Subject: RE: [PATCH V4 00/31] x86/sgx and selftests/sgx: Support SGX2

Hi Jarkko,

I am working on enabling Gramine with this EDMM patch series. I had tested with V2 patch series and it looked fine. Will evaluate Gramine with V4 patch series and post my updates in a couple of days.

Regards,
-Vijay
