Hi all, In the scope of my work on systemtap, I would like to have a look to its user-space instrumentation capabilities. Systemtap relies on uprobes+utrace for that purpose so has anyone some feedback/global view on these with regards to ARM ? utrace did not make it into the mainline and would need more to convince Linux. I have also seen that a utraceless uprobe is emerging. There is also a PPA with a utrace enabled kernel but this is not covering ARM. I am in parallel seeking info on utrace-devel mailing list. thanks for any help Regards Fred

ION: google's answer to GEM?

by Clark, Rob

hmm, https://review.source.android.com/#change,22239 >From a quick look, it appears to be doing a similar thing as GEM.. although as a stand-alone driver rather than coupled with display driver (drm). BR, -R

[NOTES] Minutes & Actions: Kernel Working Group meetings of April 11, 2011

by Mounir Bsaibes

Enclosed you'll find a link to the agenda, minutes, actions and IRC logs from the Linaro kernel working group weekly meetings of April 11, 2011. https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Meetings/2011-04-… == Summary == * ARM Programmer's guide * ARM is sharing with us an early version of a book on ARM architecture * Needs feedback back to ARM from Linaro as an expert group on ARM and opensource * Send feedback to David Rusling and/or to Loic * Validation: what the KWG would need in terms of validation for next cycle * Support for the desired monthly release. For instance, automated builds & automated boot * Automated builds and tests for tree merges. * Wider testing than an individual can do by the validation group will be helpful * It would be very helpful if the test suite and boards were available to anyone to test code changes * TSC was OK with refusal to rewrite the smc driver. * TR's for next cycle, seem we have more than we can handle in 6 months * Unlikely to get to the low priority items and medium items are at risk * Discussion about bug 664477, need more info how to reproduce it and owner to handle and/or submit it upstream Regards, Mounir

Libraries with NEON backends

by Michael Hope

Hi there. I'm looking for areas where the toolchain could generate faster code, and a good way of doing that is seeing how compiled code does against the best hand-written code. I know of skia, ffmpeg, pixman, Orc, and efl - what others are out there? Thanks for any input, -- Michael

[PATCH] ARM: EXYNOS4: Fix card insert/removal event detection on smdkv310 board

by Thomas Abraham

On SMDKV310 board, a card detect gpio pin is available that is directly connected to the io pad of the sdhci controller. Fix incorrect value of cd_type field in platform data for sdhci instance 0 and 2.

[PATCH] ARM: EXYNOS4: Fix incorrect mapping of gpio pull-up macro to register setting

by Thomas Abraham

The S3C_GPIO_PULL_UP macro value incorrectly maps to a reserved setting of GPIO pull up/down registers on Exynos4 platform. Fix this incorrect mapping by adding wrappers to the s3c_gpio_setpull_updown and s3c_gpio_getpull_updown functions.

Notes & Actions: Linaro Graphics Working Group - Apr 06, 2011

by Alexandros Frantzis

Hi, notes and actions from our Wednesday graphics working group call are available on the wiki: + https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Notes/2011-04-06 Details about when and where of this meeting can be found here: + https://wiki.linaro.org/WorkingGroups/Middleware/Graphics#Weekly%20Public%2… Summary ======= * Started porting two example programs (cairogears and cairo-clock) to cairo-gles2. * Benchmarks * Test definitions * Created out-of-tree abrek test definitions branch (+packaging) for WG for glcompbench, cairo-traces and qt-traces and added them to linaro-graphics-wg-tests. * Had a meeting with infrastructure/platform team to align benchmarking needs. * glcompbench : Finished profiler branch and pushed to trunk (lp:glcompbench) * Skia * segfault happens in arm_memset32() for Tegra2 as well as EfikaMX if ARM_HAVE_NEON not enabled, bug created in skia upstream * Need account in git.linaro.org for creating skia branch * Kwin : kdelibs and kde-workspace mainline packages available in Kunal's PPA https://launchpad.net/~goelkunal/+archive/multimedia, but ARM build still not available * DRI/Mali * Investigated overall KMS architecture and functionality and need to investigate the recent source which allows KMS to allocate a buffer without using DRM. * Added support in glewinfo file to verify the entry point of the ES and EGL extensions supported. * Compiz * Updated build system to disable building non-ported plugins and went through all core plugins and verified they work correctly. * Tested on efikamx, needs some changes for improper GL_BGRA support then doesn't draw correctly. Thanks, -- - Alexandros
