Subject: [PATCH v2 0/3] Initial trace-cmd support for ftrace uprobes
Date: Thu, 24 Sep 2020 10:14:55 +0300 [thread overview]
Message-ID: <20200924071458.101326-1-tz.stoyanov@gmail.com> (raw)
Ftrace supports uprobes - trace events on user space applications.
Trace-cmd cannot configure uprobes, in order to support it this new
functionality is introduced:
- Function name to file offset mapping, this information is extracted
from the dwarf and ELF headers in the binary file.
- New options are added to "trace-cmd record" for setting a uprobe:
--uprobe file:function
--uprobe-ret file:function
[
v2 changes:
- Renamed some internal trace-cmd functions, to not overlap the bfd
library namespace. Suggested by Steven Rostedt.
