Creating a .config File

The first step to compile the kernel is to create a .config file in which the functions and features that need to be enabled are declared.

1. Copy the config file to the source code directory and rename it .config.

   # cp ~/dependency/patchForKernel/openEuler_22.03/kernel_5.10.0/kernel/config-5.10.0-60.18.0.50.oe2203.aarch64 /usr/src/kernels/kernel-5.10.0-60.18.0
   # cd /usr/src/kernels/kernel-5.10.0-60.18.0
   # mv config-5.10.0-60.18.0.50.oe2203.aarch64 .config

2. Generate a .config file.

   # cd /usr/src/kernels/kernel-5.10.0-60.18.0
