Hi all, I'm investigating Xen bootup sequence and I'm stuck with the function set_current((struct vcpu *)0xfffff000); the high level idea is that it is assigning VCPU to physical CPU but I can't understand the following 1) what is the need of this hard coded address? it is seemed that vcpu
exist on this address (but no idea who put vcpu on that particular
address)? (the same address is passed both in case of ARM and X86)
2) no idea about what exactly get_cpu_info() (called by set_current) is doing.. (logically doing & and or with sp register)? Thanks _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
