BTW, I found a corner case in CXL numa node creation. Condition: 1) A UMA/NUMA system without SRAT, but with CEDT.CFMWS 2）Enable CONFIG_ACPI_NUMA Results: 1) acpi_numa_init: the fake_pxm will be 0 and send to acpi_parse_cfmws() 2）If dynamically create cxl ram region, the cxl memory would be assigned to node0 rather than a new node Confusions: 1) Is a numa system a requirement for CXL memory usage? 2) Should we forbid this situation by adding fake_pxm check and returning error in acpi_numa_init()? 3）Or we can add some kernel code to allow create these fake nodes on a system without SRAT?
