pti-gpu How to get L3_BYTE

In the README the metrics for a csv are queried here: https://github.com/intel/pti-gpu/blob/master/tools/unitrace/README.md#list-contents-of-the-metric-data-file Two of the metrics listed for that file are L3_BYTE_READ[bytes] and L3_BYTE_WRITE[bytes]. These are metrics I would like to use in my own work, but are not listed in any of the metric-groups for me.

I've checked the output of unitrace --metric-list and these are no present. I've attached the output I see from unitrace --metric-list metric_list.txt.

I imagine the metric list is being queried from another system (level zero maybe?) so I'm probably on the wrong version of something, but I don't know what. Any help would be greatly appreciated.

@FMarno Looks like you are using a driver that does not gave these metrics exposed. Can you please share your driver version?

@zma2 I'm not sure which driver you are referring to, level-zero? Do you know how I can get that information? Does this help? (taken from sycl-ls --verbose)

@FMarno have you tried the latest driver?

Thank you, but I'm no longer working on a project where this would be helpful.

Hello! I have the same issue trying to set up VTune profiler. I have dev.i915.perf_stream_paranoid set to 0 and I am using the latest rolling 2523.12 driver with the Max 1100 Datacenter GPU. What else do I need to get these metrics?
