From 20abd1634a6e2eedb84ca977adea56b8aa06cc3e Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 30 Apr 2012 11:33:43 -0500 Subject: drm/nouveau: create real execution engine for software object class Just a cleanup more or less, and to remove the need for special handling of software objects. This removes a heap of documentation on dma/graph object formats. The info is very out of date with our current understanding, and is far better documented in rnndb in envytools git.
