Git repository for "Legacy" 2.6.31 kernel moved..

We have finally abandoned gitorious.org for hosting our kernel git tree and moved it (with a significantly less confusing branch history, and much better performance on using the repo) to our GitHub account.

You can now access the kernel source from http://github.com/genesi/linux-legacy

Instructions on how to access the repository are on the above page (new URLs etc.)

Maverick October

Minor update to fix some annoying bugs and pull in some performance updates

No kernel update. Just userspace fixes to improve user experience:
  • Preinstall NEON optimized libc functionality. Note this means that TO2 systems may become unstable unless users edit the installed filesystem /etc/ld.so.preload file to remove the library location (you do not need to uninstall the imx-libc-neon package as any updates will only change the file on TO3+ systems). This will improve system performance on very large memory copies, string searching and so on (not so much on tiny amounts of data, in fact system performance may slow down on these). Multimedia and Xorg are the biggest beneficiaries.
  • Preinstall libpixman 2.23 for enhanced performance on Xorg fallbacks (this significantly speeds up things like changing the backdrop in GNOME. Unfortunately other apps that use pixman (firefox is the biggest example) use an internal version and do not directly benefit except from improved system graphics performance.
  • Updated packages for imx-boot-scripts fixes some PulseAudio problems, SPDIF module loading, and bumps the compressed swap cache to 128MB (ramzswap default)
  • Uninstall and remove cache for "prelink" as it seems to do more harm than good for performance (including spending a lot of time scanning the system every week, and soaking up compressed swap cache for no good reason)
  • Fix software-center not running
  • Maverick Updates that were pushed the day we released the image (including apt, tzdata and firefox update to fix the DigiNotar SSL certificate security issue)
For users not willing to reinstall, you can fix software-center by running the following in a terminal (this will take around 10 minute to complete):
sudo update-apt-xapian-index
sudo dpkg-reconfigure software-center
