From df2b23d97919601218e9229ff517afea83fe5520 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 27 Nov 2012 17:06:54 +0000 Subject: [PATCH] drm/i915: Include the last semaphore sync point in the error-state Should be useful to know what the driver thought the other ring's seqno was when it last used a semaphore.
