[自制简单操作系统] 2、鼠标及键盘中断处理事件[PIC\GDT\IDT\FIFO]
1、大致介绍：
>_<" 大致执行顺序是：ipl10.nas->asmhead.nas->bootpack.c
PS: 这里bootpack.c要调用graphic.c、dsctbl.c、fifo.c、int.c实现功能，其中有些函数还必须汇编来写，所以单独写一个汇编文件naskfunc.nas,为了方便看全部函数和结构体，所以写一个bootpack.h来写一些结构体和函数声明~
>_<" 下面是编译图解：最终生成的haribote.img可放在软盘来启动电脑，加载操作系统~

>_<" 此外还需要一个make.bat的脚本程序，这样把相应的编译器和上面的文件放到对应的位置（参看Makefile文件），运行DOS窗口输入：make run就能直接编译，打包，导入，运行在虚拟机上了~为了在UE上调试方便，我把make run命令也写成了脚本.bat，这样可在UE中直接调试运行~

INSTRSET指令是为了386以后的LGDT,EAX,CR0 70 ; LGDT指令把随意准备的GDT读出来，对于这个暂定的GDT我们今后还要重新设定，然后将CR0这一特殊的32位寄存器的值带入EAX 71 ; 并将高位置0，低位置1，再将这个值返回给CR0,这就完成了模式转化，进入到不用颁的保护模式。 72 ; CR0是control register 0是一个非常重要的寄存器,只有操作系统才能操作它 73 ; protected virtual address mode 受保护的虚拟内存地址模式，在该模式下，应用程序不能随便改变段的设定，又不能使用操作系统的段。操作系统受CPU保护 74 ; 在保护模式中主要有受保护的16位模式和受保护的32位模式，我们要使用的是受保护的32位模式 75 ; 在讲解CPU的书上会写到，通过带入CR0而切换到保护模式时，马上就执行JMP指令。所以我们也执行这一指令。为什么要jmp呢？因为变成保护模式后，机器语言的解释发生变化， 76 ; CPU为了加快指令的执行速度而使用了管道(pipeline)这一机制，也就是说前一条指令还在执行时，就开始解释下一条甚至是再下一条指令，因为模式变了就要重新解释一遍，so.. 77 ; 而且在程序中，进入保护模式后，段寄存器的意思也变了(不是*16再加算的意思)，除了CS以外所有的段寄存器的值都从0x0000变成了0x0008.CS保持不变是因为CS如果变了就乱了 78 ; 所以只有CS要放到后面处理。这里的0x0008相当于gdt+1的段 79 80 [INSTRSET "i486p"] ;

memcpy(bootpack ,BOTPAK ,512*1024/4 );//从bootpack的地址开始的512kb内容复制到0x00280000号地去[512kb比bootpack.hrb大很多] 100 ; memcpy(0x7c00 ,DSKCAC ,512/4 );//从0x7c00复制512字节到0x10000000是将启动扇区复制到1MB以后的内存去，[启动区的0x00007c00-0x00007dff，125字节] 101 ;

PS: 负责显示模式及分辨率设置及从16位转换为32位保护模式，是c语言和汇编语言的桥梁，所以称为asmhead文件，执行到最后就转到bootpack.c的主函数

PS: 中断句柄函数，但是这些并不是中断真正入口，真正入口是对应汇编函数，这些函数只是对应汇编函数要调用的~这些函数包括鼠标中断和键盘中断，因为为了加速，所以要把收到的数据放进FIFO缓冲区，防止因为在中断中进行大量的处理而影响速度~

PS: 就是个简单的用数组的形式建立的FIFO循环链表，建议看一下那个经典的黑色的数据结构的书，上面讲的很好，甚至有自动增加大小的循环链表，这个数据结构主要用来存放鼠标和键盘的信息~

PS: 这就是个字库，对于硬件级工程，字库是必须的！为什么我们编辑器里选择字形时英文这么多，汉字这么少，是因为设计中文字库的人少，一方面劳动量大，另一方面没钱赚，所以我们有着丰富的书法文化却只有几个可怜的字形可以选择！

3、效果说明：
>_<" 这里已经实现了文字显示，鼠标显示，键盘和鼠标信息的读取，其中涉及的知识有：GDT,IDT,中断,FIFO,VRAM,字库等，最终效果如下：

PS: 最上面显示鼠标当前位置，第二行左边显示按键信息，右边lcr显示鼠标点击事件（如果左边被点击l就变大写L，其他相同道理），后面两个数据是鼠标此次移动距离~
