| |
Hi,
I'm looking kernel symbol mismatch issue, and found something in perf kmem code. The commit e727ca73f85d ("perf kmem: Resolve kernel symbols again") added perf_session__create_kernel_maps() but I don't know why. Why did it miss the MMAP event?
I think if we create a kernel maps at report time, it might not match to samples in a perf.data if it's recorded on a different kernel. This is the main reason of the mismatch problem I'm currently chasing IMHO. What am I missing?
Thanks, Namhyung
