Do not save and restore the thread wait information. This is
superfluous and may overwrite thread wait information updates due to
interrupts leading to system corruption.
|

Remove the Thread_queue_Queue::operations field to reduce the size of
this structure. Add a thread queue operations parameter to the
_Thread_queue_First(), _Thread_queue_First_locked(),
_Thread_queue_Enqueue(), _Thread_queue_Dequeue() and
_Thread_queue_Flush() functions. This is a preparation patch to reduce
the size of several synchronization objects.

Update #2408.

Store the unblock signals to exploit the zero-initialization of the
thread control block.
|
| |
|
|
|
|
|
|
| |
Rename _POSIX_Absolute_timeout_to_ticks() to
_TOD_Absolute_timeout_to_ticks() and move it to the score directory.
Delete empty <rtems/posix/time.h>.
|
|
|
|
|
| |
Use a parameter for _Thread_queue_Enqueue() instead to reduce memory
usage.
|
|
|
|
|
|
|
|
|
|
|
| |
Move the complete thread queue enqueue procedure into
_Thread_queue_Enqueue_critical(). It is possible to use the thread
queue lock to protect state of the object embedding the thread queue.
This enables per object fine grained locking in the future.
Delete _Thread_queue_Enter_critical_section().
Update #2273.

usage.

Add a local context structure to the SMP lock API for acquire and
release pairs. This context can be used to store the ISR level and
profiling information. It may be later used to enable more
sophisticated lock algorithms, e.g. MCS locks.
There is only one lock that cannot be used with a local context. This
is the per-CPU lock since here we would have to transfer the local
context through a context switch which is very complicated.
|
|
|
|
|
|
| |
Add and use _POSIX_signals_Release(). The post-switch handler is not
protected by disabled thread dispatching. Use proper SMP lock for
signal management.

Move implementation specific parts of tqdata.h, threadq.h and
threadq.inl into new header file threadqimpl.h. The threadq.h contains
now only the application visible API.
Delete tqdata.h.

Move implementation specific parts of states.h and states.inl into new

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

PR 1855/cpukit
* posix/src/psignal.c, posix/src/pthread.c, posix/src/pthreadjoin.c:
Correct signal processing during pthread_join. We are supposed to
unblock the thread waiting on a pthread_join(), dispatch the signal
handler, account for it potentially overwriting errno, and then have
the thread return to blocking within pthread_join().
