It seems to work for VMX (see the testcase I just sent). For SVM, can you
check if this test works for you, so that we can work on a simple testcase?
It passes for SVM, too.
However, npt_rsvd seems to be broken - maybe that is the reason?
Also, I tried to use different register values for npt_l1mmio_test() and
npt_l1mmio_check() (like 0xfee00030 and 0xfee00400), but got test passed
as well. Could it be a false positive then?
