From 891517f5111cd82909906d5e8ee0299db0d46762 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 7 Jan 2013 13:07:13 +1000 Subject: nouveau: disallow pushbuf BOs in multiple memory types Under certain circumstances it's possible for libdrm to decide to move a GART|VRAM pushbuf to be VRAM-only. This causes the kernel to reject the command submission on GF8 and up, due to a stricter policy where buffers are only allowed to move to memory types that were specified at creation time. The simplest fix for this is to force the creation-time memory type for the lifetime of the push buffer.
