GameShop Debugger

WorkShop Debugger Heritage
The GameShop debugger (gvd) derived its heritage from the Silicon Graphics WorkShop application development tools. It is a source level windowing debugger environment that enables debugging of both the CPU and RSP software.

Debugger Components
The debugger is actually composed of several different components shown in Figure 4.8.1, below.

There are two debugging paths. The first path is a C source level windowing debugger, gvd, which has most of the features of common multi-threaded debuggers. It talks to dbgif, which interfaces to the rmon debug thread through the Nintendo 64 device driver in IRIX.

The second path is the popular printf traces within the application. rmonPrintf() display the messages in the shell that executed dbgif.

Figure 4.8.1 Debugger Components

The rmon debugger thread is actually a high-priority thread in the game application and uses many operating system resources. Therefore, the debugger and rmonPrintf cannot be used to debug system-level code.
