From gdb stub mode you can blindly type\n\"$3#33\", or from the kdb mode you can enter \"kgdb\" to switch to the\ngdb stub.\n\nThe logic in the debug core depends on kdb to look for the typical gdb\nconnection sequences and return immediately with KGDB_PASS_EVENT if a\ngdb serial command sequence is detected. That should allow a\nreasonably seamless transition between kdb -\u003e gdb without leaving the\nkernel exception state. The two gdb serial queries that kdb is\nresponsible for detecting are the \"?\" and \"qSupported\" packets.\n\nCC: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nAcked-by: Martin Hicks \u003cmort@sgi.com\u003e\n" }, { "commit": "5d5314d6795f3c1c0f415348ff8c51f7de042b77", "tree": "2f433649d29be98ebc975f352b7d7046a2a2beec", "parents": [ "e8861129d3c1a64e3c62f459aeb1cd54a55ab045" ], "author": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Thu May 20 21:04:20 2010 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Thu May 20 21:04:20 2010 -0500" }, "message": "kdb: core for kgdb back end (1 of 2)\n\nThis patch contains only the kdb core. Because the change set was\nlarge, it was split. The next patch in the series includes the\ninstrumentation into the core kernel which are mainly helper functions\nfor kdb.\n\nThis work is directly derived from kdb v4.4 found at:\n\nftp://oss.sgi.com/projects/kdb/download/v4.4/\n\nThe kdb internals have been re-organized to make them mostly platform\nindependent and to connect everything to the debug core which is used by\ngdbstub (which has long been known as kgdb).\n\nThe original version of kdb was 58,000 lines worth of changes to\nsupport x86. From that implementation only the kdb shell, and basic\ncommands for memory access, runcontrol, lsmod, and dmesg where carried\nforward.\n\nThis is a generic implementation which aims to cover all the current\narchitectures using the kgdb core: ppc, arm, x86, mips, sparc, sh and\nblackfin. More archictectures can be added by implementing the\narchitecture specific kgdb functions.\n\n[mort@sgi.com: Compile fix with hugepages enabled]\n[mort@sgi.com: Clean breakpoint code renaming kdba_ -\u003e kdb_]\n[mort@sgi.com: fix new line after printing registers]\n[mort@sgi.com: Remove the concept of global vs. local breakpoints]\n[mort@sgi.com: Rework kdb_si_swapinfo to use more generic name]\n[mort@sgi.com: fix the information dump macros, remove \u0027arch\u0027 from the names]\n[sfr@canb.auug.org.au: include fixup to include linux/slab.h]\n\nCC: linux-arch@vger.kernel.org\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nSigned-off-by: Martin Hicks \u003cmort@sgi.com\u003e\n" }, { "commit": "53197fc49549240f6c6a963b2713a4cd9517964b", "tree": "5a89c338ef8acd188e4aa1503370a4e928c33edd", "parents": [ "c433820971ffa854feda6adc17f5f24201354f11" ], "author": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Apr 02 11:48:03 2010 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Thu May 20 21:04:19 2010 -0500" }, "message": "Separate the gdbstub from the debug core\n\nSplit the former kernel/kgdb.c into debug_core.c which contains the\nkernel debugger exception logic and to the gdbstub.c which contains\nthe logic for allowing gdb to talk to the debug core.\n\nThis also created a private include file called debug_core.h which\ncontains all the definitions to glue the debug_core to any other\ndebugger connections.\n\nCC: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\n" }, { "commit": "c433820971ffa854feda6adc17f5f24201354f11", "tree": "efb8028cc56e36eeade40d3a96bb461a242bab51", "parents": [ "a0fe3cc5d36a5f5b4f60abfe1a4b1caf4a5cce5a" ], "author": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Tue May 19 07:49:32 2009 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Thu May 20 21:04:18 2010 -0500" }, "message": "Move kernel/kgdb.c to kernel/debug/debug_core.c\n\nMove kgdb.c in preparation to separate the gdbstub from the debug\ncore and exception handling.\n\nCC: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\n" } ] }
