From a016043386045d7cc35d70e42d963704fcae3731 Mon Sep 17 00:00:00 2001 From: Zack Rusin Date: Tue, 15 Sep 2009 11:01:21 -0400 Subject: st/xorg: fixing copies and composite shaders copies were busted when src == dst. also the composite shaders were incorrectly using the fragments instead of the texture coordinate. --- src/gallium/state_trackers/xorg/xorg_composite.c | 65 +++++++++++++++++++++++- src/gallium/state_trackers/xorg/xorg_exa.c | 20 +++++--- src/gallium/state_trackers/xorg/xorg_exa_tgsi.c | 4 +- 3 files changed, 78 insertions(+), 11 deletions(-) (limited to 'src/gallium') diff --git a/src/gallium/state_trackers/xorg/xorg_composite.c b/src/gallium/state_trackers/xorg/xorg_composite.c index edb7620f124..66ca4cb5905 100644 --- a/src/gallium/state_trackers/xorg/xorg_composite.c +++ b/src/gallium/state_trackers/xorg/xorg_composite.c @@ -952,6 +952,61 @@ static void renderer_copy_texture(struct exa_context *exa, pipe_surface_reference(&dst_surf, NULL);
