From 4617981ec72f7985941bee4b03c534d97ff96bc6 Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Thu, 5 Feb 2009 19:41:18 +0100 Subject: gallium: No longer allow CPU mapping surfaces directly. Instead, a new pipe_transfer object has to be created and mapped for transferring data between the CPU and a texture. This gives the driver more flexibility for textures in address spaces that aren't CPU accessible. This is a first pass; softpipe/xlib builds and runs glxgears, but it only shows a black window. Looks like something's off related to the Z buffer, so the depth test always fails. --- src/gallium/include/pipe/p_state.h | 28 ++++++++++++++++++++++++---- 1 file changed, 24 insertions(+), 4 deletions(-) (limited to 'src/gallium/include/pipe/p_state.h') diff --git a/src/gallium/include/pipe/p_state.h b/src/gallium/include/pipe/p_state.h index dd0dfac238d..34141ff2424 100644 --- a/src/gallium/include/pipe/p_state.h +++ b/src/gallium/include/pipe/p_state.h @@ -281,10 +281,6 @@ struct pipe_surface unsigned clear_value; /**< XXX may be temporary */ unsigned width; /**< logical width in pixels */ unsigned height; /**< logical height in pixels */ - struct pipe_format_block block; - unsigned nblocksx; /**< allocated width in blocks */ - unsigned nblocksy; /**< allocated height in blocks */ - unsigned stride; /**< stride in bytes between rows of blocks */ unsigned layout; /**< PIPE_SURFACE_LAYOUT_x */ unsigned offset; /**< offset from start of buffer, in bytes */ unsigned refcount; @@ -297,6 +293,30 @@ struct pipe_surface }; +/** + * Transfer object.
