* gallium: remove TGSI_SAT_MINUS_PLUS_ONEMarek Olšák2015-05-201-2/+2
| | | | | | | | It's a remnant of some old NV extension. Unused. I also have a patch that removes predicates if anyone is interested. Reviewed-by: Roland Scheidegger <[email protected]>
* gallium: replace pipe_type enum with tgsi_return_type enumBrian Paul2014-09-221-4/+4
| | | | | | | | | | | The only place the enum pipe_type was used is for the TGSI sampler view return type. So make it a TGSI type. Note: it appears this part of TGSI isn't used by anyone so it may be removed in the future. v2: the new name is tgsi_return_type, not tgsi_type. This means we can drop the previously posted tgsi_type -> tgsi_opcode_type patch. Reviewed-by: Roland Scheidegger <[email protected]>

| | | | | | | | | | | | | | To further improve the optimization of source and destination indirect addressing we need the ability to store a reference to the declaration of the addressed operands. Since most of the fields in tgsi_src_register doesn't apply for an indirect addressing operand replace it with a separate tgsi_ind_register structure and so make room for extra information. v2: rename Declaration to ArrayID, put the ArrayID into () instead of [] Signed-off-by: Christian König <[email protected]>

* gallium/tgsi: Introduce the "LOCAL" register declaration modifier.Francisco Jerez2012-05-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | 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 resource write-back support.Francisco Jerez2012-05-111-0/+4
| | | | | Define a new STORE opcode with a role dual to the LOAD opcode, and add flags to specify that a shader resource is intended for writing.
* gallium/tgsi: Add support for raw resources.Francisco Jerez2012-05-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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: Define the TGSI_BUFFER texture target.Francisco Jerez2012-05-111-1/+1
| | | | | | This texture type was already referred to by the documentation but it was never defined. Define it as 0 to match the pipe_texture_target enumeration values.
* gallium/tgsi: Move interpolation info from tgsi_declaration to a separate token.Francisco Jerez2012-05-111-9/+48
| | | | | | Move Interpolate, Centroid and CylindricalWrap from tgsi_declaration to a separate token -- they only make sense for FS inputs and we need room for other flags in the top-level declaration token.
* gallium/tgsi: Split sampler views from shader resources.Francisco Jerez2012-05-111-24/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* tgsi: add support for texture offsets to the TGSI IR. (v2)Dave Airlie2011-09-021-1/+63
| | | | | | | | | | | | | 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.

Eg. there is now an Instruction.Label flag, etc. Drop destination modifiers and other functionality which cannot be generated by tgsi_ureg.c, which is now the primary way of creating shaders. Pull source modifiers into the source register token, drop the second negate flag. The source register token is now full - if we need to expand it, probably best to move all of the modifiers to a new token and have a single flag for it.

| | | | | | | | | | | | | Remove the need to have a pointer in this struct by just including the immediate data inline. Having a pointer in the struct introduces complications like needing to alloc/free the data pointed to, uncertainty about who owns the data, etc. There doesn't seem to be a need for it, and it is unlikely to make much difference plus or minus to performance. Added some asserts as we now will trip up on immediates with more than four elements. There were actually already quite a few such asserts, but the >4 case could be used in the future to specify indexable immediate ranges, such as lookup tables.
