The spconfig01 and spmisc01 tests were disabled for all AArch64 BSPs due
to a toolchain issue preventing them from compiling correctly. The
binutils version that contains the fix has been released and integrated
into RSB such that these two tests now build and operate correctly.

This reworks the existing MicroBlaze architecture port and BSP to
achieve basic functionality using the latest RTEMS APIs.

Add a stack allocator hook specifically for allocation of IDLE thread stacks.
This allows the user to decide if IDLE thread stacks are statically allocated
or handled by the same custom allocator mechanism as other thread stacks.
Closes #4524.

Do not use a direct thread dispatch in
_Thread_queue_Surrender_priority_ceiling() since it may be used in condition
variables using POSIX mutexes.

Commit 18c8a270c296addff87f96b8c248f27eba31c24f removed
_Thread_queue_Do_nothing_extract() so we have to check for a non-NULL
queue in all configurations.

Set the postponed jobs count to zero in rtems_rate_monotonic_cancel() so that
rtems_rate_monotonic_get_status() returns a consistent status for inactive
periods.

The schedule operation is only called by rtems_task_mode(). It is
called if preempt mode of the executing thread changes from disabled to
enabled. Since the EDF SMP scheduler does not support the disabled
preemption mode, the schedule operation is never called.

The utimbuf structs in fsimfsconfig01 and fsimfsconfig02 were
being passed to utime uninitialized. This did not cause problems until
utime was changed to use utimensat behind the scenes. Now that
utimensat is called, the values of the utimbuf struct are checked, and
EINVAL is set for invalid values. The utimebuf structs in these tests
could contain invalid values since they are uninitialized.
By zero-initializing the utimbuf structs, we ensure that they pass the
checks in utimensat and that errno is set to the expected ENOTSUP.

All other architectures use uint32_t for interrupt levels and there is
no reason not to do so on AArch64.
|
|
|
|
|
|
|
| |
Context validation for AArch64 was ported from the ARM implementation
without a reinterpretation of the actual requirements. The spcontext01
test just happened to pass because the set of scratch registers in ARM
is a subset of the scratch registers in AArch64.

Replace the boolen return value with the new enum
Thread_queue_Deadlock_status. This improves the code readability.
Improve documentation. Shorten function names.

For uniprocessor configurations, this patch removes dead code in the
_Thread_queue_Surrender() and _Thread_queue_Surrender_priority_ceiling()
functions.
Dead code is removed from _Thread_queue_Surrender_sticky().

This function was unused. It was a relict of the thread queue rework done
during the SMP support development. In an early stage, the extract operation
was called with a NULL thread queue. However, this is no longer the case. The
extract operation is only called if we have a non-NULL thread queue.

Adjust parameter names to match with the declaration. This avoid using
a name reserved by the C standard: "time".

This adds SMP support for AArch64 in cpukit and for the ZynqMP BSPs.
|
|
|
|
|
|
|

ARM's GICv2 is configurable and its attributes vary between
implementations including omission of specific interrupts. This allows
BSPs to accomodate those varying implementations with customized
attribute sets.
|
|
|
|
|
| |
GICv2 can support up to 1024 interrupts, but ZynqMP hardware is only
configured for 192 interrupts.

The order in which step checks for 1 and 2 are not rigidly defined and
may actually occur in either order depending on how the threads execute.
This waits for the job to complete to enforce the existing ordering.

This adds the SMP function that supports spinup of additional CPU cores
using the ARM standard PSCI inteface. This interface is provided by QEMU
as well as ARM Trusted Firmware running in monitor mode (EL3) on ARMv7 and
AArch64 CPUs. This supports activation va SMC or HVC instructions
depending on BSP configuration.

The T_now_tick() is a fall back time measurement using the CPU counter
in case no Clock Driver is configured. Some CPU counter may overflow
during the test execution. Accumulate the elapsed time to reduce the
chance of CPU counter overflows.

If SMP support is enabled and the system has exactly one processor, then
it may use an uniprocessor scheduler. The ask for help, reconsider help
request, and withdraw node operations can be NULL in this case, since
they are only used if a thread has at least one helping scheduler node.
At least two schedulers are required to get a helping node and each
scheduler involved must own at least one processor. This is not
possible on a system with exactly one processor.
|
|
|
|
|
|
|

Issue the new fatal SMP error
SMP_FATAL_SCHEDULER_REQUIRES_EXACTLY_ONE_PROCESSOR if the system starts
with not exactly one processor and an uniprocessor scheduler is
configured.
|

The uniprocessor schedulers do not support systems with more than more
processors. So they rivially support thread pinning and thus the
SMP_FATAL_SCHEDULER_PIN_OR_UNPIN_NOT_SUPPORTED cannot happen.
Add a second default implementation for SMP schedulers which do not
support thread pinning.
Change license to BSD-2-Clause according to file history and re-licensing
agreement.

psxdevctl is supposed to return the value in errno. Before, it was
returning -1 and setting errno. Changed the tests to reflect these
changes. Added code from RRADE's posix_devctl.c.
