[PATCH v4] perf: cs-etm: update ETM metadata format

by Mike Leach

The current fixed metadata version format (version 0), means that adding metadata parameter items renders files from a previous version of perf unreadable. Per CPU parameters appear in a fixed order, but there is no field to indicate the number of ETM parameters per CPU. This patch updates the per CPU parameter blocks to include a NR_PARAMs value which indicates the number of parameters in the block. The header version is incremented to 1. Fixed ordering is retained, new ETM parameters are added to the end of the list. The reader code is updated to be able to read current version 0 files, For version 1, the reader will read the number of parameters in the per CPU block. This allows the reader to process older or newer files that may have different numbers of parameters than in use at the time perf was built. Changes since v3 1. Fixed index bug (Leo) Changes since v2 1. Add error path print to improve --dump logging 2. Replace some hardcoded values with enum consts (Mathieu). Changes since v1 (from Review by Leo): 1. Split printing routine into sub functions per version 2. Renamed NR_PARAMs to NR_TRC_PARAMs to emphasise use as count of trace related parameters, not total block parameter. 3. Misc other fixes.
