When kgdb is enabled in the kernel config you can also elect to
enable the config parameter KGDB_TESTS. Turning this on will
enable a special kgdb I/O module which is designed to test the
kgdb internal functions.
</p><p>
The kgdb tests are mainly intended for developers to test the kgdb
internals as well as a tool for developing a new kgdb architecture
specific implementation. These tests are not really for end users
of the Linux kernel. The primary source of documentation would be
to look in the drivers/misc/kgdbts.c file.
</p><p>
The kgdb test suite can also be configured at compile time to run
the core set of tests by setting the kernel config parameter
KGDB_TESTS_ON_BOOT. This particular option is aimed at automated
regression testing and does not require modifying the kernel boot
config arguments. If this is turned on, the kgdb test suite can
be disabled by specifying "kgdbts=" as a kernel boot argument.
