From f6086134d0b17b2c37f537a5429a919b3d2cced8 Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Sat, 16 Oct 2010 00:45:15 +0000 Subject: agp/amd-k7: Allow binding user memory to the AGP GART. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TTM-based DRM drivers need to be able to bind user memory to the AGP aperture. This patch fixes the "[TTM] AGP Bind memory failed." errors and the subsequent fallout seen with the nouveau driver.
