The RTEMS print user need to know nothing about a particular printer
implementation. In particular get rid of the <stdio.h> include which
would be visible via <rtems.h>.
|
|
|
|
|
| |
Rename RTEMS_PRINTF_ATTRIBUTE() into RTEMS_PRINTFLIKE() (similar to
<sys/cdefs.h> __printflike()) and move it to <rtems/score/basedefs.h>.

%asr22 and %asr23.

Use priority maximum of scheduler instance. This avoids a potential

In case the CPU architecture provides no specialized
_CPU_Bitfield_Find_first_bit() macro, then use the __builtin_clz()
builtin in case __GNUC__ is defined.
|
|
|
|
| |
Turn _Bitfield_Find_first_bit() macro into an inline function.

The priority bit map can deal with a maximum of 256 priority values
ranging from 0 to 255. Consistently use an unsigned int for
computation, due to the usual integer promotion rules.
Make Priority_bit_map_Word definition architecture-independent and
define it to uint16_t. This was already the case for all architectures
except PowerPC. Adjust the PowerPC bitmap support accordingly.

Rename __log2table into _Bitfield_Leading_zeros since it acually returns
the count of leading zeros of an 8-bit integer. The value for zero is a
bit odd. Provide it unconditionally.

The Classic binary semaphores without a locking protocol
(RTEMS_BINARY_SEMAPHORE) could be released by everyone, e.g. in contrast
to the POSIX mutexes (all variants) or the Classic binary semphores with
priority inheritance or ceiling, there was no owner check in the release
path.
This behaviour was a bit unexpected and not documented. Add an owner
check to the release path. Update sptests/sp42 accordingly.
This change has nothing to do with the simple binary semaphores
(RTEMS_SIMPLE_BINARY_SEMAPHORE) which have no owner at all.

The approach with the generation number was broken. The load/store of
the current lock, the thread queue and the thread queue operations were not
properly synchronized. Under certain conditions on a PowerPC T4240 old
thread queue operations operated on a new thread queue (NULL pointer).

A read-modify-write operation is necessary to read the last value
written.
See for example C11 standard or Power ISA 2.07, Book II: Power ISA
Virtual Environment Architecture, Section 1.6.3 Memory Coherence
Required [Category: Memory Coherence] and Section 1.7.3 Atomic Update.

Provide dedicated seize and surrender methods for inherit priority
mutexes. This eliminates CORE_mutex_Attributes.
|
|
|
|
|
| |
Rework seize and surrender methods to use CORE_ceiling_mutex_Control.
This eliminates CORE_mutex_Disciplines.
|
|
|
|
|
|
|
|
| |
Add CORE_recursive_mutex_Control and CORE_ceiling_mutex_Control to avoid
the run-time evaluation of attributes to figure out how a particular
mutex methods should behave. Start with the no protocol variants. This
eliminates the CORE_MUTEX_DISCIPLINES_FIFO and
CORE_MUTEX_DISCIPLINES_PRIORITY disciplines.

Due to the unified status codes, we can now use a common flush and
destroy method for semaphore and mutex variants.
|
|
|
|
|
| |
Remove superfluous support for simple binary semaphores. With this we
can get rid of the CORE_MUTEX_NESTING_BLOCKS variant.
|

Replace the ISR lock in MRSP_Control with a thread queue. This
simplifies the Classic semaphore implementation. Only the lock part of
the thread queue is used.

Move the safety check performed by
_CORE_mutex_Check_dispatch_for_seize() out of the performance critical
path and generalize it. Blocking on a thread queue with an unexpected
thread dispatch disabled level is illegal in all system states.
Add the expected thread dispatch disable level (which may be 1 or 2
depending on the operation) to Thread_queue_Context and use it in
_Thread_queue_Enqueue_critical().
|
|
|
|
|
|
| |
Add _Thread_queue_Context_set_MP_callout() to simplify
_Thread_queue_Context_initialize(). This makes it possible to more
easily add additional fields to Thread_queue_Context.
|
|
|
|
|
|
| |
Adjust thread queue layout according to Newlib. This makes it possible
to use the same implementation for <sys/lock.h> and CORE mutexes in the
future.

Unify the status codes of the Classic and POSIX API to use the new enum
Status_Control. This eliminates the Thread_Control::Wait::timeout_code
field and the timeout parameter of _Thread_queue_Enqueue_critical() and
_MPCI_Send_request_packet(). It gets rid of the status code translation
tables and instead uses simple bit operations to get the status for a
particular API. This enables translation of status code constants at
compile time. Add _Thread_Wait_get_status() to avoid direct access of
thread internal data structures.

Drop the multiprocessing (MP) dependent callout parameter from the
thread queue extract, dequeue, flush and unblock methods. Merge this
parameter with the lock context into new structure Thread_queue_Context.
This helps to gets rid of the conditionally compiled method call
helpers.
|
|
|
|
|
| |
Get rid of the mp_id parameter used for some thread queue methods. Use
THREAD_QUEUE_QUEUE_TO_OBJECT() instead.
|
| |
|
|
|
|
|
|
|
| |
We must call the MP callout for proxies if we unblock them after a
thread queue extraction. This was missing in
_Thread_queue_Flush_critical(). Move thread remove timer and unblock
code to new function _Thread_Remove_timer_and_unblock().

This change adds rtems_printf and related functions and wraps the
RTEMS print plugin support into a user API. All references to the
plugin are removed and replaced with the rtems_printer interface.
Printk and related functions are made to return a valid number of
characters formatted and output.
The function attribute to check printf functions has been added
to rtems_printf and printk. No changes to remove warrnings are part
of this patch set.
The testsuite has been moved over to the rtems_printer. The testsuite
has a mix of rtems_printer access and direct print control via the
tmacros.h header file. The support for begink/endk has been removed
as it served no purpose and only confused the code base. The testsuite
has not been refactored to use rtems_printf. This is future work.

Uniformly use *_Get() to get an object by identifier with a lock
context.
|
|
|
|
|
|
| |
Rename _Objects_Get_local() into _Objects_Get(). Confusions with the
previous _Objects_Get() function are avoided since the Objects_Locations
parameter is gone.

Delete now unused Objects_Locations.
