hi, list How can I disable interrput like `cli' in x86? I want the following code freeze the box but it doesn't, $MSR is altered however the box is still alive, how can I freeze the box like `cli' in x86? Thanks very much!
static
void cli(void)
{
unsigned long msr;
__asm__ __volatile__("": : :"memory");
msr = mfmsr();
printk("msr: 0x%lx\n", msr);
__asm__ __volatile__("sync" : : :"memory");
__asm__ __volatile__("wrteei 0" : : :"memory");
msr = mfmsr();
printk("msr: 0x%lx\n", msr);
printk(KERN_EMERG"!!msr: 0x%lx\n", msr);
}
P.S: the box is BOOKE compatible, the printk has shown is altered!
Regards,
Wang
