You are helping the user verify their OS is properly optimized for their GPU (AMD in Daniel's case).

Process

  1. Identify GPU

    • List GPUs: lspci | grep -E "VGA|3D"
    • Get detailed info: lspci -v -s $(lspci | grep VGA | cut -d" " -f1)
    • For AMD: rocm-smi or rocminfo

  2. Check GPU drivers

    For AMD (ROCm):

    • Check ROCm version: rocminfo | grep "Name:" | head -1
    • Check kernel module: lsmod | grep amdgpu
    • Check firmware: ls /usr/lib/firmware/amdgpu/
    • Verify driver: glxinfo | grep "OpenGL renderer"

    Verify correct driver is loaded:

    • Check Xorg/Wayland: glxinfo | grep -E "vendor|renderer"
    • Should show AMD/RADV, not llvmpipe (software rendering)

  3. Check compute support

    • ROCm installation: rocminfo
    • HIP runtime: hipconfig --version
    • Check device visibility: rocm-smi --showproductname
    • Verify compute capability

  4. Check required packages

    dpkg -l | grep -E "rocm|amdgpu|mesa"
    • Key packages for AMD:
      • rocm-hip-runtime
      • rocm-opencl-runtime
      • mesa-vulkan-drivers
      • mesa-va-drivers (for video acceleration)
      • libdrm-amdgpu1

  5. Verify hardware acceleration

    • VA-API: vainfo (should show AMD)
    • Vulkan: vulkaninfo | grep deviceName
    • OpenGL: glxinfo | grep "direct rendering"
    • OpenCL: clinfo | grep "Device Name"

  6. Check performance settings

    • GPU clock states: cat /sys/class/drm/card*/device/pp_power_profile_mode
    • Performance level: cat /sys/class/drm/card*/device/power_dpm_force_performance_level
    • Fan control: rocm-smi --showfan

  7. System configuration

    • Check user in video/render groups: groups $USER
    • Should include: video, render
    • If not: sudo usermod -aG video,render $USER

  8. Check for optimization opportunities

    • Latest drivers available?
    • Kernel parameters optimized?
    • Memory (BAR size) properly configured?
    • PCI-E link speed: lspci -vv | grep -A 10 VGA | grep LnkSta

  9. Suggest improvements

    • Update drivers if outdated
    • Install missing packages
    • Optimize kernel parameters in GRUB:
      • amdgpu.ppfeaturemask=0xffffffff (unlock all features)
      • amdgpu.dpm=1 (enable dynamic power management)
    • Enable ReBAR if supported

Output

Provide a report showing:

  • GPU model and details
  • Driver status (version, loaded correctly)
  • ROCm/compute support status
  • Hardware acceleration status (VA-API, Vulkan, OpenGL)
  • User group membership
  • Performance settings
  • Missing packages or configurations
  • Recommended optimizations
