[Xen-users] Does IDTR value changes in Guest Domians???

[Lakshman Jayaraju <Chethu2288@xxxxxxxxx>]

Hi All,
AM trying to fetch the IDT(Interrupt Descriptor Table) Base address using
the following program in domU PV Guest.

#include<linux/init.h>
#include<linux/kernel.h>
#include<linix/module.h>

MODULE_LICENSE("GPL");

static inline void *sidt(void)
{
        unsigned int ptr[2];
        __asm__ volatile ("sidt (%0)": : "a"(((char *) ptr)+2));
        retrun (void *) ptr[1];
}

static int __init hello_init(void)
{
        printk(KERN_INFO "%p",sidt());
        printk(KERN_INFO "Hello World!!!\n");
        return 0;
}

static void __exit hello_cleanup(void)
{
        printk(KERN_INFO "Cleaning up the module!!!\n");
}

module_init(hello_init);
module_exit(hello_cleanup);

On every insmod of this module, its displaying different base address. But
limit remains the same(i.e., 255)
Is this usual??? Or Is my program logic wrong???

Regards,
Lakshman Jayaraju
