Subject: [PATCH] drm/radeon: initialize AFMT blocks on DCE6
Date: Wed, 31 Jul 2013 18:51:53 +0200 [thread overview]
Message-ID: <1375289513-3328-1-git-send-email-zajec5@gmail.com> (raw)
So far it was tested on HD7750 (DCE6) only. For DCE61 and DCE64 I
assumed that amount of AFMTs equals amount of display controllers.
