[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~

Makefile文件,负责编译全过程

>_<" 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~

 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

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!

 89 ;1) 这个函数用来指定的段上限和地址赋值给GDTR的48位寄存器,这是个很特殊的寄存器,并不能用MOV来直接赋值
 90 ;,唯一的方法就是指定一个内存地址,从指定的内存地址读取6字节(也就是48位),然后赋值给GDTR寄存器。完成这一任务的指令就是LGDT
 91 ;2) 该寄存器的低16位(即内存的最初的2个字节)是段上限,它等于“GDT的有效的字节数-1”,剩下的32位,代表GDT的开始地址
 92 ;3) 这里2个参数是ESP+4和ESP+8里存放,而我们要的是6字节形式的,所以要转换为我们想要的形式~

143         POP        EAX
144         POPAD
145         POP        DS
146         POP        ES
147         IRETD
naskfunc.nas

PS: 一些不能用c语言来完成的函数还得用汇编,于是就都放在这个文件里了~

 


 

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~

PS: 该系统的内存分布图:在文件asmhead.nas有详细注释

147 ;内存分配:
148 ; 0x00000000-0x000fffff:虽然在启动中会多次使用,但之后就会变空(1M)
149 ; 0x00100000-0x00267fff:用于保存软盘的内容(1440KB)
150 ; 0x00268000-0x0026f7ff:空(30KB)
