From 461e193971db4ac456be0d383e9aebf15868542a Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 17 May 2011 12:53:55 -0700 Subject: [PATCH] i965: Updated fixed-point sizes in Ivybridge SAMPLER_STATE. Texture LOD Bias is now S4.8 instead of S4.6; Min LOD, and Max LOD are now U4.8 instead of U4.6. Fixes piglit test tex-miplevel-selection.
