DSP Monitor Deployment

Introduction

DSP Monitor is a tool for monitoring DSP performance, helping users understand the real-time operating status and performance metrics of the DSP.

Supported Platforms

Platform	Running Method
IQ9075	Ubuntu 24.04

Prerequisites

1. IQ9075 hardware

2. Ubuntu 24.04 system

System Dependency Configuration

Configure the AidLux Repository

# Download the correct public key
sudo wget -O- https://archive.aidlux.com/ubuntu24/public.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/private-aidlux.gpg > /dev/null

# Edit the source file
sudo vim /etc/apt/sources.list.d/private-aidlux.list

# Add the private key provided by AidLux to the source file
deb [arch=arm64 signed-by=/etc/apt/trusted.gpg.d/private-aidlux.gpg] https://archive.aidlux.com/ubuntu24 noble main

# Update the cache
sudo apt update

After the update, you can obtain the official AidLux SDK dependencies with the following command:

sudo apt list | grep aid | grep unknown

# Install software
# Must be installed first; not included with the system
sudo apt install python3 python3-pip libopencv-dev python3-opencv  net-tools
# Required before installing aidlite
sudo apt install aidlux-aistack-base aidrtcm

# Install aidlite and its dependencies
sudo apt install aid-lms aidlms-sdk aidlite-sdk cmake
sudo apt-get install libfmt-dev nlohmann-json3-dev
sudo apt install aidlite-*

# Enable DSP support
sudo apt-get install qcom-fastrpc1
sudo apt-get install qcom-fastrpc-dev

# Install the aidgen SDK
sudo apt install aidgen-qnn240-sdk

# Install the mms service
sudo apt install aid-mms

# Enable GPU support
sudo apt-add-repository -s ppa:ubuntu-qcom-iot/qcom-ppa
sudo apt install qcom-adreno-cl1
sudo ln -s /usr/lib/aarch64-linux-gnu/libOpenCL.so.1 /usr/lib/aarch64-linux-gnu/libOpenCL.so

After installation, check that the aidlite and aidgen directories have been added under /usr/local/share.

Device Authorization

Obtain the Device SN Code

cat  /sys/devices/soc0/serial_number

Obtain the License File

Provide the SN code to the Aplux technical staff to generate a device-specific License file, and place it under /etc/opt/aidlux/license/AidLuxLics.

Activate Authorization

sudo /opt/aidlux/cpf/aid-lms/manager.sh restart

DSP Monitor Installation and Usage

sudo apt install aplux-aistack-dsp-monitor-v73

After installation, you can start the DSP Monitor service with the following command:

# npu 0
dsp_mon --all --cdsp_index 0
# npu 1
dsp_mon --all --cdsp_index 1

After startup, the system displays the current DSP performance metrics and operating status:

# npu 0
dsp arch: V73
dsp current freq: 921.599976 (MHz), current sample time(ms): 1001.742981
qdsp6 utilization: 0.449458 (%)
hvx utilization: 0.000000 (%)
hmx utilization: 0.000000 (%)

# npu 1
dsp arch: V73
dsp current freq: 921.599976 (MHz), current sample time(ms): 1001.710022
qdsp6 utilization: 0.445005 (%)
hvx utilization: 0.000000 (%)
hmx utilization: 0.000000 (%)
