From 7a73390f9126fd270d9891cd9d2bf38ef56d9b80 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Thu, 29 Jul 2010 14:51:06 -0400 Subject: r600g: mipmap early support + EX2/ABS instruction + culling Add mipmap support (demos/src/redbook/mipmap is working) Add EX2/ABS shader instruction support. Add face culling support. Misc fixes.
