* gallium/tgsi: Move interpolation info from tgsi_declaration to a separate token.Francisco Jerez2012-05-111-1/+1
| | | | | | 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 Jerez2012-05-111-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 TGSI_TEXTURE_SHADOWCUBEMAPDave Airlie2012-01-111-0/+2
| | | | | | | | This adds support for shadow cubemap texture sampling instructions. This is required for GL 3.0. Signed-off-by: Dave Airlie <[email protected]>
* tgsi: add ISSG supportDave Airlie2012-01-111-0/+14

* tgsi/softpipe: add VertexID support.Dave Airlie2012-01-111-4/+10
| | | | | | | | | | This required changing the system value semantics, so we stored a system value per vertex, instance id is the only other system value we currently support, so I span it across the channels. This passes the 3 vertexid-* piglit tests + lots of instanceid tests. Signed-off-by: Dave Airlie <[email protected]>
* gallium: introduce GLSL based interpolation rules. (v2)Dave Airlie2012-01-101-0/+4
| | | | | | | | | | | | 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. This fixes a lot of the interpolation tests in piglit. v2: rename from unspecified to color Signed-off-by: Dave Airlie <[email protected]>

* tgsi/softpipe: disable FAST_MATHDave Airlie2012-01-031-1/+1
| | | | | | | In the interest of softpipe preferring correctness over speed and passing more piglit tests, set this to off by default. For speed you really want llvmpipe. Signed-off-by: Dave Airlie <[email protected]>
* softpipe: reorder LIT to fix fp-lit-src-equals-dstDave Airlie2011-12-311-8/+8

* tgsi: add support for texture offsets to the TGSI IR. (v2)Dave Airlie2011-09-021-2/+20
| | | | | | | | | | | | | 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.

* tgsi: add TXF support.Dave Airlie2011-08-251-1/+56
| | | | | | | | | | | This is a straight texel fetch with no filtering or clamping. It uses integers to specify the i/j/k (from EXT_gpu_shader4). To enable this I had to add another hook into the tgsi sampler so that we could easily bypass all the filtering sample does.

| | | | | | | | | | | largely a merge of the previously discussed origin/gallium-resource-sampling but updated. the idea is to allow arbitrary binding of resources, the way opencl, new gl versions and dx10+ require, i.e. DCL RES[0], 2D, FLOAT LOAD DST[0], SRC[0], RES[0] SAMPLE DST[0], SRC[0], RES[0], SAMP[0]

* gallium: add a temporary array register fileZack Rusin2010-06-181-1/+95
| | | | | | | | | | | | | | like normal temporaries, but allows to define a number of distinct arrays, all of which make it explicit that they contain /indexable/ registers. as a side-effect we're adding support for multi-dimensional destination registers. The whole thing looks like this: DCL TEMPX[0][0..128] # 0 array with 128 registers ADD TEMPX[0][0], IN[0], IMM[0] ADD TEMPX[0][1], IN[0], IMM[0] ABS OUT[0], TEMPX[0][TEMP[0]]
