PAPI Forum

Hi. I am running Ubuntu 11.04, kernel 2.6.38-12, and after running the PAPI configure script and 'make', when I run 'make test' I get the following error:

cd ctests; make CC="gcc" CC_R="gcc -pthread" CFLAGS="-I.. -g -DSTATIC_PAPI_EVENTS_TABLE -DPEINCLUDE=\"libpfm4/include/perfmon/perf_event.h\" -D_REENTRANT -D_GNU_SOURCE -DUSE_COMPILER_TLS -Wall -I/home/skabala/Downloads/papi-4.2.0/src/libpfm4/include -DSUBSTRATE_USES_LIBPFM -DSUBSTRATE_NAME_perf_events -Wextra -DPAPI_NO_MEMORY_MANAGEMENT" TOPTFLAGS="-O0" SMPCFLGS="" OMPCFLGS="-fopenmp" NOOPT="" LDFLAGS=" " LDL="-ldl" LIBRARY="../libpapi.a" papi_api serial forkexec_tests overflow_tests profile_tests attach multiplex_and_pthreads shared

When I run 'modprobe powernow-k8' and then 'dmesg | grep powernow' it detects my CPU and lists the supported P-states (8 allowed frequencies). I think powernow is the PMU for my AMD processor, right? I also checked my BIOS and ACPI is enabled. I really don't know what to try at this point... Any help would be greatly appreciated!

PMU in this case means performance-monitoring unit, not Power.

Somehow your processor is not being detected. Does "dmesg" say anything about perf_events? You're not trying to run inside of a virtual machine, are you?

It's set up as a dual-boot using grub, but I'm not running a virtual machine. The only 'perf' lines in the dmesg log are:

> grep -i 'perf' /var/log/dmesg
[ 0.140000] Performance Events: AMD PMU driver.
[ 13.259687] [drm] nouveau 0000:01:00.0: 2 available performance level(s)

My kernel is 2.6.38-12-generic, and I read that support for this particular processor's on-chip GPU wasn't officially added to the kernel until 3.0. Maybe some other things didn't quite make it before 3.0 either... I chose Ubuntu 11.04 over 11.10 for other reasons, but if I have to upgrade for full kernel support of the processor, I suppose I could try that. So far other things have been fine for that CPU with 11.04.

can you post a copy of your /proc/cpuinfo file? Your processor might be too new to be supported by PAPI, but it would be nice to add support.

Sure, I've listed /proc/cpuinfo at the end. I upgraded to Ubuntu 11.10 (with no changes to the default kernel), and still no luck after configure and make succeed. Several of the 'perf' files PAPI's configure script looks for don't appear to be present; though, perf_event_paranoid and libpfm4 includes are :

$ ./configure | grep 'perf'
checking for perf_event workaround level... autodetect
checking for high performance thread local storage... __thread
checking for /sys/class/perfctr... no
checking for /dev/perfctr... no
checking for /sys/kernel/perfmon/version... no
checking for /proc/perfmon... no
checking for /proc/sys/kernel/perf_event_paranoid... yes
checking for libpfm4/include/perfmon/perf_event.h... yes

You have an AMD fam12h CPU. libpfm4 (and thus PAPI) currently does not support this chip yet. I'm looking into what it will take to get this chip supported.

The development version of PAPI in CVS should support AMD fam12h now. Please try it and let us know if it works.
