+What: /sys/devices/.../hwmon/hwmon<i>/in0_input
+Date: February 2023
+KernelVersion: 6.2
+Contact: intel-gfx@lists.freedesktop.org
+Description: RO. Current Voltage in millivolt.
+
+ Only supported for particular Intel i915 graphics platforms.
+
+What: /sys/devices/.../hwmon/hwmon<i>/power1_max
+Date: February 2023
+KernelVersion: 6.2
+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.

+What: /sys/devices/.../hwmon/hwmon<i>/power1_max_interval
+Date: February 2023
+KernelVersion: 6.2

+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.
