Мышь PS / 2 не стреляет

Каждый! Я только что закончил писать свой драйвер клавиатуры. Сейчас проблема в том, что мой PSQ / 2 MOQ IRQ не сработает (IRQ 12). Я проверил это с помощью этого кода:

    #include "irq.h"

,0,0,0,0,0,0,0,0
};

static SerialPort sp_irq;

//Basically a declaration of IDT_ENTRY in
//idt.c++
struct idt_entry {
uint16_t base_lo;
uint16_t sel; // Kernel segment goes here.
uint8_t always0;
uint8_t flags; // Set using the table.
uint16_t base_hi;
}__attribute__((packed));

//Get the Exact IDT array from idt.c++
extern struct idt_entry idt[256];

static inline void idt_set_gate(uint8_t num, void(*handler)(void), uint16_t sel,
uint8_t flags)
{
idt[num].base_lo = (uintptr_t)handler >> 0 & 0xFFFF;
idt[num].base_hi = (uintptr_t)handler >> 16 & 0xffff;
idt[num].always0 = 0;
idt[num].sel = sel;
idt[num].flags = flags;
}

IRQ::IRQ(){};
IRQ::~IRQ(){};

/* Normally, IRQs 0 to 7 are mapped to entries 8 to 15. This

*  what's happening. We send commands to the Programmable
*  Interrupt Controller (PICs - also called the 8259's) in

/* Each of the IRQ ISRs point to this function, rather than

*  are two 8259 chips: The first exists at 0x20, the second
*  exists at 0xA0. If the second controller (an IRQ from 8 to
*  15) gets an interrupt, you need to acknowledge the
*  interrupt at BOTH controllers, otherwise, you only send
*  an EOI command to the first controller. If you don't send
*  an EOI, you won't raise any more IRQs */
extern "C" void irq_handler(struct regs *r)
{
/* This is a blank function pointer */
regs_func handler;

/* Find out if we have a custom handler to run for this
*  IRQ, and then finally, run it */

if (handler)
{handler(r);
}

/* If the IDT entry that was invoked was greater than 40*  (meaning IRQ8 - 15), then we need to send an EOI to
*  the slave controller */
if (r->int_no >= 8)
{
p8b_irq.out(0x20,0xA0);
}

/* In either case, we need to send an EOI to the master
*  interrupt controller too */

как вы можете видеть внизу, где находится мой irq_handler, для каждого irq я говорю ему напечатать irq_number. Ну, я настроил свой PIT, поэтому я получаю 0 каждую секунду, а затем, так как я настраиваю свою клавиатуру, я получаю 1 каждый раз, когда я нажимаю клавишу. 4 в начале, потому что я включаю COM1. НО, когда я двигаю мою мышь, я не получаю 12 по какой-то причине … Мой драйвер мыши выглядит следующим образом:

mouse.c ++:

#include "mouse.h"

typedef void(*regs_func)(struct regs *r);

extern void install_handler_irq(int irq, regs_func handler);

static PORT::Port8Bits p8b_mouse_drv;void mouse_ps2_handler(struct regs *r)
{
printf("IRQ 12 \n ");
}
void mouse_wait(unsigned char type)
{
unsigned int _time_out=100000;
if(type==0)
{
while(_time_out--) //Data
{
if((p8b_mouse_drv.in(0x64) & 1)==1)
{
return;
}
}
return;
}
else
{
while(_time_out--) //Signal
{
if((p8b_mouse_drv.in(0x64) & 2)==0)
{
return;
}
}
return;
}
}

unsigned char mouse_read()
{
//Get response from mouse
mouse_wait(0);
return p8b_mouse_drv.in(0x60);
}void mouse_write(unsigned char a_write)
{
//Wait to be able to send a command
mouse_wait(1);
//Tell the mouse we are sending a command
p8b_mouse_drv.out(0xD4,0x64);
//Wait for the final part
mouse_wait(1);
//Finally write
p8b_mouse_drv.out(a_write,0x60);
}

void MOUSE::install_mouse_driver()
{
mouse_wait(1);
p8b_mouse_drv.out(0xA8,0x64);

mouse_wait(1);
p8b_mouse_drv.out(0x20,0x64);

unsigned char status_byte;
mouse_wait(0);
status_byte = (p8b_mouse_drv.in(0x60) | 2);mouse_wait(1);
p8b_mouse_drv.out(0x60,0x64);mouse_wait(1);
p8b_mouse_drv.out(status_byte,0x60);mouse_write(0xF6);
mouse_read();

mouse_write(0xF4);
mouse_read();

install_handler_irq(12, mouse_ps2_handler);
}
