This should be #define cpu_has_ept_ad (vmx_ept_vpid_cap & VMX_EPT_AD_BIT) put next to the respective other ones in vmx.h. > @@ -1150,6 +1152,9 @@ int ept_p2m_init(struct p2m_domain *p2m) > p2m->memory_type_changed = ept_memory_type_changed; > p2m->audit_p2m = NULL; > > + /* Work around Errata AVR41 on Avaton processors. */ > + cpu_has_ept_ad = boot_cpu_data.x86_model != 0x4d; And this one then should turn off said flag (i.e. needs to be moved elsewhere).
