ARM Status

Q/omap4: porting of tilt-3.4 [1] on top of Q 3.5 master continues.
The resulting kernel is available here: http://kernel.ubuntu.com/git?p=ppisati/ubuntu-quantal.git;a=shortlog;h=refs/heads/ti-omap4-tilt-34-on-35
The entire patchset is available here: http://people.canonical.com/~ppisati/ti-omap4-tilt-34-on-35/tilt-3.4/
The “done” directory contains the patches i already ported(646), “skipped” contains the patches left for later evaluation(27) and “already” contains the patches that were already found upstream(52) – 725 out of 1708 patches were handled in total, so far so good.

ARM Status

Q/omap4: Ubuntu-3.4.0-202.7 contains a new TI BSP (tilt-tracking @ 44fef05d56961d0f34178e3c7ca4e362948e3107) that fixes the video issue many reported.
A new kernel (Ubuntu-3.4.0-203.8) is already queued and it improves upon the previous one by fixing a wl oops on boot, disactivates the interactive cpufreq governor (that spammed kernel logs with thousands of “kinterative process stuck for more than 120s”) and eliminates /proc/config.gz.
