Performance Advisor errors

Hi.

I need help with generating the report using Performance Advisor.

I get the following error when generating the report for Mali-G77 MC7 Valhall.

Fetching data...
Preparing report type html...
Problems were found preparing html report:
ERROR: Cannot find Execution Engine cycles. Make sure your capture includes 'Mali Core EE Instructions - Executed' / Mali Core EE Instructions - Executed instructions'.

The problem is, there is not counter which PA is asking for. It was asking for more counters as well, which I added and those errors were gone, but this counter doesn't seem to exist for G77 (it is available for Bifrost though! )

I tried getting PA report on Mali-G71 MP2 Bifrost as well, but I got the following error:

Extracting zip file to a temporary directory.
Creating report database in capture directory...
Importing capture...
Fetching data...
Preparing report type html...
Processing data...

I would be grateful for any help with this. 

Thanks.

  • Hi Chakshu,

    Thanks for getting in touch, and sorry you’ve been having problems getting started.

    We’ve just released Arm Mobile Studio 2020.1 - it was published yesterday. This new release will definitely fix your first problem as it adds Performance Advisor support for the Mali Valhall GPUs; they were not supported in the version of Performance Advisor released in Mobile Studio 2020.0.

    You can download the latest version from here:

    I will raise the second issue that you reported with the engineering team, but it might be worth trying out the new release here also. We’ve fixed a number of stability issues, so there is a chance that it is fixed. If that doesn’t work are you able to share the Streamline .apc capture? This makes it faster for us to reproduce your problem and provide a solution.

    Kind regards,
    Pete
