* Added base version of file system infrastructure. This includes a majorJoel Sherrill1998-11-232-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | overhaul of the RTEMS system call interface. This base file system is the "In-Memory File System" aka IMFS. The design and implementation was done by the following people: + Joel Sherrill (joel@OARcorp.com) + Jennifer Averett (jennifer@OARcorp.com) + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com) + Kerwin Wade (wade@OARcorp.com) PROBLEMS ======== + It is VERY likely that merging this will break the UNIX port. This can/will be fixed. + There is likely some reentrancy/mutual exclusion needed. + Eventually, there should be a "mini-IMFS" description table to eliminate links, symlinks, etc to save memory. All you need to have "classic RTEMS" functionality is technically directories and device IO. All the rest could be left out to save memory.
* Added --disable-multiprocessing flag and modified a lot of files to makeJoel Sherrill1998-11-237-17/+84
| | | | it work.
* Patch from Eric Norum <eric@skatter.usask.ca>:Joel Sherrill1998-11-191-1/+1
| | | | | | | | | | | | | | | 1) Socket timeout field changed from `short' to `long'. This makes longer timeouts possible. With a 1 kHz system clock the old system allowed timeouts only up to a little over 30 seconds! This change is a slightly cleaned-up version of the patch proposed by Ian Lance Taylor. 2) Major changes to BOOTP/DHCP reply handling. Now supports much of RFC2132. These changes were done at the request of, and with the assistance of, Erik Ivanenko. If you're making changes, you might want to change the network supplement Essentially just do a global search and replace of BOOTP with BOOTP/DHCP.

* Added ENOSYS stubs for a number of process routines.Joel Sherrill1998-09-258-0/+132

* All task delete API level services were incorrectly assuming that theJoel Sherrill1998-06-181-1/+5
| | | | | | | | | | | 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.
* Moved POSIX_signals_Siginfo_node structure definition to headers/psignal.hJoel Sherrill1998-04-271-5/+1
| | | | so confdefs.h could see it.
* Changed __POSIX_SIGNALS_h to __RTEMS_POSIX_SIGNALS_h to avoid conflict withJoel Sherrill1998-04-271-2/+7
| | | | | | | the system signals.h file. Moved POSIX_signals_Siginfo_node type definition to this file to allow confdefs.h to know the size per queued signal.
* Made these have real constants.Joel Sherrill1998-04-031-6/+6

* updated copyright to 1998Joel Sherrill1998-02-1721-21/+21
|
* Fixed typo in the pointer to the license terms.Joel Sherrill1997-10-0821-42/+42
|
* Added _Thread_Enable_dispatch to already_timedout path on Wait_support.Joel Sherrill1997-10-061-2/+3
|
* If the specified time period is less than a clock tick, thenJoel Sherrill1997-10-051-1/+4
| | | | it is arbitrarily assumed to be 1 clock tick.
* Fixed infinite recursion bug in PTHREAD_MUTEX_INITIALIZER.Joel Sherrill1997-08-221-10/+15
|
* Added commit about missing support for condition initializer.Joel Sherrill1997-08-221-0/+1
|
* Changed name from entry to thread_entry to be more compatible withJoel Sherrill1997-07-092-2/+2
| | | | Ada interface where entry is a keyword.
* headers updated to reflect new style copyright notice as partJoel Sherrill1997-04-2221-105/+105
| | | | of switching to the modified GNU GPL.
* Reduced number of POSIX thread priorities from 255 to 254 to avoid conflictsJoel Sherrill1997-04-152-4/+10
| | | | | of lowest priority with the RTEMS IDLE thread. This was causing the lowest priority GNAT Ada task to never run.
* created. Split getpid() from types.c to allow it to be overridden byJoel Sherrill1997-03-101-0/+22
| | | | | cxe1001 of the ACVC 2.0.1. This allows gnat/rtems to pass the partition tests.
* Fixed bug where the initial detachstate was not being set properlyJoel Sherrill1997-03-101-1/+1
|
* Modified calls to _Thread_Change_priority to take a third argument. The newJoel Sherrill1997-03-081-3/+7
| | | | | | | | | 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.
* Removed getpid from this file and made it its own file. This lets itJoel Sherrill1997-03-081-10/+0
| | | | get replaced as required.
* Added commit to indicate exepcted _Thread_Dispatch_disable_level. HopefullyJoel Sherrill1997-03-081-0/+4
| | | | no one will ever get confused here again and try to enable dispatching. :(
* Switch to using newlib's implementation of time().Joel Sherrill1997-01-281-0/+3
|
* changed stack size of posix initialization threads to double the minimumJoel Sherrill1996-09-301-0/+3
| | | | stack size so more of acvc would pass.
* added routine _POSIX_Timespec_subtractJoel Sherrill1996-09-171-0/+31
|
* Added code to insure that the post switch extension was executed andJoel Sherrill1996-09-171-0/+5
| | | | | | to made signals sent to a particular thread from an ISR operated correctly. This behavior was required by the exception detection/reporting code in the gnat runtime.
* Corrected implementation of timed wait on condition variables. FirstJoel Sherrill1996-09-171-29/+52
| | | | | | | | the timeout is given as a wall-time not an interval as was previously implemented. Second, the interpretation of ETIMEDOUT behavior was incorrect as all possible error cases needed to be checked before this error was returned. This caused problems when the wall-time specified was in the past.
* added prototype for _POSIX_Timespec_subtractJoel Sherrill1996-09-171-0/+11
|
* moved PTHREAD_MINIMUM_STACK_SIZE from pthread.c to pthread.h so it would beJoel Sherrill1996-09-081-1/+0
| | | | visible to other files.
* Ada task stack size minimize is twice that for regular pthreads.Joel Sherrill1996-09-081-2/+2
|
* moved PTHREAD_MINIMUM_STACK_SIZE from pthread.c to here so it would beJoel Sherrill1996-09-081-0/+2
| | | | visible to other files.
* default thread attributes: default value for inheritsched changed fromJoel Sherrill1996-09-051-5/+25
| | | | | | | | | | | | explicit to inherit scheduler to be consistent with FSU pthreads for gnat. _POSIX_Threads_Create_extension: now inherit signal blocked mask from creator if the new thread is a posix thread. _POSIX_Threads_Initialize_user_threads: make sure posix initialization threads start with a useful priority. If they inherit the priority of the creating thread, they will end up at the same priority as the idle thread. Since the idle thread does not yield, they will not run.
* pthread_mutex_setprioceiling: fixed bug where returned priority wasJoel Sherrill1996-09-051-1/+3
| | | | not converted from core priority to posix priority.
* nanosleep: negative value for tv_sec is no longer an error. It nowJoel Sherrill1996-09-051-4/+10
| | | | is changed into being a 0 delay.
* new file to support GNU Ada.Joel Sherrill1996-08-291-0/+28
| | | | | currently the only routine in this file simply returns the minimum stack size for each thread.
* fixed typo .. changed == to !=Joel Sherrill1996-08-271-1/+1
|
* check that we were passed a valid mutex and ignore errors from theJoel Sherrill1996-08-271-0/+8
| | | | | later pthread_mutex_lock. This makes our behavior more compatible with that of FSU pthreads.

* clock_gettime: changed assert condition to a standard error codeJoel Sherrill1996-08-151-2/+3
| | | | clock_getres: now checking for a null pointer being passed in
* sched_rr_get_interval: converted assert condition into a standard errorJoel Sherrill1996-08-151-1/+5

|
* pthread_kill: moved check for SA_SIGINFO to allow for validation of allMark Johannes1996-08-151-7/+7
