[ECOS] question about interrupt service?

[li hui]

I had tried to revise my code,but it still failed to
response interrupt! I set my mouse on com2, My code is
below, please give me some advice to let it run.

#include <pkgconf/system.h>
#include <cyg/infra/cyg_type.h>
#include <cyg/hal/hal_arch.h>
#include <cyg/infra/diag.h>
#include <cyg/hal/drv_api.h>
#include <pkgconf/net.h>
#include <cyg/kernel/kapi.h>
#include <cyg/io/tvga/tvga.h>
#include <stdlib.h>
#include <stdio.h>

#define MOUSE_BASE 0x300
#define MOUSE_IRQ  35

static int mouse_user=0;          /* User count */
static int mouse_dx=0;            /* Position changes
*/
static int mouse_dy=0;          
static int mouse_event=0;         /* Mouse hase moved
*/
static unsigned char mouse_buttons=0;

static cyg_handle_t     interupt_handle;
static cyg_interrupt    interupt_obj;

static cyg_drv_cond_t     mouse_wait;
static cyg_drv_mutex_t    mouse_lock;
static cyg_drv_mutex_t    cond_lock;

static void mouse_interupt(cyg_vector_t vector,
cyg_ucount32 count, cyg_addrword_t data);

static cyg_uint32  isr(cyg_vector_t
vector,cyg_addrword_t data)
{
	vga_setcolor(3);

	ticks++;
	//vga_drawpixel(20,20+ticks*5);
	cyg_interrupt_acknowledge(MOUSE_IRQ);
	return CYG_ISR_HANDLED|CYG_ISR_CALL_DSR ;
}

static int mouse_lookup()
{
	if (mouse_user++)
	{
		return 0;
	}
	/****************************/
	/*****omit request IRQ ******/
	/****************************/
	/******ecos IRQ**************/

    vga_setmode(G360x480x256);

	diag_printf("enter init\n");
	
	cyg_interrupt_create ( MOUSE_IRQ, 99, 0, isr,
mouse_interupt, &interupt_handle, &interupt_obj);
	cyg_interrupt_attach (interupt_handle);
	
	cyg_drv_interrupt_unmask (MOUSE_IRQ);
    HAL_ENABLE_INTERRUPTS();
	while(ticks<10)
	{}
	printf("I reach!\n");
	
	return 0;
}
static void mouse_interupt(cyg_vector_t vector,
cyg_ucount32 count, cyg_addrword_t data)
{
	//vga_setcolor(15);
	//vga_drawpixel(50,50+ticks*5);
         diag_print("in DSR\n);
}

int main()
{
	mouse_lookup();

         return 0;
}
