* tgsi, softpipe: Constify tgsi_sampler in query_lod vfuncKrzesimir Nowak2015-09-111-1/+1
| | | | | | | | | | A followup from previous commit - since all functions called by query_lod take pointers to const sp_sampler_view and const sp_sampler, which are taken from tgsi_sampler subclass, we can the tgsi_sampler as const itself now.

* tgsi: Add code for handling lodq opcodeKrzesimir Nowak2015-09-101-0/+10
| | | | | | | | | | | | This introduces new vfunc in tgsi_sampler just for this opcode. I decided against extending get_samples vfunc to return the mipmap level and LOD - the function's prototype is already too scary and doing the sampling for textureQueryLod would be a waste of time. v2: - splitted too long lines Reviewed-by: Brian Paul <brianp@vmware.com>

| | | | | | | | | | | | | | | This limit is fixed in Mesa core and cannot be changed. It only affects ARB_vertex_program and ARB_fragment_program. The minimum value for ARB_vertex_program is 1 according to the spec. The maximum value for ARB_vertex_program is limited to 1 by Mesa core. The value should be zero for ARB_fragment_program, because it doesn't support ARL. Finally, drivers shouldn't mess with these values arbitrarily. Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu>

* tgsi: add texel offsets and derivatives to sampler interfaceRoland Scheidegger2013-03-021-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | Something I never got around to implement, but this is the tgsi execution side for implementing texel offsets (for ordinary texturing) and explicit derivatives for sampling (though I guess the ordering of the components for the derivs parameters is debatable). There is certainly a runtime cost associated with this. Unless there are different interfaces used depending on the "complexity" of the texture instructions, this is impossible to avoid. Offsets are always active (I think checking if they are active or not is probably not worth it since it should mostly be an add), whereas the sampler_control is extended for explicit derivatives. For now softpipe (the only user of this) just drops all those new values on the floor (which is the part I never implemented...). Additionally this also fixes (discovered by accident) inconsistent projective divide for the comparison coord - the code did do the projection for shadow2d targets, but not shadow1d ones. This also drops checking for projection modifier on array targets, since they aren't possible in any extension I know of (hence we don't actually know if the array layer should also be divided or not).

* softpipe/draw/tgsi: simplify driver/tgsi sampler interfaceRoland Scheidegger2013-02-281-9/+13
| | | | | | | | | | | | | | | Use a single sampler adapter instead of per-sampler-unit samplers, and just pass along texture unit and sampler unit in the calls. The reason is that for dx10-style sample opcodes pre-wired samplers including all the texture state aren't really feasible (and for sample_i/sviewinfo we don't even have samplers). Of course right now softpipe doesn't actually do anything more than just look up all its pre-wired per-texunit/per-samplerunit sampler as it did before so this doesn't really achieve much except one more function call, however this is now all softpipe's fault (fixing that in a way which doesn't suck is still an unsolved problem).

* softpipe: clean up lod computationRoland Scheidegger2013-02-081-6/+8
| | | | | | | | | | | | | | | This should handle the new lod_zero modifier more correctly. The runtime-conditional is a bit more complex however we now also do scalar lod computation when appropriate which should more than make up for it. The refactoring should also fix an issue with explicit lods (lod clamp wasn't applied to them). Also, always pass lod as the 5th element from tgsi executor, which simplifies things (get rid of annoying conditionals later). v2: based on Brian's feedback, use switch in a couple of places, fix up some function parameter names, fix up comments.

* gallium/tgsi: Split sampler views from shader resources.Francisco Jerez2012-05-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes in v3: - Also change trace, which I forgot about Changes in v2: - No longer adds tessellation shaders Currently each shader cap has FS and VS versions. However, we want a version of them for geometry, tessellation control, and tessellation evaluation shaders, and want to be able to easily query a given cap type for a given shader stage. Since having 5 duplicates of each shader cap is unmanageable, add a new get_shader_param function that takes both a shader cap from a new enum and a shader stage. Drivers with non-unified shaders will first switch on the shader and, within each case, switch on the cap. Drivers with unified shaders instead first check whether the shader is supported, and then switch on the cap. MAX_CONST_BUFFERS is now per-stage. The geometry shader cap is removed in favor of checking whether the limit of geometry shader instructions is greater than 0, which is also used for tessellation shaders.
