From 9490d86808300e5819941a40784e272c290e05ee Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 5 May 2009 14:05:54 -0700 Subject: i965: Disentangle VS constant surface state from WM surface state. Also, only create VS surface state if there's a VS constant buffer to be uploaded, and set the contents of the buffer at the same time as creation. --- src/mesa/drivers/dri/i965/Makefile | 1 + src/mesa/drivers/dri/i965/brw_curbe.c | 15 -- src/mesa/drivers/dri/i965/brw_misc_state.c | 5 +- src/mesa/drivers/dri/i965/brw_state.h | 20 ++ src/mesa/drivers/dri/i965/brw_state_upload.c | 3 +- src/mesa/drivers/dri/i965/brw_vs_surface_state.c | 226 +++++++++++++++++++++++ src/mesa/drivers/dri/i965/brw_wm_surface_state.c | 171 +---------------- 7 files changed, 255 insertions(+), 186 deletions(-) create mode 100644 src/mesa/drivers/dri/i965/brw_vs_surface_state.c diff --git a/src/mesa/drivers/dri/i965/Makefile b/src/mesa/drivers/dri/i965/Makefile index 2934414d99..4913c25f74 100644 --- a/src/mesa/drivers/dri/i965/Makefile +++ b/src/mesa/drivers/dri/i965/Makefile @@ -69,6 +69,7 @@ DRIVER_SOURCES = \ brw_vs_constval.c \ brw_vs_emit.c \ brw_vs_state.c \ + brw_vs_surface_state.c \ brw_vtbl.c \ brw_wm.c \ brw_wm_debug.c \ diff --git a/src/mesa/drivers/dri/i965/brw_curbe.c b/src/mesa/drivers/dri/i965/brw_curbe.c index 05a685af3d..7bd5021346 100644 --- a/src/mesa/drivers/dri/i965/brw_curbe.c +++ b/src/mesa/drivers/dri/i965/brw_curbe.c @@ -363,20 +363,6 @@ update_constant_buffer(struct brw_context *brw, } -/** Copy current vertex program's parameters into the constant buffer */ -static void -update_vertex_constant_buffer(struct brw_context *brw) -{ - struct brw_vertex_program *vp = - (struct brw_vertex_program *) brw->vertex_program;
