3.1 wifi 适配层代码框架结构分析
Wifi 配置整体框架图如下：
APP
无线接口层（WMI）
SDIO DRIVER
AR6003 devices
wlan无线接口层（wmi）向上给APP提供接口与wifiAR6003驱动通信，使得上层应用程序可以对wifi芯片进行适配，满足应用需求，向下通过sdio驱动向wifi芯片下发配置命令，配置wifi各项参数。
具体配置命令是通过sdio驱动来实现的，sdio驱动通过ioctl系统调用直接控制wifi AR6003芯片，向上层提供一堆的ioctl调用接口。为了管理这些接口
高通写了一个应用程序wmiconfig进程来管理这些系统调用命令。上层其他APP只需要调用wmiconfig进程通过传入不同的参数来实现对wifi的配置。Wmiconfig进程中会去解析其他APP传入的命令行参数，然后调用相应的ioctl系统调用。
Wmiconfig进程的代码框架结构如下：
――――――main（）：函数入口
――getopt_long（）：解析命令行参数 通过switch case结构处理所有命令分支，因为命令非常多，所以caase分支非常庞大。
－－ioctl（）：命令解析完成后，执行相应的系统命令调用，调用过程同样通过switch case来区分不同的调用分支。
图1
如图1所示，wmiconfig代码结构非常简单，解析参数，执行ioctl系统调用，调用完成函数退出。主要难点是理清各种不同的ioctl命令作用，只有充分了解这些系统调用的作用才能正确使用这些系统调用实现softAP的功能。
下面贴出AR6003芯片所有的ioctl配置命令：

以上25条wmiconfig命令为softap设计可能会用到的。可以供后续SoftAp设计参考。
3.3 Softap基本框架结构设计简介
Softap基本框架结构设计主要步骤如下：
一、加载wifi驱动：
方法：
1，使能sdio驱动
echo 1 > /sys/devices/platform/msm_sdcc.2/polling
2，使能ip转发功能
echo 1 > /proc/sys/net/ipv4/ip_forward
3，加载ar6000驱动模块，并且设置wifi模式为单AP模式
modprobe ar6000 targetconf=\"router\" devmode=ap
4，等待wifi驱动加载成功。
查看/proc/sys/net/ipv4/conf/eth0是否生成。
二、启动hostapd进程和dhcpserver进程
Hostapd进程是用来管理wifi的，dhcpserver进程是用来给lan侧地址分配地址使用的。
三、配置wlan接口
方法:
1，设置ssid名
Wmiconfig eth0 –ssid “ssidname”
2，使能wlan接口，并且为接口设置ip地址
ifconfig eth0 192.168.1.1 netmask 255.255.255.0up
四、去使能sdio驱动
echo 0 >/sys/devices/platform/msm_sdcc.2/polling
3.4 总结
通过以上五个步骤后，可以实现wifi基本功能的设置，其他一些功能模块可以通过上述3.2小节中的wmiconfig命令进行适配。Wifi提供给上层的sdk接口主要就是对wmiconfig命令的封装。前提是这些命令是可以正确运行的。
Wifi设计的主要框架分成三部分：
一、wifi初始化过程
这个过程中主要做的事情是加载wifi驱动，读数据库，初始化wlan各项参
数，启动wifi。
二、为上层应用提供控制接口，供上层应用设置wifi各项功能。
这部分主要是为上层应用程序提供设置接口，上层其他应用程序将wlan各
项写入数据库中，然后重启wlan进程，wlan重启后读数据库重新进行初始化过程使用户的设置生效。
三、去使能wlan设置
用户关机时对wlan进行相应的去初始化操作。
