Subject: [Intel-gfx] [PATCH 1/8] drm/i915: Add frontbuffer tracking tracepoints
Date: Wed, 14 Apr 2021 05:23:02 +0300	[thread overview]
Message-ID: <20210414022309.30898-2-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20210414022309.30898-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add some tracpoints for frontbuffer tracking so we can
try to figure out what's going on.
