Kernel debugger

Kernel debugger

A kernel debugger is a debugger present in some kernels to ease debugging and kernel development by the kernel developers.

*The Windows NT family of operating systems contain a kernel debugger.
*BeOS contain a kernel debugger.
*DragonFly BSD employs a built-in kernel debugger.

No kernel debugger was included in the mainline Linux kernel tree prior to version 2.6.26-rc1 because Linus Torvalds didn't want a kernel debugger in the kernel. cite web | title=LWN.net | url=http://lwn.net/2000/0914/a/lt-debugger.php3 | accessdate=2008-05-29] [ [http://lwn.net/Articles/280912/ 3rd may 2008 : Message from Linus Torvalds for the 2.6.26-rc1 kernel merge] ]

KGDB and KDB are two kernel debuggers for the Linux kernel. KGDB requires an additional machine for debugging, whereas KDB allows the kernel to be debugged on the same machine while the kernel is running. cite web | last=Nellitheertha | first=Hariprasad | title=Inside the Linux kernel debugger | url=http://www.ibm.com/developerworks/linux/library/l-kdbug/index.html | accessdate=2008-05-29] . The debugger included in Linux is KGDB.
