Abstract
Implementations of the disclosure provide for supporting oversubscription of guest enclave memory pages. In one implementation, a processing device comprising a memory controller unit to access a secure enclave and a processor core, operatively coupled to the memory controller unit. The processing device is to identify a target memory page in memory. The target memory page is associated with a secure enclave of a virtual machine (VM). A data structure comprising context information corresponding to the target memory page is received. A state of the target memory page is determined based on the received data structure. The state indicating whether the target memory page is associated with at least one of: a child memory page or a parent memory page of the VM. Thereupon, an instruction to evict the target memory page from the secure enclave is generated based on the determined state.
