请教：声卡驱动移植 [复制链接]

硬件芯片相同，内核都是2。6（一个为2。6。8，一个为2。6。14），2。6。8移植到2。6。14上，
   请教：该怎么作，需要修改那些东西，请指教。
   多谢！

直接copy驱动，然后加入内核模块：修改Kconfig和Makefile，
1。Kconfig
menu "ALSA ARM devices"
        depends on SND!=n && ARM
config SND_S3C24xx_AC97
        tristate "AC 97 driver for the cirrus S3C24xx chip"
        depends on ARCH_S3C2410&&SND
        select SND_S3C24xx_PCM
        select SND_AC97_CODEC
        help
         Say Y or M if you want to support any AC97 codec attached to the S3C24x         x  Ac97 interface
config SND_S3C24xx_PCM
        tristate
        select SND_PCM
"Kconfig" 25L, 639C                                           14,2-9        Top
2。Makefile：中加入代码
obj-$(CONFIG_SND_S3C24xx_PCM)+=s3c24xx-alsa-pcm.o
obj-$(CONFIG_SND_S2C24xx_AC97)+=s3c24xx-alsa-ac97.o

3。在make    menuconfig中选择：
AC 97 driver for the cirrus S3C24xx chip

4编译：make

030303054

5。出现如下错误：
  CHK     include/linux/version.h
make[1]: `include/asm-arm/mach-types.h' is up to date.
  CHK     include/linux/compile.h
  CHK     usr/initramfs_list
  CC      sound/arm/s3c24xx-alsa-pcm.o
