OK, after some wrestling, I got oprofile installed in my OS (buildroot 2011.02- rc1) and my kernel (xilinx patches 2.6.35+). When I start oprofile, I get the following: # opcontrol --vmlinux=/vmlinux The specified file /vmlinux does not seem to be valid Make sure you are using the non-compressed image file (e.g. vmlinux not vmlinuz) # file /vmlinux /vmlinux: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), statically linked, with unknown capability 0x41000000 = 0x11676e75, with unknown capability 0x10000 = 0x90402, not stripped I used the vmlinux generated found in ../linus-2.6-xlnx/vmlinux What's wrong with it ? -- Guillaume Dargaud http://www.gdargaud.net/ _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
