I'd like to propose a change to RTEMS task variables that I think would
make them more useful. I think that it is early enough in their
existence to still make changes to their API.
1) Change type from `int' to `void *'.
2) Add extra argument to task_variable_add -- if non-NULL, a pointer to
a `destructor' function to be called when the task exits. This function
would be called with that task's value of the task variable as its
argument. In many cases, the `dtor' function could be `free'.
rtems_status_code rtems_task_variable_add (
rtems_id tid, void **ptr, void (*dtor)(void *));
rtems_status_code rtems_task_variable_delete (rtems_id tid, void **ptr);
This would be all we'd need to cleanly and efficiently support C++
per-thread exception information without dragging in all that POSIX API
stuff.

RTEMS API extension to avoid problems when the extension is freed.
Eventually the task variable switch extension should become part
of the core context switch and the Ada tcb self implemented in
terms of it.

After being submitted, this support was rewritten to be inside the
executive rather than layered on top of it using an extension.

task to be deleted was created via the same API (i.e. were of the object
class created by this API). For example, a POSIX thread calling
the rtems_task_delete(SELF) directive would incorrectly update the RTEMS
object local pointer table.
Jennifer discovered this when moving tests implemented in C using the
Classic RTEMS API into a tree of Ada tests. The Ada tests were implicitly
using POSIX services. This lead to some unexpected behavior.

argument indicates whether the task is to be placed at the head or tail of
its priority fifo when it is lowering its own priority. POSIX normally
follows the RTEMS API conventions but GNAT expects that all lowering of
a task's priority by the task itself will result in being placed at the
head of the priority FIFO. Normally, this would only occur as the result
of lose of inherited priority.
The RTEMS API always puts tasks at the end of their priority group except
upon loss of inherited priority.

single biggest changes were the expansion of the workspace size
macro to include other types of objects and the increase in the
minimum stack size for most CPUs.

Configuration Table Template file added and all tests
modified to use this. All gvar.h and conftbl.h files
removed from test directories.
Configuration parameter maximum_devices added.
Core semaphore and mutex handlers added and RTEMS API Semaphore
Manager updated to reflect this.
Initialization sequence changed to invoke API specific initialization
routines. Initialization tasks table now owned by RTEMS Tasks Manager.
Added user extension for post-switch.
Utilized user extensions to implement API specific functionality
like signal dispatching.
Added extensions to the System Initialization Thread so that an
API can register a function to be invoked while the system
is being initialized. These are largely equivalent to the
pre-driver and post-driver hooks.
Added the Modules file oar-go32_p5, modified oar-go32, and modified
the file make/custom/go32.cfg to look at an environment varable which
determines what CPU model is being used.
All BSPs updated to reflect named devices and clock driver's IOCTL
used by the Shared Memory Driver. Also merged clock isr into
main file and removed ckisr.c where possible.
Updated spsize to reflect new and moved variables.
Makefiles for the executive source and include files updated to show
break down of files into Core, RTEMS API, and Neither.
Header and inline files installed into subdirectory based on whether
logically in the Core or a part of the RTEMS API.

Rearranged code to created thread handler routines to initialize,
start, restart, and "close/delete" a thread.
Made internal threads their own object class. This now uses the
thread support routines for starting and initializing a thread.
Insured deleted tasks are freed to the Inactive pool associated with the
correct Information block.
Added an RTEMS API specific data area to the thread control block.
Beginnings of removing the word "rtems" from the core.
|
| |
|
|
|
|
|
| |
Added a table of object information control blocks.
Modified _Thread_Get so it looks up a thread regardless of which
thread management "entity" (manager, internal, etc) actually "owns" it.
|
| |
|
|
|
|
| |
both fixed length "raw" names and strings from the API's point of view.
Both inline and macro implementations were tested.

+ Added name pointer to Object_Control.
+ Modified Object Open and Close to address name field.
+ Removed name as separate element from Thread and Proxy Control.
+ Added parameter "object class" to calls to Initialize Information
