interesting stuff. i wonder how much of the issue is that the rings 2/3
are supposed to be gone from EM64T, as the article says:
In practice, only rings 0 and 3, the highest and lowest, are
commonly used. OSes typically run in ring 0 while user programs
are in ring 3. One of the ways the 64-bit extensions to x86 ''clean
up'' the ISA is by losing the middle rings, 1 and 2. Pretty much no
one cared that they are gone, except the virtualization folk.
seems like solution is to skip plain EM64T and go to VT enabled EM64T with
-1 ring.
and there''s still no word from AMD on what they got?
finally, part 4 not mentioned in the above links
