.. _OPAL_CONFIG_CPU_IDLE_STATE: OPAL_CONFIG_CPU_IDLE_STATE ========================== .. code-block:: c #define OPAL_CONFIG_CPU_IDLE_STATE 99 /* * Setup and cleanup method for fast-sleep workarounds * state = 1 fast-sleep * enter = 1 Enter state * exit = 0 Exit state */ #define OPAL_PM_SLEEP_ENABLED_ER1 0x00080000 /* with workaround */ int64_t opal_config_cpu_idle_state(uint64_t state, uint64_t enter); If the `OPAL_PM_SLEEP_ENABLED_ER1` bit is set on a stop state, then this OPAL call needs to be made upon entry and exit of stop state. This is currently needed for the `fastsleep_` idle state, present on POWER8 systems. Returns ------- :ref:`OPAL_SUCCESS` Applied workaround :ref:`OPAL_PARAMETER` Invalid state or enter/exit.
