[Intel-gfx] [PATCH v4 01/23] drm/i915/xelpd: Enhanced pipe underrun reporting

2021-05-14 Thread Matt Roper
XE_LPD brings enhanced underrun recovery: the hardware can somewhat mitigate underruns by using an interpolated replacement pixel (soft underrun) or the previous pixel (hard underrun). Furthermore, underruns can now be caused downstream by the port, even if the pipe itself is operating properly.
