Move the CORE_message_queue_Buffer definition to a separate header file to be
able to use it independent of the remaining Message Queue Handler API.
Change license to BSD-2-Clause according to file history.
Update #3053.
Update #4007.
Simplify object name to identifier directives. Using
_RTEMS_Name_to_id() to implement the directives enables a tail call
optimization.
Change license to BSD-2-Clause according to file history.
Update #3053.
Rename this header file to later move <t.h> to <rtems/test.h>. The main
feature provided by <rtems/test-info.h> is the output of standard test
information which is consumed by the RTEMS Tester.
Update #3199.
Add a simplified path evaluation function IMFS_eval_path_devfs() for a
device only IMFS configuration.
The code size can be further reduced by the application if it disables
the support for legacy IO drivers via:
#define CONFIGURE_IMFS_DISABLE_MKNOD
#define CONFIGURE_IMFS_DISABLE_MKNOD_DEVICE
Obsolete CONFIGURE_MAXIMUM_DEVICES. Remove BSP_MAXIMUM_DEVICES.
Update #3894.
Update #3898.
Remove all comments and copyrightable content from the moved content.
Use BSD-2-Clause license for new file.
Change licence of <rtems/confdefs.h> to BSD-2-Clause according to file
history.
Update #3053.
Close#3875.
Remove all comments and copyrightable content from the moved content.
Use BSD-2-Clause license for new file.
Move the default configuration to library files so that application
configurations do not include the definitions for the default case.
Update #3053.
Update #3875.
Remove comments and copyrightable content from the moved content. Use
BSD-2-Clause for new file according to file history of
<rtems/confdefs.h>.
Update #3053.
Update #3875.
Unify handling of obsolete configuration options. Remove comments and
copyrightable content from the moved content. Use BSD-2-Clause license
for new file.
Update #3053.
Update #3875.
Move the idle thread stack size configuration constant out of the
configuration table.
Add THREAD_IDLE_STACK_SIZE_DEFAULT and use it to provide a default
definition of the idle thread stack size constant.
Update #3875.
The CONFIGURE_HAS_OWN_INIT_TASK_TABLE and
CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE are the last *_HAS_OWN_*
configuration options. These two options are probably unused, see also:
* https://lists.rtems.org/pipermail/users/2019-April/033129.html
* https://lists.rtems.org/pipermail/users/2019-April/033130.html
Removing them simplifies the configuration. If there is a real user need
which shows up after the removal, we can resurrect them on demand.
Using CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE would have required the
use of the undocumented CONFIGURE_POSIX_INIT_THREAD_TABLE_NAME and
CONFIGURE_POSIX_INIT_THREAD_TABLE_SIZE configuration options.
Update #3874.
Add rtems_scheduler_get_processor_maximum() as a replacement for
rtems_get_processor_count(). The rtems_get_processor_count() is a bit
orphaned. Adopt it by the Scheduler Manager. The count is also
misleading, since the processor set may have gaps and the actual count
of online processors may be less than the value returned by
rtems_get_processor_count().
Update #3732.
Add low level event recording infrastructure for system and user
defined events. The infrastructure is able to record high frequency
events such as
* SMP lock acquire/release,
* interrupt entry/exit,
* thread switches,
* UMA zone allocate/free, and
* Ethernet packet input/output, etc.
It allows post-mortem analysis in fatal error handlers, e.g. the last
events are in the record buffer, the newest event overwrites the oldest
event. It is possible to detect record buffer overflows for consumers
that expect a continuous stream of events, e.g. to display the system
state in real-time.
The implementation supports high-end SMP machines (more than 1GHz
processor frequency, more than four processors).
Add a new API instead. The implementation uses per-processor data
structures and no atomic read-modify-write operations. It is uses
per-processor ring buffers to record the events.
The CPU counter is used to get the time of events. It is combined with
periodic uptime events to synchronize it with CLOCK_REALTIME.
The existing capture engine tries to solve this problem also, but its
performance is not good enough for high-end production systems. The
main issues are the variable-size buffers and the use of SMP locks for
synchronization. To fix this, the API would change significantly.
Update #3665.
The sbintime_t is a non-POSIX type and not visible if strict standard
options are selected.
Move implementation details from <rtems/score/timestamp.h> to
<rtems/score/timestampimpl.h>.
Update #3598.
