MUSA 安装

概述

本指南涵盖 Linux Driver 和 MUSA SDK 在 MTT E300 的完整安装流程。

---

支持的硬件平台

本节列出 MUSA 安装支持的硬件平台。

设备型号

平台	型号
MTT E300	E300

操作系统

包管理	操作系统	版本
deb	Ubuntu	22.04
deb	AIOS	1.4.1

---

软件包下载

具体软件包下载信息如下所示：

软件包

包	驱动包
musa	musa_5.1.1-M1000_arm64.deb
musa-sdk	musa-sdk_5.1.1-M1000_arm64.deb

---

卸载旧版本（可选）

sudo dpkg -P musa musa-sdk
sudo rm -rf /usr/local/musa

---

安装

命令行安装

# musa
sudo dpkg -i musa_5.1.1-M1000_arm64.deb

# musa-sdk
sudo dpkg -i musa-sdk_5.1.1-M1000_arm64.deb

# 添加用户组
sudo usermod -aG render ${USER}
sudo usermod -aG video ${USER}

# 当前 shell 添加 MUSA envs（临时生效）
export PATH=/usr/local/musa/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/musa/lib:$LD_LIBRARY_PATH

# 永久生效（写入 ~/.bashrc）
echo 'export PATH=/usr/local/musa/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/musa/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc

安装后，重启操作系统使驱动加载：

sudo reboot

验证安装

步骤 1：验证 Linux Driver 安装

查看驱动模块是否加载：

命令：

lsmod | grep mtgpu

示例输出：

mtgpu                4579328  59
mt_ion                 49152  1 mtgpu
mdev                   24576  1 mtgpu
drm_display_helper    180224  2 mtgpu,mtdisp
drm_kms_helper        217088  5 mtgpu,drm_display_helper,mtdisp
drm                   643072  33 mtgpu,i2c_hid,drm_kms_helper,drm_display_helper,mtdisp

查看 Linux Driver 版本信息：

方式一命令：

dmesg | grep "Driver Version"

方式一示例输出：

[    5.321818] MTGPU Driver Version: fff6a5a-dirty release build for Desktop

方式二命令：

sudo cat /var/log/dmesg | grep "Driver Version"

方式二示例输出：

[    5.321818] kernel: MTGPU Driver Version: fff6a5a-dirty release build for Desktop

更多详情，参见 Linux Driver 文档

步骤 2：验证 MUSA SDK 安装

验证 MUSA Toolkit 是否安装成功：

命令：

musa_version_query

开启compute_only，关闭桌面（提高推理性能可选）

当设备用于推理任务时，可开启 compute_only 并关闭桌面服务，以减少图形显示相关资源占用。

操作步骤

1. 新建脚本 enable_compute_only.sh：

#!/usr/bin/env bash
set -euo pipefail

usage() {
  cat <<'EOF'
用法:
  sudo ./enable_compute_only.sh enable
  sudo ./enable_compute_only.sh disable
EOF
  exit 1
}

if [[ "${EUID}" -ne 0 ]]; then
  echo "请使用 sudo 运行该脚本"
  exit 1
fi

ACTION="${1:-}"
if [[ -z "${ACTION}" ]]; then
  usage
fi

case "${ACTION}" in
  enable)
    echo "[1/7] 写入 /etc/modprobe.d/mtgpu.conf"
    echo "options mtgpu mtgpu_drm_major=2 compute_only=1" > /etc/modprobe.d/mtgpu.conf

    echo "[2/7] 更新 initramfs"
    update-initramfs -u

    echo "[3/7] 禁用 gdm3"
    systemctl disable gdm3

    echo "[4/7] 停止 gdm3"
    systemctl stop gdm3

    echo "[5/7] 检查 xorg 进程"
    if pgrep -fa xorg >/dev/null; then
      echo "检测到 xorg 进程仍在运行，请先确认并停止后再重试："
      pgrep -fa xorg || true
      exit 1
    fi

    echo "xorg 进程检查通过（无 xorg 进程）"

    echo "[6/7] 重启设备前提示"
    echo "reboot 完成后，请执行以下命令检查："
    echo "  cat /sys/module/mtgpu/parameters/compute_only"
    echo "期望结果："
    echo "  - /sys/module/mtgpu/parameters/compute_only 输出为: 1"

    echo "[7/7] 重启设备"
    reboot
    ;;

  disable)
    echo "[1/5] 写入 /etc/modprobe.d/mtgpu.conf"
    echo "options mtgpu mtgpu_drm_major=2" > /etc/modprobe.d/mtgpu.conf

    echo "[2/5] 更新 initramfs"
    update-initramfs -u

    echo "[3/5] 配置 display-manager.service 指向 gdm.service"
    ln -sfn /lib/systemd/system/gdm.service /etc/systemd/system/display-manager.service

    echo "[4/5] 重载 systemd 并启动 display-manager.service"
    systemctl daemon-reload
    systemctl start display-manager.service

    echo "[5/5] 重启设备前提示"
    echo "reboot 完成后，请执行以下命令检查："
    echo "  cat /sys/module/mtgpu/parameters/compute_only"
    echo "期望结果："
    echo "  - /sys/module/mtgpu/parameters/compute_only 输出为: 0"

    echo "现在重启设备"
    reboot
    ;;

  *)
    usage
    ;;
esac

2. 添加执行权限：

chmod +x enable_compute_only.sh

3. 开启 compute_only（关闭桌面）：

sudo ./enable_compute_only.sh enable

4. 恢复桌面并关闭 compute_only：

sudo ./enable_compute_only.sh disable
