Subject: [Qemu-devel] [RFC 2 PATCH 13/16] machine: Add new epyc property in PCMachineState
Date: Fri, 6 Sep 2019 19:13:09 +0000
Message-ID: <156779718791.21957.9675425538561156773.stgit@localhost.localdomain> (raw)
In-Reply-To: <156779689013.21957.1631551572950676212.stgit@localhost.localdomain>

Adds new epyc property in PCMachineState and also in MachineState.
This property will be used to initialize the mode specific handlers
to generate apic ids.
