* 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: disable stream output in drivers that support itMarek Olšák2011-12-153-2/+9

* 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
| | | | | Only i965g does not enable GLSL, but that driver has been unmaintained and bitrotting for quite a while anyway.
* Remove tgsi_sse2.José Fonseca2011-11-088-266/+1
| | | | tgsi_exec is simple. llvm is fast. tgsi_sse2 ends up being neither.

* 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.
* softpipe: add check for DO_PSTIPPLE_IN_HELPER_MODULEBrian Paul2011-10-041-0/+2
| | | | | We only want to generate the fragment shader variant that does stippling if DO_PSTIPPLE_IN_HELPER_MODULE is being used.
* gallium: add PIPE_CAP_CONDITIONAL_RENDERMarek Olšák2011-09-301-0/+2
| | | | | | | We were checking whether render_condition is set. That was not reliable, because it's always set with trace and noop regardless of driver support. Reviewed-by: Brian Paul <[email protected]>
* gallium: add and use PIPE_SHADER_CAP_MAX_TEXTURE_SAMPLERSMarek Olšák2011-09-301-10/+11
| | | | | | | | | This removes: - PIPE_CAP_MAX_TEXTURE_IMAGE_UNITS - PIPE_CAP_MAX_VERTEX_TEXTURE_UNITS in favor of the that new per-shader cap. Reviewed-by: Brian Paul <[email protected]>
* gallium: remove PIPE_CAP_TEXTURE_MIRROR_REPEATMarek Olšák2011-09-301-2/+0
| | | | | | | | | | All drivers support it (well, except Cell). The boolean option is going away from core Mesa too. This is a follow-up to Ian Romanick's patch "mesa: Remove ARB_texture_mirrored_repeat extension enable flag". Reviewed-by: Brian Paul <[email protected]>
* gallium: move border color to be a color unionDave Airlie2011-09-271-4/+4

* gallium: move clear paths from rgba to a pointer to a color union (v2)Dave Airlie2011-09-182-4/+6
| | | | | | | | | | | | | | | This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values. 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: use pipe_get_tile_rgba_format()Brian Paul2011-09-161-5/+6
| | | | | | | | | | | Pass an explicit surface format as we do with pipe_put_tile_rgba_format(). This fixes the piglit fbo-srgb-blit test. With GL_EXT_framebuffer_sRGB we override the resource's format with an explicit format (linear vs. sRGB). We need to do so both when getting and putting tiles.

* 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.
* softpipe: implement blend color clampingBrian Paul2011-09-143-29/+117
| | | | | | | | | Per the GL spec, clamp incoming colors prior to blending depending on whether the destination buffer stores normalized (non-float) values. Note that the constant blend color needs to be clamped too (we always get the unclamped color from Mesa). Fixes https://bugs.freedesktop.org/show_bug.cgi?id=40412
* gallium: add PIPE_CAP_MAX_TEXTURE_ARRAY_LAYERSMarek Olšák2011-09-101-2/+2

* tgsi: add support for texture offsets to the TGSI IR. (v2)Dave Airlie2011-09-021-5/+12
| | | | | | | | | | | | | This adds tokens for texture offsets, to store 4 * swizzled vec 3 for use in TXF and other opcodes. It also contains TGSI exec changes for softpipe to use this code, along with GLSL->TGSI support for TXF. v2: add some more comments, add back padding I removed.

| * softpipe: use the polygon stipple utility moduleBrian Paul2011-07-219-14/+131
| | | | | | | | | | | | | | | | | | | | This is an alternative to the draw module's polygon stipple stage. The softpipe implementation here is just a test. The advantange of using the new polygon stipple utility module (with other drivers) is we can avoid software vertex processing in the draw module and get much better performance. Polygon stipple doesn't require special vertex processing like the other draw module stage.
