Turn the compile time error issued when a NonCopyable resource is copied
into a compile time and runtime warning.
If the application is compiled with the debug profile the compile time
error remains.
The compile time error can be enforced by setting the library option
force-non-copyable-error to true.
This patch deprecates the CallChain class since it is an
internal API (not in mbed.h) and is only being used by
InterruptManager which is also deprecated.
Add weak implementations of *_ticker_get_info which returns 1MHz and
a width of 32 bits. This allows the updated Ticker API to work with
existing devices.
Note - in the future when all targets have implemented
*_ticker_get_info these weak functions will be removed.
Spinning while polling is overly CPU intensive, and inconsistent with
the current blocking behaviour of UARTSerial.
Change to use Thread::wait(1) to match UARTSerial.
Add _lock_count to DeepSleepLock and use this to prevent deep sleep
from staying locked when the DeepSleepLock objected is destroyed after
an unbalanced number of calls to lock and unlock.
Update platform code to use the ticker common layer rather than using
HAL us ticker directly. This both ensures that the underlying ticker
is properly initialized and that the value read is in microseconds with
full 32-bit range.
GCC's newlib library depends on fstat to get in-flight information about
a file's type an size. A working fstat for regular files is needed for
seek and related functions to work correctly.
This change prevents inclusion of non throwing versions of the new operator from
the compiler standard library. On GCC, the non throwing version bring with it
some portion of the exception support code.
When the RTOS is present and the tickless mode is not implemented, it is
expected that the next tick issued by the Systick timer will wake up the MCU.
However nothing prevents an implementation of the ARM architecture to gate the
systick clock signal upon sleep entry.
Therefore on those targets sleep shall be prohibited if the RTOS is present and the
tickless mode is not implemented.
To ease life of porters , a new option has been added in the device add list:
STCLK_OF_DURING_SLEEP. This option expose that the target turn of the systick
clock during sleep.
Targets which exhibit such behavior shall add this define in their device_has list.
