Hi, is it correct that callgraphs are only available on ARM-XScale? What would have to be done to use callgraphs also on other architectures? Regards, Frank |

No. It's available on at least i386 and x86-64. > What would have to be done to use callgraphs also on other architectures? Make the kernel driver do tracebacks. john |

What is was trying to ask was: Are callgraphs available on ARM architectures where the CPU isn't XScale? From studying arch/arm/oprofile/common.c i concluded that the only ARM CPU which supports callgraphs ATM is XScale. It's the only architecture for which a spec structure is available. I'm especially interested if the code in arch/arm/oprofile/backtrace.c is generic enough to be used with other CPUs? Regards, Frank |
