全志H3移植Linux4.20.17的RTL8189FTV驱动

设备与软件版本

  • OrangePi Lite
  • RTL8189FTV
  • Linux 4.20.17 mainline

1.开启MMC控制器

1.1 开启MMC1

  • 根据原理图RTL8189FTV挂在在MMC1
  • 编辑设备树文件linux-4.20.17/arch/arm/boot/dts/sunxi-h3-h5.dtsi，开启mmc1 
          mmc1: mmc@1c10000 {
          /* compatible and clocks are in per SoC .dtsi file */
          reg = <0x01c10000 0x1000>;
          pinctrl-names = "default";
          pinctrl-0 = <&mmc1_pins>;
          resets = <&ccu RST_BUS_MMC1>;
          reset-names = "ahb";
          interrupts = <GIC_SPI 61 IRQ_TYPE_LEVEL_HIGH>;
          status = "okay";
          #address-cells = <1>;
          #size-cells = <0>;
      };

    1.2 绑定MMC1与rtl8189ftv

  • 编辑设备树文件linux-4.20.17/arch/arm/boot/dts/sun8i-h3-orangepi-lite.dts 
    &mmc1 {
  vmmc-supply = <&reg_vcc3v3>;
  bus-width = <4>;
  non-removable;
  status = "okay";

  /*
   * Explicitly define the sdio device, so that we can add an ethernet
   * alias for it (which e.g. makes u-boot set a mac-address).
   */
  rtl8189ftv: sdio_wifi@1 {
      reg = <1>;
  };
};

2.移植RTL8189FTV驱动

2.1替换新的设备树文件，启动后查看SDIO_ID确定设备驱动

[root@OrangePi_Lite /]# cat /sys/bus/sdio/devices/mmc1\:0001\:1/uevent                              
DRIVER=rtl8189fs                                                                                    
OF_NAME=sdio_wifi                                                                                   
OF_FULLNAME=/soc/mmc@1c10000/sdio_wifi@1                                                            
OF_COMPATIBLE_N=0                                                                                   
OF_ALIAS_0=ethernet0                                                                                
SDIO_CLASS=07                                                                                       
SDIO_ID=024C:F179                                                                                   
MODALIAS=sdio:c07v024CdF179

2.2下载驱动代码

  • git clone https://github.com/jwrdegoede/rtl8189ES_linux.git
  • cd tl8189ES_linux
  • git checkout -b rtl8189fs origin/rtl8189fs
  • git pull
  • 根据os_dep/linux/sdio_intf.c与SDIO_ID确定匹配设备驱动为CONFIG_RTL8188F

2.3配置驱动代码Makefile

  • CONFIG_RTL8188F = y
  • CONFIG_SDIO_HCI = y
  • CONFIG_PLATFORM_ARM_SUNxI = y 
    ifeq ($(CONFIG_PLATFORM_ARM_SUNxI), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
EXTRA_CFLAGS += -DCONFIG_PLATFORM_ARM_SUNxI
#default setting for Android 4.1, 4.2
EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
EXTRA_CFLAGS += -DCONFIG_IOCTL_CFG80211 -DRTW_USE_CFG80211_STA_EVENT
EXTRA_CFLAGS += -DCONFIG_PLATFORM_OPS
ifeq ($(CONFIG_USB_HCI), y)
EXTRA_CFLAGS += -DCONFIG_USE_USB_BUFFER_ALLOC_TX
_PLATFORM_FILES += platform/platform_ARM_SUNxI_usb.o
endif
ifeq ($(CONFIG_SDIO_HCI), y)
#default setting for A10-EVB mmc0
#EXTRA_CFLAGS += -DCONFIG_WITS_EVB_V13
_PLATFORM_FILES += platform/platform_ARM_SUNxI_sdio.o
endif
ARCH := arm
#CROSS_COMPILE := arm-none-linux-gnueabi-
#CROSS_COMPILE=/home/android_sdk/Allwinner/a10/android-jb42/lichee-jb42/buildroot/output/external-toolchain/bin/arm-none-linux-gnueabi-
#KVER  := 3.0.8
#KSRC:= ../lichee/linux-3.0/
#KSRC=/home/android_sdk/Allwinner/a10/android-jb42/lichee-jb42/linux-3.0
KVER := 4.20.17
CROSS_COMPILE := /opt/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
KSRC=/home/jin/linux-4.20.17
endif

2.4针对Linux4.20.17作出修改

  • LINUX_VERSION_CODE似乎并没有起作用，强制修改os_dep/linux/os_intfs.c 
    static u16 rtw_select_queue(struct net_device *dev, struct sk_buff *skb
              , struct net_device *sb_dev
              , select_queue_fallback_t fallback
)
{
  _adapter	*padapter = rtw_netdev_priv(dev);
  struct mlme_priv *pmlmepriv = &padapter->mlmepriv;

  skb->priority = rtw_classify8021d(skb);

  if(pmlmepriv->acm_mask != 0)
  {
      skb->priority = qos_acm(pmlmepriv->acm_mask, skb->priority);
  }

  return rtw_1d_to_queue[skb->priority];
}

2.5编译驱动

  • 编译得到8189fs.ko
  • 复制到目标系统的文件

3.配置内核cfg80211
