我们重写了缓冲区，使其能进行键盘和鼠标的读取

效果地址：http://blog.csdn.net/ucan23/article/details/17111431点击打开链接

/* filename:    fifo.c
 * description: 包含了有关缓冲区的操作

 */


#include "bootpack.h"

#define FLAGS_OVERRUN		0x0001

void fifo32_init(struct FIFO32 *fifo, int size, int *buf)
{
	fifo->size = size;
	fifo->buf = buf;
	fifo->free = size;
	fifo->flags = 0;
	fifo->p = 0;
	fifo->q = 0;
	return;
}

int fifo32_put(struct FIFO32 *fifo, int data)
{
	/*向FIFO传送数据并保存*/
	if (0==fifo->free){
		/*溢出*/
		fifo->flags |= FLAGS_OVERRUN;
		return -1;
	}
	fifo->buf[fifo->p] = data;
	fifo->p ++;
	if (fifo->p == fifo->size){
		fifo->p = 0;
	}
	fifo->free --;
	return;
}

int fifo32_get(struct FIFO32 *fifo)
{
	/*从FIFO读取一个数据*/
	int data;
	if (fifo->free == fifo->size){
		/*缓冲区为空，没有数据*/
		return -1;
	}
	data = fifo->buf[fifo->q];
	fifo->q ++;
	if (fifo->q == fifo->size){
		fifo->q = 0;
	}
	fifo->free ++;
	
	return data;
}
int fifo32_status(struct FIFO32 *fifo)
{
	/*返回缓冲区中还有多少数据*/
	return (fifo->size - fifo->free);
}

键盘操作也做了相应的修改

/* filename:    keyboard.c
 * description: 包含了有关键盘的操作

 * date:        2013-12-01
 * version:     v1.0
 */


#include "bootpack.h"

struct FIFO32 *keyfifo;
int keydata0;

void inthandler21(int *esp)
{
	/*ps/2键盘中断*/
	//struct BOOTINFO *binfo = (struct BOOTINFO *) ADR_BOOTINFO;
	int data;
	io_out8(PIC0_OCW2, 0x61);
	data = io_in8(PORT_KEYDAT);
	
	fifo32_put(keyfifo, data+keydata0);
	/*if (keybuf.len<32){
		keybuf.data[keybuf.next_w] = data;
		keybuf.len ++;
		keybuf.next_w ++;
		if (keybuf.next_w == 32) {
			keybuf.next_w = 0;
		}
	}
	*/
	
	return;
}

void wait_KBC_sendready(void)
{
	for (;;){
		if (0==(io_in8(PORT_KEYSTA) & KEYSTA_SEND_NOTREADY)){
			break;
		}
	}
	return;
}

void init_keyboard(struct FIFO32 *fifo, int data0)
{
	keyfifo = fifo;
	keydata0 = data0;
	wait_KBC_sendready();
	io_out8(PORT_KEYCMD, KEYCMD_WRITE_MODE);
	wait_KBC_sendready();
	io_out8(PORT_KEYDAT, KBC_MODE);
	return;
}

注：凡是原来是fifo8（FIFO8）的地方都改为了fifo32(FIFO32)，因为我们的结构体的定义发生了变化

为了提供对高分辨率的支持我们修改了开机后系统的启动代码
