From 8ad305f1a29a8c06586aaef87443ce14936aac30 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 19 Nov 2019 10:09:13 +0000 Subject: [PATCH] drm/i915/gem: Manually dump the debug trace on GEM_BUG_ON Since igt now defaults to not enabling ftrace-on-oops, we need to manually invoke GEM_TRACE_DUMP() to see the debug log prior to a GEM_BUG_ON panicking.
