[PATCH v18 112/121] KVM: TDX: Ignore setting up mce

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx>

Because vmx_set_mce function is VMX specific and it cannot be used for TDX.
Add vt stub to ignore setting up mce for TDX.
