Hi, I would like to add it is an insane amount of work. I have documented some tracepoints. Maybe this can help. https://git.eclipse.org/c/tracecompass/org.eclipse.tracecompass.git/tree/analysis/org.eclipse.tracecompass.analysis.os.linux.core/src/org/eclipse/tracecompass/analysis/os/linux/core/trace/IKernelAnalysisEventLayout.java<https://git.eclipse.org/c/tracecompass/org.eclipse.tracecompass.git/tree/analysis/org.eclipse.tracecompass.analysis.os.linux.core/src/org/eclipse/tracecompass/analysis/os/linux/core/trace/IKernelAnalysisEventLayout.java?id=01f2a5074ceebbc1ceaf2643c1aff5168a61ed4b>
For the syscalls, take a look at this, it may help? https://git.eclipse.org/c/tracecompass/org.eclipse.tracecompass.git/tree/analysis/org.eclipse.tracecompass.analysis.os.linux.core/res/syscalls.tsv Also, if you feel like enhancing the list, we'd be thrilled. 😉 As the author of these doc patches, I can confirm, it's a lot of not rewarding work.

For internal kernel tracepoints like sched_switch, there is no documentation of the meaning of each field at the moment. This state is the same as the upstream Linux kernel trace event. You'll have to figure it out on your own. Documenting each field of the ~500-1000 Linux kernel tracepoints is no small task.

Is it exactly in the CTF syscall event?

We saw events such as sched_switch, but the payload cannot be understood easily. Where we can find the document to explain the LTTng payload and parameters?
