From: Keith Whitwell Date: Mon, 12 May 2008 14:20:38 +0000 (+0100) Subject: draw: add fetch-shade-emit path X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b5e5369da5fc50d63a6ece931fac44b555eb0314;p=mesa.git draw: add fetch-shade-emit path Enable with TEST_FSE=t. Performs fetch from API-provided vertex buffers, transformation with one of three (two working) hard-coded shaders, and final emit to hardware vertices all in a single pass. Currently only really useful for profiling in conjunction with SP_NO_RAST=t. --- diff --git a/src/gallium/auxiliary/draw/Makefile b/src/gallium/auxiliary/draw/Makefile index da7eded21f6..68e7744cc5a 100644 --- a/src/gallium/auxiliary/draw/Makefile +++ b/src/gallium/auxiliary/draw/Makefile @@ -26,6 +26,7 @@ C_SOURCES = \ draw_pt_emit.c \ draw_pt_fetch.c \ draw_pt_fetch_emit.c \ + draw_pt_fetch_shade_emit.c \ draw_pt_fetch_shade_pipeline.c \ draw_pt_post_vs.c \ draw_pt_varray.c \ diff --git a/src/gallium/auxiliary/draw/draw_private.h b/src/gallium/auxiliary/draw/draw_private.h index e036d498b87..cbe64cd2903 100644 --- a/src/gallium/auxiliary/draw/draw_private.h +++ b/src/gallium/auxiliary/draw/draw_private.h @@ -124,12 +124,14 @@ struct draw_context struct { struct { struct draw_pt_middle_end *fetch_emit;
