* Moved i386 and m68k cache management code to libcpu. EverythingJoel Sherrill2000-06-131-140/+0
| | | | | | now is an implementation of the prototypes in rtems/rtems/cache.h. The libcpu/i386/wrapup directory is no longer needed. The PowerPC needs this done to it.

| | | | | | | | | | | | | | | <charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart <Darlene.Stewart@nrc.ca> to add support for a number of very significant things: + BSPs for many variations on the Motorola MBX8xx board series + Cache Manager including initial support for m68040 and PowerPC + Rework of mpc8xx libcpu code so all mpc8xx CPUs now use same code base. + Rework of eth_comm BSP to utiltize above. John reports this works on the 821 and 860

* Patch from Eric Norum <eric@cls.usask.ca> to implement this:Joel Sherrill2000-01-211-2/+3
| | | | | | | | | | | | | | | | | | | | 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.
* Added support for simple binary semaphores in addition to the highJoel Sherrill2000-01-051-7/+6
| | | | | | | | | | | | power binary/mutex style semaphores already supported by RTEMS. This was done at the request of Eric Norum <eric@cls.usask.ca> in support of his effort to port EPICS to RTEMS. This change consisted of changing the nesting_allowed boolean into a lock_nesting_behavior enumerated value as well as allowing the core mutex object to optionally support ensuring that the holder of a binary semaphore released it. Finally, a more subtle enhancement was to allow the non-holder to release a priority inheritance/ceiling mutex and still allow the holding task to return to its original priority.
* First attempt at adding simple binary semaphore in addition to the currentJoel Sherrill1999-12-131-1/+5
| | | | | "mutex" and counting semaphore. This is at the request of Eric Norum and his EPICS porting effort.
* Patch rtems-rc-19991123-rc-0.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1999-11-291-0/+14
| | | | | | | | | | | | | | | | | | | | | | | which (among other things) converted the mptests to automake. SUB_DIRS was used instead of SUBDIRS in some Makefile.ins (apparently a leftover from moving the start* directories) Addtional major bugs: * psxtests/include was empty (incomplete psxtests changes). * bogus handling of *.scn in itrontests (screens/sptests vs. screens/itrontests installation dirs) In addition I have added a few more changes (I couldn't resist) * automake support for itrontests * OPERATION_COUNT support in tmitrontests/ * automake support for tmitrontests * automake suppport for mptests * Some (minor) corrections to several configure.in/Makefile.ams => c/src/tests/ is completly under automake control, now. => we could start to sort out the structural issues with c/src/tests (tests/support, stubdr, tools, get "make dist" working)

* Moved task_variable pointer to basic shared part of TCB instead ofJoel Sherrill1999-11-161-15/+0
| | | | | | | 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.

* Suggested changes from Mark Jordan which eliminate warnings and errorsJoel Sherrill1996-12-021-2/+3
| | | | | | | | 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.
* split the inclusion of "EXTERN" data based on whether it was sapi,Joel Sherrill1996-05-2810-12/+13

* event.h: _Event_Manager_initialization no longer a static inlineJoel Sherrill1996-04-192-0/+12
| | | | support.h: updated to use RTEMS_APPLICATION macro
* Removed prototyes for static inline routines and moved the comments intoJoel Sherrill1996-03-0616-1031/+34
| | | | | | | | | | | | | | | the inline implementation. The impetus for this was twofold. First, it is incorrect to have static inline prototypes when using the macro implementation. Second, this reduced the number of lines in the include files seen by rtems.h by about 2000 lines. Next we restricted visibility for the inline routines to inside the executive itself EXCEPT for a handful of objects. This reduced the number of include files included by rtems.h by 40 files and reduced the lines in the include files seen by rtems.h by about 6000 lines. In total, these reduced the compile time of the entire RTEMS tree by 20%. This results in about 8 minutes savings on the SparcStation 10 morgana.

* The word "RTEMS" almost completely removed from the core.Joel Sherrill1995-09-1129-204/+519
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Sherrill1995-08-287-32/+62
| | | | | | | | | | | | | | | 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 Sherrill1995-08-231-0/+19
| | | | | | | 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 Sherrill1995-08-2317-44/+188
| | | | | | both fixed length "raw" names and strings from the API's point of view. Both inline and macro implementations were tested.
