Perf can currently only support code navigation (branches and calls) in annotate when run on the same architecture where perf.data was recorded. But cross arch annotate is not supported.
This patchset enables cross arch annotate. Currently I've used x86 and arm instructions which are already available and adding support for powerpc as well. Adding support for other arch will be easy. I've created this patch on top of acme/perf/core. And tested it with x86 and powerpc only. Example: Record on powerpc: $ ./perf record -a Report -> Annotate on x86: $ ./perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc Changes in v3: - Optimized patch that enables annotate on powerpc - Corrected one memory leak v2 link: https://lkml.org/lkml/2016/6/29/278 Naveen N.
