Because currently I'm not in lab I don't know my hypervisor is 32b or 64 bit.
I'm working in a security project. for improve security of applications running in virtualized environment. I want to use the security instruction of AMD SVM named SKINIT.
because this instruction must run in ring0, I add a hypercall in xen and write my codes in my hypercall function.
The skinit instruction takes the physical address of a block as an input operand( in the eax register) and establish a secure execution environment for a software component(block)
I have a label in my hypercall function that is the start of my block. In order to use skinit I want grab the physical address of my label to save in eax register.
Thanks if anyone help me.
