vmlinux.lds.s文件分析

vmlinux.lds.S是如何组织内核的每个函数存放在内核镜像文件的位置，我们知道你在编译内核生成内核文件的时候，其实这个过程分两步，一个是“编译”，另一个是“链接”的过程，vmlinux.lds.S要做的就是告诉编译器如何链接编译好的各个内核.o文件。

1. 小知识：链接器中的entry 
   
2. 链接器 按以下优先顺序设入口点,找到即停止 
   
3. 1 -e 命令行选项 
   
4. 2 脚本中的entry(symbol)命令 
   
5. 3如定义了start的值,取其值为入口点 
   
6. 4.text的第一个字节的地址 
   
7. 5地址0

复制代码

所以你可以从vmlinux.lds.S下面的代码中看到：

1. OUTPUT_ARCH(arm)
   
2. ENTRY(stext)

复制代码

表明我们指定stext作为， 程序 的入口点。

先看第一个知识点:

（1）. = PAGE_OFFSET + TEXT_OFFSET;

arch/arm/include/asm中的memory.h文件定义了：

1. #define PAGE_OFFSET                UL(CONFIG_PAGE_OFFSET)

复制代码

CONFIG_PAGE_OFFSET是在内核配置里面配置的，比如拿ok6410来说，我的配置：

扫描二维码关注公众号，回复： 2380357 查看本文章

1. #define CONFIG_PAGE_OFFSET 0xC0000000

复制代码

PAGE_OFFSET代表是的内核image的的起始虚拟地址。

在arch/arm/Makefile中有定义：

1. textofs-y        := 0x00008000
   
2. TEXT_OFFSET := $(textofs-y)

复制代码

TEXT_OFFSET代表的是内核的image存放在内存中地址，注意这个地址为相对于内存的起始地址的偏移量，是个相对的偏移量不是实际的存放内存物理地址。而且这个偏移量取得有讲究，必须为：0xXXXX8000，xxx为任意值。

所以：. = PAGE_OFFSET + TEXT_OFFSET就变成为：.=c0008000，这个地址就是内核存放在内存的虚拟的起始地址。从脚本来看，也就是.stext的地址就是：c0008000，那么我们如何验证我们的这个说法呢，你可以打开linux目录下的System.map文件查看：

1. 00000020 A cpu_v6_suspend_size
   
2. c0004000 A swapper_pg_dir
   
3. c0008000 T __init_begin
   
4. c0008000 T _stext  T _sinittext
   
5. c0008000 T _stext
   
6. c0008000 T stext
   
7. c000804c t __create_page_tables
   
8. c0008148 t __enable_mmu_loc
   
9. c0008154 t __enable_mmu
   
10. c0008180 t __turn_mmu_on
    
11. c0008198 t __enable_mmu_end
    
12. c0008198 t __vet_atags
    
13. c00081e0 t __mmap_switched
    
14. c0008228 t __mmap_switched_data
    
15. c000824c T lookup_processor_type
    
16. c0008260 t set_reset_devices
    
17. c0008284 t debug_kernel

复制代码

从map文件可以知道_stext是内核的入口地址，这个地址就是c0008000，这也验证了我们在第一章讲搭建环境的时候，我为什么要用dnw c0008000，就是因为我们已经指定好了，内核的存放地址必须为c0008000，针对ok6410来说。

（二）.init内核的初始化代码和数据段

1.                 _sinittext = .;
   
2.                         HEAD_TEXT
   
3.                         INIT_TEXT
   
4.                         ARM_EXIT_KEEP(EXIT_TEXT)
   
5.                 _einittext = .;

复制代码

从上面的链接脚本可以知道所有：_sinittext开头的，_einittext结尾的HEAD_TEXT， INIT_TEXT，ARM_EXIT_KEEP(EXIT_TEXT)段都是从起始地址c0008000开始存放的。这些宏定义在：include/asm-generic/vmlinux.lds.h中。

1. __arch_info_begin = .;
   
2.                         *(.arch.info.init)
   
3.                 __arch_info_end = .;
   
4.                 __tagtable_begin = .;
   
5.                         *(.taglist.init)
   
6.                 __tagtable_end = .;
   
7. #ifdef CONFIG_SMP_ON_UP
   
8.                 __smpalt_begin = .;
   
9.                         *(.alt.smp.init)
   
10.                 __smpalt_end = .;
    
11. #endif
    
12. 
    
13.                 __pv_table_begin = .;
    
14.                         *(.pv_table)
    
15.                 __pv_table_end = .;

复制代码

紧接着以此存放的是：*(.arch.info.init)， *(.taglist.init)，*(.alt.smp.init)，*(.pv_table)段的代码，其中我们最熟悉的*(.arch.info.init)段的代码就是：

1. #define MACHINE_START(_type,_name)                        \
   
2. static const struct machine_desc __mach_desc_##_type        \
   
3. __used                                                        \
   
4. __attribute__((__section__(".arch.info.init"))) = {        \
   
5.         .nr                = MACH_TYPE_##_type,                \
   
6.         .name                = _name,
   
7. 
   
8. #define MACHINE_END                                \
   
9. };

复制代码

也就是说所有平台的下面这段代码都放到了*(.arch.info.init)段中：

1. MACHINE_START(MCUOS6410, "MCUOS6410")
   
2.         /* Maintainer: Ben Dooks <[email protected]> */
   
3.         .boot_params        = S3C64XX_PA_SDRAM + 0x100,
   
4. 
   
5.         .init_irq        = s3c6410_init_irq,
   
6.         .map_io                = mcuos6410_map_io,
   
7.         .init_machine        = mcuos6410_machine_init,
   
8.         .timer                = &s3c24xx_timer,
   
9. MACHINE_END

复制代码

紧接着存放的是初始化数据段：

1. #ifndef CONFIG_XIP_KERNEL
   
2.                 __init_begin = _stext;
   
3.                 INIT_DATA
   
4.                 ARM_EXIT_KEEP(EXIT_DATA)
   
5. #endif
   
6.         }
   
7. 
   
8.         PERCPU_SECTION(32)
   
9. 
   
10. #ifndef CONFIG_XIP_KERNEL
    
11.         . = ALIGN(PAGE_SIZE);
    
12.         __init_end = .;
    
13. #endif

复制代码

这个段存放的是所有*(.init.data)，*(.init.rodata)段中的代码。

.init段中的代码段和数据段，在Linux初始化完成之后，这个段的内存都会被请空，被释放。因为他们只需要在初始化的时候使用一次，没有必要再驻留在内存中，浪费空间。为了验证我们以上的分析，我们可以查看system.map这个文件，下面我们看到的从_sinittext开头的，_einittext结尾的所有函数，都会在初始化完成之后被释放：

（3）真正的驻留在内存中的内核内代码段

从脚本上来看，所有.text开始，.etext结束区间的段都是内核代码段：

1.         .text : {                        /* Real text segment                */
   
2.                 _text = .;                /* Text and read-only data        */
   
3.                         __exception_text_start = .;
   
4.                         *(.exception.text)
   
5.                         __exception_text_end = .;
   
6.                         IRQENTRY_TEXT
   
7.                         TEXT_TEXT
   
8.                         SCHED_TEXT
   
9.                         LOCK_TEXT
   
10.                         KPROBES_TEXT
    
11. #ifdef CONFIG_MMU
    
12.                         *(.fixup)
    
13. #endif
    
14.                         *(.gnu.warning)
    
15.                         *(.rodata)
    
16.                         *(.rodata.*)
    
17.                         *(.glue_7)
    
18.                         *(.glue_7t)
    
19.                 . = ALIGN(4);
    
20.                 *(.got)                        /* Global offset table                */
    
21.                         ARM_CPU_KEEP(PROC_INFO)
    
22.         }
    
23. 
    
24.         RO_DATA(PAGE_SIZE)
    
25. 
    
26. #ifdef CONFIG_ARM_UNWIND
    
27.         /*
    
28.          * Stack unwinding tables
    
29.          */
    
30.         . = ALIGN(8);
    
31.         .ARM.unwind_idx : {
    
32.                 __start_unwind_idx = .;
    
33.                 *(.ARM.exidx*)
    
34.                 __stop_unwind_idx = .;
    
35.         }
    
36.         .ARM.unwind_tab : {
    
37.                 __start_unwind_tab = .;
    
38.                 *(.ARM.extab*)
    
39.                 __stop_unwind_tab = .;
    
40.         }
    
41. #endif
    
42. 
    
43.         _etext = .;                        /* End of text and rodata section */

复制代码

这些段中的代码都是事实在在的内核函数。

（4）已经初始化的data数据段：

1. .data : AT(__data_loc) {
   
2.                 _data = .;                /* address in memory */
   
3.                 _sdata = .;
   
4. 
   
5.                 /*
   
6.                  * first, the init task union, aligned
   
7.                  * to an 8192 byte boundary.
   
8.                  */
   
9.                 INIT_TASK_DATA(THREAD_SIZE)
   
10. 
    
11. #ifdef CONFIG_XIP_KERNEL
    
12.                 . = ALIGN(PAGE_SIZE);
    
13.                 __init_begin = .;
    
14.                 INIT_DATA
    
15.                 ARM_EXIT_KEEP(EXIT_DATA)
    
16.                 . = ALIGN(PAGE_SIZE);
    
17.                 __init_end = .;
    
18. #endif
    
19. 
    
20.                 NOSAVE_DATA
    
21.                 CACHELINE_ALIGNED_DATA(32)
    
22.                 READ_MOSTLY_DATA(32)
    
23. 
    
24.                 /*
    
25.                  * The exception fixup table (might need resorting at runtime)
    
26.                  */
    
27.                 . = ALIGN(32);
    
28.                 __start___ex_table = .;
    
29. #ifdef CONFIG_MMU
    
30.                 *(__ex_table)
    
31. #endif
    
32.                 __stop___ex_table = .;
    
33. 
    
34.                 /*
    
35.                  * and the usual data section
    
36.                  */
    
37.                 DATA_DATA
    
38.                 CONSTRUCTORS
    
39. 
    
40.                 _edata = .;

复制代码

（5）紧接着以初始化的.data段的是.bss，未经初始化的内核数据段。

1.         BSS_SECTION(0, 0, 0)
   
2.         _end = .;

复制代码

最后我给出这些段的大致位置图，请参考我们上面所讲的来看：
