mips平台下firmware内核以及Linux 标准内核编译手册

编译目标

  • 源码生成二进制文件

  • 源码生成llvm IR文件

  • 编译源码

Lable "Y" 代表已经编译完成的版本，可以使用软链接方式链接到srcs目录下进行编译。

GCC交叉编译工具链位置

/opt/brcm

将交叉编译工具链导入到PATH:

export PATH=$PATH:/opt/brcm/hndtools-mipsel-linux/bin:/opt/brcm/hndtools-mipsel-uclibc/bin:/opt/brcm-arm/bin

export LD_LIBRARY_PATH=/opt/brcm/hnel-linux/lib:$LD_LIBRARY_PATH

clang交叉编译工具链位置

/home/yjq/Fulirong/Tools/cheq/llvm/llvm-project/prefixMips/bin/clang

使用的clang（编译平台需要指明为mips，需要打补丁，禁止函数内联）

源代码位置：

/home/yjq/Fulirong/Tools/cheq/deadline-arm/code/srcs

IR位置：

/home/yjq/Fulirong/Tools/cheq/deadline-arm/code/bcfs

编译命令

使用deadline工具 (Refer to https://github.com/sslab-gatech/deadline)进行编译

Config : ./main.py config
Build w/gcc (3 hours) : ./main.py build
Parse build procedure : ./main.py parse
Build w/llvm : ./main.py irgen

编译文件修改

修改源文件Makefile

​ vi src/linux_stable-eddition/Makefile

Set ARCH ARCH=mips

Set CROSS_COMPILE CROSS_COMPILE=mipsel-linux-

保证firmware Makefile 文件和kernel Makefile 文件相同，若不同，取firmware Makefile
当生成parse.log后，将log文件中的优化级别（-Os）修改为 -O0后再生成中间文件

编译错误总结

Eddition 2.6.36.4
(1) silentold config error

修改obj/linux_stable-2.6.36/.config 60行，设置 CONFIG_RAM_SIZE =1024 

修改 obj/linux_stable-2.6.36/.config 设置  **CONFIG_DYNAMIC_DEBUG** is no set

(2) /mips/include/asm/checksum.h:285:27: error: unsupported inline asm: input with type '__be32' (aka 'unsigned int') matching output with type 'unsigned  short'

(3) error: "MIPS, but neither __MIPSEB__, nor __MIPSEL__???"

出现这个问题的根本原因在于，clang编译时没有识别到编译大端还是小端的文件，因此导致变量没有定义。目前的做法是，把le.h和byteorder.h报错的那句删除，然后在le.h 中强行定义为大端，需要修改以下几个文件。

arch/mips/include/asm/byteorder.h 

include/asm-generic/bitops/le.h

arch/mips/include/uapi/asm/bitfield.h

arch/mips/include/uapi/asm/byteorder.h 

arch/mips/include/asm/unaligned.h

(4) unsupported inline asm input with type '__be32'

replacing  `d_alias` member to `d_u.d_alias` should help with that compatibility problem.
