linux下的asm目录，asm代表什么意思

[zifehng]

很多代码这样包含头文件：
#include <asm/irq.h>

但为什么在include目录下没有asm文件夹

[小笨和漂向北方]

it's a kernel header file, usually, it's under /usr/src/kernels/$(uname -r)/arch/x86/include/asm/ cpp looks for header file following a path list and this location or its parent folder could be either under the path or defined in the makefile

[zhxianbin]

不一定在include目录

I don't know, but I found this on TLDP include The include subdirectory contains most of the include files needed to build the kernel code. It too has further subdirectories including one for every architecture supported. The include/asm subdirectory is a soft link to the real include directory needed for this architecture, for example include/asm-i386. To change architectures you need to edit the kernel makefile and rerun the Linux kernel configuration program.

可以在内核中都asm，有这样的文件夹

include下没有asm，只有inlucde/asm-genric

asm表示汇编。

[eziowayne]

C语言无法完成的一些关于寄存器之类的操作全部交给汇编语言。所以kernel有一部分就是汇编写的。你的一些系统调用也许就要用到它们！

[图灵转世]

表示汇编。x86汇编。
