Subject: [PATCH 0/4] perf annotate: Enable cross arch annotate
Date: Tue, 28 Jun 2016 17:06:43 +0530 [thread overview]
Message-ID: <1467113807-29571-1-git-send-email-ravi.bangoria@linux.vnet.ibm.com> (raw)
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 [PATCH] vs [RFC]
- Removed global var 'arch__ins' and pass arch info till ins__find
