EFI_DEBUG_SUPPORT_PROTOCOL
Summary
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.

Parameters
Isa Declares the processor architecture for this instance of the EFI Debug
Support protocol.
GetMaximumProcessorIndex
Returns the maximum processor index value that may be used with
RegisterPeriodicCallback() and
RegisterExceptionCallback() . See the
GetMaximumProcessorIndex() function description.
RegisterPeriodicCallback
Registers a callback function that will be invoked periodically and
asynchronously to the execution of EFI. See the
RegisterPeriodicCallback() function description.
RegisterExceptionCallback
Registers a callback function that will be called each time the
specified processor exception occurs. See the
RegisterExceptionCallback() function description.
