Linux设备驱动程序，用途是虚拟一段内存空间为设备驱动程序空间，在此段空间实现读写设备驱动程序。-Linux device driver, uses a memory space for the virtual device driver space, space to achieve during this read-write device drivers.

实时虚拟内存操作系统 支持多硬件架构-Real time virtual memory operating system. Should support multiple hardware architectures. Now only i386 is supported. It uses a partitioned memory system and can have multiple virtual memory contexts. Development is done on Linux
