hi guys
i cant seem to find anything explaining what Unknown means, so i might just try asking here.
this report was made from a unity game running on a G51 devices
can i viewed that as the portion of the hardware resouces that are not being utilized at all?
if that is the case, should i be worry about it? and is there anything i can do to make this unknown part lower?
"Unknown" means that the tool analysis can't determine whether those parts of the application are CPU or GPU bound - the performance data is ambiguous and both processors are partially utilized but not fully loaded. The Streamline data is normally needed to investigate in more detail here.
if that is the case, should i be worry about it?
Perhaps - it may indicate a realy performance problem (e.g. tight CPU-GPU coupling breaking pipelining), or it may just be noisy measurement due to the style of workload.
HTH, Pete
can you share how you would further investigate the streamline data for this "Unknown" bit?
Step one: Check how well the CPU/GPU queues are being scheduled. If you are below your frame rate target you ideally want the dominant queue on CPU or GPU running all of the time. If that isn't happening you may have some behavior causing serialization which can reduce performance.Step two: Optimize the dominant part. E.g. if you are "mostly" fragment limited then use the other counters in Streamline to investigate the fragment workload (how well is early ZS working, how much over draw do you have, etc). The Mali Performance Counter guide for your GPU (https://developer.arm.com/documentation#q=Mali%20Performance%20Counters) should give more specific advice.
