[PATCH V3] ARM: EXYNOS4: Add machine support for 7" LCD on ORIGEN

by Tushar Behera

ORIGEN board is fitted with 7" LCD panel HV070WSA. The pixel resolution of the LCD panel is 1024x600. Also power domain device for LCD0 is registered. Signed-off-by: Tushar Behera <tushar.behera(a)linaro.org> --- Changes for V3: * Added error check for gpio request in LCD power function Changes for V2: * Added power domain device registration for LCD0 The patch is rebased on [1]. For proper working of LCD on ORIGEN, following patches are needed. These patches are already submitted to the mailing list. a.

install alsa ucm configurations

by Feng Wei

Hi, I initiate an install script for ucm configurations. The basic idea is -- 1. Decide the destination directory (if not specified by arguments, detect it) 2. Decide target sound card (must be specified by argument, and only the target configurations will be installed) 3. After copying ucm configurations to destinations, initiate the alsa mixer to ucm default values The script is install.sh at http://git.linaro.org/gitweb?p=people/weifeng/alsa-ucm-conf.git. Please check and if there're more requirements for linaro 1109 release, please tell me. -- Wei.Feng (irc wei_feng) Linaro Multimedia Team Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog

[PATCH] ARM: EXYNOS4: Enable double linefill in PL310 Prefetch Control Register

by Siarhei Siamashka

Setting "Double linefill enable" bit improves memcpy performance from ~750 MB/s to ~1150 MB/s when working with large buffers and also the performance of just anything which may need good memory bandwidth (for example, software rendered graphics). Additionally setting "Double linefill on WRAP read disable" bit compensates most of the random access latency increase.

[ACTIVITY] Graphics WG status report - wk36.2011 (20110905-20110909)

by Ilias Biris

Status in more detail: https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/WeeklyReport Wk36 meeting minutes: https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Notes/2011-09-07 == Highlights == Release-wise the work is getting along fine. Headlines and Acceptance criteria updated to nearly all blueprints for 1109 In particular: - Unity/Nux/Compiz: work is ongoing based on the discussion we have had to deliver code to Oneiric, working together with the Ubuntu side and upstream (compiz and nux maintainers are also handling the Ubuntu branches for Oneiric) - the work has been testing the maintainer's nux branch, merging our gles branch with oneiric compiz branch, and working on getting unity using nux framebuffer object - glmark2 - Android team integrated glmark2 into panda-leb daily builds (assisted with some issues). Finished and merged desktop effects (blur) benchmark. Bug https://bugs.launchpad.net/glmark2/+bug/850116 reported, seems to not be a glmark2 issue at least based on the investigation till now. - GLcompbench: reviewed pending merges, work progressing well there, and changed glcompbench to use glproxy instead of directly linking with each backend. - GLEW: Making ES extensions optional in generic glew lib (which will contain extensions from both desktop OpenGL and OpenGL ES) and also glewinfo now gives information on OpenGL ES extensions supported. >From the UMM side: DMA buffer sharing API RFC v2 to linaro-mm-sig list BR, -- 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

[ACTIVITY] Multimedia WG status - wk36.2011 (20110905-20110909)

by Ilias Biris

Status report in : https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyReport Last meeting minutes: https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Notes/2011-09-06 == Highlights == * 1109: some small changes. There will be no speex codec optimization during 1109. That work was postponed for a number of reasons - mentioned in the status report above. Suffice it to say that the work did not make sense anymore. Despite this postponing of the optimization work for speex, there is possibility to make a speex package available through the Multimedia WG PPA to try on ARM. * 1109 [Community effort] - the x264 work was split a bit more - there are now 3 avenues for the optimization, through parameters, preload engine, and NEON. For 1109 the community folks will provide instructions on how to set parameters in order to enable real-time encoder for video conferencing - this will be provided in the wiki * OpenMAX presentation created and shared with linaro-dev (thread : http://lists.linaro.org/pipermail/linaro-dev/2011-September/007492.html) * UMM documentation updated - this needs to be hosted in a better place following Kiko's friendly reminders. * HDMI audio output has issue in certain resolution mode (1360x768) - bug https://bugs.launchpad.net/bugs/849625 has been reported and is being investigated now * Tom Gall is doing some side-by-side comparison of LJT on android using Nexus One devices. Possibly youtube material from this experiment. Let me know if you have questions or if something is unclear/missing from this report.

[ACTIVITY] OCTO status report - wk36.2011 (20110905-20110909)

by Ilias Biris

Status: https://wiki.linaro.org/OfficeofCTO/WeeklyReport Last meeting minutes: https://wiki.linaro.org/OfficeofCTO/2011-09-06 Highlights: - regarding 1109 work is progressing - details are in the status link above. The only item which may not be completed during 1109 is the runtime linker patches. The build farm was put together by Steve McIntyre (see http://blog.einval.com/2011/09/05#armhf_buildds for some details). - Mozilla discussions are ongoing - Loïc has provided some feedback on what is the preliminary scope, involving two potential threads : (performance optimised) Firefox on Android, and boot-to-gecko. Both seem to be areas where Linaro could contribute. - UMM work is progressing. Documentation is becoming available through presentations (see in https://wiki.linaro.org/OfficeofCTO/MemoryManagement?action=AttachFile&do=v… and https://wiki.linaro.org/OfficeofCTO/MemoryManagement?action=AttachFile&do=v…). Also there is material also from the Linux Plumbers in http://www.linuxplumbersconf.org/2011/ocw/events/LPC2011MC/tracks/117. - Also this coming week we will resume the Boot Architecture discussions.

[PATCH] ARM: EXYNOS4: convert boot_params to atag_offset

by Tushar Behera

Based on "ARM: introduce atag_offset to replace boot_params" by Nicolas Pitre (2bb9839e312ed55a6d5824ffa6077ce3d7d63b1e). Since boot_params variable is deleted from machine_desc, the variable is modified in the newer board files.
