CONFIG_SOC_POSIX¶
Native POSIX port
Type: bool
Help¶
SOC for to the POSIX arch. It emulates a CPU running at an infinitely fast clock. That means the CPU will always run in zero time until completion after each wake reason (e.g. interrupts), before going back to idle. Note that an infinite loop in the code which does not sleep the CPU will cause the process to appear “hung”, as simulated time does not advance while the CPU does not sleep. Therefore do not use busy waits while waiting for something to happen (if needed use k_busy_wait()). Note that the interrupt handling is provided by the board.
