Hi, Inside an enclave I have data that I know will be reused frequently and would like to avoid EPC page eviciton. Is there a way to pin EPC pages and keep them away from the paging process?

Hello Kai,

Paging of the EPC is handled by the OS under the hood. There is no SGX-specific method for pinning EPC pages. There are several discussions on the web on how to keep the OS from paging certain processes. You can experiment with these and see if they help.

Regards,
