X-Received-From: 192.55.52.115 Subject: [Qemu-devel] [PATCH v3 01/10] hw/boards: Add struct CpuTopology to MachineState 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+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP The cpu topology property CpuTopology is added to the MachineState and its members are initialized with the leagcy global smp variables. From this commit, the code in the system emulation mode is supposed to use cpu topology variables from MachineState instead of the global ones defined in vl.c and there is no semantic change.
