From 092772955568fa848b1e782e6cb3fa395eccea81 Mon Sep 17 00:00:00 2001 From: Mike Leach Date: Fri, 31 Mar 2023 06:56:43 +0100 Subject: perf cs-etm: Move mapping of Trace ID and cpu into helper function The information to associate Trace ID and CPU will be changing. Drivers will start outputting this as a hardware ID packet in the data file which if present will be used in preference to the AUXINFO values. To prepare for this we provide a helper functions to do the individual ID mapping, and one to extract the IDs from the completed metadata blocks.
