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 have to extend thanks for the detailed explanation as well. Great stuff!
I have two additional questions:
1. Is there a recommended way to quickly benchmark the device on app startup and set various budgets / LOD tweaks accordingly, so that application is running as close to the thermally sustainable threshold?
2. Is there a recommended way to track energy usage / temperature so that the application can adapt in run-time to current conditions device is in and keep the workload sustainable yet optimal?
Also, any resource pointers / links relevant to above questions are more then welcome.
Thank you in advance, Milan
Hi Speedym, Would you mind raising this as a new discussion thread please; it makes searching the forums for other users a lot easier. Thanks, Pete
Hi Pete!
Yup, good idea, will do.
