A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.-A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running comput

扩展的动态内存机制 任务综述 本任务扩展了自己私有的内存管理机制。首先使用预先规划的思想，使用预先分配的内存池和内存分区，再通过使用消息队列作为内存池的管理机制处理内存块分配与释放的过程，而消息队列中保存的是每个预先申请内存块的地址。当用户需要分配一个内存块时，使用msgQReceive() 函数从消息队列中获取一个相应大小的内存块地址；当用户需要释放一个内存块时，则使用msgQSend()函数将内存块首地址发送回消息队列中。通过这种方法，减少了内存反复申请与释放产生外部碎片的可能，并能够有效利用预先分配的思想减少内部碎片。同时也通过消息队列的特性实现了方便的内存块申请与释放的管理操作。 同时，本系统作为扩展的动态内存管理机制，引入了定制的内存分配与释放功能，使用了互斥机制保证操作安全性和一系列告警机制。在保证内存分配与释放安全有序的基础上，还增加了管理监视机制。 其系统具体实现参照系统实现部分。-none
