README
(Work in progress, POC) A simple viewer for raw Intel PTrace data stored in SQLite database.
### How to use
Only Linux and Intel CPU are supported. Record you program:
sudo perf record --kcore -e intel_pt/cyc/ ./lsm-tree
Then dump all data to SQLite using [export-to-sqlite.py](https://github.com/torvalds/linux/blob/master/tools/perf/scripts/python/export-to-sqlite.py) script:
sudo perf script --itrace=bep -s ~/export-to-sqlite.py sqlite branches calls
Open database in perfscope:
Perfscope is similar (and can be considered as fork of) to the script [exported-sql-viewer.py](https://github.com/torvalds/linux/blob/master/tools/perf/scripts/python/exported-sql-viewer.py) which
supports building call tree. Implementing additional staff is in progress.
### Build
* Generate JOOQ pojos `./gradlew generateJooq`
* Build `./gradlew clean generateJooq build`
