* gallium: PIPE_COMPUTE_CAP_IR_TARGET - allow drivers to specify a processor v2Tom Stellard2013-04-051-4/+4
| | | | | | | | | | | | This target string now contains four values instead of three. The old processor field (which was really being interpreted as arch) has been split into two fields: processor and arch. This allows drivers to pass a more a more detailed description of the hardware to compiler frontends. v2: - Adapt to libclc changes Reviewed-by: Francisco Jerez <[email protected]>

* gallium: add TGSI_SEMANTIC_TEXCOORD,PCOORD v3Christoph Bumiller2013-03-203-0/+42
| | | | | | | | | | | | | | | This makes it possible to identify gl_TexCoord and gl_PointCoord for drivers where sprite coordinate replacement is restricted. The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings should be hidden behind the GENERIC semantic or not. With this patch only nvc0 and nv30 will request that they be used. v2: introduce a CAP so other drivers don't have to bother with the new semantic v3: adapt to introduction gl_varying_slot enum

* llvmpipe: bump glsl version to 140Roland Scheidegger2013-03-021-11/+4
| | | | | | | | | | | | | texel offsets should have been the last missing feature for 130, and in fact 140 as well (last there were texture buffers). In any case we still don't do OpenGL 3.0 (missing MSAA which will be difficult, plus EXT_packed_float, ARB_depth_buffer_float and EXT_framebuffer_sRGB). v2: bump to 140 instead - we have everything except we crash when not writing to gl_Position (but softpipe crashes as well) so let's just say this is a bug instead. Also (by Dave Airlie's suggestion) update llvm-todo.txt. Reviewed-by: Jose Fonseca <[email protected]>
* gallium/docs: improve text about resources a bit.Roland Scheidegger2013-02-221-29/+33
| | | | | | | | | | | This clarifies some things and gets rid of some old stuff. The most significant one is probably that buffers cannot have formats (nearly all drivers completely ignored format and used width0 as byte size already in any case). There seems to be no use case for "structured" buffers. (Note while d3d11 has new Structured Buffers, these still aren't associated with a format, rather a byte stride, which we can't do yet either way.) Reviewed-by: Jose Fonseca <[email protected]>
* gallivm/tgsi: fix src modifier fetching with non-float types.Roland Scheidegger2013-02-161-0/+15
| | | | | | | | | | | | | | Need to take the type into account. Also, if we want to allow mov's with modifiers we need to pick a type (assume float). v2: don't allow all modifiers on all type, in particular don't allow absolute on non-float types and don't allow negate on unsigned. Also treat UADD as signed (despite the name) since it is used for handling both signed and unsigned integer arguments and otherwise modifiers don't work. Also add tgsi docs clarifying this.

* gallium: fix tgsi SAMPLE_L opcode to use separate source for explicit lodRoland Scheidegger2013-02-121-4/+3
| | | | | | | | | | | | | | | | | | | | | It looks like using coord.w as explicit lod value is a mistake, most likely because some dx10 docs had it specified that way. Seems this was changed though: http://msdn.microsoft.com/en-us/library/windows/desktop/hh447229%28v=vs.85%29.aspx - let's just hope it doesn't depend on runtime build version or something. Not only would this need translation (so go against the stated goal these opcodes should be close to dx10 semantics) but it would prevent usage of this opcode with cube arrays, which is apparently possible: http://msdn.microsoft.com/en-us/library/windows/desktop/bb509699%28v=vs.85%29.aspx (Note not only does this show cube arrays using explicit lod, but also the confusion with this opcode: it lists an explicit lod parameter value, but then states last component of location is used as lod). (For "true" hw drivers, only nv50 had code to handle it, and it appears the code was already right for the new semantics, though fix up the seemingly wrong c/d arguments while there.) v2: fix comment, separate out other changes.

* gallivm: fix up size queries for dx10 sviewinfo opcodeRoland Scheidegger2013-02-081-1/+1
| | | | | | | | | | | | | | | Need to calculate the number of mip levels (if it would be worthwile could store it in dynamic state). While here, the query code also used chan 2 for the lod value. This worked with mesa state tracker but it seems safer to use chan 0. Still passes piglit textureSize (with some handwaving), though the non-GL parts are (largely) untested. v2: clarify and expect the sviewinfo opcode to return ints, not floats, just like the OpenGL textureSize (dx10 supports dst modifiers with resinfo). Also simplify some code. Reviewed-by: Jose Fonseca <[email protected]>
* gallium: add SQRT shader opcodeBrian Paul2013-02-041-0/+9
| | | | | | | | | | | | | | | | | | The glsl-to-tgsi translater will emit SQRT to implement GLSL's sqrt() and distance() functions if the PIPE_SHADER_CAP_TGSI_SQRT_SUPPORTED query says it's supported by the driver. Otherwise, sqrt(x) is implemented with x*rsq(x). The problem with this is sqrt(0) must be handled specially because rsq(0) might be Inf/NaN/undefined (and then 0*rsq(0) is Inf/Nan/undefined). In the glsl-to-tgsi code we use an extra CMP to check if x is zero and then replace the result of x*rsq(x) with zero. In the end, this makes sqrt() generate much more reasonable code for drivers that can do square roots. Note that many of piglit's generated shader tests use the GLSL distance() function.

* | gallium/compute: Drop TGSI dependency.Francisco Jerez2012-05-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Add a shader cap for specifying the preferred shader representation. Right now the only supported value is TGSI, other enum values will be added as they are needed. This is mainly to accommodate AMD's LLVM compiler back-end by letting it bypass the TGSI representation for compute programs. Other drivers will keep using the common TGSI instruction set.

* | gallium/tgsi: Introduce the "LOCAL" register declaration modifier.Francisco Jerez2012-05-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Jerez2012-05-111-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Jerez2012-05-111-40/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
