| Description: RO. Current Voltage in millivolt. | |
| Only supported for particular Intel i915 graphics platforms. | |

| Contact: intel-gfx@lists.freedesktop.org | |
| Description: RW. Card reactive sustained (PL1/Tau) power limit in microwatts. | |
| The power controller will throttle the operating frequency | |
| if the power averaged over a window (typically seconds) | |
| exceeds this limit. A read value of 0 means that the PL1 | |
| power limit is disabled, writing 0 disables the | |
| limit. Writing values > 0 will enable the power limit. | |
| Only supported for particular Intel i915 graphics platforms. | |

| Description: RO. Card default power limit (default TDP setting). | |
| Only supported for particular Intel i915 graphics platforms. | |

| Description: RW. Sustained power limit interval (Tau in PL1/Tau) in | |
| milliseconds over which sustained power is averaged. | |
| Only supported for particular Intel i915 graphics platforms. | |

| Description: RW. Card reactive critical (I1) power limit in microwatts. | |
| Card reactive critical (I1) power limit in microwatts is exposed | |
| for client products. The power controller will throttle the | |
| operating frequency if the power averaged over a window exceeds | |
| this limit. | |
| Only supported for particular Intel i915 graphics platforms. | |

| Description: RW. Card reactive critical (I1) power limit in milliamperes. | |
| Card reactive critical (I1) power limit in milliamperes is | |
| exposed for server products. The power controller will throttle | |
| the operating frequency if the power averaged over a window | |
| exceeds this limit. | |
| Only supported for particular Intel i915 graphics platforms. | |

| Description: RO. Energy input of device or gt in microjoules. | |
| For i915 device level hwmon devices (name "i915") this | |
| reflects energy input for the entire device. For gt level | |
| hwmon devices (name "i915_gtN") this reflects energy input | |
| for the gt. | |
| Only supported for particular Intel i915 graphics platforms. |
