1What: /sys/bus/pci/drivers/xe/.../hwmon/hwmon<i>/power1_max
2Date: September 2023
3KernelVersion: 6.5
4Contact: intel-xe@lists.freedesktop.org
5Description: 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.
