- | ==== Linux coding style ==== | + | This is the coding style document for [[en/users/Drivers/ath10k|ath10k]], [[en/users/Drivers/ath11k|ath11k]] and [[en/users/Drivers/ath12k|ath12k]] drivers. Read this before writing any code. |
+ | |||
+ | ==== Tools ===== | ||
+ | |||
+ | Use latest GCC which you can download from [[https://mirrors.edge.kernel.org/pub/tools/crosstool/|crosstool]]. Setting it up is easy, unpack it to a directory and create a GNUmakefile: | ||
+ | |||
+ | <code> | ||
+ | ARCH=x86 | ||
+ | CROSS_COMPILE=/opt/cross/gcc-13.2.0-nolibc/x86_64-linux/bin/x86_64-linux- | ||
+ | |||
+ | export ARCH | ||
+ | export CROSS_COMPILE | ||
+ | </code> | ||
- | ath10k mostly follows [[https://www.kernel.org/doc/html/latest/process/coding-style.html|Linux Coding Style]], so read that first. | + | You will need [[https://docs.kernel.org/dev-tools/sparse.html#getting-sparse|the latest sparse from git]]. Linux distros usually have too old sparse and you will see wrong errors! |
