Hi Chris,

Apologies, I missed this when it went out (I'm even worse at reading
-discuss than I am -devel).

I am also interested in this, and my team will need to start working
on this soon unless someone has something already in the pipeline and
are willing to share it with the world.

Best Regards,

Leif

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:

https://gitlab.com/bwidawsk/qemu/-/tree/cxl-2.0v4

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

Best Regards,
Chris Browy
