From 7411f9cfe67f5dd54333d2fe7e2a677c42666f99 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Sun, 11 Mar 2012 21:11:22 -0500 Subject: [PATCH] staging: drm/omap: use current time for page-flip event Because we don't have vblank hooked up via drm_irq (which is a bit awkward due to separation between omapdss (which knows the irq #) and omapdrm, for now use gettimeofday to have a semi-sane timestamp in the page-flip event. Otherwise apps like weston drm compositor, which use the timestamp in it's animations, get highly confused.
