Remove the unused _SMP_Send_message_multicast() and
_SMP_Send_message_broadcast().
|
|
The per-CPU states which control the SMP system initialization were added quite
early during the SMP support development. Replace this initial implementation
with a simplified one. There is no longer a global SMP lock required which
serialized the state changes of all processors. The new implementation better
integrates with the per-CPU jobs.
|
|
Remove _CPU_SMP_Processor_event_broadcast() and
_CPU_SMP_Processor_event_receive(). These functions are hard to use since they
are subject to the lost wake up problem.
|
|
Use the same function to output the '\r\n' combination produced by
rtems_putc(). Fix the format.
Change licence according to file history.
Update #3053.
|
|
Use the same function pointer value to check against NULL and call the
function (if non-NULL).
Fix format, add Doxygen comments, and reduce includes.

Users have access to the fatal error source and code though the fatal error
extension. The user-specific fatal error handling should be done in statically
initialized fatal error handlers. The _Internal_errors_What_happened was
updated after the fatal error extension. In addition, there was no API to get
the information stored in _Internal_errors_What_happened. In SMP
configurations, this object could contain a mix of different fatal errors.
Remove this object to save some bytes of storage.
|
|
Add RTEMS_INTERRUPT_ENTRY_INITIALIZER(),
rtems_interrupt_entry_initialize(), and
rtems_interrupt_entry_remove(). This allows to install interrupt
handlers using user-provided storage as an alternative to
rtems_interrupt_handler_install() which has to allocate memory.
Update #3269.
|
|
Add RTEMS_FATAL_SOURCE_SPURIOUS_INTERRUPT as the fatal source for
spurious interrupts. Use the interrupt vector number of the spurious
interrupt for the fatal code.

|
|
Add a directive to query the attributes of an interrupt vector. This
can be used for generic tests and system diagnostics.
Update #3269.
|
|
Use <rtems/score/chain.h> which just provides the data types and avoid a
dependency on <rtems/chain.h> which contains the full chain
implementation.

Add rtems_interrupt_raise_on(). Document the currently not implemented
rtems_interrupt_clear(). Remove the not implemented and badly named
rtems_interrupt_cause() directive.
Update #3269.
|
|
|
|
Prefer RTEMS_FATAL_SOURCE_EXCEPTION over
INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT since the fatal code
(rtems_exception_frame) provides more context.

Close #4463.

The Cortex-R52 does not support cache coherency and the shareable memory
attribute. If a region is configured to be shareable, then it falls
back to use non-cacheable memory.

This change allows for the migration of higher priority tasks on the
arrival of a lower priority task limited by affinity constraints.

Move _ISR_Handler() to a separate file since it is now only used if a handler
is installed by _CPU_ISR_install_raw_handler().
Statically initialize the traps for external interrupts to use the new
_SPARC_Interrupt_trap() which directly dispatches the interrupt handlers
installed by rtems_interrupt_handler_install() via the BSP-provided
_SPARC_Interrupt_dispatch().
Since the trap table is now fully statically initialized, there is no longer a
dependency on the Cache Manager in the default configuration.
Update #4458.
|
|
This makes them usable in multiple files.
Update #4458.
|
|
Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap()
for all unexpected traps. This enables a proper RTEMS fatal error handling
right from the start. Do not rely on the stack and register settings which
caused an unexpected trap. Use the ISR stack of the processor to do the fatal
error handling. Save the full context which caused the trap. Fatal error
handler may use it for error logging.
Unify the _CPU_Exception_frame_print() implementations and move it to cpukit.
Update #4459.
|
|
Move _CPU_ISR_install_raw_handler() and _CPU_ISR_install_vector() to separate
files. The goal is to make their use optional.
Update #4458.
Update #4459.
|
|
The _ISR_Handler_initialization() does not touch the _ISR_Vector_table[]. Move
the definition of _ISR_Vector_table[] to a separate file.
Change license to BSD-2-Clause according to file history and re-licensing
agreement.
Update #3053.
|
|
This variable is actually contained in _Per_CPU_Information[] which is already
zero initialized.
Remove superfluous includes.
|
|
This CPU port macro was not used. Since the _ISR_Vector_table[] is statically
allocated, CPU ports could initialize this table in _CPU_Initialize() if
necessary. Remove _CPU_Initialize_vectors() to simplify the CPU port
interface.

This adds the possibility to open an I2C bus with O_NONBLOCK (or set it
later via fcntl) to get non-blocking transmissions. This means that if
the bus is busy, a read, write or transfer ioctl will return with a
EAGAIN errno.

The write to RBAR didn't have the valid flag set. Therefore the write to
RASR had an influence on the previously set region. That means for
example that if Region 0 had been enabled but 1 should be disabled due
to a size of 0, the previous code would have disabled region 0 instead.
This patch fixes that behaviour.
Close #4450

|
Don't initialze regions that have a negative size (for example due to a
wrong calculation).

Update #4202.

The change also helps to avoid reports from static analysers since most
callers of _Thread_queue_Make_ready_again() check the unblock status.
|
|
Mention the type of the pointer in the parameter description. Use the
more general term "object" instead of "variable".
Update #3993.
|
|
Make the initialization of the per-CPU data optional.

Set Thread_queue_Context::timeout_absolute in
_Thread_queue_Context_set_timeout_argument() to avoid using it uninitialized.
The bug was introduced by a89ecaa1a94d49ddae7753d6b83923e9d2a00486.

GCC originally needed this 20 years ago. No longer needed, so it
is being removed.
Closes #4391
|
|
A warning was present when building RTEMS that stated that the argument
for malloc() exceeded the maximum object size. To get rid of this, I
changed many places where 'int' was being used to 'size_t'.
