There is support in the x86 emulator to handle UMIP correctly in the case that it is found set in CR4. However, the logic to emulate UMIP on non-UMIP-capable hardware has not been merged yet. As for unit tests, if you use http://xenbits.xen.org/gitweb/?p=xtf.git;a=blob;f=tests/cpuid-faulting/main.c;hb=HEAD as an example, making a unit test should hopefully be trivial. General docs can be found here http://xenbits.xen.org/docs/xtf/ and 'd be happy to answer any other questions you have on XTF, should you choose to use it. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
