* gallivm,llvmpipe: handle TXF (texelFetch) instruction, including offsetsRoland Scheidegger2012-11-271-0/+1
| | | | | | | | | | | | | This also adds some code to handle per-quad lods for more than 4-wide fetches, because otherwise I'd have to integrate the texelFetch function into the splitting stuff... (but it is not used yet outside texelFetch). passes piglit fs-texelFetch-2D, fails fs-texelFetchOffset-2D due to I believe a test error (results are undefined for out-of-bounds fetches, we return whatever is at offset 0, whereas the test expects [0,0,0,1]). Texel offsets are only handled by texelFetch for now, though the interface can handle it for everything. Reviewed-by: José Fonseca <[email protected]>

| | | | | | | | | | | | | This adds support to the softpipe texture sampler and tgsi exec. In order to handle the extra input to the texture sampling, I've had to expand the interfaces to take a c1 value for storing the texture compare value for the TEX2 case. v1.1: add comments (Brian) Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
* gallium: add defines/shader opcode for texture cube map arrayDave Airlie2012-11-093-2/+9
| | | | | | | | | | | | | | | | This just adds the texture target and capability along with 3 new opcodes required to support this extension. As this extension requires some texture opcodes with samp + 5 args, we need to use another src register, this is only required for TEX, TXL and TXB opcodes to implement this spec. TEX2 is required for shadow cube map arrays TXL2 is required for cube map array sampler + explicit lod TXB2 is required for cube map array sampler + lod bias Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
* mesa: bump MAX_VARYING to 32Marek Olšák2012-10-291-1/+1
| | | | | | | | | | | | | | | | | We're starting to get apps utilizing more than 16 varyings and most current hardware supports 32 anyway. Tested with r600g. swrast, softpipe and llvmpipe still advertise 16 varyings. This fixes a WebGL crash after launching this demo: https://developer.mozilla.org/en-US/demos/detail/falling-cubes Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=54402 NOTE: This is a candidate for the stable branches.

| | | | | | | | | | The only allowed instructions are TXQ_LZ and TXF. TXQ_LZ is like TXQ, but without the LOD parameter (which is always zero with MSAA textures) The 3rd or the 4th texcoord component in TXF should contain the sample index for a 2D_MSAA or 2D_ARRAY_MSAA texture, respectively.

* gallium/tgsi: Introduce the "LOCAL" register declaration modifier.Francisco Jerez2012-05-113-26/+46
| | | | | | | | | | | | | | | | | | | | | | | This change will be useful to implement function parameter passing on top of TGSI. As we don't have a proper stack, a register-based calling convention will be used instead, which isn't necessarily a bad thing given that GPUs often have plenty of registers to spare. Using the same register space for local temporaries and inter-procedural communication caused some inefficiencies, because in some cases the register allocator would lose the freedom to merge temporary values together into the same physical register, leading to suboptimal register (and sometimes, as a side effect, instruction) usage. The LOCAL declaration modifier specifies that the value isn't intended for parameter passing and as a result the compiler doesn't have to give any guarantees of it being preserved across function boundaries. Ignoring the LOCAL flag doesn't change the semantics of a valid program in any way, because local variables are just supposed to get a more relaxed treatment. IOW, this should be a backwards-compatible change.

* gallium/tgsi: Add support for raw resources.Francisco Jerez2012-05-113-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | Normal resource access (e.g. the LOAD TGSI opcode) is supposed to perform a series of conversions to turn the texture data as it's found in memory into the target data type. In compute programs it's often the case that we only want to access the raw bits as they're stored in some buffer object, and any kind of channel conversion and scaling is harmful or inefficient, especially in implementations that lack proper hardware support to take care of it -- in those cases the conversion has to be implemented in software and it's likely to result in a performance hit even if the pipe_buffer and declaration data types are set up in a way that would just pass the data through. Add a declaration flag that marks a resource as typeless. No channel conversion will be performed in that case, and the X coordinate of the address vector will be interpreted in byte units instead of elements for obvious reasons. This is similar to D3D11's ByteAddressBuffer, and will be used to implement OpenCL's constant arguments. The remaining four compute memory spaces can also be understood as raw resources.

* gallium/tgsi: Split sampler views from shader resources.Francisco Jerez2012-05-1112-107/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit splits the current concept of resource into "sampler views" and "shader resources": "Sampler views" are textures or buffers that are bound to a given shader stage and can be read from in conjunction with a sampler object. They are analogous to OpenGL texture objects or Direct3D SRVs. "Shader resources" are textures or buffers that can be read and written from a shader. There's no support for floating point coordinates, address wrap modes or filtering, and, unlike sampler views, shader resources are global for the whole graphics pipeline. They are analogous to OpenGL image objects (as in ARB_shader_image_load_store) or Direct3D UAVs. Most hardware is likely to implement shader resources and sampler views as separate objects, so, having the distinction at the API level simplifies things slightly for the driver. This patch introduces the SVIEW register file with a declaration token and syntax analogous to the already existing RES register file. After this change, the SAMPLE_* opcodes no longer accept a resource as input, but rather a SVIEW object. To preserve the functionality of reading from a sampler view with integer coordinates, the SAMPLE_I(_MS) opcodes are introduced which are similar to LOAD(_MS) but take a SVIEW register instead of a RES register as argument.
