Subject: [Xen-devel] About TSS initialization when Xen booting.


         I have a doubt on the Tss initialization. In the function cpu_init(),t->rsp0 = get_stack_bottom().

#define get_stack_bottom()                      \

           ((unsigned long)&get_cpu_info()->guest_cpu_user_regs.es)

         But I can’t find where the guest_cpu_user_regs has been initialized. Anybody can help me?
