It makes Linux Kernel supply a GDB remote debug interface. Then GDB in current machine or remote machine (see https://code.google.com/p/kgtp/wiki/HOWTO#Make_GDB_connect_to_gtp) can debug and trace Linux through GDB tracepoint 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 https://code.google.com/p/kgtp/wiki/HOWTO#Offline_debug). And it can work with Android (See https://code.google.com/p/kgtp/wiki/HowToUseKGTPinAndroid). Now, it supports X86-32, X86-64, MIPS and ARM. Now, KGTP 20111218 release. You can get the package for it from http://kgtp.googlecode.com/files/kgtp_20111218.tar.bz2 or svn co https://kgtp.googlecode.com/svn/tags/20111218 The change of this release is: Add gtp_rb to be the new frame buffer to make trace record speed up and more friendly to the older version Linux kernel. Rename gtp.patch to gtp_for_review.patch. Add Linux Kernel patch gtp_3.0_to_upstream.patch(3.0 to upstream), gtp_2.6.39.patch(2.6.39), gtp_2.6.33_to_2.6.38.patch(2.6.33 to 2.6.38) and gtp_older_to_2.6.32.patch(older to 2.6.32). Then you can include KGTP in your Kernel source tree. Add special trace state variable $gtp_version to show the version of KGTP. Fix some build errors of gtp_for_review.patch. Fix some build errors in ARM. Update doc. To get other change info please goto https://code.google.com/p/kgtp/wiki/UPDATE According to the comments of Christoph. I make a patch for Linux Kernel and make it looks OK with checkpatch.pl. The file gtp_for_review.patch is include in the source of KGTP code. Thanks, Hui
