From fb3256da8db2cb70be7d2c7f058b8676a9a85aaf Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 11 Apr 2012 22:12:56 +0200 Subject: [PATCH] drm/i915: split up ring->dispatch_execbuffer functions Now that we can, we should split them up in a way that makes some sense and banishes the IS_ checks into init code.
