| 220 | + device-driver that supports a CSF GPU. The duration value unit |
---|
| 221 | + is in micro-seconds and is used for configuring MCU shader Core power-off |
---|
| 222 | + timer. The configured MCU shader Core power-off timer will only have |
---|
| 223 | + effect when the host driver has delegated the shader cores |
---|
| 224 | + power management to MCU. The supplied value will be |
---|
| 225 | + recorded internally without any change. But the actual field |
---|
| 226 | + value will be subject to core power-off timer source frequency |
---|
| 227 | + scaling and maximum value limiting. The default source will be |
---|
| 228 | + SYSTEM_TIMESTAMP counter. But in case the platform is not able |
---|
| 229 | + to supply it, the GPU CYCLE_COUNTER source will be used as an |
---|
| 230 | + alternative. |
