Newer AMD CPUs also allow masking CPUID leaf 6 ECX and CPUID leaf 7 sub-leaf 0 EAX and EBX. Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx <mailto:jbeulich@xxxxxxxx>> TBD:- Fam15M0x is documented to not have MSR C0011002 despite CPUID[7,0].EBX != 0 from model 02 onwards, and contrary to what I see on the system I have access to (which is model 02) - Fam12, Fam14, and Fam16 are documented to not have MSR C0011003 despite CPUID[6].ECX != 0 Fam10 too has cpuid[6].ecx != 0 but no MSR C0011003 - Fam11 is documented to not even have MSR C0011004 and C0011005 I am still trying to get some clarity on this; Shall let you know soon :) -Aravind. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
