13 Description:    RW. Card reactive sustained  (PL1/Tau) power limit in microwatts.
15                 The power controller will throttle the operating frequency
16                 if the power averaged over a window (typically seconds)
17                 exceeds this limit. A read value of 0 means that the PL1
18                 power limit is disabled, writing 0 disables the
19                 limit. Writing values > 0 will enable the power limit.
21                 Only supported for particular Intel i915 graphics platforms.
