Hello, I am interested in finding understanding how xen handles CPUID faulting and VM exits in general. Please can someone indicate to me the concerned files?
I want to know how xen detects the execution of the CPUID instruction and ensures a guest only gets the features defined in cpuid-autogen.h file depending on the guest type. I started looking at the file xen/arch/x86/cpuid.c but don't really know which other files to check next. Thanks Caleb
