5.1 详细查看某pci设备使用的驱动 其中07:00.0是上面左侧显示的一段数字, 根据描述, 07:00.0那一行指一个VGA兼容设备, 换句话说是指显示设备, 业内叫做显卡
如下, 该显卡使用的驱动是:radeon

6. 查看系统下某驱动是否加载 如下显示:
第1列：表示模块的名称，如radeon表示radeon模块。
第2列：表示模块的大小，如1687552表示radeon模块的大小为1687552字节。
第3列：表示依赖模块的个数，如74表示radeon有74个依赖模块。
第4列：表示依赖模块的内容, 如drm_suballoc_helper依赖于amdgpu,radeon俩模块
