perf scripts python: export-to-sqlite.py: Export IPC information
Export cycle and instruction counts on samples and calls tables.
Committer testing:
First runs some workload collecting intel_pt with the 'cyc' ter just for
userspace:
[root@...co adrian.hunter]# perf record -o simple-retpoline.perf.data -e intel_pt/cyc/u ./simple-retpoline
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.035 MB simple-retpoline.perf.data ]
[root@...co adrian.hunter]#
Then use the export-to-sqlite.py script to see if the changes in this
cset don't make it to break and if the changes in the db schema are the
ones expected:
[root@...co adrian.hunter]# perf script -i simple-retpoline.perf.data --itrace=be -s ~acme/libexec/perf-core/scripts/python/export-to-sqlite.py simple-retpoline.db branches calls
2019-05-31 11:50:46.942710 Creating database ...
2019-05-31 11:50:46.949663 Writing records...
2019-05-31 11:50:47.224033 Adding indexes
2019-05-31 11:50:47.231599 Done
[root@...co adrian.hunter]#
Now lets use the db:
[root@...co adrian.hunter]# sqlite3 simple-retpoline.db
SQLite version 3.26.0 2018-12-01 12:34:55
Enter ".help" for usage hints.
sqlite> .schema samples
CREATE TABLE samples (id integer NOT NULL PRIMARY KEY,evsel_id bigint,machine_id bigint,thread_id bigint,comm_id bigint,dso_id bigint,symbol_id bigint,sym_offset bigint,ip bigint,time bigint,cpuinteger,to_dso_id bigint,to_symbol_id bigint,to_sym_offset bigint,to_ip bigint,branch_type integer,in_tx boolean,call_path_id bigint,insn_count bigint,cyc_count bigint);
sqlite>
Cool, the 'insn_count' and 'cyc_count' are there, now lets see if we can
use them in a query:
sqlite> select insn_count,cyc_count from samples where cyc_count > 1500 and insn_count < 10;
6|1507
sqlite> select insn_count,cyc_count from samples where cyc_count > 1500;
118|2210
140|1516
3783|1861
132|1521
6|1507
sqlite>
Seems to work :-)
