Trace Compass/Feature Roadmap
This page is meant to track all the higher-level planned features and feature requests. As features get implemented, we could move them to "Targeted for version x.y" and "Delivered in version x.y" sections. It would always track the "current" roadmap, but over time would also become a history of which feature was delivered in which version.
Contents
Planned for 3.0
- User-configurable periodic markers
- Custom charts
- Pin & clone of views (done)
- Time based import of traces/experiments
- Scalable segment store (done)
Wishlist
These features have been proposed and deemed interesting to have, but nobody has committed to work on them yet.
- Enhanced call graph analysis and views (partially done)
- Call stack views using data-driven analysis (incubator)
- Enhanced searching, filtering and highlighting in Gantt charts
- Data-driven analysis and view enhancements
- Cropping of traces
- Support for perf traces in standard perf.data
- Support for ftrace traces
- Documentation at https://www.kernel.org/doc/Documentation/trace/ftrace.txt
- Investigate if we could re-implement the KernelShark view using a generic time graph view
- Reduce the size of state system history files
- Timestamps (2x 64 bits) are repeated for every single interval. Low-hanging fruit (using protocol buffers?)
- Compress often-used values (including strings).
- Support for data-driven Sequence Diagrams
- Sequence Diagrams for PCAP traces
- Visually define data-driven state providers with state diagrams
- Aligned X axis (time) (Parts 2 and 3)
