* gallium: Create OGL state tracker wrappers for various CPU access operations.Thomas Hellstrom2009-04-171-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are two usage types of buffer CPU accesses: One where we try to use the buffer contents for multiple draw commands in a batch. (batch := sequence of commands that are flushed together), like incrementally adding bitmaps to a bitmap texture that is reallocated on flush. And one where we assume we can safely overwrite the old buffer contexts, like glTexSubImage. In this case we need to make sure all old drawing commands referencing the buffer are flushed before we map the buffer. This is easily forgotten. Add wrappers for the most common of these operations. The first type is prefixed with "st_no_flush" and the second type is prefixed with "st_cond_flush", where "cond" indicates that we attmpt to only flush if there is indeed unflushed draw commands referencing the buffer. Prefixed functions are screen::get_tex_transfer pipe_buffer_write pipe_buffer_read pipe_buffer_map Please use the wrappers whenever possible.

* mesa: merge the prog_src_register::NegateBase and NegateAbs fieldsBrian Paul2009-04-141-1/+1
| | | | | | There's really no need for two negation fields. This came from the GL_NV_fragment_program extension. The new, unified Negate bitfield applies after the absolute value step.
* st: remove comp_byte parameter to st_texture_create()Brian Paul2009-04-091-3/+2
| | | | We can determine if the texture is compressed by checking the format.
* gallium: consolidate bypass_vs and bypass_clipping flagsKeith Whitwell2009-03-131-1/+0
| | | | | | | | | The draw module provides a similar interface to the driver which is retained as various bits of hardware may be able to take on incremental parts of the vertex pipeline. However, there's no need to advertise all this complexity to the state tracker. There are basically two modes now - normal and passthrough/screen-coords.
* gallium: no need to keep a copy of shader tokens in state trackerKeith Whitwell2009-03-131-3/+1
| | | | | | | | Any driver who needs a copy of the shader tokens must organize to do so itself. This has been the case for a long time, but there was still defensive code in the state tracker, which is now removed. Any bugs resulting from this need to be fixed in the offending driver...

* gallium: Unify reference counting.Michel Dänzer2009-03-041-8/+8
| | | | | | | | | | | | | | The core reference counting code is centralized in p_refcnt.h. This has some consequences related to struct pipe_buffer: * The screen member of struct pipe_buffer must be initialized, or pipe_buffer_reference() will crash trying to destroy a buffer with reference count 0. u_simple_screen takes care of this, but I may have missed some of the drivers not using it. * Except for rare exceptions deep in winsys code, buffers must always be allocated via pipe_buffer_create() or via screen->*buffer_create() rather than via winsys->*buffer_create().
* mesa/st: support l8 as well as i8 in bitmap codeKeith Whitwell2009-02-241-1/+13
| | | | | Also don't send the partial program fragment down to hardware -- the program will never be used in that form.

* | gallium: No longer allow CPU mapping surfaces directly.Michel Dänzer2009-02-051-26/+26
|/ | | | | | | | | | 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.

| * gallium: avoid mapping same vertex buffer in subsequent framesKeith Whitwell2008-12-121-15/+45
| | | | | | | | | | | | | | | | | | | | | | Quite a few util modules were maintaining a single vertex buffer over multiple frames, and potentially reusing it in subsequent frames. Unfortunately that would force us into syncrhonous rendering as the buffer manager would be forced to wait for the previous rendering to complete prior to allowing the map. This resolves that issue, but requires the state tracker to issue a few new flush() calls at the end of each frame.

* | gallium: Add texture usage flags, special-case allocation of display targetsKeith Whitwell2008-05-021-2/+4
| | | | | | | | | | | | | | | | | | | | | | For many envirionments it's necessary to allocate display targets in a window-system friendly manner. Add facilities so that a driver can tell if a texture is likely to be used to generate a display surface and if use special allocation paths if necessary. Hook up softpipe to call into the winsys->surface_alloc_storage() routine in this case, though we probably want to change that interface slightly also.
