Subject: STGI #UD exception
Date: Tue, 19 Jun 2007 19:45:57 -0700 (PDT) [thread overview]
Message-ID: <11206287.post@talk.nabble.com> (raw)
Hello all,
AMD manual states about STGI instruction:
"This instruction generates a #UD exception is SVM is not enabled."
However, if I execute in ring-0 the STGI instruction in my system with
EFER.SVME == 0, I receive a #GP exception instead of a #UD exception.
In other test, I just set the SVME bit to 1 and now I receive a #UD
exception!
Is the manual wrong?
P.S.: My CPU obviously has the SVM extensions (AMD X2 4600+ AM2)
