Ville Syrjälä 4003dac180 drm/i915: Clamp linetime wm to <64usec ... The linetime watermark is a 9 bit value, which gives us a maximum linetime of just below 64 usec. If the linetime exceeds that value we currently just discard the high bits and program the rest into the register, which angers the state checker. To avoid that let's just clamp the value to the max. I believe it should be perfectly fine to program a smaller linetime wm than strictly required, just means the hardware may fetch data sooner than strictly needed. We are further reassured by the fact that with DRRS the spec tells us to program the smaller of the two linetimes corresponding to the two refresh rates.
