From: Francisco Jerez Date: Sat, 16 Oct 2010 00:45:15 +0000 (+0000) Subject: agp/amd-k7: Allow binding user memory to the AGP GART. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6086134d0b17b2c37f537a5429a919b3d2cced8;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git agp/amd-k7: Allow binding user memory to the AGP GART. 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.
