I am porting the MIPS/Linux version of the Linux kernel to a IDT79S145 
evaluation
board.  This board has a
IDT64475 (MIPS).  I would like to use a standard serial port as a kgdb port.  I
will use my other serial port for the
console port.  Could you provide any additional information regarding the kgdb
interface?   Is kgdb a standalone
application that would need to be built on the host to access a target board or 
is
it a patch to the kernel files that needs
to built into the kernel running on the host?

Jeff
