| 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. |
