I collected some GPU information on Intel XE driver and I am trying to understand what the numbers mean.

The data for those tracks comes from the DRM ftrace event. Specifically the bit after the "sched-" prefix corresponds to the "name" field of the DrmSchedJob and DrmRunJob ftrace events: https://cs.android.com/android/platform/superproject/+/android14-qpr3-release:external/perfetto/protos/perfetto/trace/perfetto_trace.proto;l=8265?q=DrmSchedJob

As for what they mean beyond that, it's well outside our area of expertise. But it may point you in a direction for further investigation.
