历史上,设备的 major number 采用的是注册制,各设备厂家在http://www.lanana.org/中注册他们的设备所使用的 major number。从http://www.lanana.org/docs/device-list/devices-2.6+.txt中还可以看出来 linux 2.6 内核中所分配的静态major numbers。 但是,现在,这个注册网站已经没有人维护了,取而代之的是动态...
从http://www.lanana.org/docs/device-list/devices-2.6+.txt中还可以看出来 linux 2.6 内核中所分配的静态major numbers。 但是,现在,这个注册网站已经没有人维护了,取而代之的是动态分配制度。分配者是linux 内核的 udev 模块。它将保证在本系统中,<major number>:<minor number>的组合是唯一的,而在这个范...

(Notice that you can work with the disk through the filesystem as well as directly through the disk devices. You’ll do both in this chapter.) 为了访问磁盘上的数据,Linux内核使用了图4-2所示的层次系统。 SCSI子系统和3.6深入解析:SCSI和Linux内核中描述的其他内容都由一个单独的框表示。 (请注意...
