Summary

• Added basic infrastructure to support Furiosa Warboy NPU devices
• Created new furiosa module with FuriosaReader implementing the GpuReader trait
• Added platform detection for Furiosa devices via furiosactl command
• Integrated Furiosa support into the reader factory for Linux systems

Implementation Details

• New Module: src/device/furiosa.rs - Contains the FuriosaReader struct with placeholder implementations for parsing furiosactl output
• Platform Detection: Added has_furiosa() function to check for furiosactl availability
• Reader Factory: Updated to instantiate FuriosaReader when Furiosa NPUs are detected
• Module Exports: Added furiosa module to device mod.rs

Next Steps

The basic abstraction layer is now in place. Future work will include:

• Implementing actual parsing of furiosactl output for device metrics
• Adding process information collection for Furiosa NPUs
• Testing with real Furiosa hardware

Test plan

• Verify the code compiles without errors
• Confirm no regression in existing GPU detection (NVIDIA, Apple Silicon, Jetson)
• Test on system with Furiosa NPU (when available)
