RH apply a lot of patches which conflict with kdb, you have to ask RH for a working version of kdb against their kernels.

The latest kdb patches for IA64 are the best starting point, the ix86 patch is more intrusive. ftp://oss.sgi.com/projects/kdb/download/v2.5/ kdb-v2.5-2.4.19-common-1 and kdb-v2.5-2.4.19-ia64-020821-1. You will need a kdb-v2.5-2.4.19-arm-1 patch containing patches against these areas. include/asm-$(ARCH): kdb.h Define KDB_ENTER() and various _fmt strings. kdbprivate.h Replace everything. Long jump support is the hardest, you can start with #undef KDB_HAVE_LONGJMP and add long jump later. It is used for breaking out of long output and recovery from kdb internal errors, such as accessing invalid addresses. arch/$(ARCH): kernel/traps.c Hook into die_if_kernel(), debug handlers etc. Also NMI if supported. kernel/smp.c KDB uses IPI or the equivalent to interrupt other processors. If the IPI can be sent unmaskable, do so. config.in, Makefile Add kdb options. kdb/*.[ch] All the arch dependent code needs to be reworked. Ignore kdba_prologue() for now, IA64 did not fit the prologue framework which is why the code has lots of FIXME comments. kdba_bt decodes the calling sequence. Unwinding the calling frame is tricky, especially when the kernel uses out of line sections for locks. IA64 uses unwind data, ix86 has heuristics based on the way that gcc generates code. kdba_bp implements hardware and software breakpoints. kdba_io has to do IO without using interrupts, kdb disables all interrupts on all cpus. kdba_id handles the high level disassembler work. Most of the work is done by the code extracted from gdb. A large chunk of arch/$(ARCH)/kdb is the dissassembler code lifted from gdb and modified as little as possible to fit the kernel.

And I have used KDB for some days before I come here. I found KDB is really a wonderful tool for Linux kernel developer. It helps me much in my developing work of kernel modules. But, I think the KDB command line is not very friendly. If I make a mistake in the middle of my long command string, I have to input the whole line again. So I wonder if there is any plan to improve the edit ability of the command line. Such as "move left", "move right", "insert char", "delete char", "go to the head", "go to the end" and "move in the history commands", etc. I fail to find these features in the latest patch "kdb-v2.5-2.4.19-common-1" and "kdb-v2.5-2.4.19-i386-1". Do you think this requirement is reasonable for KDB? In order to ease my fingers, I'd like to add these features to the KDB patch. So I tried to add some codes to the KDB. The following 2 patches are for kdb-v2.4-2.4.19. Could you have a try and give me some feedbacks? Only i386 architecture is supported by now. Thank you very much. ^-^ Sonic Zhang 12/4/2002 ---------------------------------------------------------------------------- ---- --- linux-kdb/kdb/kdbmain.c Wed Dec 4 15:53:39 2002 +++ linux-kdb-cmdline/kdb/kdbmain.c Wed Dec 4 10:28:36 2002 @@ -691,7 +691,7 @@ */ #define KDB_CMD_HISTORY_COUNT 32 #define CMD_BUFLEN 200 /* kdb_printf: max printline size == 256 */ -static unsigned int cmd_head, cmd_tail; +static unsigned int cmd_head=0, cmd_tail=0; static unsigned int cmdptr; static char cmd_hist[KDB_CMD_HISTORY_COUNT][CMD_BUFLEN]; @@ -887,22 +887,22 @@ #define CTRL_N 14 /* initial situation */ - if (cmd_head == cmd_tail) return 1; + if (cmd_head == cmd_tail) return 0; switch(*cmd) { - case '\n': case CTRL_P: if (cmdptr != cmd_tail) cmdptr = (cmdptr-1) % KDB_CMD_HISTORY_COUNT; - strcpy(cmd, cmd_hist[cmdptr]); - return 0; + strncpy(cmd_hist[cmd_head], cmd_hist[cmdptr], CMD_BUFLEN); + return 1; case CTRL_N: + if (cmdptr == cmd_head) return 0; if (cmdptr != (cmd_head-1)) cmdptr = (cmdptr+1) % KDB_CMD_HISTORY_COUNT; - strcpy(cmd, cmd_hist[cmdptr]); - return 0; + strncpy(cmd_hist[cmd_head], cmd_hist[cmdptr], CMD_BUFLEN); + return 1; } - return 1; + return 0; } @@ -998,7 +998,7 @@ return KDB_CMD_GO; } break; - case KDB_REASON_CALL: + case KDB_REASON_CALL: if (!regs) kdb_printf("kdb() called with no registers, restricted function\n"); break; @@ -1059,6 +1059,10 @@ KDB_STATE_SET(LONGJMP); #endif /* KDB_HAVE_LONGJMP */ + + cmdbuf = cmd_hist[cmd_head]; + *cmdbuf = '\0'; + do_full_getstr: #if defined(CONFIG_SMP) kdb_printf(kdbgetenv("PROMPT"), smp_processor_id()); @@ -1066,15 +1070,15 @@ kdb_printf(kdbgetenv("PROMPT")); #endif - cmdbuf = cmd_hist[cmd_head]; - *cmdbuf = '\0'; /* * Fetch command from keyboard */ cmdbuf = kdb_getstr(cmdbuf, CMD_BUFLEN, defcmd_in_progress ?

Hello

 

Not sure if anyone has noticed it. Iam seeing the same issues when I use either the kdb or the gdb patches for any kernel 2.4.18 and above.

 

When I set breakpoints, I see it hit once, but never hits the next time. If I delete and set the breakpoint again, it seems to work again. (just one more time)

 

Anyone seen this happen?

 

Thanks

ashokr

Then I do "go" again, on any future printk's I don't see the debugger break into and giving me a kdb prompt. Now I can manually break in using the "break" key, and then delete the breakpoint and set a new one "bp printk" again. Now I see the break happen and kdb prompt appear again.

Hello,

I have downloded the kernel source from kernel.org and applied kdb patch. (version linux-2.4.18.tar.gz, kdb-v2.1-2.4.18-common-1 and kdb-v2.1-2.4.18-i386-1
No problem with that.
I recompiled the kernel after enabling kdb in kernel hacking.
I have installed the newly compiled kernel.

My default run level was 5 (X windows).
I had problem in bringing up X Windows.
I changed the run level to 3.
system cam up well. I could press 'pause' and enter into kdb.
I could execute few commands. But as soon as I try to execute "go" command, system getting hanged. After that nothing works, keyboard getting locked.

Also can we see the C Source in kdb?

Have a nice time.
Arun

People who use serial consoles expect to press the up-arrow key on the
second machine and have it work the same way as up-arrow on a PC
keyboard. The PC keyboard uses scancodes which your patch covered.

The patch version is kdb-2.5-2.4.19 for i386 with pristine kernel 2.4.19. The keyboard cannot work well in KDB. When you press a key, sometimes there is no character echoed on the screen, and sometimes two characters echoed on the screen. It is really annoying because you cannot type continuously. This happens on a server with 2 processors. But I can't reproduce it on my desktop machine. Is it a known bug? Otherwise, sometimes in KDB , only capital letters can be inputted. It may be a little hard to re-produce because when you first enter KDB mode, you may not encounter this situation. After doing some operations in KDB, e.g. set some breakpoint, suddenly I found every letter I input is capital letter and I can not switch to small letter mode. Is this the same problem? Thanks.

The scancode handling is in arch/i386/kdb/kdba_io.c::get_kbd_char(). Some keyboard hardware has problems running in polled mode rather than interrupt driven. The keyboard setup was rewritten in 2.5 kernels and the problems seem to have gone away, my current theory is that these are kernel console problems, not kdb. Unfortunately none of the kdb developers have hardware that shows these problems. Without access to the hardware that is failing, we have to rely on users tracking down the problem.

It is the keyboard switch box, which connects one keyboard with several servers. The switch has problems running in polled mode used by KDB keyboard driver. After I directly connect the keyboard to the server, this bug disappears. Thank you.

The scancode handling is in arch/i386/kdb/kdba_io.c::get_kbd_char(). Some keyboard hardware has problems running in polled mode rather than interrupt driven. The keyboard setup was rewritten in 2.5 kernels and the problems seem to have gone away, my current theory is that these are kernel console problems, not kdb. Unfortunately none of the kdb developers have hardware that shows these problems. Without access to the hardware that is failing, we have to rely on users tracking down the problem. Edit get_kbd_char() to print the current cpu, the scan code being read, the various flags and the final result. Start at the comment 'Fetch the scancode' and work down. Use kdb_printf, not printk and set LINES 10000 first. WOrk out what is going wrong and where.

Can the polling routine for serial console be a culprit here Try attaching the keyboard directly to the machine and not over a KVM. Or try another keyboard. Some keyboards and/or KVMs do not handle polling mode I/O very well. The other possibility is a known race condition in kdb when two cpus hit the same break point at the "same" time. Both cpus try to drive into kdb and they deadlock. I do not have a clean fix for this, except to avoid breakpoints in highly used code.

I am using "kdb-v1.9-2.4.13" on SCO/Caldera OpenLinux 3.1.1 ( with Linux-2.4.13 ). After doing some investigation i could see that KDB is using a polled mechanism to get keyboard input, and in doing so, it is not disabling the signalling of OBF interrupts on the keyboard controller. This leads to spurious keyboard interrupts after exiting from KDB, and also in my case ( with Compaq Deskpro's ) it causes some issues with the keyboard controller's state machine, and keyboard no longer responds. I am including a patch for kdb-v1.9-2.4.13, which disables OBF interrupts on local processor at kdb entry point, and re-enables OBF interrupts at exit point, which seems to solve this keyboard freeze issue. In my opinion this is a generic solution which should work on all keyboard controllers with this kind of behaviour. Issue #2: -------- I have also noticed that using "ssb" command on KDB, causes a complete system freeze. I will be grateful if you can let us know if this is a known issue and if any patch is available for it. Looking fwd. to your early feedback. Thanks & Best Regards, Ashish Kalra.

Thanks, I will port that to the latest version of kdb when I get back from holidays. >I have also noticed that using "ssb" command on KDB, causes a complete system >freeze. I will be grateful if you can let us know if this is a known issue and >if any patch is available for it. Single stepping over instructions that save or restore the flags does not work. This includes pushf, popf, ret, iret, cli, sti. You may be hitting that restriction. More likely you are hitting one of the several single step bugs that have been fixed in the recent versions of kdb, the latest is kdb-v2.5-2.4.20, v1.9-2.4.13 is quite old.

I hope you will enjoy them. One is to automatically complete the kernel symbol name string as long as possible. If a user presses the TAB key after part of the symbol string, the following string shared by all symbols that start with the same prefix is appended. If only one symbol start with the given prefix, this symbol name will be completed. If none prefix is matched, then nothing is added. The other is to list some kernel symbols that start with the given prefix, if a user double presses the TAB key. The symbol count in the list is configured by environment DTABCOUNT. Its default value is 30 and can be configured by the user. If it is set to zero, both of the 2 TAB features are ignored. I don't know whether my new enhancement to the KDB command line is helpful to KDB project. Could you please take a look at my patches and give me some comments. New changes are mainly in file kernel/kallsyms.c and arch/i386/kdba_io.c . The patches should be apply to pristine kernel 2.4.19 with kdb patch v2.5-2.4.19. The patches support PS/2 and USB keyboard, but support to the serial console is not included yet. Thank you very much.

Any version of kdb would be fine. I attempted to patch kdb v2.5 into 2.4.18-14 and after minor changes related to kdb_ps and task_has_cpu, it compiled. But breakpoints don't work and backtrace address appear to be out of sync despite a full mrproper rebuild of the kernel.

This list seems dead, I asked info yesterday about 2.4.20 patch and no one, as of now, has replied. About your problem, you should compile 2.4.19 (or 2.4.20 if the patch is compatible or a new release comes out), as redhat kernels comes customized with a lot of patches and I don't think you'll want to patch the stuff by hand, do you? > Thanks, > Melkor > Cheers, - lr From sonic.zhang@intel.com Sun Dec 22 18:39:18 2002 Received: with ECARTIS (v1.0.0; list kdb); Sun, 22 Dec 2002 18:39:19 -0800 (PST) Received: from hermes.jf.intel.com (fmr05.intel.com [134.134.136.6]) by oss.sgi.com (8.12.5/8.12.5) with SMTP id gBN2dH3v030710 for ; Sun, 22 Dec 2002 18:39:17 -0800 Received: from petasus.jf.intel.com (petasus.jf.intel.com [10.7.209.6]) by hermes.jf.intel.com (8.11.6/8.11.6/d: outer.mc,v 1.51 2002/09/23 20:43:23 dmccart Exp $) with ESMTP id gBN2fmA00531 for ; Mon, 23 Dec 2002 02:41:48 GMT Received: from pdsmsxvs01.pd.intel.com (pdsmsxvs01.pd.intel.com [172.16.12.122]) by petasus.jf.intel.com (8.11.6/8.11.6/d: inner.mc,v 1.27 2002/10/16 23:46:59 dmccart Exp $) with SMTP id gBN2eQk01801 for ; Mon, 23 Dec 2002 02:40:27 GMT Received: from pdsmsx17.pd.intel.com ([172.16.12.121]) by pdsmsxvs01.pd.intel.com (NAVGW 2.5.2.11) with SMTP id M2002122310433629204 ; Mon, 23 Dec 2002 10:43:37 +0800 Received: by pdsmsx17.pd.intel.com with Internet Mail Service (5.5.2653.19) id ; Mon, 23 Dec 2002 10:42:59 +0800 Message-ID: <957BD1C2BF3CD411B6C500A0C944CA2602A196D6@pdsmsx32.pd.intel.com> From: "Zhang, Sonic" To: lucipher , kdb@oss.sgi.com Subject: RE: kdb for 2.4.20 Date: Mon, 23 Dec 2002 10:41:31 +0800 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Content-Type: text/plain; charset="iso-8859-1" X-archive-position: 199 X-ecartis-version: Ecartis v1.0.0 Sender: kdb-bounce@oss.sgi.com Errors-to: kdb-bounce@oss.sgi.com X-original-sender: sonic.zhang@intel.com Precedence: bulk X-list: kdb Hi, You can download KDB v2.5 for kernel 2.4.20 at: ftp://oss.sgi.com/projects/kdb/download/v2.5/ Sonic Zhang -----Original Message----- From: lucipher [mailto:lucipher@promisc.org] Sent: 2002?12?22? 0:08 To: kdb@oss.sgi.com Subject: kdb for 2.4.20 Hello, Is kdb for 2.4.19 compatible with Linux 2.4.20 ?
