hw-smi v1.6

Fixes/improvements

• hw-smi now supports logging telemetry data to a file

  • run hw-smi with the --log command-line option
  • this will write all telemetry data into a file hw-smi-YYYY-DD-MM-hh-mm-ss.log located next to the hw-smi executable
  • the telemetry data in the file is formatted as follows:

• updated amdsmi.h to be compatible with latest AMD Linux GPU driver

How to run?

Windows

• Download hw-smi.exe or hw-smi-hud.exe (version with graphical on-screen HUD).
• Double-click (you will be asked to run as administrator, this is required for some Intel GPU counters).
• Alternatively, run in Windows CMD via

  hw-smi.exe
  hw-smi.exe --bars
  hw-smi.exe --graphs
  hw-smi.exe --log
  hw-smi.exe --help

• Or compile from source code on Windows

Linux

• Clone from GitHub:

  git clone https://github.com/ProjectPhysX/hw-smi.git && cd hw-smi

• Compile:

  chmod +x make.sh
  ./make.sh

• Run:

  sudo bin/hw-smi
  sudo bin/hw-smi --bars
  sudo bin/hw-smi --graphs
  sudo bin/hw-smi --log
  sudo bin/hw-smi --help

• Note that it will also work without sudo. However, some telemetry counters on Intel GPUs are not available without sudo.
