Rajkumar Kanagaraj 89e2124d4a HW Watchdog and SW watchdog interface
- Added Hw watchdog periodic kick calls software watchdog is_alive check
2019-07-11 11:55:14 +01:00
Rajkumar Kanagaraj 02b319f3c7 Add SW Watchdog
-SW watchdog has interface name start(),stop(),kick()	Sw watchdog internally has static list and shared across multiple instance of SW watchdog
	- Sw watchdog initialize timeout value,unique string via constructor whenever threads created sw watchdog object
	-Threads make sure pass proper timeout value,Unique string while creating the instance.
	-start() called by components(BLE,WIFI etc.,),it adds the entry into static list with few details current count ,etc.,
	-kick() called by registered components(BLE,WIFI etc.) to reset current count to zero.
        -is_alive - interface API to mbed_watchdog_manager
        -implementation optimization
2019-07-11 11:55:13 +01:00
Rajkumar Kanagaraj 1ab851bacf Add HwWatchdog
- mbed_watchdog_mgr has interface name mbed_wdog_manager_start(),mbed_wdog_manager_stop(),mbed_wdog_manager_kick()
    - HwWatchdog is going to attach with LowPowerTIcker for periodic callback functionality
    - mbed_wdog_manager_start() will either get start either by BL/RTOS Aps,it reads the timeout value specified via macro and macro gets defined in target.json file.
    - mbed_wdog_manager_start() internally configure below HAL hw watchdog with timeout specified via target.json
    - mbed_wdog_manager_start() internally divide the timeout(specified in target.json) by the 2 and attach LowPowerTicker with periodic callback of hw_kick()
    - mbed_wdog_manager_start() internally create one instance of sw watchdog class,to access the static list data structure of sw watchdog class
    - mbed_wdog_manager_kick() function periodically get called and refresh the hw watchdog to avoid watchdog reset
    - converted C++ code into C based APIs
    - added boolean to control watchdog start and stop
    - Added detach from ticker on stop API

Russ Butler 0b316ca72f Add newline after mbed error so greentea shows it
When the function `error` is called without ending in a newline
greentea will not display the error. This is because greentea is
performing line buffering.

This patch ensures that all calls to `error` end with a newline. This
is done by adding an additional newline to end end of the string.

Example code exhibiting this problem:
error("This function is not supported.");

Kevin Bracey a8fdcdee69 Remote "static" from MBED_FORCEINLINE
Static keyword causes problems when trying to use force-inlined
functions from normal inlined functions. This is not legal:

    static inline void forced() { }

    inline void normal() { forced(); }

You cannot reference internal-linkage things from external-linkage
inline functions.

Removal of the static implies that in C there would need to be a
non-inline definition in case anyone calls it non-inlined, but if the
force attribute is doing its job, that should not happen.

Only significant in-tree user of the MBED_FORCEINLINE macro is
the atomic operations - making this change permits atomic operations
from non-static inline functions.

Kevin Bracey d571990298 wait_ns micro-optimisation
Use `+ 1` to set the "Thumb" indicator on the `delay_loop` routine
address, rather than `| 1`. That makes it something that can be done
by the linker, rather than needing to be done at run-time.

Saves one instruction and one cycle.

Kevin Bracey 0d12800b9f wait_us optimization
As the timer code became more generic, coping with initialization on
demand, and variable width and speed us_ticker_api implementations,
wait_us has gradually gotten slower and slower.

Some platforms have reportedly seen overhead of wait_us() increase from
10µs to 30µs. These changes should fully reverse that drop, and even
make it better than ever.

Add fast paths for platforms that provide compile-time information about
us_ticker. Speed and code size is improved further if:

* Timer has >= 2^32 microsecond range, or better still is 32-bit 1MHz.
* Platform implements us_ticker_read() as a macro
* Timer is initialised at boot, rather than first use

The latter initialisation option is the default for STM, as this has
always been the case.

Kevin Bracey 648cbf30db Atomics: GCC fix for M23 (ARMv8-M baseline)
Add unified syntax directives to make the atomic assembler work when GCC
is building for M23.

GCC actually uses unified syntax when compiling C code, but puts
`.syntax divided` before each piece of inline assembly when targetting
Thumb-1 type devices like M0 and M23 for backwards compatibility. We can
overcome this with our own `.syntax unified`.  The command-line option
`-masm-syntax-unified` intended to override this globally has been
broken from GCC 6 to 8.0.

Kevin Bracey 3a2bd249c6 Fix ARMC5 compilation
Minor tweaks to fix ARM C 5 compatibility.

Pushing "ns_list.h" include to first makes sure "ns_types.h" is included
first, meaning it gets to define `__STDC_LIMIT_MACROS` before the first
include of <stdint.h>, which ensures that UINT8_MAX etc are defined.

Kevin Bracey 2bb40450ec Add non-volatile atomic loads and stores
Volatile makes no real difference when we're using assembler, or locked
functions, but leaving it off could be more efficient for the basic
loads and stores. So add non-volatile overloads in C++ for them.

Kevin Bracey 87396e0bf6 Assembler atomics
Reimplement atomic code in inline assembly. This can improve
optimisation, and avoids potential architectural problems with using
LDREX/STREX intrinsics.

API further extended:
* Bitwise operations (fetch_and/fetch_or/fetch_xor)
* fetch_add and fetch_sub (like incr/decr, but returning old value -
  aligning with C++11)
* compare_exchange_weak
* Explicit memory order specification
* Basic freestanding template overloads for C++

This gives our existing C implementation essentially all the functionality
needed by C++11.

An actual Atomic<T> template based upon these C functions could follow.

Kevin Bracey b8e80dd2fb Don't trap RTX errors or mutex errors during errors
Once a fatal error is in progress, it's not useful to trap RTX errors
or mutex problems, so short-circuit the checks.

This makes it more likely that we may be able to get the console
initialised if it is being written to for the first time by `mbed_error`
in a difficult context - such as an RTX error callback from inside an
SVCall.

For example, the one-line program

   osMutexAcquire(NULL, 0);

will generate an RTX error trap, then `mbed_error` will try to call
`write(STDERR_FILENO)` to print the error, which will prompt mbed_retarget to
construct a singleton `UARTSerial`. This would trap in the mutex
for the singleton or the construction of the UARTSerial itself, if
we didn't allow this leniency. If we clear the mutex checks, then
`UARTSerial::write_unbuffered` will work.

Kevin Bracey a4010942eb mbed_error: Avoid negative left shift
User uses of `MBED_MAKE_ERROR` assemble a new error that gets its bottom
16 bits from an existing negative 32-bit error code. This lead to
undefined behaviour when `<<` was used on it - even though it was a
shift by zero!

Avoid the undefined behaviour warning from Clang by masking before
shifting.
