cortex_a55_smp/gnu: added barrier instruction before setting tx_thread_smp_lock_ready_bit #271

Closed phoenix037 closed 1 year ago

phoenix037 commented 1 year ago

Added barrier instruction before setting tx_thread_smp_lock_ready_bit in _tx_thread_context_restore() and _tx_thread_system_return() to ensure accesses to shared resources have completed. This ensures that _tx_thread_schedule() reads correct thread data when it sees tx_thread_smp_lock_ready_bit set. This update should be relevant for other Cortex-A SMP ports as well. However, the update has been tested only on the Cortex-A55 platform.
