X-Received-From: 192.55.52.93 Subject: [Qemu-devel] [PATCH v3 2/9] hw/i386: Adjust nr_dies with configured smp_dies for PCMachine X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Paolo Bonzini , "Dr . David Alan Gilbert" , like.xu@linux.intel.com Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" To support multiple dies configuration on PCMachine, the best place to set CPUX86State->nr_dies with requested PCMachineState->smp_dies is in pc_new_cpu() and pc_cpu_pre_plug(). Refactoring pc_new_cpu() is applied and redundant parameter "const char *typename" would be removed.
