Subject: [PATCH 11/43] perf scripts python: export-to-postgresql.py: Export Intel PT power and ptwrite events
From: Adrian Hunter <adrian.hunter@...el.com>
The format of synthesized events is determined by the attribute config.
For the formats for Intel PT power and ptwrite events, create tables and
populate them when the synth_data handler is called. If the tables
remain empty, drop them at the end.
The tables and views, including a combined power_events_view, will
display automatically from the tables menu of the exported
exported-sql-viewer.py script.
Note, currently only Atoms since Gemini Lake have support for ptwrite
and mwait, pwre, exstop and pwrx, but all Intel PT implementations
support cbr.
