/* 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.
