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().

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.

Rename _Internal_error_Occurred() into _Terminate().
|
|
|
|
|
|
| |
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.
|
|
|
|
|
|
| |
Merge RTEMS_FATAL_SOURCE_BSP_GENERIC and RTEMS_FATAL_SOURCE_BSP_SPECIFIC
into new fatal source RTEMS_FATAL_SOURCE_BSP. This makes it easier to
figure out the code position given a fatal source and code.
|

This error case is no longer required since rtems_shutdown_executive()
can be called anytime, anywhere
|
|
|
|
|
|
| |
Move _SMP_Request_other_cores_to_shutdown() invocation from
rtems_shutdown_executive() to _Internal_error_Occurred() to allow a
proper shutdown on SMP configurations even in the error case.
|
|
|
|
|
|
|
| |
Disable interrupts as the first step in _Internal_error_Occurred() to
get a defined execution context for the fatal extensions.
Make _ISR_Disable_without_giant() available for non-SMP configurations.
|
|
|
|
|
|
| |
Merge systems states SYSTEM_STATE_SHUTDOWN and SYSTEM_STATE_FAILED into
new system state SYSTEM_STATE_TERMINATED. This reflects that all system
termination paths end up in _Internal_error_Occurred().
|
|
|
|
| |
Add bsp_generic_fatal().

This patch is a task from GCI 2012 which improves the Doxygen
comments in the RTEMS source.

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.

Call the fatal handlers of the user extensions before the update of
_Internal_errors_What_happened. This reduces the requirements on the
execution context further. Now a valid read-write data is only required
after the call to the fatal handlers.

This reverts commit 7d0bdcac1ac20d6f22b24689c16e6aa7bc3c1e40.

Add ppc_exc_print_frame_and_context() which prints an exception frame
and the context via printk().
The global exception handler will call now rtems_fatal() with source
RTEMS_FATAL_SOURCE_POWERPC_EXCEPTION. The fatal code will contain the
pointer value to the exception frame.

Include <bsp/default-initial-extension.h> in all BSPs. Call
rtems_fatal() with RTEMS_FATAL_SOURCE_EXIT as source and the exit()
status code as fatal code in every bsp_cleanup(). Move previous
bsp_cleanup() code into bsp_fatal_extension().
|
| |
|
|
|
|
|
|
| |
Add rtems_bdbuf_fatal_code as a replacement for the previous fatal error
codes. Remove unused error codes. Add new error codes. Use
rtems_fatal() with RTEMS_FATAL_SOURCE_BDBUF as source.

This enum value ensures that the enum type needs at least 32-bits for
architectures with short enums.
|

|

Use INTERNAL_ERROR_CPU_ISR_INSTALL_VECTOR on PowerPC for
_CPU_ISR_install_vector().
|
|
|
|
|
| |
Add Internal_errors_Information::nest_level. This helps to detect
recursive calls to _Internal_error_Occurred().
|
| |
|
|
|
|
|
| |
Define _System_state_Current and _Internal_errors_What_happened in
interr.c to make _Internal_error_Occurred() more independent.

The work areas (RTEMS work space and C program heap) will be initialized
now in a separate step and are no longer part of
rtems_initialize_data_structures(). Initialization is performed with
tables of Heap_Area entries. This allows usage of scattered memory
areas present on various small scale micro-controllers.
The sbrk() support API changes also. The bsp_sbrk_init() must now deal
with a minimum size for the first memory chunk to take the configured
work space size into account.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
