Hotspot

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. The main feature of the hotspot is visualizing a perf.data file graphically. The timeline allows filtering the results by time, process, or thread. The data views will update accordingly. You can also launch perf from the hotspot, to profile a newly started application, or to attach to an already running process(es). Building hotspot from a source gives you the latest and greatest, but you'll have to make sure all its dependencies are available. Most users should probably install a hotspot from the distro package manager or as an AppImage.
