From 3ef98f50ca7cef5cc9b9bf89cd46830afbf4df68 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 11 Dec 2017 20:40:40 +0000 Subject: [PATCH] drm/i915: Print an error message for a reset failure on gen2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Since on gen2, we do not universally have a GPU reset implementation, we fail i915_reset() at intel_has_gpu_reset(). However, this is also intentionally disabled for CI testing and so it only has a debug message. Promote that debug message to a user-facing error message that should explain why their machine became unusable following the GPU hang.
