Hi,

I have read the article regarding paging support is not available in Windows SGX SDK. How about the Linux SGX SDK, whether paging support is available or not? Share the sample code path with me.

- Thanks

Hi Sam,

Yes, Linux driver supports paging, which allows the enclave to access the additional RAM via page swaps. The Windows kernel does not yet support this feature, so it is limited to ~90 MB.
