* gallium: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-153-38/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Olšák2011-11-222-12/+20
| | | | | | | | | | | | | | | 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 Olšák2011-11-221-1/+0

* gallium: add PIPE_BIND_BLENDABLE flagChristoph Bumiller2011-10-151-4/+5
| | | | | | | | | This is required for an accurate implementation of d3d1x's CheckFormatSupport query. It also seems generally useful for state trackers, which could choose alternative rendering paths or formats if blending would come at a significant performance loss.
* gallium: rename ZS stencil type to UINT (v2)Dave Airlie2011-10-111-7/+7

* gallium: add initial pure integer support (v2)Dave Airlie2011-10-081-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | This add support for unsigned/signed integer types via adding a 'pure' bit in the format description table. It adds 4 new u_format get/put hooks, for get/put uint and get/put sint so that accessors can get native access to the integer bits. This is used to avoid precision loss via float converting paths. It doesn't add any float fetchers for these types at the moment, GL doesn't require float fetching from these types and I expect we'll introduce a lot of hidden bugs if we start allowing such conversions without an API mandating it. It adds all formats from EXT_texture_integer and EXT_texture_rg. 0 regressions on llvmpipe here with this. (there is some more follow on code in my gallium-int-work branch, bringing softpipe and mesa to a pretty integer clean state) v2: fixup python generator to get signed->unsigned and unsigned->signed fetches working.

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.
