This one actually looks OK to me. Unless I typoed the numbers the timings give us a vrefresh of 59.58 which gets rounded to 60. So no change once .vrefresh disappears AFAICS. -- Ville Syrjälä Intel _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 10+ messages in thread

Hi Sam, Thank you very much for your review. I did consider this. The reason I combined the patches, is that the binding depends on the display so I thought they were related in some way. Didn't know the correct procedure to handle this.

Just like Ville Syrjälä, I ran the numbers and vrefresh indeed calculates to 59.58. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 10+ messages in thread
