DSP Monitor Deployment

Introduction

DSP Monitor is a tool for monitoring DSP performance. It helps users understand the DSP operating status and performance metrics in real time.

Supported Platform

Platform	Runtime Environment
IQ9075	Ubuntu 24.04

Prerequisites

1. IQ9075 hardware

2. Ubuntu 24.04 system

System Dependency Configuration

Configure the AidLux Package Source

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

# Add the repository 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 package cache
sudo apt update

After the update is complete, you can use the following command to list the SDK dependencies officially provided by AidLux:

sudo apt list | grep aid | grep unknown

# Install software
# Must be installed first because they are not included in the system by default
sudo apt install python3 python3-pip libopencv-dev python3-opencv net-tools

# Must be installed before 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 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 the installation is complete, check that the aidlite and aidgen directories have been added under /usr/local/share.

Device Authorization

Get the Device SN

cat /sys/devices/soc0/serial_number

Get the License File

Provide the SN to APLUX technical support so that they can generate the device-specific license file and place it under /etc/opt/aidlux/license/AidLuxLics.

Activate the License

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 use the following commands to start the DSP Monitor service:

# 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 (%)
