From 58dc8b7db5829188dbb45c020ab44732d6053888 Mon Sep 17 00:00:00 2001 From: Gary Wong Date: Wed, 29 Oct 2008 19:53:33 -0400 Subject: [PATCH] i965: support destination horiz strides in align1 access mode. This is required for scatter writes in destination regions to work. --- src/mesa/drivers/dri/i965/brw_eu.h | 2 +- src/mesa/drivers/dri/i965/brw_eu_emit.c | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_eu.h b/src/mesa/drivers/dri/i965/brw_eu.h index 207b8b7ca38..8cbe4215fbf 100644 --- a/src/mesa/drivers/dri/i965/brw_eu.h +++ b/src/mesa/drivers/dri/i965/brw_eu.h @@ -65,7 +65,7 @@ struct brw_reg GLuint abs:1; /* source only */ GLuint vstride:4; /* source only */ GLuint width:3; /* src only, align1 only */ - GLuint hstride:2; /* src only, align1 only */ + GLuint hstride:2; /* align1 only */ GLuint address_mode:1; /* relative addressing, hopefully! */ GLuint pad0:1; diff --git a/src/mesa/drivers/dri/i965/brw_eu_emit.c b/src/mesa/drivers/dri/i965/brw_eu_emit.c index 0bfbec9d140..460521615c6 100644 --- a/src/mesa/drivers/dri/i965/brw_eu_emit.c +++ b/src/mesa/drivers/dri/i965/brw_eu_emit.c @@ -64,7 +64,7 @@ static void brw_set_dest( struct brw_instruction *insn, if (insn->header.access_mode == BRW_ALIGN_1) { insn->bits1.da1.dest_subreg_nr = dest.subnr; - insn->bits1.da1.dest_horiz_stride = BRW_HORIZONTAL_STRIDE_1; + insn->bits1.da1.dest_horiz_stride = dest.hstride; } else { insn->bits1.da16.dest_subreg_nr = dest.subnr / 16; @@ -78,7 +78,7 @@ static void brw_set_dest( struct brw_instruction *insn, */ if (insn->header.access_mode == BRW_ALIGN_1) { insn->bits1.ia1.dest_indirect_offset = dest.dw1.bits.indirect_offset; - insn->bits1.ia1.dest_horiz_stride = BRW_HORIZONTAL_STRIDE_1; + insn->bits1.ia1.dest_horiz_stride = dest.hstride; } else { insn->bits1.ia16.dest_indirect_offset = dest.dw1.bits.indirect_offset; -- 2.30.2
