Re: [PATCH] proc: added ept_ad flag to /proc/cpuinfo

Thank you Thomas. I missed what I think is your fundamental point regarding duplication created by this patch between CPU feature bits and KVM's consumption of the IA32_VMX_EPT_VPID_CAP MSR. Should all the features in this MSR be exposed via CPU feature bits and should KVM consume only from there

[PATCH] proc: added ept_ad flag to /proc/cpuinfo

From: Peter Feiner The Intel Haswell architecture has an EPT feature whereby the access & dirty bits in EPT entries are updated without taking a guest exit. This patch adds the "ept_ad" flag to /proc/cpuinfo if this feature is available. Signed-off-by: Peter Feiner Signed-off-b
