/* Profiling SCOPE
* ---------------
* PT_SYSTEM
* Profile the ENTIRE system;
* Exists for the use of tools like PSET, which gather data on
* system behavior. Avoids need to write/modify test programs.
*
* PT_USER (i.e., PT_SYSTEM not specified)
* Profile ONLY in the context of the calling process;
* Exists to gather data on an individual program and those parts of
* the system exercised by that program.
*
* Profiling Configuration
* -----------------------
* PT_USEDD
* Call PROFILE device driver, if installed, on every timer tick.
* Used by Presentation Manager "attributed" profiling, in
* particular. Allows for arbitrary actions at "profile" time.
*
* PT_USEKP
* Cause kernel to record profiling information;
* These are the 4-byte granularity tick counts kept for each
* code segment of interest. Making this optional allows one to
* do PT_USEDD profiling without taking the memory hit of Kernel
* Profiling.
*
* PT_VERBOSE
* Collect detailed tick counts on KERNEL code segments;
* Works only if PT_USEKP also specified. Generally useful
* only for kernel programmers tuning the kernel.
*
*
* The above flags can be used in any combination, with the exception
* that PT_VERBOSE is allowed only if PT_USEKP is also specified.
