| 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. | |
| On DG2 the driver always shows two fan channels, because the | |
| FSC_READ_NUM_FANS command does not work on some cards. OEMs | |
| decide how the fans map to tach channels, so two fans can share | |
| one tach line. When that happens, the second channel | |
| reads 0 RPM even though the fan is spinning. This is normal, not | |
| a bug. | |
