• GPU's cycles in Streamline

    Hi guys,

    I need some clarification in regards to the GPU Active ($MaliGPUCyclesGPUActive) counter on a Mali-G76 (not really specific to this GPU though) in a Samsung S10e.

    I'm getting a total of ~310 mega-cycles in 1 sec. From a quick look at the DVFS…

    I guess these signals should be asserted while PSEL is high like PADDR…
