From 00e66e37af0090f9ed95ca4bc3d8f5c6171daaf0 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Mon, 4 Jul 2022 11:16:04 +0100 Subject: [PATCH] arch_topology: Warn that topology for nested clusters is not supported We don't support the topology for clusters of CPU clusters while the DT and ACPI bindings theoritcally support the same. Just warn about the same so that it is clear to the users of arch_topology that the nested clusters are not yet supported.
