| Thread-topic: | One question on xen_cpuid in pv guest |
I have a question to xen_cpuid() in pv_ops guest. Currently the cpuid will be trapped to xen HV for emulation. So why do we still use cpuid_leaf1_edx_mask/cpuid_leaf1_ecx_mask to do mask in guest side? Havn't that been achieved in hypervisor already? Thanks Yunhong Jiang _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
