Hi guys, KGTP is a flexible , lightweight and realtime Linux debugger and tracer. To use it, you don't need patch or rebuild the Linux kernel. Just build KGTP module and insmod it is OK.
It makes Linux Kernel supply a GDB remote debug interface. Then GDB in current machine or remote machine can debug and trace Linux through GDB tracepoint and some other functions without stopping the Linux Kernel. And even if the board doesn't have GDB on it and doesn't have interface for remote debug. It can debug the Linux Kernel using offline debug (See http://code.google.com/p/kgtp/wiki/HOWTO#/sys/kernel/debug/gtpframe_and_offline_debug). KGTP supports X86-32, X86-64, MIPS and ARM. KGTP is tested on Linux kernel 2.6.18 to upstream. And it can work with Android (See http://code.google.com/p/kgtp/wiki/HowToUseKGTPinAndroid). Please go to http://code.google.com/p/kgtp/wiki/HOWTO or http://code.google.com/p/kgtp/wiki/HOWTO (Chinese) to get more info about howto use KGTP. Now, KGTP 20120920 release. You can get the package for it from http://kgtp.googlecode.com/files/kgtp_20120920.tar.bz2 or svn co https://kgtp.googlecode.com/svn/tags/20120920 The main change of this release is: C plugin support. With this function, you can dynamic add new function to KGTP with LKM. To get more info about it. Please goto http://code.google.com/p/kgtp/wiki/HOWTO#How_to_add_plugin_in_C Per_cpu trace state variables function was updated. The usage and format was changed. This change make it more easy to be used. And I also update the doc to make it more clear. Please goto http://code.google.com/p/kgtp/wiki/HOWTO#Per_cpu_trace_state_variables get it. Please goto http://code.google.com/p/kgtp/wiki/UPDATE get more info about this release. According to the comments of Christoph, Geoff and Andi. I make lite patch for review. Please goto https://lkml.org/lkml/2012/5/9/90 to see it.
