Subject: [Qemu-devel] [RFC 2 PATCH 12/16] hw/i386: Introduce apic_id_from_topo_ids handler in PCMachineState
Date: Fri, 6 Sep 2019 19:13:02 +0000
Message-ID: <156779718115.21957.699621482515468870.stgit@localhost.localdomain> (raw)
In-Reply-To: <156779689013.21957.1631551572950676212.stgit@localhost.localdomain>

Add function pointer apic_id_from_topo_ids in PCMachineState.
Initialize with correct handler based on the mode selected.
Also rename the handler apicid_from_topo_ids to x86_apicid_from_topo_ids
for  consistency. x86_apicid_from_topo_ids will be the default handler.
