Test the proper serialization of explicit thread priority changes (for
example rtems_task_set_priority()) and thread priority changes carried
out by thread queues (locking protocols such as priority inheritance).
With RTEMS_DEBUG enabled, the new test case fails with an assertion. It
is fixed in a follow up commit.
Update #5159.
In _Terminate(), everything after invoking the fatal extensions is essentially
dead code. Simplify this code block and provide a reasonable safe fall-back
for badly configured applications. Just disable masked interrupts and execute
an idle loop.
Update #5067.
On some targets or configurations, the data cache cannot be disabled.
The data cache may be necessary to provide atomic operations. In SMP
configurations, the data cache may be required to ensure data coherency.
Close#5050.
If the RTEMS_INTERRUPT_LOCK_NEEDS_OBJECT define has a non-zero value,
then the interrupt lock operations require an object of type
rtems_interrupt_lock, otherwise no lock object is required.
This indication can be used to avoid the space overhead for lock objects
when they are not needed. In this case, the lock operations will not
use a lock objects parameter.
Update #4957 and #5038.
This test was broken by b031cf2b19 since
it expects the macros to evaluate to an empty string for non-SMP builds.
This updates the check for the new content.
Add directives to get and set the priority of an interrupt vector.
Implement the directives for the following BSP families:
* arm/lpc24xx
* arm/lpc32xx
* powerpc/mpc55xxevb
* powerpc/qoriq
Implement the directives for the following interrupt controllers:
* GICv2 and GICv3 (arm and aarch64)
* NVIC (arm)
* PLIC (riscv)
Update #5002.
Make the clock driver parameters configurable. Use the maximum counter
frequency to get the best time resolution. Decouple the CPU counter from the
timecounter. Make the tick catch up handling more robust. Add a validation
test for the tick catch up.
The TM27 support may define TM27_INTERRUPT_VECTOR_ALTERNATIVE to provide
an alternative software generated interrupt request which is raised by
_TM27_Raise_alternative() and cleared by _TM27_Clear_alternative().
Both functions shall return an RTEMS status code. This interrupt vector
may be used to test the interrupt controller support on targets which do
not provide generic software generated interrupts.
Update #3716.
For uniprocessor configurations, the selection of
RTEMS_MULTIPROCESSOR_RESOURCE_SHARING results in a priority ceiling
mutex.
Build the MrsP validation tests only if RTEMS_SMP is enabled.
Update #3716.
Measure the runtime of 1000 no-operation instructions. This may help to
investigate runtime measurement variations which do not result from code
generation or source code changes.
The runtime measurement of a function which does nothing and just
returns gives an estimate of the measurement overhead.
Update #3716.
Make some performance tests compatible to other RTEMS versions which do
not allow changing the priority of a task which owns a priority
inheritance mutex.
Update #3716.
