Re: CXL 2.0 Type 3 Support

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,

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!
