Which specific versions of the kernel and oprofile are you using. Do you have pointers to the specific sources for those? > > -Will Hi Will, I'm using oprofile-0.9.9 from oprofile.sourceforge.net. I did a 'diff' between oprofile-0.9.9/utils/opcontrol and the opcontrol script on my target (mips) system, and they're both identical. The kernel I'm using is unfortunately chip-vendor (broadcom) supplied, and there's no public repository for it on the internet. However, it's very close to mainline linux-2.6.27.18/ -- mostly modified under drivers/ and arch/mips/ to add support for their SoCs. I have these kernel options enabled for profiling: # zcat /proc/config.gz | grep prof -i CONFIG_ARCH_SUPPORTS_OPROFILE=y CONFIG_PROFILING=y CONFIG_OPROFILE=y CONFIG_HAVE_OPROFILE=y Andrew ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
