This field is unused except for special case simulator clock drivers.
In these places use an alternative. Add and use
_Thread_Set_global_exit_status() and _Thread_Get_global_exit_status().
Call _SMP_Handler_initialize() later and move bsp_smp_initialize() into
_SMP_Handler_initialize(). Change bsp_smp_initialize() prototype to
match integer types of calling context.
Delete rtems_configuration_get_smp_maximum_processors(). Delete
rtems_configuration_smp_maximum_processors variable. Add
maximum_processors field to rtems_configuration_table if RTEMS_SMP is
defined. Add rtems_configuration_get_maximum_processors().
Add and use rtems_libio_exit_helper. Add rtems_libio_exit().
The fclose(stdin) etc. makes no sense during exit. This would use the
_REENT structure of the thread calling _exit().
Only one of the following can be defined.
+ CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
+ CONFIGURE_APPLICATION_DOES_NOT_NEED_CLOCK_DRIVER
+ CONFIGURE_APPLICATION_NEEDS_TIMER_DRIVER
Otherwise it is a configuration error which can be detected at
compilation time.
The output of the modules.html is much improved. Most
filesystem and POSIX API related groups are properly nested.
Some formatting issues were addressed as were multiple
inconsistencies.
Do not return from rtems_initialize_start_multitasking() and call
rtems_fatal() instead with a fatal source of RTEMS_FATAL_SOURCE_EXIT and
a fatal code with the exit status.
Remove all bsp_cleanup() functions. The boot_card() is now a no return
function.
Add CPU port type CPU_Exception_frame and function
_CPU_Exception_frame_print().
The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh,
sparc64, and v850 use an empty default implementation of
_CPU_Exception_frame_print().
Add rtems_exception_frame and rtems_exception_frame_print().
Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal()
with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc,
and sparc for unexpected exceptions.
Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the
BSP_PRINT_EXCEPTION_CONTEXT define used in the default
bsp_fatal_extension().
Add test sptests/spfatal26.
The initial extensions remain now in a read-only table and will not be
copied to work space memory. The extension chains are statically
initialized. This makes it possible to call _User_extensions_Iterate()
independent of the system state. It is now guaranteed that the fatal
callout of the initial extensions will be called provided the stack
pointer, the read-only data, and code memory are valid.
The comment in confdefs.h shows how to do it:
An application can define its own scheduling policy by defining
CONFIGURE_SCHEDULER_USER and the following:
- CONFIGURE_SCHEDULER_ENTRY_POINTS
- CONFIGURE_MEMORY_FOR_SCHEDULER - base memory
- CONFIGURE_MEMORY_PER_TASK_FOR_SCHEDULER - per task memory
