1 What: /sys/bus/pci/drivers/xe/.../hwmon/hwmon<i>/power1_max 2 Date: September 2023 3 KernelVersion: 6.5 4 Contact: intel-xe@lists.freedesktop.org 5 Description: RW. Card reactive sustained (PL1) power limit in microwatts. 6 7 The power controller will throttle the operating frequency 8 if the power averaged over a window (typically seconds) 9 exceeds this limit. A read value of 0 means that the PL1 10 power limit is disabled, writing 0 disables the 11 limit. Writing values > 0 and <= TDP will enable the power limit. 12 13 Only supported for particular Intel Xe graphics platforms. 14 15 What: /sys/bus/pci/drivers/xe/.../hwmon/hwmon<i>/power1_rated_max 16 Date: September 2023 17 KernelVersion: 6.5 18 Contact: intel-xe@lists.freedesktop.org 19 Description: RO.
