perf counters: problem with perf record

["Simon Kämpflein" <s.kaempflein@gmx.de>]

Hello,

I have a problem with the new kernel perf tools in kernel 2.6.31.6 (very
nice tools by the way). I like to monitor the cache-misses of a program.
"perf stat -e cache-misses program" works without problems, but I can't
get "perf record -e cache-misses program" working (even running as root
and CONFIG_PERF_COUNTERS=y):

Error: perfcounter syscall returned with -1 (Operation not supported)
Fatal: No CONFIG_PERF_COUNTERS=y kernel support configured?

strace of "perf stat":
SYS_336(0x8508da0, 0x1074, 0xffffffff, 0xffffffff, 0) = 3

strace of "perf record":
SYS_336(0x8508da0, 0xf85, 0xffffffff, 0xffffffff, 0) = -1 EOPNOTSUPP
(Operation not supported)

My CPU is a "Intel(R) Pentium(R) M processor 1.80GHz":
[    0.004337] p6 PMU driver.
