HP Kernel Debugger (KWDB)
The HP Kernel Debugger (KWDB) is a source-level kernel and driver debugger for the
HP-UX operating system. KWDB is based on the HP Wildebeest Debugger (WDB), an
HP-supported implementation of the GDB user-space debugger. It also incorporates all
the features of Q4, a crash dump and live memory analyzer.
NOTE Although KWDB is included in HP-UX 11i v2, HP does not provide support for it.
Summary of Change
KWDB includes the following features:
• Support for debugging 32-bit and 64-bit HP-UX kernels
• Support for debugging dynamically loadable kernel modules (DLKM)
• Support for MP debugging
