Add an RTX hook which gets called when a thread terminates. Add
the function Thread::attach_terminate_hook() to allow users to attach
a hook to this event at runtime.
Add the function osThreadGetInfo to allow various Thread information
to be queried. This includes stack size and maximum stack usage among
other things.
Note - for Cortex-A devices the worst case stack usage is not
available.
Add the functions osThreadsEnumStart, osThreadEnumNext and
osThreadEnumFree to allow enumeration of running threads. Protect
thread creation, thread exit and thread termination with a mutex
so threads are not created or destroyed while an enumeration is
ongoing.
In rtos/rtx/TARGET_CORTEX_M/RTX_CM_lib.h, Image$$ARM_LIB_HEAP$$Base/Image$$ARM_LIB_HEAP$$Length will cause zero memory allocation.
Fix it with Image$$ARM_LIB_HEAP$$ZI$$Base/Image$$ARM_LIB_HEAP$$ZI$$Length. This is to place heap at external SRAM.
Silence the following compiler warning:
[Warning] RTX_CM_lib.h@807,5: implicit declaration of function 'atexit' [-Wimplicit-function-declaration]

The config store tests use more than 2K of the interrupt stack, causing
an overflow. This patch bumps the K64F interrupt stack size to 4K
for ARMCC and GCC. The IAR interrupt stack is left untouched since
it is 32K.
Test the following components of the heap and stacks:
-Heap and interrupt stack are at the expected locations
-Entire heap can be used
-Heap limit is properly enforced and returns NULL when out of
of memory
Since the heap and stack are no longer shared, stack checking on the
main thread can be turned back on. This allows stack overflows on the
main thread to be caught quickly.
With the latest K64F linker file the initial stack is out of sync
with INITIAL_SP when uVisor is not present. This patch removes
the incorrect declaration.
Set well defined limits for the heap and configure GCC and ARMCC to
correctly check these. IAR already correctly checked its heap.
This also statically declares the main thread stack so the
linker is responsible for its placement.
In cmsis_os.h OS_TIMERS is undefined unless the timer thread is
disabled, in which case it is defined to 0. When comparing against
an undefined value, the undefined value will evaluate as if it were
0. Because of this the MAIN_THREAD_ID was always set to 0x1.
This patch fixes that problem by checking if OS_TIMERS is defined
before comparing it to 0.
This problem only effects IAR since it has a different heap/stack
layout. GCC_ARM and ARM have a dedicated stack region so
the presence of a guard word and stack checking does not cause
problems.
This problem manifested on the NRF51_DK in the pull request
https://github.com/mbedmicro/mbed/pull/2211
as a c_strings test failure on floating point. This is because the
guard word of the main stack overlapped with standard library
data used by sprintf and corrupted it.
Create the wrapper class SingletonPtr. This provides a safe way to
declare and use singletons. This class allows both the lazy
initialization of a singleton, and allows the singleton to be
garbage collected by the linker if it is never referenced.
This patch also updates the HAL to use SingletonPtr when declaring
singleton mutexes.
