Yes, although I don't see much incremental benefit to developers publishing a root only raw table given it needs to be parsed along with all the other cxl information in the system. So, not opposed to the patch, but I want to direct you to the sysfs representation of the CEDT and CFMWS in /sys/bus/cxl/devices is what the cxl tool and libcxl library [1] will be using instead of the raw table. Platform firmware CXL details are modeled as "CXL root" objects in the /sys/bus/cxl device model. [1]: https://github.com/pmem/ndctl/tree/main/cxl
