Hi,
I installed perfmon2 on an (2 x Intel Xeon Quad E5606) server. Although this is
a new generation 64 bits Xeon processor, the OS it has is a 32 bits Ubuntu
Linux. I can list events and sub-events through perfmon -L or perfmon
--show-events commands. Or even event descriptions through perfmon -i.
Nevertheless, when I try to monitor core events I get the following error:
$ pfmon --follow-all --aggregate-results -0 -3 --events=UNHALTED_CORE_CYCLES
--outfile=pfmon_out.txt ls
detection of unavailable registers failed, leave it to the kernel to decide
can't create perfmon context: Function not implemented
$ pfmon -e INST_RETIRED:ANY_P ls -ial /dev/null
detection of unavailable registers failed, leave it to the kernel to decide
can't create perfmon context: Function not implemented
and so on.
After patching the Linux kernel (2.6.29) with the perfmon-new-base-090219
patch, I configured it by choosing Intel pentium4/Xeon as the processor type.
Then, I compiled and installed the kernel successfully.
Afterwards, I download the libpfmon library and the pfmon application from the
CVS repository. I carefully compiled and installed them (along with their
software dependencies).
Could you please give me directions (or clues) on how to fix this?.
Thanks a lot,
Ulises
