Description Andrei Gherzan 2013-09-09 16:30:57 UTC

When running "perf test -v 3", the test fails with this log:

1: vmlinux symtab matches kallsyms:
--- start ---
Looking at the vmlinux_path (6 entries long)
Using /boot/vmlinux-3.0.35-4.0.0+yocto+g3383d80 for symbols

Maps in vmlinux with a different name in kallsyms:
Maps only in kallsyms:
---- end ----
vmlinux symtab matches kallsyms: FAILED!

We aware that in order to test this, vmlinux image must be installed (linux-vmlinux). Will patch poky to have this as a rdepends to perf.

So you got this fixed?

Typo: We aware = be aware

I don't have a fix for this yet.

Good but are you looking at this?

Comment 4 Andrei Gherzan 2013-09-18 23:11:14 UTC

Hello Otavio,

I invested a lot of time in this but it seems that I can't find the source of the issue. Maybe you can take a look too. Or a least give me a hint or so.

Thanks,
Andrei

This needs to be check, so I am setting it to NEW.

Following a long communication chain I ended on this link
http://thread.gmane.org/gmane.linux.ports.arm.kernel/181392/focus=181597

There is a hardware limitation in i.MX6 that don´t allow perf to work.
