The priority inheritance and ceiling CORE mutexes wrongly used the FIFO
queueing discipline. Delete misleading _CORE_mutex_Is_priority(). Bug
introduced by 1e1a91ed11.
Add test sptests/spmutex01, since no existing uni-processor test covered
the thread priority queueing discipline for CORE mutexes.
Fix the interrupt and stop the spurious interrupt from happening.
The fix moves the EOI to C code and cleans that functionality out
of the asm part of the ISR handler.
The code checks the ISR and IRR registers on the enable.
Only ack the master for a slave IRQ if the slave has no other pending
requests.
Move the gdb stub from the i386 UART code to use the libchip drivers.
Use any ports discovered during the probes.
Add gdb control to the boot command line.
Change the device naming to the full device path, not a partial path.
For example /dev/com1.
GCC 6.0 previews give the following warning on sonic.c:
../../../../../rtems/c/src/libchip/network/sonic.c:837:11: warning:
statement is indented as if it were guarded by... [-Wmisleading-indentation]
This was discussed here:
https://lists.rtems.org/pipermail/devel/2016-March/014004.html
and we concluded it would be better to rewrite the entire snippet.
Account for the terminating null character. Use _POSIX_PATH_MAX instead
of NAME_MAX according to _POSIX_Semaphore_Manager_initialization() and
_POSIX_Message_queue_Manager_initialization().
Rename _TOD_Set() into _TOD_Set_with_timespec(). Rename
_TOD_Set_with_timestamp() into _TOD_Set(). This is now in line with
_TOD_Get() and _TOD_Get_as_timespec(). The timestamp is the canonical
format.
The mq_open() function returns a descriptor to a POSIX message queue
object identified by a name. This is similar to sem_open(). In
contrast to the POSIX semaphore the POSIX message queues use a separate
object for the descriptor. This extra object is superfluous, since the
object identifier can be used directly for this purpose, just like for
the semaphores.
Update #2702.
Update #2555.
Move message notification to end of critical section and delegate the
message queue release to the notification handler. It may do more
complex notification actions out of the critical section.
Update #2555.
