在Linux内核中，是asm还是asm-generic? [英] in linux kernel, asm or asm-generic?

问题描述

在mm/memory.c中，它包含一个文件:

in mm/memory.c, it includes one file:

#include <asm/tlb.h>

tlb.h 是 include/asm-generic/tlb.h 或 arch/arm/include/asm/tlb.h ?

推荐答案

如有必要， arch/arm/include/asm 中的头文件将在 include/中包含相应的头文件.通用asm .

If necessary, header files in arch/arm/include/asm, will include the corresponding header file in include/asm-generic.

因此，在这种情况下， tlb.h 是 arch/arm/include/asm/tlb.h .并在必要时包含 include/asm-generic/tlb.h .

So in this instance, tlb.h is arch/arm/include/asm/tlb.h. And if necessary, it will include include/asm-generic/tlb.h.

您可以通过运行以下命令来验证这一点:

You can verify this by running the following command:

# The memory.s target creates the assembly file for memory.c
make mm/memory.s

由此，您可以确定正在使用哪个头文件.

From that, you can identify which header file is being used.
