Hello

Is there a kGDB kernel patch available for Kernel level 2.2.14-5.0? If not can the 2.2.12 patch be applied

to the newer kernel? I am porting a network device driver to Red Hat 6.2 and need kernel debug capabilities. Any information you can supply would be extremely appreciated. Thanks!

Remote gdb is really my last hope. I tried getting crash dumps working, and that failed. I tried the kernel debugger and that failed. I'm hoping I can get this up in the air so I can work on some issues this week. :-) I've got the patch for RH 6.2 kernel and it applied clean. No problems there. Built the kernel and selected the CONFIG_GDB option. make dep, make bzImage, make modules, blah blah. All worked fine. I put an entry in my lilo.conf file that reads: boot=/dev/sda map=/boot/map install=/boot/boot.b prompt timeout=50 default=linux-gdb image=/boot/vmlinuz-2.2.14-gdb append="gdb gdbttyS=0 gdbbaud=9600" label=linux-gdb initrd=/boot/initrd-2.2.14-5.0smp.img read-only root=/dev/sda1 I then reran lilo (with no complaints) and rebooted my machine. On my (dare I say it) NT box. I'm running CRT with a serial cable hooked from com2 on my NT box to com1 on my linux box. The settings for my term are: port: com2 baud: 9600 data: 8 part: none stop: 1 no flow control. When I reboot the linux-gdb kernel it never stops. It just happily boots up and never asks for input from the serial port. I've tried removing the append string and specifying it on the command line with no luck. Any Ideas what I'm doing wrong? I've signed up for the list, but haven't had a response back, so if you reply please copy me. Thanks. -bmb- Brian M. Boerner System Software Developer Adaptec, Inc.

There was a bug in that the patch was using strcmp instead of strncmp to check for the parameters. Does the patch you use use strncmp in main.c to check for the gdb parameters?

I've spent the better part of my career working on the sparc architecture. My problem is getting the symbol table to show up remotely. I've built the kernel and the modules on the target system. After installing the modules and the kernel, I made a tar file of the source tree and objects and ftped it over to the remote system. I've now got duplicate source trees. I run gdb remotely in the /usr/src/linux-2.2.14-gdb directory. After conenction is established, I load the vmlinux file (gdb) load vmlinux Loading section .text, size 0xb2997 lma 0x80100000 Loading section .text.lock, size 0x2e01 lma 0x801b2998 Loading section .rodata, size 0x22c80 lma 0x801b57a0 Loading section .kstrtab, size 0x2525 lma 0x801d8420 Loading section __ex_table, size 0xcb8 lma 0x801da950 Loading section __ksymtab, size 0x1440 lma 0x801db608 Loading section .data, size 0x29334 lma 0x801dca60 Loading section .data.init_task, size 0x2000 lma 0x80206000 Ignoring packet error, continuing... Loading section .text.init, size 0xac82 lma 0x80208000 Then the system target reboots itself. I'm guessing it takes so long for vmlinux to load, that it times out and reboots.

Where can I get some detailed information on kgdb/gdb setup ? I compiled kernel 2.2.14 with kgdb-patch. It is possible to debug by pressing break now. Then I configured an append "gdb gdbttyS=1 gdbbaud=9600" to do remote debugging. The serial connection via null-cable was tested with minicom and seems ok. How do I have to start gdb on the remote machine now ? How can I stop the "to-debug" machine then ? Thanks for some help ! Ralf Kneemeyer
