From 1c181a7eff96816b5d72ea5daab5818eef0ebc60 Mon Sep 17 00:00:00 2001 From: Corbin Simpson Date: Sun, 15 Nov 2009 05:25:15 +0100 Subject: r300g: Begin separating HW TCL and SW TCL state and setup. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch removes draw_context entirely from the HW TCL path and cleans up a few other things along the way. Hopefully, nothing got broken. Thanks to Marek Olšák for testing, review, and pointing out my bugs. :3 --- src/gallium/drivers/r300/r300_context.c | 31 ++--- src/gallium/drivers/r300/r300_render.c | 4 - src/gallium/drivers/r300/r300_state.c | 8 +- src/gallium/drivers/r300/r300_state_derived.c | 192 +++++++++++++------------- src/gallium/drivers/r300/r300_vbo.c | 46 ------ src/gallium/drivers/r300/r300_vs.h | 3 - 6 files changed, 110 insertions(+), 174 deletions(-) diff --git a/src/gallium/drivers/r300/r300_context.c b/src/gallium/drivers/r300/r300_context.c index ae23329b83f..26db536248e 100644 --- a/src/gallium/drivers/r300/r300_context.c +++ b/src/gallium/drivers/r300/r300_context.c @@ -123,15 +123,24 @@ struct pipe_context* r300_create_context(struct pipe_screen* screen, r300->context.clear = r300_clear; - if (r300screen->caps->has_tcl) - { + if (r300screen->caps->has_tcl) { r300->context.draw_arrays = r300_draw_arrays; r300->context.draw_elements = r300_draw_elements; r300->context.draw_range_elements = r300_draw_range_elements; - } - else - { - assert(0); + } else { + r300->context.draw_arrays = r300_swtcl_draw_arrays; + r300->context.draw_elements = r300_draw_elements; + r300->context.draw_range_elements = r300_swtcl_draw_range_elements; + + /* Create a Draw.
