Hello,
I have an odroid xu3 board equipped with mali T628(MP6). I run an example called "simpletriangle" and profile the data through DS5. Mali gpu breaks up the scene into tiles and renders a tile(16*16) once a time. When running the example "simpletriangle", I notice that the pmu counter "tiles rendered" is strange. The screen resolution is 1280*720, and the number of tiles rendered should be 3600(1280 * 720 / 256), but DS5 shows the number is 7200(within one frame). So, the gpu renders two frames a time?
Actually I have no idea whether it is a compositing window system. I think the pmu counter "tiles rendered" should be the number of tiles the gpu rendered within 16ms (one frame). If it is a compositing window system, the "tiles rendered" will be 7200? Why? Could you explain in detail?
If it is a compositing window system, the "tiles rendered" will be 7200?
* 3600 from the application
* 3600 from the compositor (if the compositor uses the GPU - not all do)
