X-Received-From: 192.55.52.115 Subject: [Qemu-devel] [PATCH v3 10/10] vl.c: Replace smp global variables with smp machine properties X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Peter Maydell , Eduardo Habkost , qemu-devel@nongnu.org, "Dr . David Alan Gilbert" , Alistair Francis , Igor Mammedov Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" The global smp variables in vl.c are completely replaced with machine properties. Form this commit, the smp_cpus/smp_cores/smp_threads/max_cpus are deprecated and only machine properties within MachineState are fully applied and enabled.
