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
[root@mxd mxd]# lspci -vvv -s 07:00.0 2>/dev/null | grep driver -A 2Kernel driver in use: 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
[root@mxd mxd]# lsmod | grep radeon
radeon 1687552 74
drm_suballoc_helper 49152 2 amdgpu,radeon
drm_ttm_helper 49152 2 amdgpu,radeon
ttm 131072 3 amdgpu,radeon,drm_ttm_helper
drm_display_helper 229376 2 amdgpu,radeon
