Current published trees are based on .32 (used for the coming-soon froyo release that's been in late QA for a while now) and forward development is moving to .34 post final (or in the case of tegra2, tracking .34-rc series as it happens). We've been actively snapping up to track mainline since we started doing this around 2.6.16. We'd *love* to be able to get more stuff sanely upstream instead of maintaining branches and rebasing every other mainline release or so. > The issue was that when I originally noticed the patch series was being > considered for mainline again was that one effect of using it in a > mobile phone with the standard Linux embedded audio subsystem would be > to break use cases such as audio on voice calls, which isn't really > desirable, and that there was no roadmap for how to fix that or any > other subsystems with similar issues.

I'd love to have a separate discussion on using standard linux embedded audio for mobile devices -- one of my goals for 2010 is to try to migrate from our "one off" approach on MSM to making use of ALSA and standard interfaces. I have a lot of questions about handing encoded data (mp3/aac/etc) that will be processed by the DSP, how to approach routing control, and how to best interact with the user/kernel interface, etc. Brian _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
