From 8693a824873a0a97be77c1d5f1e98777f06f7305 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Fri, 3 May 2013 18:48:11 +0100 Subject: drm/i915: Add references to some workaround we implement We did not mention the workaround name when implementing those. This should help us track what we already implement.
