我正在使用虚拟机上的linux-headers-2.6.32-21软件包。 我要写一个新的系统调用。 我发现其他文件写入系统调用的首字母，但我无法在arch/x86/kernel/目录中find此syscall_table_32.S 。 请帮助我如何以及在哪里可以find这个文件。 我怀疑它可能因许可问题或其他原因而被隐藏。
以下提交删除它：
commit 303395ac3bf3e2cb488435537d416bc840438fcb Author: H. Peter Anvin <hpa@linux.intel.com> Date: Fri Nov 11 16:07:41 2011 -0800 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arch / x86 / syscalls / syscalltbl.sh脚本根据arch / x86 / syscalls / syscall_ {32,64} .tbl生成的。
/usr/src/kernels/3.3.4-5.fc17.i686.PAE/arch/x86/include/generated/asm
在这里你可以得到syscalls_32.h。
