From 8acaf862dfeac62550514b0e46f5aa6212b08992 Mon Sep 17 00:00:00 2001 From: Christoph Bumiller Date: Fri, 15 Mar 2013 22:11:31 +0100 Subject: gallium: add TGSI_SEMANTIC_TEXCOORD,PCOORD v3 This makes it possible to identify gl_TexCoord and gl_PointCoord for drivers where sprite coordinate replacement is restricted. The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings should be hidden behind the GENERIC semantic or not. With this patch only nvc0 and nv30 will request that they be used. v2: introduce a CAP so other drivers don't have to bother with the new semantic v3: adapt to introduction gl_varying_slot enum --- src/mesa/state_tracker/st_context.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/mesa/state_tracker/st_context.c') diff --git a/src/mesa/state_tracker/st_context.c b/src/mesa/state_tracker/st_context.c index f9a584ba0ac..e2d074d14a4 100644 --- a/src/mesa/state_tracker/st_context.c +++ b/src/mesa/state_tracker/st_context.c @@ -183,6 +183,9 @@ st_create_context_priv( struct gl_context *ctx, struct pipe_context *pipe, screen->get_param(screen, PIPE_CAP_SHADER_STENCIL_EXPORT); st->has_shader_model3 = screen->get_param(screen, PIPE_CAP_SM3); + st->needs_texcoord_semantic = + screen->get_param(screen, PIPE_CAP_TGSI_TEXCOORD); + /* GL limits and extensions */ st_init_limits(st); st_init_extensions(st); -- cgit v1.2.3
