From: Pauli Nieminen Date: Tue, 12 Jun 2012 18:38:50 +0000 (+0300) Subject: nouveau: Add support for ARB_sampler_objects X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=54808e560f773f652919a2865c7371e4715df510;p=mesa.git nouveau: Add support for ARB_sampler_objects ARB_sampler_objects is very simple software only extension to support. I want to make it a mandatory extension for Mesa drivers to allow the meta module to use it. This patch add support for the extension to nouveau. It is completely untested search and replace patch, except for flagging the texture state as needing to be recomputed when a sampler object is present.
