* This set of changes is the build of what was required to convert toJoel Sherrill1997-04-011-0/+41
| | | | | | | | | | | | | | | | | | | | 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 Sherrill1997-03-082-10/+39
| | | | | | | | | 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.
* added some casts to reduce warnings reported by users with Microtec C++Joel Sherrill1997-01-084-28/+35
| | | | compiler.
* added support for cpu time used field in tcbJoel Sherrill1996-10-151-0/+16
|
* loop to clear workspace memory changed to use sizeof rather thanJoel Sherrill1996-09-181-1/+1
| | | | hardcoded 4 to be compatible with CPUs with 64-bit ints
* corrected prototype of _Objects_Get_nextJoel Sherrill1996-09-181-1/+1
|
* uses address object rather than direct pointer arithmeticJoel Sherrill1996-09-181-2/+3
|
* Reversed logic in conditional to correctly distinguish betweenJoel Sherrill1996-09-171-2/+2
| | | | FIFO and priority disciplines.
* changed _TOD_Is_set from a function to a boolean variableJoel Sherrill1996-09-062-0/+8
|
* _Thread_Start_multitasking: added code to initialize the floating pointJoel Sherrill1996-08-151-1/+25
| | | | context of the first thread to execute.
* fixed spacingJoel Sherrill1996-08-131-2/+2
|
* _MPCI_Register_packet_processor: changes first parameter type to ↵Mark Johannes1996-08-081-1/+1
| | | | MP_packet_Classes
* _CORE_Mutex_seize: added checks for priority ceiling violation, also addedMark Johannes1996-08-071-6/+24
| | | | checks to ensure priority was not lowered.
* _CORE_mutex_Seize: added change priority case if the mutex was obtained.Mark Johannes1996-08-061-0/+12

* Added code so post context switch extensions can be run on every contextJoel Sherrill1996-06-131-2/+5
| | | | switch. This was needed to support process wide signals.
* added code to _Thread_Clear_state to check if the state was not currently set.Joel Sherrill1996-06-101-13/+19
|
* Added Sporadic Server support to posix threads which required changesJoel Sherrill1996-06-062-27/+51
| | | | | 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 cpu_time_budget field to Thread_Control and removed the global variableJoel Sherrill1996-06-051-4/+3
| | | | _Thread_Ticks_remaining_in_timeslice.
* fixed spacingJoel Sherrill1996-06-051-1/+1
|
* added support for the api providing the thread stack areaJoel Sherrill1996-06-051-23/+33
|
* added priority ceiling supportJoel Sherrill1996-06-031-32/+61
|
* renamed _TOD_Ticks_since_boot as _Watchdog_Ticks_since_boot so the WatchdogJoel Sherrill1996-05-313-2/+6
| | | | | Handler could timestamp the starting and stopping of timers. Since TOD is built on top of Watchdog, this avoided a circular dependency.
* spacingJoel Sherrill1996-05-291-0/+1
|
* changed call to _ISR_Enable() to _ISR_Set_level() in _Thread_Handler.Joel Sherrill1996-05-281-1/+1
| | | | | _ISR_Enable() takes the magic cookie expected by the cpu's status register instead of a simple isr level.
* invoke thread stack free routine instead of Workspace free.Joel Sherrill1996-05-231-2/+26
|
* added comment regarding stack alignment issues to thread stack allocationJoel Sherrill1996-04-241-0/+14
| | | | routine.
* thread.c: added support for optional user provided stack allocatorJoel Sherrill1996-04-222-8/+123
| | | | wkspace.c: made initialization routine a regular subroutine
* *** empty log message ***Joel Sherrill1996-03-211-4/+4
|
* Removed the internal thread objects and dispersed its contents toJoel Sherrill1996-02-212-7/+286
| | | | | | | | | | the thread handler (IDLE), MPCI object (SYSI now MP Receive) and initialize_executive_early (IO initialization). The SYSI task no longer exists in a single processor configuration. This reduces single processor Workspace requirements by a TCB and a stack which is often larger than the minimum stack size. Moving the IO initialization plus accompanying BSP hooks eliminated an initialization ordering problem in which a global task could be created before the MPCI was initialized.
* removed arguments from _Thread_Start_multitaskingJoel Sherrill1996-02-141-12/+10
|
* white space problemJoel Sherrill1996-02-141-1/+0
|
* changed post task extension from user set to api set and added flagJoel Sherrill1996-02-132-1/+27
| | | | in each thread which must be set when the post switch extension is to be run.
* more comments added and existing ones cleaned up in synchronization pathsJoel Sherrill1996-02-131-1/+13
|
* new isr synchronization algorithm using a single enumerated set of states.Joel Sherrill1996-02-091-42/+73

* Swapped order of nested acquisition check and check for returning unsatisfied.Joel Sherrill1996-02-011-6/+6

* synchronization state bugs addressJoel Sherrill1996-02-011-7/+12
|
* invalid use of tcb field resource countJoel Sherrill1996-02-011-1/+0
|
* Made real body of _Heap_Walk conditional on RTEMS_DEBUG. This is necessaryJoel Sherrill1996-01-151-0/+13
| | | | to be able to build a system without requiring printf.
* added correct use of _Thread_queue_Enter_critical_sectionJoel Sherrill1995-12-084-4/+4
|
* Insert mode argument to _Watchdog_Insert removed. Now are watchdog timersJoel Sherrill1995-12-014-16/+8
| | | | are automatically activated upon insertion.
* Added new synchronization algorithm.Joel Sherrill1995-12-011-58/+92
|
* Corrected use of the state WATCHDOG_REINSERT and renamed itJoel Sherrill1995-12-011-6/+19

* SPARC port passes all testsJoel Sherrill1995-10-301-1/+5
|
* all targets compile .. tony's patches in placeJoel Sherrill1995-09-291-2/+13
|
* posix support initially addedJoel Sherrill1995-09-2619-90/+89
|
* Removed unnecessary include files.Joel Sherrill1995-09-221-1/+1
