From 24f0692bfd41fd207d99c993a5785c3426762046 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 20 Oct 2022 16:54:55 -0700 Subject: ACPI: NUMA: Add CXL CFMWS 'nodes' to the possible nodes set The ACPI CEDT.CFMWS indicates a range of possible address where new CXL regions can appear. Each range is associated with a QTG id (QoS Throttling Group id). For each range + QTG pair that is not covered by a proximity domain in the SRAT, Linux creates a new NUMA node. However, the commit that added the new ranges missed updating the node_possible mask which causes memory_group_register() to fail. Add the new nodes to the nodes_possible mask.
