# 编译ko模块

Android跟Linux系统通讯依赖于binder和ashmem两个模块，需要编译安装到新内核。

编译和安装ko模块需要用到两个patch文件，均存放在“patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder”路径下，具体编译过程请参考下面的步骤。

1. 创建文件夹，存放ashmem源码。

```
# cd
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/
# mkdir -p ashmem
# mkdir -p ashmem/uapi
# chmod -R 700 ashmem
```


2. 将内核源码目录中“/usr/src/kernels/kernel-5.10.0-60.18.0/drivers/staging/android”文件夹下的指定文件复制到1中创建的“ashmem”文件夹下。

```
# cd
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/ashmem
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/staging/android/ashmem.c ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/staging/android/ashmem.h ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/staging/android/Makefile ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/staging/android/uapi/ashmem.h ./uapi/
```


3. 创建文件夹，存放binder源码。

```
# cd
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/
# mkdir -p binder
# mkdir -p binder/uapi
# chmod -R 700 binder
```


4. 将内核源码目录中“/usr/src/kernels/kernel-5.10.0-60.18.0/drivers/android/”文件夹下的指定文件复制到3中建立的“binder”文件夹下。

```
# cd
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/binder
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/android/binder_alloc.c ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/android/binder_alloc.h ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/android/binder.c ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/android/binder_internal.h ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/android/binder_trace.h ./
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/drivers/android/Makefile ./
```


5. 将内核源码目录中“/usr/src/kernels/kernel-5.10.0-60.18.0/include/uapi/linux/android/”文件夹下的指定文件复制到3中建立的“binder/uapi”文件夹下。

```
# cd
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/binder/uapi
# cp /usr/src/kernels/kernel-5.10.0-60.18.0/include/uapi/linux/android/binder.h ./
```


6. 合入ashmem.patch、binder.patch。

```
# cd
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/
# patch -p1 < ashmem.patch
# patch -p1 < binder.patch
```


7. 编译ashmem。

```
# cd
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/ashmem/
# make KERNEL_SRC=/usr/src/kernels/kernel-5.10.0-60.18.0 V=0 M=
~
/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/ashmem/
# cp ashmem_linux.ko /lib/modules/5.10.0/kernel/lib/
```


8. 编译binder。
  1 2 3 # cd ~/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/binder/ # make KERNEL_SRC=/usr/src/kernels/kernel-5.10.0-60.18.0 V=0 M=~/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/ashmem_binder/binder/ # cp aosp_binder_linux.ko /lib/modules/5.10.0/kernel/lib/
