Lowering the freq to 4kHz gets me to where I think you was at this
point:

[root@zoo ~]# perf test -v 21
21: Test object code reading                               :
--- start ---
Looking at the vmlinux_path (6 entries long)
symsrc__init: cannot get elf header.

Test object code reading: FAILED!
[root@zoo ~]# 

I.e. we need the follow on patches to fix this issue, right?

I'll merge my changes with your first patch and continue from there.
