From ffb732d8bd51f0a40379590a6485de2a56a2a306 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sun, 14 Nov 2010 18:57:14 +0100 Subject: r300g: fix rendering with no vertex elements Fixes glsl-vs-point-size, although I meant to fix glsl-novertexdata. Since swrast fails glsl-novertexdata too, I guess it's a core issue. --- src/gallium/drivers/r300/r300_context.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'src/gallium/drivers/r300/r300_context.c') diff --git a/src/gallium/drivers/r300/r300_context.c b/src/gallium/drivers/r300/r300_context.c index fb099e2a7d..e8c09b214a 100644 --- a/src/gallium/drivers/r300/r300_context.c +++ b/src/gallium/drivers/r300/r300_context.c @@ -79,6 +79,9 @@ static void r300_release_referenced_objects(struct r300_context *r300) NULL); } + /* The dummy VBO. */ + pipe_resource_reference(&r300->dummy_vb, NULL); + /* The SWTCL VBO. */ pipe_resource_reference(&r300->vbo, NULL); @@ -488,6 +491,7 @@ struct pipe_context* r300_create_context(struct pipe_screen* screen, rtempl.target = PIPE_TEXTURE_2D; rtempl.format = PIPE_FORMAT_I8_UNORM; rtempl.bind = PIPE_BIND_SAMPLER_VIEW; + rtempl.usage = PIPE_USAGE_IMMUTABLE; rtempl.width0 = 1; rtempl.height0 = 1; rtempl.depth0 = 1; @@ -501,6 +505,19 @@ struct pipe_context* r300_create_context(struct pipe_screen* screen, pipe_resource_reference(&tex, NULL); } + { + struct pipe_resource vb = {}; + vb.target = PIPE_BUFFER; + vb.format = PIPE_FORMAT_R8_UNORM; + vb.bind = PIPE_BIND_VERTEX_BUFFER; + vb.usage = PIPE_USAGE_IMMUTABLE; + vb.width0 = sizeof(float) * 16; + vb.height0 = 1; + vb.depth0 = 1; + + r300->dummy_vb = screen->resource_create(screen, &vb); + } + return &r300->context; fail: -- cgit v1.2.3
