From c79057922ed6c2c6df1214e6ab4414fea1b23db2 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 16 Apr 2014 16:56:09 +0200 Subject: [PATCH] drm/i915: Remove vblank wait from haswell_write_eld MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The pipe is off at that point in time, so a vblank wait is simply a 50ms wait. Caught by Jesse's verbose "make vblank wait timeouts WARN" patch. We've probably had a few versions of this float around already. To document assumptions put a pipe assert into the same place. And also add a posting read. If we ever decide to update the eld and infoframes while the pipe is already on (e.g. for fastboot) then there's lots of work to do. So better properly document all the hidden assumptions. Reviewed-by: Ville Syrjälä Signed-off-by: Daniel Vetter --- Reading git-format-patch failed
