JOS Lab 2: Memory Management
The first component is a physical memory allocator for the kernel, so that the kernel can allocate memory and later free it. Your allocator will operate in units of 4096 bytes, called pages. Your task will be to maintain data structures that record which physical pages are free and which are allocated, and how many processes are sharing each allocated page. You will also write the routines to allocate and free pages of memory.
The second component of memory management is virtual memory, which maps the virtual addresses used by kernel and user software to addresses in physical memory. The x86 hardware memory management unit (MMU) performs the mapping when instructions use memory, consulting a set of page tables. You will modify JOS to set up the MMU page tables according to a specification we provide.

使用
使用-debug参数运行时跟普通程序一样，省略；运行和停止这个服务可以在NT服务管理器中进行，也可以使用控制台命令net shart/stop，如果你愿意增加一些代码，也可以直接启动。停止这个服务还可以使用系统托盘中的Exit菜单-use-debug parameters at runtime with the ordinary procedures, omitted; To stop the operation and services in NT service manager for, you can also use commands net shart/stop, and if you are willing to increase the number of code can also be launched directly. Stop this service can also use the system tray Exit menu
