Hello,
I patched the kernel and installed both libpfm and perfmon, however I got
segmentation fault while I tried running command: "pfmon --help'. Could
anyone help me to figure it out please?
I am running Ubuntu 9.04 on kernel 2.6.29. I downloaded the latest version
of libpfm, perfmon, and the base system patch from the sourceforge page. My
processor is Intel core i7 920 and I adjusted related configuration when I
configured the kernel. Following is the debug message from gdb:
