* st/mesa: do vertex and fragment color clamping in shadersMarek Olšák2012-01-251-1/+3
| | | | | | | | | | | | | | For ARB_color_buffer_float. Most hardware can't do it and st/mesa is the perfect place for a fallback. The exceptions are: - r500 (vertex clamp only) - nv50 (both) - nvc0 (both) - softpipe (both) We also have to take into account that r300 can do CLAMPED vertex colors only, while r600 can do UNCLAMPED vertex colors only. The difference can be expressed with the two new CAPs.

* softpipe: allow softpipe to set shader params depending on runtime llvm (v3)Dave Airlie2012-01-113-9/+18
| | | | | | | | | | | | | If draw isn't using llvm we can support vertex texture and integers, These will be fixed up later, but for now allow this check to happen at run-time. v2: since 3e22c7a25321554a32fa6254485912fd53deff3a we can ask draw for a non-llvm context. Just track if ask and set the vars accordingly. This probably isn't perfect but should cover the cases we care about. v3: use debug option, restructure to store in screen, as suggested by Jakob.

* draw/softpipe: EXT_transform_feedback support (v2)Dave Airlie2012-01-109-160/+80
| | | | | | | | | | | This replaces the current code with an implementation compatible with the new gallium interface. I've left some of the remains of the interface intact so llvmpipe keeps building correctly, and I'll take a look at fixing llvmpipe up later. v2: fixup as per Brian's review Signed-off-by: Dave Airlie <[email protected]>
* gallium: introduce GLSL based interpolation rules. (v2)Dave Airlie2012-01-102-2/+9
| | | | | | | | | | | | This introduces an unspecified interpolation paramter that is only allowed for color semantics, so a specified GLSL interpolation will override the ShadeModel specified interpolation, but not vice-versa. This fixes a lot of the interpolation tests in piglit. v2: rename from unspecified to color Signed-off-by: Dave Airlie <[email protected]>

| | | | | | | This patch remove the 32bits limitation. As a side effect, it bring the support for the GL_ARB_depth_buffer_float extension. No regression have been found on piglit, and all tests for GL_ARB_depth_buffer_float pass successfully. Signed-off-by: Dave Airlie <[email protected]>
* softpipe: try and use back color for a slot if color fails.Dave Airlie2011-12-221-0/+5
| | | | | | | | | | | | | | In the case where a front and back output are specified, the draw code will copy the back output into the front color slot and everything is happy. However if no front is specified then the draw code will do a bad copy (separate patch), but also the frag shader won't pick up the color as there there is no write to COLOR from the vertex shader just BCOLOR. This patch fixes that problem so if it can't find a vertex shader output for the front color slot, it will go and lookup and use one for the back color slot.

* gallium: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-153-12/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Namely: - EXT_transform_feedback - ARB_transform_feedback2 - ARB_transform_feedback_instanced The old interface was not useful for OpenGL and had to be reworked. This interface was originally designed for OpenGL, but additional changes have been made in order to make st/d3d1x support easier. The most notable change is the stream-out info must be linked with a vertex or geometry shader and cannot be set independently. This is due to limitations of existing hardware (special shader instructions must be used to write into stream-out buffers), and it's also how OpenGL works (stream outputs must be specified prior to linking shaders). Other than that, each stream output buffer has a "view" into it that internally maintains the number of bytes which have been written into it. (one buffer can be bound in several different transform feedback objects in OpenGL, so we must be able to have several views around) The set_stream_output_targets function contains a parameter saying whether new data should be appended or not. Also, the view can optionally be used to provide the vertex count for draw_vbo. Note that the count is supposed to be stored in device memory and the CPU never gets to know its value. OpenGL way | Gallium way ------------------------------------ BeginTF = set_so_targets(append_bitmask = 0) PauseTF = set_so_targets(num_targets = 0) ResumeTF = set_so_targets(append_bitmask = ~0) EndTF = set_so_targets(num_targets = 0) DrawTF = use pipe_draw_info::count_from_stream_output v2: * removed the reset_stream_output_targets function * added a parameter append_bitmask to set_stream_output_targets, each bit specifies whether new data should be appended to each buffer or not. v3: * added PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME for ARB_tfb2, note that the draw-auto subset is always required (for d3d10), only the pause/resume functionality is limited if the CAP is not advertised v4: * update gallium/docs v5: * compactified struct pipe_stream_output_info, updated dump/trace

* gallium: separate out floating-point CAPs into its own enumMarek Olšák2011-11-221-7/+7
| | | | | | | | | | | | | | | The motivation behind this is to add some self-documentation in the code about how each CAP can be used. The idea is: - enum pipe_cap is only valid in get_param - enum pipe_capf is only valid in get_paramf Which CAPs are floating-point have been determined based on how everybody except svga implemented the functions. svga have been modified to match all the other drivers. Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.
* gallium: remove PIPE_CAP_GLSL and enable GLSL unconditionallyMarek Olšák2011-11-221-2/+0

* softpipe: fix Z interpolation invariance bugBrian Paul2011-10-041-1/+10
| | | | | | | | | We want quad/pixel Z values to be interpolated exactly the same for multi-pass algorithms. Because of how the optimized Z-test code is written, we can't cull the first quad in a run even if it's totally killed. See the comment for more info. NOTE: This is a candidate for the 7.11 branch.

Notes: 1. the value is opaque. 2. only when the value is used should it be interpretered according to the surface format it is going to be used with. 3. float clears on integer buffers and vice-versa are undefined. v2: fixed up vega and graw, dropped hunks that shouldn't have been in patch.

* softpipe: fix blending for luminance/intensity surfacesBrian Paul2011-09-151-65/+96
| | | | | | | | | | | | | | If we're drawing to a luminance, luminance/alpha or intensity surface we have to adjust (rebase) the fragment/quad colors before writing them to the tile cache. The tile cache always stores RGBA colors but if we're caching a L/A surface (for example) we need to be sure that R=G=B so that subsequent reads from the surface cache appear to return L/A We previously had a special case for RGB (no alpha) surfaces. This change generalizes that for the other base formats. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=40408, but sRGB formats are still failing. That'll be addressed in a later patch.
