Subject: [RFC v2 02/12] qdev: Introduce new device category to cover basic topology device
Date: Thu, 19 Sep 2024 14:11:18 +0800	[thread overview]
Message-ID: <20240919061128.769139-3-zhao1.liu@intel.com> (raw)
In-Reply-To: <20240919061128.769139-1-zhao1.liu@intel.com>

Topology devices are used to define CPUs and need to be created and
realized earlier than current qemu_create_cli_devices().

Use this new catogory to identify such special devices, which allows
to create them earlier in subsequent change.
