Hi everyone: Recently I was using kgdb and VMware workstation to debug linux kernel 2.6.26.
I compiled and install kgdb according to the following webpage： http://jaredrobinson.com/blog/using-the-2626-linux-kernel-debugger-kgdb-with-vmware/ But I still have some problems： When I start gdb like：gdb ./vmliunx, it shows： [r...@localhost linux-2.6.26]# gdb ./vmlinux GNU gdb Red Hat Linux (6.6-35.fc8rh) Copyright (C) 2006 Free Software Foundation, Inc.

(gdb) set remotebaud 115200 (gdb) target remote /dev/ttyS0 Remote debugging using /dev/ttyS0 warning: shared library handler failed to enable breakpoint* *0xc045516d in ?? ()** Then I type “n”, it shows： (gdb) n Cannot find bounds of current function I simply realize the output “0xc045516d in ?? ()” is different from common output “breakpoint () at kernel/kgdb.c:1212 1212:atomic_set(&kgdb_setting_breakpoint, 0);” which I found on some webpages The real problem is that when I set breakpoints at like “sys_open”, “sys_getdents64”, the kernel execution didn’t stop at that point. But if I “echo g > /proc/sysrq-trigger ” in target machine, it can stop running. In the development machine, I still only can send “continue” command to make the target run again, if I send “next” command, it shows just like above. Does anybody confront this kind of problems, please give me some suggestions, I really appreciate that! -- Min Li School of Computer Science and Technology Cluster and Grid Computing Lab Services Computing Technology and System Lab Huazhong University of Science and Technology Wuhan, 430074, China Tel: +86-139-8625-1431 Email: [email protected] ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
