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.
Changes in V3:
Re-base
Changes in V2:
perf tools: Make it possible to see perf's kernel and module memory mappings - add dump to perf report (if no browser) as well as perf script - add 'perf --debug kmaps' option also to dump kmaps
