AMDGPU_TOP

amdgpu_top is tool that display AMD GPU utilization, like umr or clbr/radeontop or intel_gpu_top.
The tool displays information gathered from performance counters (GRBM, GRBM2), sensors, fdinfo, and AMDGPU driver.

Simple TUI (like nvidia-smi, rocm-smi)	TUI	GUI

Usage

cargo run -- [options ..]

Option

FLAGS:
   -d, --dump
       Dump AMDGPU info (Specifications, VRAM, PCI, ResizableBAR, VBIOS, Video caps)
   --list
       Display a list of AMDGPU devices (can be combined with "-d" option)
   -J, --json
       Output JSON formatted data
   --gui
       Launch GUI mode
   --smi
       Launch Simple TUI mode (like nvidia-smi, rocm-smi)
   -h, --help
       Print help information

OPTIONS:
   -i <u32>
       Select GPU instance
   --pci <String>
       Specifying PCI path (domain:bus:dev.func)
   -u <u64>, --update-process-index <u64>
       Update interval in seconds of the process index for fdinfo (default: 5s)

Commands for TUI

key
f	toggle fdinfo
n	toggle Sensors
m	toggle GPU Metrics
h	change update interval (high = 100ms, low = 1000ms)
q	Quit
P	sort fdinfo by pid
M	sort fdinfo by VRAM usage
G	sort fdinfo by GFX usage
M	sort fdinfo by MediaEngine usage
R	reverse sort
