Intel Simics VMP内核在PopOS 22.04下编译安装失败求助

问题描述 #

在PopOS 22.04 LTS系统编译安装Intel Simics VMP内核模块时失败，核心报错为get_user_pages函数参数不匹配，具体报错信息如下：

================================================

This step will be performed with root privilege through sudo:

  - Loading of the vmxmon kernel module.

Unless this script is run as root, you will be prompted for the

系统环境信息：

• OS: PopOS 22.04 LTS
• Kernel: 6.5.6-76060506-generic
• CPU: Intel® Core™ i7-10850H CPU @ 2.70GHz × 12
• RAM: 32GB
• BIOS已启用所有Intel虚拟化技术
• 系统已更新至最新版本
• Simics版本：6.0.169（公开版）

可行解决办法 #

1. 降级内核到6.0以下版本 #

Linux 6.0+对get_user_pages函数签名做了修改，而Simics 6.0.169的vmxmon模块仅兼容旧版内核：

• 安装5.15系列LTS内核：sudo apt install linux-image-5.15.0-88-generic linux-headers-5.15.0-88-generic
• 重启后在GRUB菜单的「Advanced options for Pop!_OS」中选择5.15内核启动
• 重新运行Simics VMP安装脚本

2. 手动修改vmxmon代码适配新内核 #

修改/home/herget/simics/simics-6.0.169/vmxmon/build/module/linux/page.c中的get_upage函数：

• 找到第295行的get_user_pages调用，将其替换为内核6.0+兼容的函数（如get_user_pages_locked或get_user_pages_remote），调整参数匹配新函数签名
• 修改完成后，重新执行安装脚本：cd /home/herget/simics/simics-6.0.169 && ./setup-vmp.sh

3. 升级Simics到支持新内核的版本 #

Intel后续发布的Simics版本可能已适配Linux 6.x内核：

• 下载最新公开版或商业版Simics
• 卸载旧版本后安装新版本，再运行VMP安装脚本
