Mali GPU Counters

Hi,

I am trying to get all the GPU HW counters displayed by streamline.

I have built the debug build for DDK and for Linux I have enabled the configurations as mentioned in [1].

But I am just able to see the just the Mali core cycle counters and Mali external bus Access for rest of the Mali properties I get no live data. Is there I missing something here ?

Also is there a document which explains the MALI counters ? I mainly interested on GPU usage level (similar to CPU ones)

Cheers,

  • We can't do this automatically - the maximum GPU frequency (absolute, or thermally sustainable) is device specific.

    If you know this value you can use a custom expression to divide the counter by this frequency to determine a percentage. For example, if you know the top frequency is 1GHz you can compute the percentage as: 

    • ($MaliGPUCyclesGPUActive / (1000000000 * $ZOOM)) * 100

    Kind regards,
