Sebastian Huber b5a21bf139 posix: Avoid Giant lock in sem_getvalue() 
Update #2555.
 2016-04-22 09:25:08 +02:00
Sebastian Huber cca2d8abc4 score: Rename _CORE_RWLock_Obtain() 
Rename _CORE_RWLock_Obtain_for_reading() into
_CORE_RWLock_Seize_for_reading().  Rename
_CORE_RWLock_Obtain_for_writing() into _CORE_RWLock_Seize_for_writing().
Rename _CORE_RWLock_Release() into _CORE_RWLock_Surrender().  This
avoids confusion with the ISR lock acquire and release.

Sebastian Huber 3d0c400558 score: Rename _CORE_barrier_Wait() 
Rename _CORE_barrier_Wait() into _CORE_barrier_Seize().  Rename
_CORE_barrier_Release() into _CORE_barrier_Surrender().  This avoids
confusion with the ISR lock acquire and release.

Sebastian Huber 242a05a586 score: Rename _MRSP_Obtain() 
Rename _MRSP_Obtain() into _MRSP_Seize().  Rename _MRSP_Release() into

release.

Sebastian Huber 88575577fa score: Optimize _Objects_Get_local() 
Make the id the first parameter since usual callers get the object
identifier as the first parameter themself.

Joel Sherrill 8228548d12 Add pthread_getconcurrency() and pthread_setconcurrency() 
This is the very simple implementation specified by the Open Group
for implementations with 1:1 kernel thread to user thread mappings.

http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_getconcurrency.html

updates #2680.
 2016-04-14 16:28:10 -05:00
Sebastian Huber 6efa349850 posix: Run key destructors during thread restart 
POSIX key destructors must be called during thread restart.  Just like
the POSIX cleanup handlers.  This ensures that the TLS object
destructors are called during thread restart for example.  It is
important for the global construction, which uses a thread restart to
run the Init task in a clean environment.

Close #2689.

Sebastian Huber a12724f934 bsp/qoriq: Fix MMU initialization for e6500 
In case a hypervisor mode is present, then we must set MAS8 for some TLB
operations, otherwise the run-time behaviour is unpredictable.

Sebastian Huber 3c293cc795 posix: Rename killinfo()

killinfo() to _POSIX_signals_Send() to cleary mark it as an internal
function.
