This series fixes couple of issues with recent topology related code. 1. Modify AMD topology to use socket/dies/core/thread model
2. Error out if the user does not pass the dies information if EPYC cpu is numa configured. 3. Remove the node_id references in topology and use die_id instead. 4. With node_id removed in topology the uninitialized memory issue with -device and CPU hotplug will be fixed. Link: https://bugzilla.redhat.com/show_bug.cgi?id=1828750 --- v4: Not much of a change. Just added few text changes. Error out configuration instead of warning if dies are not configured in EPYC. Few other text changes to clarify the removal of node_id, nr_nodes and nodes_per_pkg. v3: https://lore.kernel.org/qemu-devel/159681772267.9679.1334429994189974662.st...@naples-babu.amd.com/#r Added a new check to pass the dies for EPYC numa configuration. Added Simplify CPUID_8000_001E patch with some changes suggested by Igor. Dropped the patch to build the topology from CpuInstanceProperties. TODO: Not sure if we still need the Autonuma changes Igor mentioned. Needs more clarity on that. v2: https://lore.kernel.org/qemu-devel/159362436285.36204.986406297373871949.st...@naples-babu.amd.com/ - Used the numa information from CpuInstanceProperties for building the apic_id suggested by Igor. - Also did some minor code re-aarangement to take care of changes. - Dropped the patch "Simplify CPUID_8000_001E" from v1. Will send it later. v1: https://lore.kernel.org/qemu-devel/159164739269.20543.3074052993891532749.st...@naples-babu.amd.com Babu Moger (3): i386: Simplify CPUID_8000_001E for AMD hw/i386: Update the EPYC topology to use socket/dies/core/thread model hw/i386: Remove node_id, nr_nodes and nodes_per_pkg from topology hw/i386/pc.c | 1 - hw/i386/x86.c | 9 ++++- include/hw/i386/topology.h | 40 +++++--------------- target/i386/cpu.c | 86 +++++++++++++++++++------------------------- target/i386/cpu.h | 1 - 5 files changed, 55 insertions(+), 82 deletions(-) --
