* r600g: initialize CMASK and HTILE with the GPU using streamoutMarek Olšák2013-04-234-7/+80
| | | | | | | | | | | | | This fixes a crash when a resource cannot be mapped to the CPU's address space because it's too big. This puts a global pipe_context in r600_screen, which is guarded by a mutex, so that we can use pipe_context when there isn't one around. Hopefully our multi-context support is solid.

* gallivm: implement switch opcodeRoland Scheidegger2013-04-203-12/+340
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Should be able to handle all things which make this tricky to implement. Fallthroughs, including most notably into/out of default, should be handled correctly but are quite a mess. If we see largely unoptimized switches in the wild should probably think about some "real" switch optimization pass, e.g. things like this: switch case1 someinst brk case2 default case3 someinst brk case4 someinst endswitch are legal, but the pointless case2/case3 statements not only cause condition evaluation but will turn this into a "fake" fallthrough case (because mask and defaultmask are already updated for case2 when default is encountered) requiring executing code twice. If default is at the end though, there's never any code re-execution, and if that's not the case if there's no fallthrough in (not even a fake one) and out of default there's no code re-execution neither. v2: add comments, and use enum for break type instead of magic boolean.

* gallivm: increase nesting limit to 66Roland Scheidegger2013-04-201-2/+4
| | | | | | | | | | | This is still not really correct, since at least for sm 4.0 the nesting limit is 64 per subroutine, and subroutine nesting itself has a limit of 32, so since we have a flat stack we'd need 32*64. But this should probably be better fixed with per-subroutine stacks, since otherwise these structures get really big (like 100kB for the lp_exec_mask). Reviewed-by: Jose Fonseca <[email protected]>
* draw: implement primitive assemblerZack Rusin2013-04-187-4/+386
| | | | | | | | | | | | | | | | | | | | Input assembler needs to be able to decompose adjacency primitives into something that can be understood by the rest of the pipeline. The specs say that the adjacency primitives are *only* visible in the geometry shader, for everything else they need to be decomposed. Which in most of the cases is not an issue, because the geometry shader always decomposes them for us, but without geometry shader we were passing unchanged adjacency primitives to the rest of the pipeline and causing crashes everywhere. This commit introduces a primitive assembler which, if geometry shader is missing and the input primitive is one of the adjacency primitives, decomposes them into something that the rest of the pipeline can understand.

* mesa: Use quotes on bool driconf options to prevent stdbool.h breakage.Eric Anholt2013-04-191-4/+4
| | | | | | | | | | | | | Since stdbool.h's "true" and "false" are #defines, they got expanded when used as macro arguments, and that expanded value was stored in the XML string, producing XML that driconf would then fail to parse.

| | | | | | | | | | | | This is the only sane solution for nv50 and nvc0 (really, trust me), but since on other hardware the border colour is tightly coupled with texture state they'd have to undo the swizzle, so I've added a cap.

* gallivm: change cubemaps / derivatives handling, take 55Roland Scheidegger2013-04-183-104/+119
| | | | | | | | | | | | | | | | | | | | | | | Turns out the previous "fix" for handling per-pixel face selection and derivatives didn't work out that well - the derivatives were wrong by quite a bit, in theory transformation of the derivatives into cube space should work, but would be _a lot_ more work than the "simplified" transform used. So, for explicit derivatives, I'm just giving up and go back to not honoring them. For implicit derivatives (and the fake explicit ones) however we try something a little different, we just calculate rho as we would for a 3d texture, that is after scaling the coords by the inverse major axis. This gives the same results as calculating the derivs after projection of the coords to the same face as long as all pixels hit the same face (and only without rho_no_opt, otherwise it should be a bit worse). And when not all pixels are hitting the same face, the results aren't so hot but not catastrophically bad (I believe not off by more than a factor of 2 without no_rho_approx and not more than sqrt(2) with no_rho_approx). I think this is better than just picking the wrong face but who knows... Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>
* gallivm: Add no_rho_approx debug optionRoland Scheidegger2013-04-183-118/+185
| | | | | | | | | | | | | | | | | | | | | This will calculate rho correctly as sqrt(max((ds/dx)^2 + (dt/dx)^2 + (dr/dx)^2), (ds/dx)^2 + (dt/dx)^2 + (dr/dx)^2)) instead of max(|ds/dx|,|dt/dx|,|dr/dx|,|ds/dy|,|dt/dy,|dr/dy|) (for 3 coords - 2 coords work analogous, for 1 coord there's no point doing the exact version), for both implicit and explicit derivatives. While such approximation seems to be allowed in OpenGL some APIs may be less forgiving, and the error can be quite large (sqrt(2) for 2 coords, sqrt(3) for 3 coords so wrong by nearly one mip level in the latter case). This also helps to single out "real" bugs from "expected" ones, so it is debug only (though at least combined with no_brilinear I didn't really see much of a performance difference but only tested with a debug build - at least with implicit mipmaps the instruction count is almost exactly the same though the instructions are more complex (1 sqrt and mul/adds instead of and/max mostly). The code when the option isn't set stays exactly the same. v2: rename no_rho_opt to no_rho_approx. Reviewed-by: Brian Paul <[email protected]>
