gdb drivers: load address for kernel mode components

[q4a]

I'm trying to use GDB as kernel-mode debugger. http://www.reactos.org/wiki/GDB is outdated, but anyway.
I stopped at section "Making GDB useful". I want to add fastfat.sys to debug:

Code: Select all

(dbg)add-symbol-file E:/ros/trunk/reactos/output-i386/drivers/filesystems/fastfat/fastfat.nostrip.sys
The address where E:/ros/trunk/reactos/output-i386/drivers/filesystems/fastfat/fastfat.nostrip.sys has been loaded is missing

^ That's ok. I need to add 2nd parameter - load address, but how can i set or get it?

1. ntoskrnl/ldr/loader.c was removed from trunk in r25886
"Remove /ldr ntoskrnl directory, since this module is finally gone."
2. http://www.reactos.org/wiki/Rossym.gdb doesn't help:

Code: Select all

(dbg)source E:/ros/trunk/reactos/lib/rossym/rossym.gdb
(dbg)load-all-modules
No symbol "KDB_MODULE_INFO" in current context.

PS my previous steps:
1.Remove obj-i386, output-i386, makefile-i386.auto.
2.Copy config.template.rbuild to config.rbuild and set:
<property name="GDB" value="1" />
3.make ROS_BUILDNOSTRIP=yes bootcd
4.Start qemu with command line option "-gdb tcp::5022":
qemu -L bios -m 1024 -cdrom ..\trunk\reactos\ReactOS.iso -boot d -hda ..\hdd\rgdb-5g.vmdk -serial file:log\rgdb-5g.txt -gdb tcp::5022
5.Install ros.
6.Add /DEBUGPORT=GDB to [ReactOS_Debug] options in freeldr.ini.
7.Reboot and choose "ReactOS (Debug)". Now i see "Waiting for GDB to attach"
8.Start gdb without parameters.

Hi

1. Source-level debugging with GDB sucks. Better to debug on a machine code level. Load addresses get from here.
2. With QEMU, you don't need to compile ReactOS with <property name="GDB" value="1" /> and pass /DEBUGPORT=GDB to the kernel. Attach GDB to QEMU, as explained in the QEMU docs. It works much better.

[ThePhysicist]

Source level debugging with GDB isn't that bad, only the support for Windows sucks a bit.
You can use eclipse as gui then it works quite well.
Also to get symbols, you will currently need to disable rsym to generate stabs in the executables instead of the reactos own format. (just put a return 0; in tools/rsym/rsym.c main())

Thx.

I run qemu with "-s -S" options instead of "-gdb tcp::5022", but it doesn't work for me:
cat E:/ros/gdb/g.gdb:

And it doesn't break in KdpSerialInit(ntoskrnl\kd\kdio.c:272), but i'm sure that it goes there, because i got:

1. Run QEMU with -s option (and -S, if necessary, but I usually don't use it). -s is not strictly needed, either (you can enter gdbserver in QEMU console).
2. Run GDB, attach it to QEMU with target remote :1234. set remotebaud 115200 is not needed. QEMU will stop (with -S it stops immediately after start).
3. To resume QEMU, enter c (or cont) in GDB or in QEMU console. To stop it, press Ctrl-C in GDB or enter stop in QEMU console.

And it will not break in KdpSerialInit(); you should insert breakpoint(s) yourself wherever you want.

Thx again. It seems, that i have problems with breaking NTAPI functions(in says "Function "KdpSerialInit" not defined."), but with other functions like KdbpTryGetCharKeyboard(ntoskrnl/kdbg/kdb_keyboard.c:107) it works fine.
Anyway i can use "break ntoskrnl\kd\kdio.c:272" instead of "break KdpSerialInit" and it works for me =)

And by the way Ctrl-C abort all gdb session in MinGW Shell, but in Windows's cmd it works fine. If somebody interested - my gdb-log:

ADD: hto, don't you know how to call kdbg in 1st stage of installing ros? I tried to use TAB-K and i see "kdb:>" in output file, but i can't execute any command. It seems freeze.
But when i using TAB-K on installed ros - it works great and i can use "bt" and other kdb's commands.

Sorry, I misread your 2nd post.

These problems look like bugs in GDB (can't break in NTAPI functions) and in ReactOS (KDB in the 1st stage). Maybe you will want to debug them.
