From 461bc9b587389586edf9315b337fb136f33594ad Mon Sep 17 00:00:00 2001 From: Eugeni Dodonov Date: Wed, 9 May 2012 15:37:11 -0300 Subject: [PATCH] drm/i915: calculate watermarks for devices that have 3 pipes This adds proper support for calculating those watermarks, checking for number of available pipes instead of specific GPU variants when deciding if watermarks for 3rd pipe are necessary.
