Package: linux-tools-2.6.38
Version: 2.6.38-3
Severity: normal
File: /usr/bin/perf_2.6.38
Event types listed by "perf list" can't be used for profiling (at
least on my system).
My expectation was that "perf list" would list only events I could
actually use.
For example, note how instructions are counted but not cycles, even
though I ask for both:
"
johan@johansdator:~$ perf list|cat
List of pre-defined events (to be used in -e):
cpu-cycles OR cycles [Hardware event]
instructions [Hardware event]
cache-references [Hardware event]
cache-misses [Hardware event]
branch-instructions OR branches [Hardware event]
branch-misses [Hardware event]
bus-cycles [Hardware event]
[...]
johan@johansdator:~$ sudo perf stat -e cycles -e instructions echo foo
foo
Performance counter stats for 'echo foo':
<not counted> cycles
823 105 instructions # 0,000 IPC
"

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
