From 7592f005608e6c03d53c18d27d9af84bde802014 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 11 May 2011 13:08:03 -0700 Subject: [PATCH] i965/fs: Drop the viewport index/rtai clearing in gen6 fb writes. These fields are documented to be in the payload, and though the FB write docs say they *aren't* in the payload, for all other fields the payload and header is structured so that no overwriting is required except for non-default options. --- src/mesa/drivers/dri/i965/brw_fs.cpp | 6 ------ 1 file changed, 6 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_fs.cpp b/src/mesa/drivers/dri/i965/brw_fs.cpp index 5232a7f77af..2157c935711 100644 --- a/src/mesa/drivers/dri/i965/brw_fs.cpp +++ b/src/mesa/drivers/dri/i965/brw_fs.cpp @@ -2330,12 +2330,6 @@ fs_visitor::generate_fb_write(fs_inst *inst) brw_imm_ud(inst->target)); } - /* Clear viewport index, render target array index. */ - brw_AND(p, retype(brw_vec1_reg(BRW_MESSAGE_REGISTER_FILE, 0, 0), - BRW_REGISTER_TYPE_UD), - retype(brw_vec1_grf(0, 0), BRW_REGISTER_TYPE_UD), - brw_imm_ud(0xf7ff)); - implied_header = brw_null_reg(); } else { implied_header = retype(brw_vec8_grf(0, 0), BRW_REGISTER_TYPE_UW); -- 2.30.2
