用Qemu模拟vexpress-a9 （六） --- 多核

环境介绍

Win7 64 + Vmware 11 + ubuntu14.04 32

u-boot 版本：u-boot-2015-04

Linux kernel版本：linux-3.16.y

busybox版本：1_24_stable

交叉编译工具链：arm-linux-gnueabi-

qemu版本：stable-2.4

不带图形界面

qemu-system-arm \
    -M vexpress-a9 \
    -m 512M \
    -kernel /root/tq2440_work/kernel/linux-stable/out_vexpress_3_16/arch/arm/boot/zImage \
    -nographic \
    -append "root=/dev/mmcblk0  console=ttyAMA0" \
    -sd /root/tq2440_work/busybox_study/a9rootfs.ext3 \
    -smp 

起来后可以看一下它的cpuinfo
