[microblaze-uclinux] Xilinux PS2 mouse driver

["Hema K" <hemak@xxxxxxxxxxxx>]

Hi !!!

I have a problem regarding the PS2 drivers from the which i got fron
Xilinx website
http://www.xilinx.com/products/boards/ml401/reference_designs.htm
in ML401 EDK Embedded MicroBlaze Reference Design zip file ,after unzipping in the path
projects/ml401_emb_ref/drivers/ps2_ref_v1_00_a/src$

this code id similar to the Xilinux Emac code,here they have a adapter.c file which has  Xilinx Ethernet Adapter component to interface XEmac component to Linux.

Similarly i want to write a adapter.c for my PS2 mouse,can anyone suggest me how to write it.
when i mailed to the xilinux wedsite  they asked me to get into this dicussion forum.

at present i have written this code.In the hyper terminal the output is "psmouse is mapped to the address 0xffff7000"

now can i initialize and write up the ISR routine 
similar to pc_keyb.c in uClinux-dist/linux-2.4.x/drivers/char/pc_keyb.c

can i use the same functions in pc_keyb.c to initialize and for the ISR.
i am confused in this part...can anyone give me suggestions in this 

following is the small bit of my adapter.c

static int __init
probe(int index)
{
        static const unsigned long remap_size
            = CONFIG_MOUSE_0_HIGHADDR - CONFIG_MOUSE_0_BASEADDR + 1;
        struct xps2_instance *inst;
        XPs2_Config *cfg;

        /* Find the config for our instance. */
        cfg = XPs2_GetConfig(index);
        if (!cfg)
                return -ENODEV;

        /* Allocate the inst and zero it out. */
        inst = (struct xps2_instance *) kmalloc(sizeof (struct xps2_instance),
                                                 GFP_KERNEL);
        if (!inst) {
                printk(KERN_ERR "%s #%d: Could not allocate instance.\n",
                       miscdev.name, index);
                return -ENOMEM;
        }
        memset(inst, 0, sizeof (struct xps2_instance));
        inst->index = index;

        /* Make it the head of inst_list. */
        inst->next_inst = inst_list;
        inst_list = inst;

        /* Change the addresses to be virtual; save the old ones to restore. */
        inst->save_BaseAddress = cfg->BaseAddress;
        cfg->BaseAddress = (u32) ioremap(inst->save_BaseAddress, remap_size);

        /* Tell the Xilinx code to bring this MOUSE interface up. */
        if (XPs2_Initialize(&inst->Ps2, cfg->DeviceId) != XST_SUCCESS) {
                printk(KERN_ERR "%s #%d: Could not initialize instance.\n",
                       miscdev.name, inst->index);
                remove_head_inst();
                return -ENODEV;
        }

        printk(KERN_INFO "%s #%d at 0x%08X mapped to 0x%08X\n",
               miscdev.name, inst->index,
               inst->save_BaseAddress, cfg->BaseAddress);

return 0
}





Thanks & Regards
