Hi,
I am using gdb to debug a kernel loadable module. My kernel version is
2.6.27-8 and the gdb version is 6.8-29.fc10. I compiled the kernel with KGDB
on and boot the kernel with kgdboc. I can attach the running kernel remotely
to the gdb during boot and so on. After the system boot up, I can get the
module's text address from /proc/modules and load it to the gdb with
"add-symbols-file e1000.ko 0xff..." (using e1000 driver as an example and I am
on x86_64 box). I can set a breakpoint such as e1000_reset, but there is not
source line shown under the info command:
(kgdb) add-symbol-file drivers/net/e1000/e1000.ko 0xffffffffa00b0000
add symbol table from file "drivers/net/e1000/e1000.ko" at
.text_addr = 0xffffffffa00b0000
(y or n) y
Reading symbols from
/home/sxu/src/trunk_0414/kernel/vanilla/drivers/net/e1000/e1000.ko...done.
(kgdb) info b
Num Type Disp Enb Address What
1 breakpoint keep y 0xffffffff8023e833 in sys_kill
at kernel/signal.c:2206
breakpoint already hit 5 times
2 breakpoint keep y 0xffffffffa00b2162 <e1000_reset>
<=== No source file and line number here
The e1000_reset break can be triggered but I can not see the source code. I
tried the "dir" gdb command, but had no luck.
Anyone can advise me to solve this problem?
Thanks in advance.
Stuart
