From: Ville Syrjälä <ville.syrj...@linux.intel.com> I've mentioned before that I had a patch to re-enable FIFO underrun reporting after a certain time. Well, here it is.
Based on the recent quick discussion I also took the opportunity to convert GMCH platforms to use the same underrung reporting logic as we use for PCH platforms. And then, there's a patch to make underrun reports DRM_ERRORs. Not sure how many bug reports we'd be getting, but we should do that eventually anyway. We do have some cases (eg. too much sprite scaling vs. cdclk frequency) that can cause underruns currently, and the watermark code still has some issues, but under typical use w/o sprites, I wouldn't expect underruns.
