Isnt because only interactive has the "butter" optimizations?

Ya but half the "butter" stuff is simply the touchboost to Interactive. Giving that to OnDemand is the biggest thing right there

Random BSOD
Hi Franco,

I've been running R7 for a few days (since it came out) and have got several random BSOD while the tablet was in idle (sometimes with wifi on, sometimes in airplane mode).

Running factory JB 4.2.2 with SuperSU 1.09 and as of today, SuperSu 1.10 with TWRP 2.4.1.0 recovery.

BSODs happened with both versions of SuperSU as well.

Franco settings are: ondemand governor, min CPU frequency: 200, max 17000, IO Scheduler: deadline, westwood TCP congestion avoidance

attached is my kmsg

Cheers and keep up the great work!

I'm sure Franco will correct me if I am wrong, but I was under the belief that any watchdog resets:
Quote:

"Last reset was system watchdog timer reset (RST_STAT=0x100000)"

were not from the kernel and were instead due to a deadlock in the rest of Android... I think when a reset is triggered by watchdog you can find the information in /data/anr/traces.txt and from that you might be able to determine what caused the core Android Framework to stop responding.

The only time I have gotten random reboots is from a memory leak in Android 4.2.x

Thanks for the info, although I havent understood much of it :s

I had a look at /data/anr/traces.txt.bugreport, cant understand a thing either.. oddly enough, the only dates showing up in there are from February 15th... but I had the problem happening every couple days since as well too.

Ironically, my mobile that is running CM nightlies is more stable than my tablet running factory ROM

Franco, is it true that the Nexus 10 HDCP has to be bypassed at the Kernel level regardless of the setting in Developer Options?

Reference this thread: http://forum.xda-developers.com/show...2006403&page=3

I'm trying to record my N10 via HDMI to showcase my apps.

Following up on my SoDs, I've restored the backup of the factory kernel a couple days ago and havent had any problems since...

So something in FK R7 was definitely causing me problems.

This also fixed my erratic FPS with Beats, Advanced Rhythm Game, thanks!

Is there any guidelines for figuring out governor tweaking?
