GPU Profiling and Debugging with Sokatoa Built on Theia
summary
Sokatoa is a Vulkan GPU profiler for Android built on Theia that integrates Perfetto for traces, gfxr for API capture and replay, and Theia’s code editor for shader edit & replay; users capture from a USB device, pull Perfetto and gfxr files, view per-frame draw calls and GPU counters, edit cross‑compiled shader source, recompile and replay modified frames, and compare runs side‑by‑side. Theia enables backend-only extensions for vendor plugins, it targets desktop or cloud, and the prototype is functional but still buggy.
