浅析如何添加自己的ko到make menuconfig中

浅析如何添加自己的ko到make menuconfig中

其实向make menuconfig添加自己的选项,仅仅是为了向driver传递由用户自己决定的几个不同的宏值.

1.
luther@gliethttp:/vobs/works/lnx2625pxa/drivers/net/wireless$ mkdir bcmxxx
2.
luther@gliethttp:/vobs/works/lnx2625pxa/drivers/net/wireless$ vim Kconfig
追加如下内容：
config BCMXXX
    tristate "BCMXXX WLAN driver support"
    depends on WLAN_80211
    select WIRELESS_EXT
    select FW_LOADER
    ---help---
      A driver for Broadcom xxx devices.
source "drivers/net/wireless/bcmxxx/Kconfig" //如果加入的bcmxxx模块有很多宏需要控制,那么加入该选项,进行进一步细致 控制,否则可以去掉
3.向/vobs/works/lnx2625pxa/.config添加,我们的BCMXXX编译时的缺省值.
因为我们的.config是由/vobs/works/lnx2625pxa/setup.sh PRODUCT=xxx产品名称 root=ramdisk来自动生成的,所以应该修改
/vobs/works/lnx2625pxa/arch/arm/configs/xxx产品名称_defconfig中的数值才行.
CONFIG_MRVL8688=m //默认为module
CONFIG_BCMXXX=m //默认为module
4.
luther@gliethttp:/vobs/works/lnx2625pxa$ make menuconfig
这样在
Device Drivers==>Network device support==>Wireless LAN==>就会有加入的
BCMXXX WLAN driver support //这个选项了
对它的修改将直接影响到CONFIG_MRVL8688变量.
5.让他能够被make到
向上级可执行目录追加编译选项
drivers/net/wireless/Makefile|51| obj-$(CONFIG_MRVL8688)        += mrvl8688/
luther@gliethttp:/vobs/works/lnx2625pxa/drivers/net/wireless$ vim Makefile
obj-$(CONFIG_BCMXXX)        += bcmxxx/ //表示当执行make zImage或者make时,需要执行bcmxxx目录下的Makefile文件
但是因为bcmxxx在pc上的编译比较特殊,需要到bcmsdio/linux目录下执行,
luther@gliethttp:/vobs/works/broadcom/src/bcmsdio/linux$ make -j4
所以上面的地址也应该改为
obj-$(CONFIG_BCMXXX)        += bcmxxx/bcmsdio/linux
luther@gliethttp:/vobs/works/broadcom/src/bcmsdio/linux$ vim Makefile
加入如下行
LINUXDIR := $(KBUILD_SRC) //内核/vobs/works/lnx2625pxa/Makefile导出export变量

obj-$(CONFIG_) += sd8688.o


6.将需要加入的bcmxxx驱动放到/vobs/works/lnx2625pxa/drivers/net/wireless/bcmxxx/目录下
然后编写Makefile,好了工作完成了
7.编译了
luther@gliethttp:/vobs/works/lnx2625pxa$ make -j4

在sd8688中作如下修改:

drivers/net/wireless/Makefile|51| obj-$(CONFIG_MRVL8688)        += mrvl8688/

在drivers/net/wireless/Kconfig中
config MRVL8688   //对应CONFIG_MRVL8688变量,可以在.config中定义默认值
    tristate "Marvell 8688 WLAN driver support"
    depends on WLAN_80211

    ---help---
      A driver for Marvell 8688 devices.

source "drivers/net/wireless/mrvl8688/Kconfig" 表示调入相应Kconfig,放到下面

    bool "Marvell 8688 debugging"
    depends on MRVL8688
