From 0d5c60edf11fdded738acf3f78a0c667599cd60d Mon Sep 17 00:00:00 2001 From: Jamie Gennis Date: Wed, 9 Oct 2013 17:49:37 -0700 Subject: DispSync: don't compensate for wakeup latency This change removes the wakeup latency compensation from the software-generated vsync events. Choreographer can't handle timestamps in the future, so don't aim for early wake-ups with the expectation that the actual wake-up will be late.
