Christopher Haster 54609f6d62 Added default value for MBED_CONF_CORE_STDIO_CONVERT_NEWLINES 2016-06-17 03:54:39 -05:00
Christopher Haster 1480c231e9 Added config option for newline conversion 2016-06-15 21:14:26 -05:00
Christopher Haster 2330dcc49a Added newline conversion for stdin
stdin converts the following character sequences:

\n   -> \n
\r\n -> \n
\r   -> \n
\n\r -> \n

For original behaviour, a serial object can be instantiated explicitly

Jaeden Amero af572350f0 Don't call __disable_irq for uVisor
This is a hack to get debug builds applications that use uVisor to work.
The assertions in core_util_critical_section fail because interrupts can't
actually be disabled from unprivileged mode.

Without this hack, core_util_critical_section_enter() calls
mbed_assert_internal() when the assertion fails, which calls
core_util_critical_section_enter() again, which calls
mbed_assert_internal() again; this is infinite recursion.

core_util_critical_section_enter needs some fixing.

0xc0170 81a7bdc482 critical - fix __STDC_LIMIT_MACROS for armcc
UINT32_MAX is defined only if __STDC_LIMIT_MACROS is provided prior
including stdint.h

0xc0170 3b2d75fcda error - include interface header file

Russ Butler 8c2e352dd8 Fix GCC malloc lock
The malloc lock functions were not declared as extern "C" so they
are not getting linked to the standard library.  Add extern "C" to
fix this.

This bug was introduced in the commit:

Fix duplicate symbols for malloc lock and unlock

Russ Butler d0b7b3b497 Fix duplicate symbols for malloc lock and unlock
When the malloc lock and unlock functions are inside a library they
conflict with the standard libraries weak version of these functions.
This is because of the way weak references are handled by the linker.
This patch renames the lock and unlock functions defined inside RTX
so they do not conflict.  A thunk inside retarget.cpp then calls the
RTX functions.  This problem does not occur with retarget.cpp since
it is always build into an object file rather than a library file.

Russ Butler b174d6a314 Add virtual lock for thread safe classes
Add a virtual lock for the classes which are thread safe.  This
allows the use of a mutex to be overridden.

Russ Butler e4f6e1b327 Update assert and error to be interrupt safe
Add printf functions intended for errors which are safe to call from
interrupts.  Update assert and error to use this function.

Russ Butler feb60784e9 Make core mbed API thread safe
Make the mbed C++ API thread safe by adding a combination of
mutexes and critical sections.  Stub out all mutexes when the
RTOS is not present.

Niklas Hauser f81cf5d686 Add default implementation of malloc wrapping
For GCC malloc is always wrapped, but only used for FEATURE_UVISOR.
Otherwise we have to simply forward the wrappers.

Jaeden Amero 5d48984914 Initialize uvisor-lib
uvisor-lib has an init function that must be called before the RTOS kernel
is initialized. Call uvisor_lib_init from software_init_hook to accomplish
this.

Jaeden Amero 43e595aec3 Wrap software_init_hook
Wrap software_init_hook so that it can be used or extended from outside the
RTOS. This is desirable so that code can be added to the software_init_hook
without making the RTOS depend on new features or libraries.

0xc0170 b5c4faf6f6 Critical section - fix for cortex-a
Cortex-A does not contain primask, there's 7th bit in the CPSR register,
that contains this information. Fixes #1851.

Renames primask variables to interrupts_disabled.

Russ Butler f3b1d45963 Add functions for atomic access

compare and set.

Russ Butler bd216c37cb Make the IAR standard library thread safe
Add the locks and flags necessary to make the IAR standard library
thread safe.  These changes consist of:
-Add compiler flag "--guard_calls" to ensure C++ function-static
    variables with dynamic initializers are initialized in a
    thread safe manner
-Add the linker flag "--threaded_lib" so the thread safe version of
    the standard library is used
-Implement mutex functions required for IAR thread safety
-Create a set of stub functions in retarget.c for when the rtos is not present

Sam Grove 284bd081b4 Remove __enable and __disable irq calls from mbed hal common code 2016-05-28 17:19:55 +08:00
Kevin Bracey 4422884c16 Use critical section helper in HAL
Routines using __disable_irq and __enable_irq had the effect of
enabling interrupts if called with interrupts disabled.

Some versions of __disable_irq do not return old status to restore it.

Change to use the critical section helper functions instead.

Anna Bridge 462c917ad0 Add a c based re-entrant critical section API
This includes a generic critical section implementation.  This
implementation also allow a user to start a critical section while
interrupts are already disabled.
