Hi Ben,
I am sorry to disturb you for consulting you a question, my question is how I can make CXL HDM 1G-size alignment, CXL specification defines HDM is 256M alignment.
From my understanding, BIOS will allocate HPA and build ACPI SRAT for CXL HDM, do we have any method to tell OS or BIOS to align HDM with 1G size?
I don't sure whether we can configure BIOS address allocation, but hope any your suggestion and help!
Thanks,
David
