For example, with edge triggered external interrupts we may see spurious
interrupts. Ignore them instead of issuing a fatal error.
Use eieio to synchronize access to the IACK and EOI registers.
Use a loop to immediately services the next pending interrupt without
having to go through the exception epiloge and prologue.
Close#5173.
Some pkg-config variants perform transformations on the --libs options.
This may lead to completely broken linker options. Provide the LDFLAGS
as a variable. Remove "Ldflags:" since this is an unsupported field.
Update #5165.
The RTEMS_CAPTURE_OVERFLOW is an overflow flag for each CPU, and its
value is the same as RTEMS_CAPTURE_INIT. Executing rtems_capture_flush
will set the RTEMS_CAPTURE_INIT flag to 0 in the global flags.
Fixes#5184.
This commit aligns trampolines for THUMB and ARM instructions
(CALL/JUMP24 and THM_JUMP24/THM_PC22).
According to the ARM technical reference in section "Register-relative
and PC-relative expressions":
In Thumb code:
- For B, BL, CBNZ, and CBZ instructions, the value of the PC is the
address of the current instruction plus 4 bytes.
- For all other instructions that use labels, the value of the PC is
the address of the current instruction plus 4 bytes, with bit[1]
of the result cleared to 0 to make it word-aligned.
Closes#5189
When compilation and linking are performed separately, some platforms
(i.e. RISC-V) may require that ABI flags are provided during the linking
step as well as the compilation step.
Closes#5183
The POSIX sporadic server may temporarily remove the real priority of a
thread. Check that the priority node is active before the change is
propagated.
Update #5164.
Previously the system event used by lio_listio was manually added to
event.h and not using rtems-central. This patch corrects that and renames
the event to make it clearer.
Some related dead code has also been removed.

This moves the management console implementation into its own file so
that BSPs which do not need it do not carry the code around with them.
Closes#5120
This adds generic JFFS2 interworking code that allows JFFS2 to be used
on top of any flashdev backend. It currently only supports NOR flashdev
backends.
Commit 3d782180ea changed the reported Git
hash to short. Change this back to the normal Git hash. Existing
support code may rely on this. The short hash is generated based on the
current repository state. The reported hash should be useful also for
future states of the repository. If Git changes the hash algorithm in
the future, then the hash length may be used as an indicator for the
hash algorithm. With a variable hash length this is more difficult.
Simplify expression.
Update #5037.
Accesses to the L2C registers performed by the L2C driver are now
serialized with spin locks. This avoids concurrent access to the L2C
registers by multiple processors. Proposed by GRLIB-TN-0021.
Update #4925.
This updates the implementation of the LEON3 processor power-down
function.
It now contains the workaround for the GR712RC power-down errata
described in GR712RC-UM, version 2.16, section 1.7.8. The workaround is
compatible with other LEON3/LEON4 components.
Update #4875.
Properly serialize 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).
Update #5159.
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.
