Subject: [PATCH v3 15/18] hw/i386: Introduce apic_id_from_topo_ids handler in PCMachineState
Date: Tue, 03 Dec 2019 18:38:39 -0600 [thread overview]
Message-ID: <157541991943.46157.2185735998555897830.stgit@naples-babu.amd.com> (raw)
In-Reply-To: <157541968844.46157.17994918142533791313.stgit@naples-babu.amd.com>
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.
