Add hwmon support for temp1_input attribute, which will expose package temperature in millidegree Celsius. With this in place we can monitor package temperature using lm-sensors tool. $ sensors i915-pci-0300 Adapter: PCI adapter in0: 990.00 mV fan1: 1260 RPM temp1: +45.0°C power1: N/A (max = 35.00 W) energy1: 12.62 kJ v2: Use switch case (Anshuman) v3: Comment adjustment (Riana) Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/11276 Signed-off-by: Raag Jadav <raag.jadav@intel.com> Reviewed-by: Anshuman Gupta <anshuman.gupta@intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Reviewed-by: Riana Tauro <riana.tauro@intel.com> Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240910105242.3357276-1-raag.jadav@intel.com

What: /sys/bus/pci/drivers/i915/.../hwmon/hwmon/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/bus/pci/drivers/i915/.../hwmon/hwmon/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.

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.

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.

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.
