Shuo A Liu 3110e70d0a hv: nested: INVEPT emulation supports shadow EPT ... L1 VM changes the guest EPT and do INVEPT to invalidate the previous TLB cache of EPT entries. The shadow EPT replies on INVEPT instruction to do the update. The target shadow EPTs can be found according to the 'type' of INVEPT. Here are two types and their target shadow EPT, 1) Single-context invalidation Get the EPTP from the INVEPT descriptor. Then find the target shadow EPT. 2) Global invalidation All shadow EPTs of the L1 VM. The INVEPT emulation handler invalidate all the EPT entries of the target shadow EPTs.
