amdgpu_top 命令

常用示例

说明

amdgpu_top is an AMD GPU monitoring tool that displays real-time utilization data similar to htop but specifically for AMD graphics hardware. It gathers information from performance counters (GRBM, GRBM2), sensors, fdinfo, and the AMDGPU driver to provide comprehensive GPU metrics. The tool offers three display modes: a full-featured TUI (default), a simplified SMI-style TUI, and a graphical interface. It monitors GPU activity, VRAM usage, temperature, power consumption, fan speed, and per-process GPU utilization.

参数

-d, --dump

Dump AMDGPU info including specifications, VRAM, PCI, ResizableBAR, VBIOS, and video caps.

--list

Display a list of available AMDGPU devices.

-J, --json

Output JSON formatted data. Can be combined with the -d or --gpu-metrics option.

--gui

Launch graphical interface mode.

--smi

Launch simple TUI mode similar to nvidia-smi or rocm-smi.

-p, --process

Dump all GPU processes and memory usage per process.

-i _INDEX_

Select GPU instance by index number.

--pci _PATH_

Specify PCI path in domain:bus:dev.func format.

--apu, --select-apu

Select APU instance.

--single, --single-gpu

Display only the selected APU/GPU.

--no-pc

Disable reading performance counters (GRBM, GRBM2). Useful to avoid deactivating power saving features.

-gm, --gpu_metrics, --gpu-metrics

Dump gpu_metrics for all AMD GPUs.

--pp_table, --pp-table

Dump power/performance table from sysfs and VBIOS for all AMD GPUs.

--drm-info

Dump DRM information.

--json_fifo, --json-fifo _PATH_

Output JSON formatted data to a FIFO (named pipe) for other applications and scripts.

--decode-gm, --decode-gpu-metrics _PATH_

Decode the specified gpu_metrics file.

-s _MS_

Set refresh interval in milliseconds for JSON mode (default: 1000ms).

-n _COUNT_

Set maximum iteration count for JSON mode (0 = infinite).

-u, --update-process-index _SEC_

Update interval in seconds for fdinfo (default: 5s).

--dark, --dark-mode

Enable dark mode for TUI/GUI.

--light, --light-mode

Enable light mode for TUI/GUI.

--gl, --opengl

Use OpenGL API for GUI backend.

--vk, --vulkan

Use Vulkan API for GUI backend.

-V, --version

Print version information.
