Add this application configuration option. This configuration option can be
used to reserve space for the dynamic linking of modules with thread-local
storage objects.
Add RTEMS_TASK_STORAGE_ALIGNMENT to define the minium alignment of a
thread-local storage size.
Update #4074.

Use the following variant which was already used by most source files:
#ifdef HAVE_CONFIG_H
#include "config.h"
#endif

Update #3806.

Allocate the per-CPU data for secondary processors directly from the
heap areas before heap initialization and not via
_Workspace_Allocate_aligned(). This avoids dependency on the workspace
allocator. It fixes also a problem on some platforms (e.g. QorIQ) where
at this early point in the system initialization the top of the RAM is
used by low-level startup code on secondary processors (boot pages).
Update #3507.

|
An invalid heap usage such as a double free is usually a fatal error
since this indicates a use after free. Replace the use of printk() in
free() with a fatal error.
Update #3437.
|
|
Add RTEMS_FATAL_SOURCE_PANIC to rtems_fatal_source_text().
Update #3244.
|
|
Add a default implementation of _arc4random_getentropy_fail with an
internal error.
Update #3239.

The TEST_EXTERN is a used only by the system.h style tests and they use
CONFIGURE_INIT appropriately.
Update #3170.

- Remove the printf support leaving the direct printk support configured
with TESTS_USE_PRINTK and all other output goes via a buffered vsniprintf
call to printk.
- Control the test's single init for functions and global data with
TEST_INIT and not CONFIGURE_INIT. They are now separate.
Updates #3170.

Add new fatal error INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT.

On SMP configurations, it is a fatal error to call blocking operating
system with interrupts disabled, since this prevents delivery of
inter-processor interrupts. This could lead to executing threads which
are not allowed to execute resulting in undefined behaviour.
The ARM Cortex-M port has a similar problem, since the interrupt state
is not a part of the thread context.
Update #2811.

This function is useful for operations which synchronously block, e.g.
self restart, self deletion, yield, sleep. It helps to detect if these
operations are called in the wrong context. Since the thread dispatch
necessary indicator is not used, this is more robust in some SMP
situations.
Update #2751.

The mutex objects use the owner field of the thread queues for the mutex
owner. Use this and add a deadlock detection to
_Thread_queue_Enqueue_critical() for thread queues with an owner.
Update #2412.
Update #2556.
Close #2765.

This simplifies the global construction.
Update #2514.

This define was superfluous, undocumented and used inconsistently.

Issue a fatal error in case a thread is deleted which still owns
resources (e.g. a binary semaphore with priority inheritance or ceiling
protocol). The resource count must be checked quite late since RTEMS
task variable destructors, POSIX key destructors, POSIX cleanup handler,
the Newlib thread termination extension or other thread termination
extensions may release resources. In this context it would be quite
difficult to return an error status to the caller.
An alternative would be to place threads with a non-zero resource count
not on the zombie chain. Thus we have a resource leak instead of a
fatal error. The terminator thread can see this error if we return an
RTEMS_RESOURCE_IN_USE status for the rtems_task_delete() for example.

Use rtems_fatal() instead of _CPU_Fatal_halt() to shutdown processors in
SMP configurations since this allows intervention of BSP or application
specific fatal extensions.
|
|
Rename rtems_internal_error_description() to
rtems_internal_error_text(). Rename rtems_fatal_source_description() to
rtems_fatal_source_text(). Rename rtems_status_code_description() to
rtems_status_text(). Remove previous implementation of
rtems_status_text().

Use INTERNAL_ERROR_CPU_ISR_INSTALL_VECTOR on PowerPC for
_CPU_ISR_install_vector().
