System info: oprofile built-in, no module support 2.5.62 kernel, PowerPC (with ppc64 changes), and the oprofilefs filesystem mountable. $ utils/op_help Unable to open cpu_type file for reading Forgot to load the oprofile kernel module ? invalid cpu type -1 ! # utils/op_start --vmlinux=/boot/vmlinux-2.5.62 FATAL: Module oprofile not found. Couldn't load oprofile.o module /proc/sys/dev/oprofile does not exist. /dev/oprofile is undocumented AFAIK. I guess I need an /etc/fstab entry for it? |

No. Do opcontrol --init. regards, john |
