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.

Release critical and important bugs

by Jamie Bennett

Hi, As we near final release it is even more important that bugs which effect the LEB's and other images are caught early and fixed as soon as possible. To help aid the Linaro Release Team [1] in identifying and dealing with these types of bugs the following procedure significantly helps on projects which produce, or are installed on the images: 1) All bugs in a 'New' state should be sufficiently triaged to determine their 'Importance'. 2) All bugs which are deemed 'High' or 'Critical' should be highlighted to the Release Team. To do this use the 'Subscribe someone else' link on the right hand side of the bug. When the pop-up appears type 'linaro-release' into the box and select the release team when it is found. 3) If the bug needs discussion please add it to the wiki page for the current weeks Release meeting. The calendar for the Release meeting can be found at: https://wiki.linaro.org/Cycles/WeeklyReleaseMeeting Meetings are currently on a Thursday so add the bug to the 'Bugs' section of the next meeting. If possible please attend the meeting. The Release Team will go through the list of bugs [2] regularly and help to get fixes in place ready for milestone releases [3]. This information can also be found on the wiki at: https://wiki.linaro.org/Cycles/BugManagement Regards, Jamie. -- Linaro Release Manager | Platform Project Manager [1] https://launchpad.net/~linaro-release [2] https://bugs.launchpad.net/~linaro-release [3] https://wiki.linaro.org/Cycles/1105#Milestones
