Hi -
Running perf test on 3.10-rc6 gives some unexpected behaviours.
This is on a dual Cortex A9 board with perf userland cross-built from
same tree as the kernel.
root@aa9-eb:~# perf test
1: vmlinux symtab matches kallsyms : FAILED!
2: detect open syscall event : Ok
3: detect open syscall event on all cpus : Ok
4: read samples using the mmap interface : Ok
5: parse events tests : Warning:

Ok
6: Validate PERF_RECORD_* events & perf_sample fields : FAILED!
7: Test perf pmu format parsing : Ok
8: Test dso data interface : Ok
9: roundtrip evsel->name check : Ok
10: Check parsing of sched tracepoints fields : FAILED!
11: Generate and check syscalls:sys_enter_open event fields: Ok
12: struct perf_event_attr setup : (omitted) Ok
13: Test matching and linking mutliple hists : Ok
14: Try 'use perf' in python, checking link problems : FAILED!
15: Test breakpoint overflow signal handler : FAILED!
16: Test breakpoint overflow sampling : FAILED!
17: Test number of exit event of a simple workload : FAILED!
18: Test software clock events have valid period values : Ok
I started tracing the first failure... it stops because it can't find
"_stext" in /proc/kallsyms. But it is there
root@aa9-eb:~# cat /proc/kallsyms | grep _stext
800081c0 T _stext
test 5 (parse event tests) seems to be badly broken.
The others may be due to missing some config somewhere.
Any ideas what I am (or perf is) doing wrong?
