From 20d9286f71253004a91acbcf4c257e84ee7df077 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 29 Nov 2012 01:10:19 -0800 Subject: i965: Rework 3DSTATE_VS for Broadwell. v2: Remove incorrect MOCS shifts; rename urb_entry_write_offset to urb_entry_output_offset to closer match the documentation. v3: Only emit a non-zero constant buffer read length when active. v4: Add missing binding table counts (caught by Eric). v5: Rebase on Paul Berry's changes to CurrentVertexProgram. v6: Drop bogus SBE read length/offset field code. We were programming the wrong values, and our 3DSTATE_SBE code overrides any value we put here anyway with the correct one.
