From dfd9c1b4eab124c16c3b59362c3640983bf79949 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 11 Nov 2019 11:43:22 +0000 Subject: [PATCH] drm/i915: Show guilty context name on GPU reset We mention that we are resetting the GPU, and dump the device state for post mortem debugging. However, while that dump contains the active processes and the one flagged as causing the error, we do not always include that information in dmesg. Include the name of the guilty process in dmesg for reference.
