Description

As the author of a current RFC patchset under review for supporting a Type2 CXL device, it is worth to summarize what has been discussed so far, the current status of the patchset and also other tangential concerns like full privacy or CXL/PCIe slot resets and restoring CXL registers.

CXL.cache needs also to be discussed with the goal of defining a roadmap or at least first steps towards fully support, likely starting with security for restricting what a CXL.cache capable device can do. I will present a template for trying to define those goals.
