* All task delete API level services were incorrectly assuming that theJoel Sherrill1998-06-181-1/+10
| | | | | | | | | | | 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.

* Big patch form Ralf Corsepius described in this email:Joel Sherrill1998-01-301-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is the result of my nightly work to get RTEMS_ROOT=$srcdir working with different shells and relative/absolute paths. What I did is relatively simple in principle: Instead of setting RTEMS_ROOT in configure.in and then let configure substitute @RTEMS_ROOT@ inside the Makefiles, I now let each Makefile set RTEMS_ROOT from each Makefile's @top_srcdir@ value. The difference is subtile, but with enormous side effects: - If RTEMS_ROOT is set in configure, then the same single value will be propagated to all Makefiles. This breaks using relative paths, as the relative path to the root of the source tree is used inside of all subdirectory Makefiles. - Now each Makefile.in sets RTEMS_ROOT = @top_srcdir@. top_srcdir is computed individually by configure for each single Makefile.in, hereby receiving the correct value, no matter if relative or absolute paths are used. To get this working, I needed to remove setting RTEMS_ROOT from target.cfg.in, because this overrides the value of RTEMS_ROOT from each individual Makefile. Furthermore, I removed RTEMS_CUSTOM from the Makefiles and replaced all "include $(RTEMS_CUSTOM)" directives with"include $(RTEMS_ROOT)/make/custom/$(RTEMS_BSP)". Perhaps you don't like this, but I think, to have one variable less is clearer and easier to understand than having several variables refering to the next one. I enclose a small patch to this mail, which - fixes the config.h problem (to finally clearify misunderstands) - removes assignment/subsitution of RTEMS_ROOT from configure.in - contains a workaround for the application Makefile's RTEMS_ROOT problem (reported by Eric) - removes some unused lines from the toplevel Makefile.in - removes assignment of RTEMS_ROOT from make/target.cfg.in

* This set of changes is the build of what was required to convert toJoel Sherrill1997-04-011-0/+40
| | | | | | | | | | | | | | | | | | | | GNU autoconf. This is the first large step in allowing an RTEMS user to perform a one-tree build (per crossgcc FAQ) including RTEMS in the build process. With this change RTEMS is configured in built in the same style as the GNU tools, yet retains the basic structure of its traditional Makefiles (ala Tony Bennett). Jiri Gaisler (jgais@wd.estec.esa.nl) deserves (and received) a big thank you for doing this. There are still issues to be resolved but as of this commit, all target which can be built on a linux host have been using a modified version of the source Jiri submitted. This source was merged and most targets built in the tree before this commit. There are some issues which remain to be resolved but they are primarily related to host OS dependencies, script issues, the use of gawk for hack_specs, and the dependence on gcc snapshots. These will be resolved.
* Modified calls to _Thread_Change_priority to take a third argument. The newJoel Sherrill1997-03-081-1/+1
| | | | | | | | | | | | 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.
* Suggested changes from Mark Jordan which eliminate warnings and errorsJoel Sherrill1996-12-026-12/+16
| | | | | | | | he received using the Microtec C++ compiler. Most of these are either missing casts from/to (void *), heavy handed use of enumerated types, or simply assumed conversions. There is at least one actual bug in an error path in thread.c in which the wrong argument was passed to _Thread_Stack_Free and was not being caught by gcc.
* changed _TOD_Is_set from a function to a boolean variableJoel Sherrill1996-09-065-9/+9
|
* Added Sporadic Server support to posix threads which required changesJoel Sherrill1996-06-061-4/+16
| | | | | in the core to support multiple algorithms to handle cpu time budgetting which resulted in a change to the calling sequence of _Thread_Initialize.
* added priority ceiling supportJoel Sherrill1996-06-031-1/+2
|
* renamed _TOD_Ticks_since_boot as _Watchdog_Ticks_since_boot so the WatchdogJoel Sherrill1996-05-312-2/+2
| | | | | Handler could timestamp the starting and stopping of timers. Since TOD is built on top of Watchdog, this avoided a circular dependency.

* The word "RTEMS" almost completely removed from the core.Joel Sherrill1995-09-1122-858/+1205
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Added unused priority ceiling parameter to rtems_semaphore_create.Joel Sherrill1995-08-2813-139/+157
| | | | | | | | | | | | | | | 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.
* Moved _Thread_Information -> _RTEMS_tasks_Information.Joel Sherrill1995-08-2310-15/+51
| | | | | | | 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.
* Support for variable length names added to Object Handler. This supportsJoel Sherrill1995-08-2314-87/+123
| | | | | | both fixed length "raw" names and strings from the API's point of view. Both inline and macro implementations were tested.

* + Added object type field to object id.Joel Sherrill1995-08-189-2/+9
| | | | | | | | | | + 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
