Date: Wed, 28 Jan 2015 11:15:11 +0100 From: Martin Liška <mliska@...e.cz> To: a.p.zijlstra@...llo.nl, paulus@...ba.org, mingo@...hat.com, acme@...nel.org CC: linux-kernel@...r.kernel.org Subject: [PATCH] perf: introduce local DSO path lookup. Hi. Following simple patch introduces support for a local DSO lookup operation. Motivation is that if I have a perf.data file which is created on a different machine (perf record $very_long_path), using perf report with --symfs=$workdir expects a DSO to be located at: $workdir/$very_long_path. I think it would be much easier to copy a binary file to the $workdir and let perf lookup the working directory: $workdir/binary_filename.
