（十三）r18 cpu id

1、cpuid内核接口

lichee/linux-4.4/drivers/soc/sunxi/sunxi-sid.c

int sunxi_get_soc_chipid(u8 *chipid)

int sunxi_get_serial(u8 *serial)

2、cpuid应用层接口

lichee/linux-4.4/drivers/char/sunxi-sysinfo/sunxi-sysinfo.c

static ssize_t sys_info_show(struct class *class,
struct class_attribute *attr, char *buf)

cat /sys/class/sunxi_info/sys_info 

sunxi_platform : sun50iw1
sunxi_secure : normal
sunxi_chipid : 240f080b503441100000940000000000
sunxi_chiptype : 000000bc
sunxi_batchno : 0x1
