GPU's cycles in Streamline

JPJ

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 table file (found it in /sys/devices/platform/18500000.mali/dvfs_table) it seems the max frequency is 702MHz (for some reason I can't find any Arm official page with the max frequency of this GPU though) - and I'm relying in my interpretation of the values in there.

So, my question is, is it possible that the GPU is being underutilized or that DVFS has kicked-in (although I made sure to have the device running on top of an ice-pack); or both?

Cheers.

    I can definitely confirm that, thanks. I also looked into /sys/devices/platform/18500000.mali/clock and had a look at the changing frequencies (325000 was matching what I was seeing in Streamline at certain points). This frequency is listed in found it in /sys/devices/platform/18500000.mali/dvfs_table.
