From d7d4a1955b4f1fcafb5efab06a9f982fccefa19b Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 21 Feb 2012 08:26:30 -0700 Subject: [PATCH] st/mesa: initialize the MaxViewport, MaxRenderbufferSize constants Use the max 2D/rect texture size as the limit. If that's not true for some devices we'll need new PIPE_CAP_ queries. --- src/mesa/state_tracker/st_extensions.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/src/mesa/state_tracker/st_extensions.c b/src/mesa/state_tracker/st_extensions.c index fb36a6809c0..33bc6ed729b 100644 --- a/src/mesa/state_tracker/st_extensions.c +++ b/src/mesa/state_tracker/st_extensions.c @@ -108,6 +108,14 @@ void st_init_limits(struct st_context *st) c->MaxTextureUnits = _min(c->MaxTextureImageUnits, c->MaxTextureCoordUnits); + /* Define max viewport size and max renderbuffer size in terms of + * max texture size (note: max tex RECT size = max tex 2D size). + * If this isn't true for some hardware we'll need new PIPE_CAP_ queries. + */ + c->MaxViewportWidth = + c->MaxViewportHeight = + c->MaxRenderbufferSize = c->MaxTextureRectSize; + c->MaxDrawBuffers = _clamp(screen->get_param(screen, PIPE_CAP_MAX_RENDER_TARGETS), 1, MAX_DRAW_BUFFERS); -- 2.30.2
