* 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
