This project is a KDAB R&D effort to create a standalone GUI for performance data. As the first goal, we want to provide a UI like KCachegrind around Linux perf. Looking ahead, we intend to support various other performance data formats under this umbrella.
You can also launch perf from hotspot, to profile a newly started application or to attach to already running process(es). Do take the caveats below into account though.
Building hotspot from source gives you the latest and greatest, but you'll have to make sure all its dependencies are available. Most users should probably install hotspot from the distro package manager or as an AppImage.
Note: Hotspot is not yet packaged on all Linux distributions. In such cases, or when you want to use the latest version, please use the AppImage which will work on any recent Linux distro just fine.
Please use the latest Continuous release to get the most recent version. If it doesn't work, please report a bug and test the latest stable version.
