[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [RFC] event channels and xen callbacks
Hi,i'm currently playing a bit with event channels and hypervisor callbacks, and i find myself stuck because i miss some informations. Maybe you can give me some hints: on amd64 arch, i'd like to know about hypervisor callback: ie, stack layout when called by Xen, stack location in memory (is it using the TSS entry as hardware traps do?) and finally, about how HYPERVISOR_iret() expects to find the stack upon call (like when you used iret? or something else?). I may write a little paper or tutorial from i've learned and didn't found in Xen doc after i get a better view of the whole thing...
