Tom, what are your thoughts on these?

1) We have /proc/kallsysm, not sure what symtab is
2) Does some sampling run need to be run manually first?
13) A sysroot issue?
15) Python is installed and runs a simple print test, are there some debug or other dependencies the image needs to install possibly?</thetext>

&gt; 

We haven&apos;t used perf test as a functional test in the past, but should probably make sure it runs cleanly for 1.7.   Despite the warnings, basic perf functionality works fine.

In any case, we&apos;ll need to go through each failure and track down the cause, but verbose output currently shows the following: 

&gt; 1) We have /proc/kallsysm, not sure what symtab is

Looking at the vmlinux_path (6 entries long)
symsrc__init: cannot get elf header.
Using /boot/vmlinux-3.10.32-ltsi-yocto-standard for symbols

Maps only in vmlinux:
 c1971000-c1a01057 0 [kernel].init.text
 c1a01058-ffffffffffffffff 0 [kernel].exit.text


&gt; 2) Does some sampling run need to be run manually first?

No, it looks like a consequence of not using real hardware.  With real hardware:

 2: detect open syscall event                              :
--- start ---
---- end ----
detect open syscall event: Ok


&gt; 13) A sysroot issue?

Probably a missing native dependency.

&gt; 15) Python is installed and runs a simple print test, are there some debug
&gt; or other dependencies the image needs to install possibly?

Probably same cause as 13.</thetext>
