* softpipe: don't use samplers with prebaked sampler and sampler_view stateRoland Scheidegger2013-03-116-866/+779
| | | | | | | | | | | | | | This is needed for handling the dx10-style sample opcodes. This also simplifies the logic by getting rid of sampler variants completely (sampler_views though OTOH have sort of variants because some of their state is different depending on the shader stage they are bound to). No significant performance difference (openarena run: 840 frames in 459.8 seconds vs. 840 frames in 460.5 seconds). v2: fix reference counting bug spotted by Jose.

* tgsi: add texel offsets and derivatives to sampler interfaceRoland Scheidegger2013-03-021-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | 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 Scheidegger2013-02-288-117/+186
| | | | | | | | | | | | | | | 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 Scheidegger2013-02-082-70/+93
| | | | | | | | | | | | | | | 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.

* softpipe: get rid of tgsi_sampler_control param in img_filterRoland Scheidegger2013-02-082-40/+37

* softpipe: fix using optimized filter functionRoland Scheidegger2013-02-081-0/+1
| | | | | | | | | | | This optimized filter (when using repeat wrap modes, linear min/mag/mip filters, pot textures) only applies to 2d textures, but nothing prevented it from being used for other textures (likely leading to very bogus sample results).

* softpipe: fix up FS variant unbinding / deletionBrian Paul2012-12-193-11/+9
| | | | | | | | | | | | The old call to tgsi_exec_machine_bind_shader() in softpipe_delete_fs_state() was never called since the shader's original tokens are never passed to the tgsi interpreter (only shader _variant_ tokens are). Now, unbind the variant's tokens from the tgsi interpreter when we free the variant. This doesn't fix any known bugs but it's the right thing to do. Note: This is a candidate for the stable branches.
* softpipe: fix unreliable FS variant binding bugBrian Paul2012-12-193-14/+10
| | | | | | | | | | | | | In exec_prepare() we were comparing pointers to see if the fragment shader variant had changed before calling tgsi_exec_machine_bind_shader(). This didn't work reliably when there was a lot of shader token malloc/ freeing going on because the memory might get reused. Instead, bind the shader variant during regular state validation. Fixes http://bugs.freedesktop.org/show_bug.cgi?id=40404 (fixes a couple of piglit's glsl-max-varyings test) Note: This is a candidate for the stable branches.
* draw: add support for later transform feedback extensionsDave Airlie2012-12-141-1/+1

It should be possible to enable them on llvmpipe as well after this commit, but would need to schedule piglit runs. Signed-off-by: Dave Airlie <[email protected]>

* gallium: add start_slot parameter to set_vertex_buffersMarek Olšák2012-10-313-8/+12
| | | | | | | | | | | | | | | | | | | | | This allows updating only a subrange of buffer bindings. set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that range. Binding NULL resources unbinds buffers too (both buffer and user_buffer must be NULL). The meta ops are adapted to only save, change, and restore the single slot they use. The cso_context can save and restore only one vertex buffer slot. The clients can query which one it is using cso_get_aux_vertex_buffer_slot. It's currently set to 0. (the Draw module breaks if it's set to non-zero) It should decrease the CPU overhead when using a lot of meta ops, but the drivers must be able to treat each vertex buffer slot as a separate state (only r600g does so at the moment). I can imagine this also being useful for optimizing some OpenGL use cases. Reviewed-by: Brian Paul <[email protected]>
