| 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: 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. |

| 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. |

| 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. |
