perf scripts python: exported-sql-viewer.py: Fix use of TRUE with SQLite

2019-11-13T12:13:16+00:00

Prior to version 3.23 SQLite does not support TRUE or FALSE, so always use 1 and 0 for SQLite. Fixes: 26c11206f433 ("perf scripts python: exported-sql-viewer.py: Use new 'has_calls' column") Signed-off-by: Adrian Hunter Cc: Jiri Olsa Cc: stable@vger.kernel.org # v5.3+ Link: http://lore.kernel.org/lkml/20191113120206.26957-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf scripts python: exported-sql-viewer.py: Add Time chart by CPU

2019-10-07T15:22:17+00:00

Add a time chart based on context switch information. Context switch information was added to the database export fairly recently, so the chart menu option will only appear if context switch information is in the database. Refer to the Exported SQL Viewer Help option for more information about the chart.
