gpu-smi v1.2.0 - Hardened Headless API & Linux Backend Parity

gpu-smi v1.2.0 - Hardened Headless API & Linux Backend Parity

Security + Linux catch-up release. No breaking changes: loopback --serve stays zero-config.

What's New in v1.2.0:

• Bearer token auth for --serve: --token / --token-file / GPU_SMI_TOKEN (constant-time compare). /health stays open for probes; / + /metrics require the token when one is set. Non-loopback --listen (e.g. 0.0.0.0 for LAN Prometheus scraping) refuses to start without a token (fail-closed).
• HTTP hardening: strict METHOD PATH routing with 405/404 (kills the old /metrics-evil substring confusion), loopback Host: check against DNS rebinding, removed Access-Control-Allow-Origin: * so random websites can't scrape your process list, 5s read timeout, proper Prometheus label escaping, nosniff + no-store headers.
• DLL sideload guard: System32/driver absolute paths are tried before bare names for ADL/HIP/system DLLs.
• Linux backend parity: full sysfs sensors (edge/hotspot/VRAM temps, gfx/mem clocks via hwmon + pp_dpm fallback, gpu_busy_percent, power + cap, PCIe width/speed, BDF, vbios, serial, driver version), per-process VRAM via /proc fdinfo (deduped by client-id, same overcount guard as Windows), HIP merge for names/CUs, connector-device phantom-GPU fix.
• Correct gfx IDs: shared PCI-device table fixes 7900 XTX -> gfx1100, 7800 XT -> gfx1101, 6900 XT -> gfx1030, Raphael -> gfx1036, Phoenix -> gfx1103 (were mislabeled).
• Token setup template: example.env (copy to .env, chmod 600); .gitignore now covers real secrets.

Downloads:

• gpu-smi-windows-x64.exe (1.0MB) - Portable standalone single executable (Windows x64), reports 1.2.0.
• Linux binary: build on your box with cargo build --release (this release was cut from Windows, no Linux linker available here).

Quick Start:

gpu-smi-windows-x64.exe --serve 8080                          # loopback, no auth (unchanged)
openssl rand -hex 32 > token.txt                              # see example.env for full setup
gpu-smi-windows-x64.exe --serve 8080 --listen 0.0.0.0 --token-file .\token.txt
curl -H "Authorization: Bearer $(cat token.txt)" http://<host>:8080/metrics

gpu-smi v1.1.0 - VRAM Usage, OS Pinned VRAM & Process Tracking

gpu-smi v1.1.0 - Dedicated VRAM, OS Pinned Memory & Process Tracking

Major feature update bringing live dedicated VRAM utilization, OS pinned memory reporting, and per-process GPU tracking directly into the base output table.

What's New in v1.1.0:

• Per-Process GPU & VRAM Tracking: Real-time discovery and attribution of all GPU workloads (PID, Name, Type C/G, Memory Usage) using native Windows WDDM PDH counters mapped to hardware adapter LUIDs. Zero admin privileges or external tools required.
• Dedicated VRAM Usage: Live dedicated VRAM consumption (BytesResident) alongside total adapter memory and percentage utilization directly in the base table.
• OS Pinned VRAM: Non-evictable kernel driver & display compositor pinned memory calculation (BytesResident - BytesCommitted).
• Prometheus Metrics: Added amd_gpu_process_mem_mb and amd_gpu_vram_pinned_mb to the /metrics endpoint on --serve <PORT>.
• JSON Output: Fully serialized processes array with PIDs, names, types, and usage for programmatic scripting and tooling.

Downloads:

• gpu-smi-windows-x64.exe (1.0MB) - Portable standalone single executable (Windows x64).
• gpu-smi-linux-x64 (963KB) - Portable standalone single executable (Linux x64).

Quick Start:

gpu-smi-windows-x64.exe            # table with GPU stats & running processes
gpu-smi-windows-x64.exe --verbose  # show all processes + VRM/hotspot temps & clock rates
gpu-smi-windows-x64.exe --json     # full JSON output
gpu-smi-windows-x64.exe --serve 8080 # headless HTTP & Prometheus /metrics

gpu-smi v1.0.0 - portable single-exe for AMD

gpu-smi v1.0.0 - first release

Portable single-exe GPU SMI for AMD GPUs (Windows+Linux). AMD-compatible, unofficial.

Download: gpu-smi-windows-x64.exe (1.0MB) - just run, no installer, no ROCm SDK required.

Quick start:
gpu-smi-windows-x64.exe # table gpu-smi-windows-x64.exe --watch 1 # realtime gpu-smi-windows-x64.exe --json # JSON pipe gpu-smi-windows-x64.exe --serve 8080 # headless HTTP: curl http://127.0.0.1:8080/

Features:

• Auto-discovery HIP (TheRock) -> ADL PMLog (temps/clocks/power/util) -> WMI -> sysfs
• VRAM type autodetect DDR5/DDR4/LPDDR/GDDR5/HBM2/GDDR6 (not hardcoded)
• --watch realtime, --serve headless API (GET / JSON, GET /metrics Prometheus)
• Memory-safe Rust, self-contained (kernel32+VCRUNTIME140 only)
