* 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.
|
* @ON_PMODE_ENTER_CORESIGHT_DISABLE: The MCU is on, protected mode enter is about to
|
* be requested, Coresight is being disabled.
|
* @ON_PMODE_EXIT_CORESIGHT_ENABLE : The MCU is on, protected mode exit has happened
|
* Coresight is being enabled.
|
* @CORESIGHT_DISABLE: The MCU is on and Coresight is being disabled.
|
* @CORESIGHT_ENABLE: The MCU is on, host does not have control and
|
* Coresight is being enabled.
