I'd like to try kdb, but I can't seem to make it work. If its as good as the FreeBSD/NetBSD ddb, I'd rather just use it than gdb. However, I can't seem to make it work. % nvram boot-args boot-args -v debug=0x11e However, when I send a break, it still ends up waiting for kdp. I've gone so far as to attempt to switch manually: (gdb) p *( int *)&current_debugger $1 = 1 (gdb) p *( int *)&switch_debugger $2 = 0 (gdb) set *( int *)&switch_debugger=1 (gdb) set *( int *)&current_debugger=2 (gdb) c Continuing. Program received signal SIGTRAP, Trace/breakpoint trap. 0x00085ed4 in Debugger () <back in kdp, not kdb> Kdb seems to be present in the kernel: % nm /mach_kernel | grep kdb_trap 00085638 T _kdb_trap And I do have a serial console working. Any ideas? I suppose cross-building Apple's gdb on FreeBSD was worth it after all ;) > >0x100 turns off the graphical, multilingual panic screen, and reverts to > >the old text stack crawl.

Is there anyway to get rid of the nice, friendly "You need to restart your computer...." window which appears in 10.2 when a panic happens? Its blocking part of the register dump that I'd like to see.

I've just discovered that quiting gdb and attaching gdb a second time seems to work.

debugging crash on SMP systems
by Andrew Gallatin 30 Aug '02

30 Aug '02

My network driver is crashing an SMP system. CPU #1 is the first to crash, with my driver on the stack. CPU #0 then crashes slightly later (I'm assuming its collateral damage). When I attach via remote-kdb, I see the stack from CPU #1, presumably since it was the last to crash. Is there a way to switch to cpu #0 so I can see the stack there? Failing that, is there any easy way to disable the second CPU via software? (like a boot arg, or something in OpenFirmware..) FWIW, I'm using the binary kernel that comes with 10.2, so most of the gdb macros seem useless... :( Thanks, Drew _______________________________________________ darwin-kernel mailing list | darwin-kernel(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.

I just moved to Germany from LA, so a trip to Paris for a trade show would actually be kind of nice! -- j. -- Jay Vaughan Access Music jv(a)access-music.de >>music:technology:synthesizers - www.access-music.de/ _______________________________________________ darwin-kernel mailing list | darwin-kernel(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.

Re: darwin-kernel: is jaguar in cvs?

Joshua LeVasseur heeft op zondag, 25 aug 2002 om 11:58 (Europe/Amsterdam) het volgende geschreven: Is the xnu that shipped with Jaguar available in cvs? If so, anyone know the specific tag? What is the Darwin version number for the Jaguar release? (Sorry if this info is available somewhere, but I've hunted for it without success.) [loki:~] coolvibe% uname -a Darwin loki.ipv6.hackerheaven.org 6.0 Darwin Kernel Version 6.0: Sat Jul 27 13:18:52 PDT 2002; root:xnu/xnu-344.obj~1/RELEASE_PPC Power Macintosh powerpc This is from my OSX 10.2 machine (10.2 arrived on my doorstep yesterday.. yaaaay). So I guess that means you need the Apple-344 branch to get Darwin 6 xnu.

new xnu won't recognize ethernet card in PowerBook G3 FireWire
by JT Zemp 26 Aug '02

26 Aug '02

Hello all, I have a query and I'm not sure if I'm on the right list. I've recompiled xnu-201.5 and xnu-201-9.1 with Libstreams-23, cctools-10 and bootstrap_cmds-26. When I reboot into either of these kernels, everything goes ok, but I can't get my ethernet card to come up. If I copy the kernel over to another machine (G4 PowerMac) everything works fine on that machine. I'm running OS X 10.1.5 and using the April Developer tools.
