Low 2D graphics performance on KitKat and Lollipop

emilmyhrman — Fri, 23 Oct 2015 08:53:10 GMT

Hi,

After upgrading to 4.4.3_2.0.0 we're having problems with low graphics performance, this seems to affect only 2D drawing.

I've been running the 0xBench app (0xbench - Comprehensive Benchmark Suite for Android - Google Project Hosting ) with 2D and 3D tests.

Android 4.4.2 using hwcomposer_viv.imx6.so, 3.0.35 kernel

Draw Rect test: 37 fps

Flying teapot: 60 fps

Android 4.4.3_2.0.0 using hwcomposer_fsl.imx6.so, 3.10.53 kernel

Draw Rect test: 7.0 fps

Flying teapot: 59 fps

Android 4.4.3_2.0.0 using hwcomposer_viv.imx6.so, 3.10.53 kernel

Draw Rect test: 6.9 fps

Flying teapot: 60 fps

Android 5.1.1 (beta) using hwcomposer_viv.imx6.so, 3.14.53 kernel

Draw Rect test: 6.8 fps

Flying teapot: 44 fps

Any ideas what would cause this?

I don't know if it's related but I've noticed that the function "eglSetSwapRectangleANDROID" is present in libEGL_VIVANTE.so for 4.4.2 release, but missing (or renamed to eglSetSwapRectangleVIV?) on Android releases. Which makes the call to eglSetSwapRectangleANDROID in surfaceflinger/DisplayDevice.cpp useless.

I've tested this with 5.1.1_2.0.0-ga release, and still not very impressive results.

Draw Rect performs at 5.9 FPS.

Any idea what could be wrong here?

Hi Emil,

This is a bug in the in the GPU driver, we already have found the root cause of this situation of performance drop, however fix will appear in 5.0.11p8 driver version in next BSP release.

Sorry for these inconveniences.

Regards

Excellent, thanks!

When is the next BSP release planned? Will this be the January(?) release? If I've understood correct that's when imx6DL will have official support for Lollipop 5.1.1.

Hi Sir,

The Android M6.0.1_1.0.0 have been released recently with 5.0.11p8 GPU driver , does the issue fix now ?

Can you provide me the related info ? Tks

Hi,

I have verified it and there are Reno improvement so far.

The GPU driver + Vivanta EGL libraries seems to be degrading performance in each new release.

In KitKat and JB 4.2_1.1.0, we used to get optimal performance to support 1080p@60 FPS video's

Why this thread is marked as "resolved"?

The GPU driver 5.0.11p8 in Android M still does not fix the performance issue - see results from Gurtaj Singh.

Any updates on this

Re: Low 2D graphics performance on KitKat and Lollipop

Yes, we still have this problem on Lollipop 5.1.1. I don't know why this is marked as resolved, someone at freescale/nxp must have assumed it is fixed?

No update??? We also find the poor performance in Android5 and 6 for iMX6.

Just have a simple try on Android 6.0.1 but only got 18.666 FPS on Draw Canvas test.
