A kernel debugger is a debugger present in some kernels to ease debugging and kernel development by the kernel developers. A kernel debugger might be a stub implementing low-level operations, with a full-blown debugger such as gdb, running on another machine, sending commands to the stub over a serial line or a network connection, or it might provide a command line that can be used directly on the machine being debugged. Operating systems and operating system kernels that contain a kernel debugger: * The Windows NT family includes a kernel debugger named KD,〔(【引用サイトリンク】url=http://msdn.microsoft.com/en-us/library/ff551837.aspx )〕 which can act as a local debugger with limited capabilities (reading and writing kernel memory, but not setting breakpoints)〔(【引用サイトリンク】url=http://msdn.microsoft.com/en-us/library/ff553382(v=VS.85).aspx )〕 and can attach to a remote machine over a serial line, IEEE 1394 connection, USB 2.0 or USB 3.0 connection.〔(【引用サイトリンク】url=http://msdn.microsoft.com/en-us/library/windows/hardware/ff551063(v=vs.85).aspx )〕 The WinDbg GUI debugger can also be used to debug kernels on local and remote machines. * BeOS * DragonFly BSD * Linux kernel; No kernel debugger was included in the mainline Linux tree prior to version 2.6.26-rc1 because Linus Torvalds didn't want a kernel debugger in the kernel.〔(【引用サイトリンク】 url=http://lwn.net/2000/0914/a/lt-debugger.php3 )〕 * * KDB (local) * * KGDB (remote) * NetBSD (DDB for local, KGDB for remote) * OS X, Darwin which runs the XNU kernel using the Mach component ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「kernel debugger」の詳細全文を読む スポンサード リンク
