Subject: [Qemu-devel] [RFC 2 PATCH 14/16] hw/i386: Introduce epyc mode function handlers
Date: Fri, 6 Sep 2019 19:13:16 +0000
Message-ID: <156779719472.21957.5262347241826039177.stgit@localhost.localdomain> (raw)
In-Reply-To: <156779689013.21957.1631551572950676212.stgit@localhost.localdomain>

Introduce following handlers for new epyc mode.
x86_apicid_from_cpu_idx_epyc: Generate apicid from cpu index.
x86_topo_ids_from_apicid_epyc: Generate topo ids from apic id.
x86_apicid_from_topo_ids_epyci: Generate apicid from topo ids.
