- Speex was released on Linaro Ubuntu evaluation build with NEON optimisation patches from upstream mailing list - version 1.2~rc1+git20090708+a6d05eb-1linaro1 is based on 1.2rc1
- libpng v1.5 was released with additional patches to allow NEON autodetection (was being detected manually before)
- A first experimental release of Alsa-UCM for Pulseaudio was done. The patch for pulseaudio alsa-module can be used to provide pulseaudio profiles and ports by alsa ucm configurations, and switch profile/port by pactl tools. Any settings could result in alsa mixer update, which can be checked by alsamixer.
- Libjpeg-turbo now includes compatibility for libjpeg8. Also collected performance measurements between libjpeg8 and libjpeg-turbo with libjpeg8 compatibility using tjbench on both intel and arm hardware
- DirectFB was released by ARM-China with NEON optimisations - DirectFB (www.directfb.org) is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware. Many 2D operations (such as blending, Color format conversion, Blitting and so on ) have been accelerated by NEON technology by this release
Memory management work: Development of dri2proto, updating libdri2 to support dri2video and dri2video test app, updating mesa and implementing the core functionality in xserver against xf86-video-nouveau - patches upstream, also available from https://github.com/robclark. The patches can also be checked via http://patches.linaro.org/team/linaro-multimedia-wg/
Also for memory management - CMA debugfs and tracing patches have also been sent upstream - they can be accessed via http://git.linaro.org/gitweb?p=people/bgaignard/linux-snowball-cma-test.git;a=summary
ARMHF port has now a reserved space in the debian archive - ftp://ftp.debian.org/debian/dists/sid/main/binary-armhf/
- Official ARMHF Debian builds are now pending to start building
- Fixed OMAP4 porting issues to common clock, Panda is 100% converted to use Common Clock Framework, submitted v3 of the common clock code to LKML.
