| * Backend-specific Power Manager MCU state definitions. |
| * The function-like macro KBASEP_MCU_STATE() must be defined before including |
| * this header file. This header file can be included multiple times in the |
| * same compilation unit with different definitions of KBASEP_MCU_STATE(). |
| * |
| * @OFF: The MCU is powered off. |
| * @PEND_ON_RELOAD: The warm boot of MCU or cold boot of MCU (with |
| * firmware reloading) is in progress. |
| * @ON_GLB_REINIT_PEND: The MCU is enabled and Global configuration |
| * requests have been sent to the firmware. |
| * @ON_HWCNT_ENABLE: The Global requests have completed and MCU is now |
| * ready for use and hwcnt is being enabled. |
| * @ON: The MCU is active and hwcnt has been enabled. |
| * @ON_CORE_ATTR_UPDATE_PEND: The MCU is active and mask of enabled shader cores |
| * is being updated. |
| * @ON_HWCNT_DISABLE: The MCU is on and hwcnt is being disabled. |
| * @ON_HALT: The MCU is on and hwcnt has been disabled, MCU |
| * halt would be triggered. |
| * @ON_PEND_HALT: MCU halt in progress, confirmation pending. |
| * @POWER_DOWN: MCU halted operations, pending being disabled. |
| * @PEND_OFF: MCU is being disabled, pending on powering off. |
| * @RESET_WAIT: The GPU is resetting, MCU state is unknown. |
| * @HCTL_SHADERS_PEND_ON: Global configuration requests sent to the firmware |
| * have completed and shaders have been requested to |
| * power on. |
| * @HCTL_CORES_NOTIFY_PEND: Shader cores have powered up and firmware is being |
| * notified of the mask of enabled shader cores. |
| * @HCTL_MCU_ON_RECHECK: MCU is on and hwcnt disabling is triggered |
| * and checks are done to update the number of |
| * enabled cores. |
| * @HCTL_SHADERS_READY_OFF: MCU has halted and cores need to be powered down |
| * @HCTL_SHADERS_PEND_OFF: Cores are transitioning to power down. |
| * @HCTL_CORES_DOWN_SCALE_NOTIFY_PEND: firmware has been informed to stop using |
| * specific cores, due to core_mask change request. |
| * After the ACK from FW, the wait will be done for |
| * undesired cores to become inactive. |
| * @HCTL_CORE_INACTIVE_PEND: Waiting for specific cores to become inactive. |
| * Once the cores become inactive their power down |
| * will be initiated. |
| * @HCTL_SHADERS_CORE_OFF_PEND: Waiting for specific cores to complete the |
| * transition to power down. Once powered down, |
| * HW counters will be re-enabled. |
| * @ON_SLEEP_INITIATE: MCU is on and hwcnt has been disabled and MCU |
| * is being put to sleep. |
| * @ON_PEND_SLEEP: MCU sleep is in progress. |
| * @IN_SLEEP: Sleep request is completed and MCU has halted. |
