# An example of using this script with Intel PT:
|
|
#
|

# $ perf record -e intel_pt//u ls

# $ sqlite3 pt_example
|

# sqlite> .header on

# sqlite> select * from samples_view where id < 10;

# An example of using the database is provided by the script

# call-graph-from-sql.py. Refer to that script for details.

# The database structure is practically the same as created by the script

# export-to-postgresql.py. Refer to that script for details. A notable
|
|
# difference is the 'transaction' column of the 'samples' table which is
