://snapshots.linaro.org/openembedded/sources) guaranteed to always keep all tarballs, forever? Or should we put such tarballs in such a place (and update recipes accordingly)? There can be non Linaro users of our layers (it's even referenced publicly here: http://layers.openembedded.org/layerindex/layer/meta-linaro-toolchain/) - most of the recent commits seem to go to master, not dylan. so it clearly stated somewhere what our official requirements/committments are wrt to OE branch support? thanks nicolas

[PATCH 0/7] uprobes: Add uprobes support to ARM

by David Long

This patch series adds basic uprobes support to ARM. It is based on patches developed earlier by Rabin Vincent. That approach of adding special cases into the kprobes instruction parsing code was not well received. This approach separates the ARM instruction parsing code in kprobes out into a separate set of functions which can be used by both kprobes and uprobes. Both kprobes and uprobes then provide their own semantic action tables to process the results of the parsing. Some regression bug fixing is still in progress on this, and some more definitions may be moved from kprobes*.h files into more generic include files. However, at this point feedback on the basic approach would be appreciated. These patches are based on v3.10-rc3 David A. Long (2): ARM: Separate kprobes instruction parsing into routines sharable with uprobes ARM: add uprobes support Rabin Vincent (5): uprobes: move function declarations out of arch uprobes: allow ignoring of probe hits uprobes: allow arch access to xol slot uprobes: allow arch-specific initialization uprobes: add arch write opcode hook arch/arm/Kconfig | 4 + arch/arm/include/asm/kprobes.h | 17 +- arch/arm/include/asm/probes.h | 23 ++ arch/arm/include/asm/ptrace.h | 6 + arch/arm/include/asm/thread_info.h | 5 +- arch/arm/include/asm/uprobes.h | 34 ++ arch/arm/kernel/Makefile | 3 +- arch/arm/kernel/kprobes-arm.c | 496 ++++++----------------------- arch/arm/kernel/kprobes-common.c | 260 +--------------- arch/arm/kernel/kprobes-thumb.c | 31 +- arch/arm/kernel/kprobes.c | 7 +- arch/arm/kernel/kprobes.h | 51 +-- arch/arm/kernel/probes-arm.h | 67 ++++ arch/arm/kernel/probes.c | 624 +++++++++++++++++++++++++++++++++++++ arch/arm/kernel/signal.c | 4 + arch/arm/kernel/uprobes-arm.c | 221 +++++++++++++ arch/arm/kernel/uprobes.c | 203 ++++++++++++ arch/arm/kernel/uprobes.h | 25 ++ arch/powerpc/include/asm/uprobes.h | 1 - arch/x86/include/asm/uprobes.h | 7 - include/linux/uprobes.h | 17 + kernel/events/uprobes.c | 54 +++- 22 files changed, 1429 insertions(+), 731 deletions(-) create mode 100644 arch/arm/include/asm/probes.h create mode 100644 arch/arm/include/asm/uprobes.h create mode 100644 arch/arm/kernel/probes-arm.h create mode 100644 arch/arm/kernel/probes.c create mode 100644 arch/arm/kernel/uprobes-arm.c create mode 100644 arch/arm/kernel/uprobes.c create mode 100644 arch/arm/kernel/uprobes.h -- 1.8.1.2
