# AMDGPU\_TOP
`amdgpu_top` is tool that display AMD GPU utilization, like [umr](https://gitlab.freedesktop.org/tomstdenis/umr/) or [clbr/radeontop](https://github.com/clbr/radeontop) or [intel_gpu_top](https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/blob/master/man/intel_gpu_top.rst).  
The tool displays information gathered from performance counters (GRBM, GRBM2), sensors, fdinfo, and AMDGPU driver.

## Usage
```
cargo run -- [options ..]
# or

```

```
# Run TUI mode
amdgpu_top

# Run GUI mode
amdgpu_top --gui

# Run SMI mode
amdgpu_top --smi

# Dump AMDGPU info
amdgpu_top -d

# Dump AMDGPU info and gpu_metrics
amdgpu_top -d -gm

# Dump AMDGPU info and pp_table
amdgpu_top -d --pp-table

```

### Options
```
FLAGS:
   -d, --dump
       Dump AMDGPU info. (Specifications, VRAM, PCI, ResizableBAR, VBIOS, Video caps)
       This option can be combined with the "-J" option.
   --list
       Display a list of AMDGPU devices.
   -J, --json

### fdinfo description
fdinfo for the AMDGPU driver shows hardware IP usage per process.

### VRAM
GPU Memory.

### GTT
Graphics Translation Tables.

### KFD
The process of using the AMDKFD driver.

#### GFX
GFX engine.

#### Compute/COMP
Compute engine.  
The AMDKFD driver does not track queues and does not show them in fdinfo.

#### DMA
DMA/SDMA (System DMA) engine.

#### Decode/DEC
Media decoder.  
This is not show on VCN4 or later.

#### Encode/ENC
Media encoder.  
This is not show on VCN4 or later.

#### VCN, Media
Media engine.  
From VCN4, the encoding queue and decoding queue have been unified.
The AMDGPU driver handles both decoding and encoding as contexts for the encoding engine.

This is the average of the video decoder/encoder and the JPEG decoder usage.

#### JPEG
JPEG decoder.

#### VPE
Video Processor Engine.  
ref: <https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/vpelib/README.md?ref_type=heads>

#### VCN_Unified, VCNU
