+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

+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:	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.
