From 48b031e30d46b11fdf7a8075f02f5f9eef728f4d Mon Sep 17 00:00:00 2001 From: Mika Kuoppala Date: Tue, 25 Feb 2014 17:11:27 +0200 Subject: [PATCH] drm/i915: Add reset count to error state By default we keep only the error state from first hang. However some sneaky user might have cleared the first error state and we assume mistakenly that it is from first hang. As sometimes this matters, it is better to explicitly store the reset count.
