Avoiding asynchronous enclave exits based on requests to invalidate translation lookaside buffer entries
摘要
說明書
In Example S5, the subject matter of any one of Examples S1-54 can optionally include where the microcode is to further determine that the logical processor is running in the enclave mode and that one or more page addresses indicated by the RAR are within an enclave address range.
In Example S6, the subject matter of any one of Examples S1-55 can optionally include where the prior epoch is a period during which a prior value was assigned to a global epoch variable.
In Example S7, the subject matter of any one of Examples S1-56 can optionally include where the results indicate that the control and state pages associated with the enclave mode are unmodified, unblocked and otherwise accessible to the logical processor.
In Example S8, the subject matter of any one of Examples S1-57 can optionally include where the control page includes meta information related to a thread running on the logical processor.
In Example S9, the subject matter of any one of Examples S1-S8 can optionally include where at least one state page includes context information associated with a state of the logical processor.
In Example S10, the subject matter of any one of Examples S1-S9 can optionally include where the one or more variables include an enclave entry epoch variable and one or more enclave reference counters.
In Example S11, the subject matter of Example S10 can optionally include where adjusting the enclave entry epoch variable includes setting the enclave entry epoch variable to a current value of a global epoch variable.
