* gallium: move gen-mipmap global/static vars into st_contextBrian2008-02-122-28/+22
| | | | This fixes potential problems with multi-context programs.

|
* gallium: clean-up, simplification of mipmapped texturesBrian2008-02-124-64/+71
| | | | | | | | Remove pipe_texture->first_level (always implicitly zero). This means there's never any unused mipmap levels at the top. In the state tracker, we no longer re-layout mipmapped textures if the MinLod/MaxLod texture parameters change. It's up to the driver to obey the pipe_sampler->min/max_lod clamps.
* gallium: take pitch/stride into account in mipmap generationBrian2008-02-111-1/+2

* gallium: comments about mipmap genBrian2008-02-111-0/+5
|
* gallium: implement software fallback for mipmap generationBrian2008-02-111-8/+60
| | | | | This is used when we can't render to the surface type of the texture (such as luminance/alpha).
* gallium: strip borders from textures passed to st_TexImage.Brian2008-02-111-3/+50
| | | | | Manipulate the unpack params to skip the border. Gallium drivers won't support texture borders.
* gallium: use _mesa_tex_target_to_face()Brian2008-02-111-21/+1
|
* gallium: include st_cb_drawpixels.hBrian2008-02-081-0/+1
|
* gallium: initial implemenation of auto mipmap generation in state trackerBrian2008-02-084-7/+414
| | | | | | Use hardware rendering to compute/render mipmap levels. The fallback path (which will be used for non-renderable texture formats) isn't working yet.

* gallium: change pipe->texture_create() to operate like the CSO functionsBrian2008-02-061-18/+13
| | | | Now, pass in a template object and return a new object.

* gallium: add bitmap/drawpixels texcoord bias supportBrian2008-02-063-2/+10
| | | | | | | The state tracker will call pipe->get_paramf(PIPE_CAP_BITMAP_TEXCOORD_BIAS) to get a bias factor for adjusting the texcoords used in bitmap/drawpixels. This allows us to compensate for small differences in rasterization from one device to another.

* Fix problem in mapping vertex program outputs (found with "spring" game engine)Brian2008-01-311-4/+6
| | | | | If the vertex program writes to an output that's not consumed by the fragment program, map the vp output to an unused slot.
* gallium: don't rely on assert(0) for error handling - may be disabledKeith Whitwell2008-01-291-0/+2

* gallium: check if surface has defined status in check_clear_depth_with_quad()Brian2008-01-281-1/+3
| | | | This was part of Keith's patch from Friday.
* gallium: minor cleanups to pipe interfaceKeith Whitwell2008-01-261-6/+29
| | | | | - Remove put/get tile, just have users call put_tile_raw, etc directly. - Remove surface_data call, just map it locally.

* gallium: replace prim pipeline begin/end() functions with flush()Brian2008-01-252-29/+6
| | | | | | | | | | | | | This is basically half of Keith's draw/flush patch. The stage->point/line/tri() functions are now self-validating, the validator functions are installed by the flush() function. There were excessive calls to validate_pipeline(), however. This was caused by draw_prim_queue_flush() keeping a local 'first' variable that always pointed to the validate functions. Replaced 'first' with 'draw->pipeline.first'. Performance in gears is up just slightly with this patch.
* gallium: rename pipe_buffer_handle to pipe_buffer, rework pipebuffer/ codeKeith Whitwell2008-01-256-18/+22
| | | | | | | | | | | Provide an actual definition of the pipe_buffer struct, containing the parameters used to create the buffer, and its refcount. Shift refcounting buffers out of the winsys interface, similar to surfaces & textures. Rework pipebuffer/ to reflect the fact these changes, and also Michel's reworking of the buffer interface.
* gallium: Simplify winsys buffer interface.Michel Dänzer2008-01-255-89/+86
| | | | | | The properties of a buffer represented by struct pipe_buffer_handle are now basically constant over its lifetime. The state tracker gets to deal with any more complex buffer semantics it may need to provide.

* gallium: overhaul usage of vertex_info in draw module.Brian2008-01-231-0/+4
| | | | | | | | Remove all dependencies on vertex_info, except for draw_vbuf. Drawing stages now strictly operate on post-transformed vertices and don't know anything about hw vertices. Use vertex program output info for two-side/flat/etc stages. Temporarily disable vbuf module in softpipe driver.

* Back-port miscellaneous fixes from internal branch (mostly portability fixes).José Fonseca2008-01-172-0/+5
| | | | | | These are changes that are in our internal branch, but somehow were skipped so far. It was done using visual comparison of the branches -- it is likely that changes are being carried on the wrong way
