Hi,

We’ve working with patch series on top of the QEMU CXL 2.0 Type 3 adding Data Object Exchange (DOE) for CDAT and Compliance Mode. This is required to support CXL 2.0 device enumeration and setup of SRAT/HMAT tables for OS handoff.

Based on QEMU version:

Do you have a roadmap for edk2 support for CXL 2.0? This is the last piece of the puzzle!

Best Regards,
