Re: [Xen-devel] RIP register value in p2m_mem_access_check()



I know close to nothing about the paths that can lead here, and
hence I can't assess whether expecting consistency at this point
is valid. All I can tell is that right after VM exit (i.e. at the top of
vmx_vmexit_handler()) the two values ought to be consistent.

Yes, that's true, however what I'm after is a way to have the information associated with the proper RIP _before_ the VM exit (basically all of the information that gets stuffed into the struct hvm_hw_cpu instance by xc_domain_hvm_getcontext_partial()). Specifically, I want that information inside p2m_mem_access_check().


Thanks for your help,
Razvan Cojocaru
