From 96f298aa9c9fc9b7c8a2ebaf8c195d178f570e09 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Sat, 19 Mar 2011 18:14:27 -0700 Subject: drm/1915: ringbuffer wait for idle function Added a new function which waits for the ringbuffer space to be equal to (total - 8). This is the empty condition of the ringbuffer, and equivalent to head==tail. Also modified two users of this functionality elsewhere in the code.
