KernelShark 1.0 is Here; What Does that Mean?
summary
KernelShark 1.0 is a Qt front end for Ftrace that replaces the old GTK prototype, is rewritten in Qt, and ships faster rendering, markers that map events to CPUs, and plugins that compute things like wakeup-to-schedule latency (measured at 48 microseconds in the demo). It records via trace-cmd (recorder needs root), filters and zooms traces, supports Python plugins for post‑processing, and has working prototypes for VM/host merge and a planned unified tracing library for large-scale analysis.
