The kernel space parts of standard system header files were protected
against misuse by a preprocessor error directive. This approach does
not work well with tools such as Doxygen. Provide the kernel space
items only if the required defines are present.
The application configuration options are documented in
"cpukit/doxygen/appl-config.h". Since the application configuration
option defines are also present in multiple test program sources, the
"#OPTION" references cannot be mapped to a unique definition. Add an
anchor for each option and reference it to avoid the issues with the
multiple definitions.
Update #3994.
There are different cases for _ISR_lock_ISR_disable() and
_ISR_lock_ISR_enable() in the case RTEMS_SMP is defined or
RTEMS_PROFILING is defined, so remove the related code.

Update #4662.
Correctly calculate the array index and shift value in
_Processor_mask_To_uint32_t(). The bugs had no impact yet since this
function was always called with a zero value for the index in RTEMS.
This enables the tracing of interrupt entry/exit events through an
application configuration option. The interrupt processing can be
viewed with Trace Compass using rtems-record-lttng from the RTEMS Tools.
Update #4769.
This patch changes the license to BSD-2 for all source files where the
copyright is held by Aeroflex Gaisler, Cobham Gaisler, or Gaisler Research.
Some files also includes copyright right statements from OAR and/or
embedded Brains in addition to Gaisler.
Updates #3053.
By default, allocate the IDLE task storage areas from the RTEMS Workspace.
This avoids having to estimate the thread-local storage size in the default
configuration.
Add the application configuration option CONFIGURE_IDLE_TASK_STORAGE_SIZE to
request a static allocation of the task storage area for IDLE tasks.
Update #3835.
Update #4524.
Add the INTERNAL_ERROR_IDLE_THREAD_CREATE_FAILED fatal error in case the
creation of an idle thread fails. This may happen due to a failing create
extension provided by the application.
Place this member placed directly after the end of the common block so that
the structure offsets are as small as possible. This helps on instruction
set architectures with a very limited range for intermediate values. For
example, see the __aeabi_read_tp() implementation for ARM Thumb-1.
Update #3835.
Allow the IDLE stack allocator to change the stack size. This can be
used by applications with a very dynamic thread-local storage size to
adjust the thread storage area of the IDLE tasks dynamically.
Update #4524.
- Add support to get the parent address and size cells
- Provide support to get a reg prop address map
- Change getting a set of properties to uintptr_t
- Improve the debug mode of the ls command to print all props
Closes#4729
All CPU ports used the same _CPU_Counter_difference() implementation. Remove
this CPU port interface and mandate a monotonically increasing CPU counter.
Close#3456.
C99 allows array function parameters to use the static keyword for their
sizes. This tells the compiler that the parameter will have at least the
specified size, and calling code will fail to compile if that guarantee is
not met. However, this syntax is not legal in C++.
This commit reverts r300824, which worked around the problem for
sys/sys/md5.h only, and introduces a new macro: min_size(). min_size(x) can
be used in headers as a static array size, but will still compile in C++
mode.

This implements SHA-512/256, which generates a 256 bit hash by
calculating the SHA-512 then truncating the result. A different initial
value is used, making the result different from the first 256 bits of
the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on
64bit platforms, so the result is a faster 256 bit hash.
The main goal of this implementation is to enable support for this
faster hashing algorithm in ZFS. The feature was introduced into ZFS
in r289422, but is disconnected because SHA-512/256 support was missing.
A further commit will enable it in ZFS.
This is the follow on to r292782

Use the C99 'static' keyword to hint to the compiler IVs and output digest
sizes. The keyword informs the compiler of the minimum valid size for a given
array. Obviously not every pointer can be validated (i.e., the compiler can
produce false negative but not false positive reports).
No functional change. No ABI change.

cperciva's libmd implementation is 5-30% faster
The same was done for SHA256 previously in r263218
cperciva's implementation was lacking SHA-384 which I implemented, validated against OpenSSL and the NIST documentation

Issue an error message if an SMP-specific scheduler is used and
RTEMS_SMP is disabled. This might be a more informative compared to
compiler or linker errors.
