From 6e0dcca8a9676834e327681abedbeca81a0907f2 Mon Sep 17 00:00:00 2001 From: marcel Date: Sat, 10 Jul 2004 17:47:22 +0000 Subject: Introduce the GDB debugger backend for the new KDB framework. The backend improves over the old GDB support in the following ways: o Unified implementation with minimal MD code. o A simple interface for devices to register themselves as debug ports, ala consoles. o Compression by using run-length encoding. o Implements GDB threading support. --- sys/gdb/gdb.h | 62 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 sys/gdb/gdb.h (limited to 'sys/gdb/gdb.h') diff --git a/sys/gdb/gdb.h b/sys/gdb/gdb.h new file mode 100644 index 0000000..a7a5429 --- /dev/null +++ b/sys/gdb/gdb.h @@ -0,0 +1,62 @@ +/* + * Copyright (c) 2004 Marcel Moolenaar + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * + * 1.
