Am relatively new to the linux kernel. I have a problem patching the
linux kernel with the kdb kernel debugger.... Here are the steps i
followed. Am not sure if i have missed anything... Kindly help me
out...
1) Untarred the linux-2.6.9 to my home directory
[srikanth@zeus linux]$ pwd
/home/srikanth/work/src/linux
2) Copied kdb-v4.4-2.6.9-i386-1 to /home/srikanth/work/src/linux
3) [srikanth@zeus linux]$ patch -p1 < kdb-v4.4-2.6.9-i386-1
patching file arch/i386/Kconfig.debug
patching file arch/i386/Makefile
patching file arch/i386/kdb/ChangeLog
patching file arch/i386/kdb/Makefile
patching file arch/i386/kdb/i386-dis.c
patching file arch/i386/kdb/kdb_cmds
patching file arch/i386/kdb/kdba_bp.c
patching file arch/i386/kdb/kdba_bt.c
patching file arch/i386/kdb/kdba_id.c
patching file arch/i386/kdb/kdba_io.c
patching file arch/i386/kdb/kdbasupport.c
patching file arch/i386/kdb/pc_keyb.h
patching file arch/i386/kernel/entry.S
patching file arch/i386/kernel/i8259.c
patching file arch/i386/kernel/io_apic.c
patching file arch/i386/kernel/reboot.c
patching file arch/i386/kernel/smp.c
patching file arch/i386/kernel/smpboot.c
patching file arch/i386/kernel/traps.c
patching file arch/i386/kernel/vmlinux.lds.S
patching file include/asm-i386/ansidecl.h
patching file include/asm-i386/bfd.h
patching file include/asm-i386/kdb.h
patching file include/asm-i386/kdbprivate.h
patching file include/asm-i386/kmap_types.h
patching file include/asm-i386/mach-default/irq_vectors.h
patching file include/asm-i386/ptrace.h
patching file kdb/modules/kdbm_x86.c
4) Ran menuconfig and chose Built-in Kernel Debugger support from
Kernel hacking.
I alos chose KDB modules to be built.in
5) Then when i ran make bzImage i got the error as linux/kdb.h not found
[srikanth@zeus linux]$ make bzImage

You did not read the README file in ftp://oss.sgi.com/projects/kdb/download/v4.4,
so you forgot to apply the common kdb patch as well. The KDB README says -
Starting with kdb v2.0 there is a common patch against each kernel which
contains all the architecture independent code plus separate architecture
dependent patches. Apply the common patch for your kernel plus at least
one architecture dependent patch, the architecture patches activate kdb.
The naming convention for kdb patches is :-
vx.y The version of kdb. x.y is updated as new features are added to kdb.
-v.p.s The kernel version that the patch applies to. 's' may include -pre,
-rc or whatever numbering system the kernel keepers have thought up this
week.
-common The common kdb code. Everybody needs this.
-i386 Architecture dependent code for i386.
-ia64 Architecture dependent code for ia64, etc.
-n If there are multiple kdb patches against the same kernel version then
the last number is incremented.
To build kdb for your kernel, apply the common kdb patch which is less
than or equal to the kernel v.p.s, taking the highest value of '-n'
if there is more than one. Apply the relevant arch dependent patch
with the same value of 'vx.y-v.p.s-', taking the highest value of '-n'
if there is more than one.
For example, to use kdb for i386 on kernel 2.6.6, apply
kdb-v4.4-2.6.6-common-<n> (use highest value of <n>)
kdb-v4.4-2.6.6-i386-<n> (use highest value of <n>)
in that order. To use kdb for ia64 with patch 040521 on kernel 2.6.6, apply
kdb-v4.4-2.6.6-common-<n> (use highest value of <n>)
kdb-v4.4-2.6.6-ia64-040521-<n> (use highest value of <n>)
in that order.
Use patch -p1 for all patches.

Might also be worth mentioning that 2.6.9 is a bit dated, if one is
just starting out with the kernel one might as well start with a
recent version.
