| * Backend-specific Power Manager shader core state definitions. |
| * The function-like macro KBASEP_SHADER_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_SHADER_STATE(). |
| * |
| * @OFF_CORESTACK_OFF: The shaders and core stacks are off |
| * @OFF_CORESTACK_PEND_ON: The shaders are off, core stacks have been |
| * requested to power on and hwcnt is being |
| * disabled |
| * @PEND_ON_CORESTACK_ON: Core stacks are on, shaders have been |
| * requested to power on. Or after doing |
| * partial shader on/off, checking whether |
| * it's the desired state. |
| * @ON_CORESTACK_ON: The shaders and core stacks are on, and |
| * hwcnt already enabled. |
| * @ON_CORESTACK_ON_RECHECK: The shaders and core stacks are on, hwcnt |
| * disabled, and checks to powering down or |
| * re-enabling hwcnt. |
| * @WAIT_OFF_CORESTACK_ON: The shaders have been requested to power |
| * off, but they remain on for the duration |
| * of the hysteresis timer |
| * @WAIT_GPU_IDLE: The shaders partial poweroff needs to |
| * reach a state where jobs on the GPU are |
| * finished including jobs currently running |
| * and in the GPU queue because of |
| * GPU2017-861 |
| * @WAIT_FINISHED_CORESTACK_ON: The hysteresis timer has expired |
| * @L2_FLUSHING_CORESTACK_ON: The core stacks are on and the level 2 |
| * cache is being flushed. |
| * @READY_OFF_CORESTACK_ON: The core stacks are on and the shaders are |
| * ready to be powered off. |
| * @PEND_OFF_CORESTACK_ON: The core stacks are on, and the shaders |
| * have been requested to power off |
| * @OFF_CORESTACK_PEND_OFF: The shaders are off, and the core stacks |
| * have been requested to power off |
| * @OFF_CORESTACK_OFF_TIMER_PEND_OFF: Shaders and corestacks are off, but the |
| * tick timer cancellation is still pending. |
| * @RESET_WAIT: The GPU is resetting, shader and core |
| * stack power states are unknown |
