The table and view will show automatically in the exported-sql-viewer.py script. If the table ends up empty, then it and the view are dropped. Committer testing: Use the exported-sql-viewer.py and look at "Tables" -> "context_switches": id machine_id time cpu thread_out_id comm_out_id thread_in_id comm_in_id flags 1 1 187836111885918 7 1 1 2 2 3 2 1 187836111889369 7 1 1 2 2 0 3 1 187836112464618 7 2 3 1 1 1 4 1 187836112465511 7 2 3 1 1 0 Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/r/20190710085810.1650-21-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> 2019-07-10perf scripts python: export-to-sqlite.py: Add has_calls column to comms tableAdrian Hunter Now that a thread's current comm is exported, it shows up in the call graph and call tree even if it has no calls. That can happen because the calls are recorded against the main thread's initial comm. Add a table column to make it easy for the exported-sql-viewer.py script to select only comms with calls. Committer notes: Running the export-to-sqlite.py worked without warnings and using the exported-sql-viewer.py worked as before.

SQLite does not seem to mind but the fix was needed for PostgreSQL (export-to-postgresql.py script), so do the same fix for the SQLite. It is more logical and keeps the 2 scripts following the same approach.

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.
