Benchmarks & tests results

Mon Sep 26 12:03:27 UTC 2011

That was a very old one ... and it does not apply.
If you do FullViewportUpdate (what you do if you're using the main.cpp from Car3D)
 (... which you should to anyway on android (and any other eglfs platform))
you should be good.

So from my perspective it's a new/unknown bug/issue.

Hi

Indeed, I forgot to mention about scaling wheels and doors. Although I was playing around with the source code (you know, round corners :) - in my mind I didn't disable that. I have to investigate why it doesn't work, when I boot up my Linux again. I'll let you know.

The flicking is not visible on the video since camera light sensors smooth it. It's not big but it is there. The effect is similar when having a bad deinterlace in videos - I hope know what I'm talking about. I remember a discussion about some double-buffer issue but cannot find it anymore in the history. What was it about?

Regards
Lauri

I can't see the flicking/black-frames. Maybe a double-buffer problem?

Morning

Is there a short description somewhere how to run the tests and what are the prerequisites? The information coming to me at the moment is just so overwhelmingly big that I cannot cope with that :)

And also one question, the OpenGL performance looks very fast and stable but it's kind of a flicking. Seems like FPS is low or blank screens between frames (not sure but movement looks strange), am I doing something wrong?

Regards,
Lauri

Hello folks,

I manage to run almost all tests on android, some of them are crashing but most of them are running and surprisingly a lot are passing all tests.
The tests where made using dfb51925e136a96ed0fcdcfed140f0ac6158771a compiled in debug mode.

Next step is to try to modify Nokia's bm[1] tools to fit our needs :
 - add device parameter or should we use host parameter instead? This parameter is very important to group benchmarks by device model ("ro.product.name" parameter of getprop command).
 - add authentication support: I think adding ssl support will be the easiest and the safest, this way we can automatically accept benchmark results from everyone who has a certificate signed with our server certificate.

Cheers,
BogDan.
