Hi,
Now I want to implement some functions in other hypervisor, so I need to read
SP_usr and SP_svc in HYP mode. I know Xen has implemented this function. But I
use it with regs->sp_usr/svc to achieve this. But I don't know how to achieve
it. I have read the entry.S file and get the process to save the regs, but some
definition is not clear. I want to know if there is some asm command to achieve
this? Or do I need to switch the mode manually to read it?
Thanks and regards,
Harry
