2	* @file rtems/confdefs.h
3	*
4	* This include file contains the configuration table template that will
5	* be instantiated by an application based on the setting of a number
6	* of macros. The macros are documented in the Configuring a System
7	* chapter of the Classic API User's Guide
8	*
9	* The model is to estimate the memory required for each configured item
10	* and sum those estimates. The estimate can be too high or too low for
11	* a variety of reasons:
12	*
13	* Reasons estimate is too high:
14	* + FP contexts (not all tasks are FP)
15	*
16	* Reasons estimate is too low:
17	* + stacks greater than minimum size
18	* + messages
19	* + application must account for device driver resources
20	* + application must account for add-on library resource requirements
21	*
22	* NOTE: Eventually this may be able to take into account some of
23	* the above. This procedure has evolved from just enough to
24	* support the RTEMS Test Suites into something that can be
25	* used remarkably reliably by most applications.

542	* By reducing the number of priorities in a system,
