* gallivm/gs: fix indirect addressing in geometry shadersZack Rusin2013-04-173-6/+30
| | | | | | | | | | | We were always treating the vertex index as a scalar but when the shader is using indirect addressing it will be a vector of indices for each channel. This was causing some nasty crashes insides LLVM. Signed-off-by: Zack Rusin <[email protected]> Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
* draw/gs: make sure geometry shaders don't overflowZack Rusin2013-04-165-11/+81
| | | | | | | | | | | | | | The specification says that the geometry shader should exit if the number of emitted vertices is bigger or equal to max_output_vertices and we can't do that because we're running in the SoA mode, which means that our storing routines will keep getting called on channels that have overflown (even though they will be masked out, but we just can't skip them). So we need some scratch area where we can keep writing the overflown vertices without overwriting anything important or crashing.

* draw: implement pipeline statistics in the draw moduleZack Rusin2013-04-1610-20/+112
| | | | | | | | | | | | | This is a basic implementation of the pipeline statistics in the draw module. The interface is similar to the stream output statistics and also requires that the callers explicitly enable it. Included is the implementation of the interface in llvmpipe and softpipe. Only softpipe enables the pipeline statistics capability though because llvmpipe is lacking gathering of the fragment shading and rasterization statistics.

* gallivm/gs: fix the end primitive callsZack Rusin2013-04-162-27/+50
| | | | | | | | | | | | | | | The issue with SOA execution and end_primitive opcode is that it can be executed both when we haven't emitted any vertices, in which case we don't want to emit an empty primitive, and when the execution mask is zero and the execution should be skipped. We handled only the latter of those conditions. Now we're combining the execution mask with a mask created from emitted vertices to handle both cases. As a result we don't need the pending_end_primitive flag which was broken because it was static and could be affected by both above mentioned conditions at run-time.

* gallium: Disambiguate TGSI_OPCODE_IF.José Fonseca2013-04-178-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_IF condition had two possible interpretations: - src.x != 0.0f - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was false either for vertex and fragment shaders - gallivm/llvmpipe - postprocess - vl state tracker - vega state tracker - most old drivers - old internal state trackers - many graw examples - src.x != 0U - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was true for both vertex and fragment shaders - tgsi_exec/softpipe - r600 - radeonsi - nv50 And drivers that use draw module also were a mess (because Mesa would emit float IFs, but draw module supports native integers so it would interpret IF arg as integers...) This sort of works if the source argument is limited to float +0.0f or +1.0f, integer 0, but would fail if source is float -0.0f, or integer in the float NaN range. It could also fail if source is integer 1, and hardware flushes denormalized numbers to zero. But with this change there are now two opcodes, IF and UIF, with clear meaning. Drivers that do not support native integers do not need to worry about UIF. However, for backwards compatibility with old state trackers and examples, it is advisable that native integer capable drivers also support the float IF opcode. I tried to implement this for r600 and radeonsi based on the surrounding code. I couldn't do this for nouveau, so I just shunted IF/UIF together, which matches the current behavior.

* gallivm: fix small but severe bug in handling multiple lod level stridesRoland Scheidegger2013-04-151-1/+1
| | | | | | | | | | | | | | | | | Inserting the value for the second quad in the wrong place for the following shuffle. This meant the row or image stride was undefined which is quite catastrophic, can lead to bogus texels fetched or just segfault. This code is only hit for SoA path currently, still surprising it didn't crash more or caused more visible issues (I think llvm used a broadcast shuffle for the undefined parts of the vector, hence the undefined value for the second quad was just the same as that from the first quad, so as long as both quads hit the same mip level everything was fine, and since lower mips always have the same large stride it made it less likely to hit out-of-bound memory in case of differing lods).

* gallivm: some minor cube map cleanupRoland Scheidegger2013-04-041-10/+15
| | | | | | | | | | | | | | | The ar_ge_as_at variable was just very very confusing since the condition was actually the other way around (as_at_ge_ar). So change the condition (and the selects depending on it) to match the variable name. And also change the chosen major axis in case the coord values are the same. OpenGL doesn't care one bit which one is chosen in this case but it looks like dx10 would require z chosen over y, and y chosen over x (previously did x chosen over y, y chosen over z). Since it's all the same effort just honor dx10's wishes. (Though actually, for some prefered orderings, we could save one (or two with derivatives) selects since the tnewx and tnewz (and the corresponding dmax values) are the same.)

* gallivm: do per-pixel cube face selection (finally!!!)Roland Scheidegger2013-04-043-82/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This proved to be tricky, the problem is that after selection/mirroring we cannot calculate reasonable derivatives (if not all pixels in a quad end up on the same face the derivatives could get "randomly" exceedingly large). However, it is actually quite easy to simply calculate the derivatives before selection/mirroring and then transform them similar to the cube coordinates (they only need selection/projection, but not mirroring as we're not interested in the sign bit, of course). While there is a tiny bit more work to do (need to calculate derivs for 3 coords instead of 2, and additional selects) it also simplifies things somewhat for the coord selection itself (as we save some broadcast aos shuffles, and we don't need to calculate the average vector) - hence if derivatives aren't needed this should actually be faster. Also, this has the benefit that this will (trivially) work for explicit derivatives too, which we completely ignored before that (will be in a separate commit for better trackability). Note that while the way for getting rho looks very different, it should result in "nearly" the same values as before (the "nearly" is only because before the code would choose the face based on an "average" vector and hence the derivatives calculated according to this face, where now (for implicit derivatives) the derivatives are projected on the face selected for the first (top-left) pixel in a quad, so not necessarly the same face). The transformation done might not quite be state-of-the-art, calculating length(dx,dy) as max(dx,dy) certainly isn't neither but this stays the same as before (that is I think a better transform would _somehow_ take the "derivative major axis" into account so that derivative changes in the major axis wouldn't get ignored). Should solve some accuracy problems with cubemaps (can easily be seen with the cubemap demo when switching wrapping/filtering), though we still don't do seamless filtering to fix it completely (so not per-sample but per-pixel is certainly better than per-quad and already sufficient for accurate results with nearest tex filter). As for performance, it seems to be a tiny bit faster too (maybe 3% or so with cubemap demo). Which I'd have expected with nearest/nearest filtering where this will be less instructions, but the difference seems to actually be larger with linear/linear_mipmap_linear where it is slightly more instructions, probably the code appears less serialized allowing better scheduling (on a sandy bridge cpu). It actually seems to be now at least as fast as the old path using a conditional when using 128bit vectors too (that is probably more a result of testing with a newer cpu though), for now that old path is still there but unused. No piglit regressions. Reviewed-by: Jose Fonseca <[email protected]>
