What: /sys/bus/pci/drivers/xe/.../hwmon/hwmon/power1_max Date: September 2023 KernelVersion: 6.5 Contact: intel-xe@lists.freedesktop.org Description: RW. Card reactive sustained (PL1) 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 and <= TDP will enable the power limit.
