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.
|
|
|
|
Only supported for particular Intel Xe graphics platforms.
