BUG: MaliGPUActiveCy declaration likely incorrect for G715 and G615

[reubenscratton]

In the source file all_gpu_counters.cpp, line 11492, the MaliGPUActiveCy counter has been declared with the constant MaliGPUActive2Cy (note the '2').

This results in garbage counter values being returned for MaliGPUActiveCy on a Google Pixel 9 Pro (which has a G715 GPU).

Looks like same error affects G615 in same source file.

What is MaliGPUActive2Cy anyway? I cannot find any documentation for it.

Hi Reuben,

There is a hardware errata on Mali-G715 series hardware for the usual MaliGPUActiveCy counter, so the MaliGPUActive2Cy version is a workaround that is used only on this hardware generation (but it doesn't count quite the same thing).

I'll see if we can iron this out in the code generator so that only the workaround counter is exposed, under the original name. It will still count a subtly different metric though.
