udev属性是udev机制中的一种属性,用于描述和配置设备的特性和行为。 在udev中,键盘设备也可以通过udev属性进行配置。键盘的udev属性可以包括以下几个方面: 设备路径(devpath):键盘设备在系统中的路径,用于唯一标识设备。 设备名称(devname):键盘设备的名称,用于在系统中识别设备。 设备类型(devtype):键盘设备的类型,...
使用udev_monitor_filter_add_match_subsystem_devtype增加一个基于设备类型的udev事件过滤器,例如: "block"设备。 使用udev_monitor_enable_receiving启动监控过程。监控可以使用udev_monitor_get_fd获取一个文件描述符,基于返回的fd可以执行poll操作,简化程序设计。 插拔事件到达后,可以使用udev_monitor_receive_device获...

以device_add为起点,uevent事件被这样产生和传递: device_add => kobject_uevent(&dev->kobj, KOBJ_ADD) => /* send netlink message */ ... /* 准备参数 */ argv [0] = uevent_helper; argv [1] = (char *)subsystem; argv [2] = NULL; ...

blkid_log_get_value(log, "TYPE") udev_device_get_devnode(dev)); } As temporary solution I suggest to remove BLKID_SUBLKS_BADCSUM flag from udev. And while that isn't crucial I think it's actually kind of a nice feature to have... except that it doesn't work this way right now...
