[PATCH 23/85] perf scripts python: exported-sql-viewer.py: Add IPC information to Call Graph Graph

From: Arnaldo Carvalho de Melo
Date: Tue Jun 11 2019 - 15:05:17 EST


From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

Enhance the call graph to display IPC information if it is available.

Committer testing:

[acme@quaco adrian.hunter]$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db

Reports -> Context Sensitive Callgraph, then expand a few trees, then
select with the mouse and press control+C:
