Detailed Description
This module contains all RTEMS Configuration parameters.
This modules includes configuration parameters for applications which use GCC Go.
This modules includes configuration parameters for applications which use GNAT/RTEMS.
This module contains the parameters related to the Multiprocessing configuration of RTEMS.
This module contains parameters related to the LIBBLOCK buffering and caching subsystem.
This group contains parameters related to generating a Device Driver Table.
This group contains the elements needed to define the Classic API Initialization Tasks Table.
This module contains parameters related to thread aand interrupt stacks.
This module contains configuration parameters related to the set of IDLE threads.
The model is to estimate the memory required for each configured item and sum those estimates. The estimate can be too high or too low for a variety of reasons:
Reasons estimate is too high:
- FP contexts (not all tasks are FP)
Reasons estimate is too low:
- stacks greater than minimum size
- messages
- application must account for device driver resources
- application must account for add-on library resource requirements
NOTE: Eventually this may be able to take into account some of the above. This procedure has evolved from just enough to support the RTEMS Test Suites into something that can be used remarkably reliably by most applications.
On a uniprocessor system, there is one IDLE thread. On an SMP system, there is one for each core.
Default User Initialization Task Table. This table guarantees that one user initialization table is defined.
Default Device Driver Table. Each driver needed by the test is explicitly choosen by the application. There is always a null driver entry.
It requires tasks to swap out data to be written to non-volatile storage.
In a single processor or SMP configuration, only two parameters are needed and they are defaulted. The user should not have to specify any parameters.
GNAT implements each Ada task as a POSIX thread.
