From 40b2a687bd92827ca144d3623cf48377d8f7680d Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 15 Mar 2010 16:43:47 +1000 Subject: drm/nv50: add more 0x100c80 flushy magic Fixes the !vbo_fifo path in the 3D driver on certain chipsets. Still not really any good idea of what exactly the magic achieves, but it makes things work. While we're at it, in the PCIEGART path, flush on unbinding also.

We should now fail to load gracefully on detecting no VRAM, rather than something potentially messy happening.
