Android framerate not correct

Hello,

 

I'm running Android 5.1.1_2.1.0-ga release with kernel 3.14.52 and are having problem getting the framerate up to 60fps (this worked earlier on kitkat release with kernel 3.0.35).

 

The display is configured with a pixelclock for 60fps (for our display and resolution pclk is 10MHz) but framerate for Android's SurfaceFlinger get limited to 30fps (limited by IPU interrupts?).

 

When running a camera overlay in 60fps it seems to output in the correct rate, so I believe the display setup is correct. But for some reason the default framebuffer is rate limited to 30fps.

 

Has anyone else experienced this problem also?

 

 

We're using MIPI DSI (but problem also seen with MIPI DPI).

 

Framerate is shown in logcat after "setprop debug.sf.showfps 1" and "killing" surfaceflinger process.
