在Linux中找不到syscall_table_32.S文件 [英] Unable to find syscall_table_32.S file in linux

问题描述

我在虚拟机上使用linux-headers-2.6.32-21软件包.我要编写一个新的系统调用.我找到了其他文件来写系统调用的首字母，但在arch/x86/kernel/目录中找不到此syscall_table_32.S.请帮助我如何以及在哪里可以找到此文件.我怀疑它可能由于权限问题或其他原因而被隐藏.

I am using the linux-headers-2.6.32-21 package on Virtual Machine. I am going to write a new system call. I have found the other files to write initials of system calls but I am unable to find this syscall_table_32.S in arch/x86/kernel/ directory. Please help me how and where I can find this file. I am doubted that it might be hidden due to permission issues or others.

    x86: Generate system call tables and unistd_*.h from tables

    Generate system call tables and unistd_*.h automatically from the
    tables in arch/x86/syscalls.  All other information, like NR_syscalls,
    is auto-generated, some of which is in asm-offsets_*.c.

    This allows us to keep all the system call information in one place,
    and allows for kernel space and user space to see different
    information; this is currently used for the ia32 system call numbers
    when building the 64-bit kernel, but will be used by the x32 ABI in
    the near future.

    This also removes some gratuitious differences between i386, x86-64
    and ia32; in particular, now all system call tables are generated with
    the same mechanism.

因为现在syscall表是由脚本arch/x86/syscalls/syscalltbl.sh基于arch/x86/syscalls/syscall_ {32,64} .tbl生成的.

because now syscall table is generated by the script arch/x86/syscalls/syscalltbl.sh, based on arch/x86/syscalls/syscall_{32,64}.tbl.
