In ddd (display debugger), the source windows doesn't show the original assembly source code for linux debug

Question

I was debugging a linux assembly code but in the assembly source code window, the current line is at the top of the window and all the future lines are display below. I want to see some lines that I have already passed. How can I do that? Please see the photo below.

Answer 1

I have done this before but I had forgotten how to do it this time.
I figured out, the correct method is, when readelf -S vmlinux shows this,

Section Headers:
  [Nr] Name              Type             Address           Offset
       Size              EntSize          Flags  Link  Info  Align
  [ 0]                   NULL             0000000000000000  00000000
       0000000000000000  0000000000000000           0     0     0
  [ 1] .head.text        PROGBITS         ffffffc008000000  00010000
       0000000000000040  0000000000000000  AX       0     0     4
  [ 2] .text             PROGBITS         ffffffc008010000  00020000
       0000000000389c18  0000000000000008  AX       0     0     65536
  [ 3] .got.plt          PROGBITS         ffffffc008399c18  003a9c18
       0000000000000018  0000000000000008  WA       0     0     8
  [ 4] .rodata           PROGBITS         ffffffc0083a0000  003b0000
       00000000000cc852  0000000000000000  WA       0     0     4096
   .... 

in the debugger command window,

add-symbol-file ../../LinuxDevDrv/linux-5.15.68/vmlinux -s .text 0x80210000

In my case, the physical load address of linux 'Image' was 0x80200000. Since the address of .text is 0x10000 from the start of .head.txt(comparing the virtual addresses), I gave 0x80210000 as the physical address of section .text.
When you do this, the original assembly code appears on the source code window.
