Hi
Currently perf does not record module section addresses except for
the .text section. In general that means perf cannot get module section
mappings correct (except for .text) when loading symbols from a kernel
module file. (Note using --kcore does not have this issue)
Here are a couple of patches to help shed light upon and slightly improve
the situation.
Adrian Hunter (2):
perf script: Make it possible to see perf's kernel and module memory mappings
perf symbols: Slightly improve module file executable section mappings
Regards
Adrian
