| | | | | | | | This reduces CPU overhead when updating constants.
| * gallium: add void *user_buffer in pipe_index_bufferMarek Olšák2012-04-301-3/+6
| | | | | | | | | | | | | | Adapted drivers: i915, llvmpipe, r300, r600, radeonsi, softpipe. User index buffers have been disabled in nv30, nv50, nvc0 and svga to keep things working.

| * gallium: add void *user_buffer in pipe_vertex_bufferMarek Olšák2012-04-301-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | This reduces CPU overhead in st_draw_vbo and removes a lot of unnecessary code in that function which was required only to comply with the gallium interface, but wasn't any useful really. Adapted drivers: i915, llvmpipe, r300, softpipe. No changes required in: r600, radeonsi. User vertex buffers have been disabled in nv30, nv50, nvc0 and svga to keep things working.

| * gallium: add PIPE_CAP_CONSTANT_BUFFER_OFFSET_ALIGNMENTMarek Olšák2012-04-301-0/+2
| | | | | | | | | | | | | | | | This is required for any serious constant buffer support. Constant buffer offsets on ATI and NVIDIA DX10 and DX11 GPUs must be a multiple of 256. In OpenGL, this can be queried via GL_UNIFORM_BUFFER_OFFSET_ALIGNMENT.

* softpipe: set max cube texture size to 4Kx4KBrian Paul2012-03-202-1/+2
| | | | | | | | | | The max size was 16Kx16K so a 4 byte/pixel, six-sided cube would require 6 GBytes of memory. If mipmapped, 8 GB. Reduce the max size to 4K to make the total size more reasonable.

| | | | | | | | v2: handle the cap in r300 and r600 as well Additional info for r600g: The env var R600_GLSL130=1 enables GLSL 1.3. Along with R600_STREAMOUT=1, it enables full GL 3.
* 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.

| | | | | | | | | | | 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.

* 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
