Created attachment 101826 [details] [review] Only reuse already active batches. I just want to check how painful this is in practice first. Throughput testing of that patch seems fine. Please see if it prevents the incoherent read. commit 157e22cb8e96b0a9ffa7d58625fe2396f6084ff9 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jun 26 20:19:52 2014 +0100 sna: Only reuse pinned batches for 830/845 Trying to fly too close to the sun. :( Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=80558 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Please do reopen if the problem persists.
