Syscalls symbols

[Desperado17]

Greetings,

I have a trace where I see a ?? for some symbols in hotspot. All other debug symbols are present and visible. I suspect that these symbols are supposed to be inside syscalls. Is there a way to verify this and show the syscalls?

Regards

Syscalls have symbols, so that's probably not it. Rather, it's either kernel internals (for which you need the kallsyms file), or symbols from some other library that is missing debug information. The summary page should tell you more on that matter.
