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. What: /sys/devices/.../hwmon/hwmon<i>/power1_rated_max Date: February 2023 KernelVersion: 6.2 Contact: intel-gfx@lists.freedesktop.org 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 Contact: intel-gfx@lists.freedesktop.org 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. What: /sys/devices/.../hwmon/hwmon<i>/power1_crit Date: February 2023 KernelVersion: 6.2 Contact: intel-gfx@lists.freedesktop.org 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. What: /sys/devices/.../hwmon/hwmon<i>/curr1_crit Date: February 2023 KernelVersion: 6.2 Contact: intel-gfx@lists.freedesktop.org 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. What: /sys/devices/.../hwmon/hwmon<i>/energy1_input Date: February 2023 KernelVersion: 6.2 Contact: intel-gfx@lists.freedesktop.org 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.
