Function_graph questions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Couple of questions:

1. The Fedora 14 kernel seems to be configured to support function_graph,
but not to actually support it - see
https://bugzilla.redhat.com/show_bug.cgi?id=695283
Any ideas what's going on there?

2. Is it possible to specify a syscall instead of a function call with
trace-cmd -g, e.g. if I want to see all (and only) the functions called by
pivot_root? (Haven't been able to try this at all because of the first
problem.)

Regards,
Robin Green
