   The DebugSupport protocol is used by source level debuggers to abstract the
   processor and handle context save and restore operations.

+/**
+  @par Protocol Description:
+  This protocol provides the services to allow the debug agent to register 
+  callback functions that are called either periodically or when specific 
+  processor exceptions occur.
+
+  @param Isa
+  Declares the processor architecture for this instance of the EFI
+  Debug Support protocol.
+
+  @param GetMaximumProcessorIndex
+  Returns the maximum processor index value that may be used.
+
+  @param RegisterPeriodicCallback
+  Registers a callback function that will be invoked periodically
+  and asynchronously to the execution of EFI.
+
+  @param RegisterExceptionCallback
+  Registers a callback function that will be called each time the
+  specified processor exception occurs.
+
+  @param InvalidateInstructionCache
+  Invalidate the instruction cache of the processor. This is required
+  by processor architectures where instruction and data caches are
+  not coherent when instructions in the code under debug has been
+  modified by the debug agent.
