From 8fab7843a15078814764e01c303d175c92b500c1 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 9 Mar 2018 11:14:37 +0100 Subject: [PATCH] perf c2c record: Record physical addresses in samples We are going to display NUMA node information in following patches. For this we need to have physical address data in the sample. Adding --phys-data as a default option for perf c2c record.
