Closes #4302.

When the cadence I2C code was moved to a shared directory, the
references were updated but the install locations weren't. This updates
the install locations to match what out-of-tree applications expect.

The BSPs provide memory for the separate C Program Heap initialization
via _Memory_Get(). Most BSPs provide exactly one memory area. Only two
BSPs provide more than one memory area (arm/altera-cyclone-v and
bsps/powerpc/mpc55xxevb). Only if more than one memory area is
provided, there is a need to use _Heap_Extend(). Provide two
implementations to initialize the separate C Program Heap and let the
BSP select one of the implementations based on the number of provided
memory areas. This gets rid of a dependency on _Heap_Extend(). It
also avoids dead code sections for most BSPs.
Change licence to BSD-2-Clause according to file history.
Update #3053.

The BSPs provide memory for the workspace initialization via

Move _Thread_queue_Extract() since this function is not used by the core
services (threads, semaphores, mutexes, message queues).

Remove _Thread_queue_Extract_with_proxy() and move the proxy extraction
to _Thread_MP_Extract_proxy(). Move similar code blocks of the previous
caller of _Thread_queue_Extract_with_proxy() to helper functions.

This patch fixes the following broken behaviour:
While a thread is scheduled on a helping scheduler, while it does not
own a MrsP semaphore, if it obtains a MrsP semaphore, then no
scheduler node using an idle thread and the ceiling priority of the
semaphore is unblocked for the home scheduler.
This could lead to priority inversion issues and is not in line
with the MrsP protocol.
Introduce two new scheduler operations which are only enabled if
RTEMS_SMP is defined. The operations are used to make the scheduler
node of the home scheduler sticky and to clean the sticky property.
This helps to keep the sticky handing out of the frequently used
priority update operation.
Close #4532.

These functions are a faster alternative to _RBTree_Insert_inline() if
it is known that the new node is the maximum/minimum node.

This patch set replaces the CPU budget algorithm enumeration with a set of CPU
budget operations which implement a particular CPU budget algorithm. This
helps to hide the CPU budget algorithm implementation details from the general
thread handling. The CPU budget callouts are turned into CPU budget
operations. This slightly reduces the size of the thread control block.
All schedulers used the default scheduler tick implementation. The tick
scheduler operation is removed and the CPU budget operations are directly used
in _Watchdog_Tick() if the executing thread uses a CPU budget algorithm. This
is performance improvement for all threads which do not use a CPU budget
algorithm (default behaviour).

This adds support for libdebugger under AArch64 using software
breakpoints and the single-step execution mode present in all AArch64
CPUs.
|
|
|
|
|
|
| |
This moves the AArch64 MMU memory type definitions into cpukit for use
by libdebugger since remapping of memory is required to insert software
breakpoints.

Add a test to verify that mapping of machine exceptions to POSIX signals
operates properly when the application requests it.
|
|
|
|
|
|
| |
This adds a confdef option allowing an application to request mapping
machine exceptions to POSIX signals. This is required for some languages
such as Ada.
|
|
|
|
|
| |
Add a test to verify that intercepted exceptions can be resolved and
execution can be resumed.
|
|
|
|
|
| |
This adds the function implementations necessary to add exception
extensions support to AArch64.
|
|
|
|
|
|
|
|
| |
This adds the set of functions necessary to allow more generic handling
of machine exceptions. This initial patch offers the ability to
manipulate a CPU_Exception_frame and resume execution using that
exception information with or without thread dispatch. These functions
are gated behind the RTEMS_EXCEPTION_EXTENSIONS configuration option.

The rate monotonic period statistics were affected by
rtems_cpu_usage_reset(). The logic to detect and work around a CPU
usage reset was broken.
The Thread_Contol::cpu_time_used is changed to contain the processor
time used throughout the entire lifetime of the thread. The new member
Thread_Contol::cpu_time_used_at_last_reset is added to contain the
processor time used at the time of the last reset through
rtems_cpu_usage_reset(). This decouples the resets of the CPU usage and
the rate monotonic period statistics.

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.

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.

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.

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.
|
|
|
|

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.

Added I2C drivers for ZynqMP and updated build system accordingly.
|
|
|
|
|
| |
Certain files related to the Zynq BSP's I2C driver are useable by the ZynqMP BSP as well.
Moved these files to shared directory in anticipation of I2C support for ZynqMP.

Move the TOD validation to the callers of _TOD_Set(). This avoids dead code in
case only rtems_clock_set() is used in an application because rtems_clock_set()
always calls _TOD_Set() with a valid time of day.

Use _Watchdog_Ticks_per_second instead.

The _Thread_Dispatch() function was customized over time and now the
work is done by _Thread_Do_dispatch() and specialized wrappers. The
plain _Thread_Dispatch() is now only used in some CPU ports. Move it to
a separate file to avoid dead code in the general.
