Someone said Xen can have different CS values, but looking at the source it seems it's using the same ones, at least with a Linux hypervisor. So perhaps it was KVM. Looking at the header it seems paravirtualisation uses different cs values. On the upside, it seems we can just use that user_64bit_mode() to know whether it is 32 or 64 bit mode, so adding a bit telling the process mode is easier than I thought. Currently there is a need to tell if the 32 or 64-bit syscall path is being taken, which is independent of the process mode. > At minimum, we need a bit in CS for GDB.
