* gallium/docs: fix up transfer description for 1d arrays, add cube map arraysRoland Scheidegger2013-06-071-5/+4
| | | | | | | | | | | Transfers always use z/depth for layers no matter if it's a 1d or 2d array texture, we don't follow OpenGL's crazyness there. Luckily this appears to only be a doc bug, everyone doing the right thing already. While here also document z/depth parameter for cube map arrays. v2: fix typo spotted by Eric Anholt Reviewed-by: Jose Fonseca <[email protected]>
* gallium: add support for layered renderingRoland Scheidegger2013-06-011-2/+20
| | | | | | | | | | Since pipe_surface already has all the necessary fields no interface changes are necessary except adding a new shader semantic value (TGSI_SEMANTIC_LAYER). (Note that what GL knows as "gl_Layer" variable d3d10 is naming "RENDER_TARGET_ARRAY_INDEX".) v2: drop cap bit (just tied to geometry shader), add docs.

* gallium: more tgsi documentation updatesRoland Scheidegger2013-05-071-131/+250
| | | | | | | | | Adds the remaining integer opcodes, and some opcodes are moved to more appropriate places, along with getting rid of the (already nearly empty) ps_2_x section. Though the CAP bits for some of these are still a bit in the air so the documentation isn't quite as watertight as is desirable. Reviewed-by: Jose Fonseca <[email protected]>

* st/mesa: optionally apply texture swizzle to border color v2Christoph Bumiller2013-04-182-2/+15
| | | | | | | | | | | | 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. The dependency of update_sampler on the texture updates was introduced to avoid doing the apply_depthmode to the swizzle twice. v2: Moved swizzling helper to u_format.c, extended the CAP to provide more accurate information.
* gallium: Disambiguate TGSI_OPCODE_IF.José Fonseca2013-04-171-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | texel offsets should have been the last missing feature for 130, and in fact 140 as well (last there were texture buffers). In any case we still don't do OpenGL 3.0 (missing MSAA which will be difficult, plus EXT_packed_float, ARB_depth_buffer_float and EXT_framebuffer_sRGB). v2: bump to 140 instead - we have everything except we crash when not writing to gl_Position (but softpipe crashes as well) so let's just say this is a bug instead.

| | | | | | | | | | | This clarifies some things and gets rid of some old stuff. The most significant one is probably that buffers cannot have formats (nearly all drivers completely ignored format and used width0 as byte size already in any case). There seems to be no use case for "structured" buffers. (Note while d3d11 has new Structured Buffers, these still aren't associated with a format, rather a byte stride, which we can't do yet either way.) Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | | | | | | | Need to take the type into account. Also, if we want to allow mov's with modifiers we need to pick a type (assume float). v2: don't allow all modifiers on all type, in particular don't allow absolute on non-float types and don't allow negate on unsigned. Also treat UADD as signed (despite the name) since it is used for handling both signed and unsigned integer arguments and otherwise modifiers don't work. Also add tgsi docs clarifying this.

* gallium: fix tgsi SAMPLE_L opcode to use separate source for explicit lodRoland Scheidegger2013-02-121-4/+3
| | | | | | | | | | | | | | | | | | | | | It looks like using coord.w as explicit lod value is a mistake, most likely because some dx10 docs had it specified that way. Seems this was changed though: http://msdn.microsoft.com/en-us/library/windows/desktop/hh447229%28v=vs.85%29.aspx - let's just hope it doesn't depend on runtime build version or something. Not only would this need translation (so go against the stated goal these opcodes should be close to dx10 semantics) but it would prevent usage of this opcode with cube arrays, which is apparently possible: http://msdn.microsoft.com/en-us/library/windows/desktop/bb509699%28v=vs.85%29.aspx (Note not only does this show cube arrays using explicit lod, but also the confusion with this opcode: it lists an explicit lod parameter value, but then states last component of location is used as lod). (For "true" hw drivers, only nv50 had code to handle it, and it appears the code was already right for the new semantics, though fix up the seemingly wrong c/d arguments while there.) v2: fix comment, separate out other changes.

* gallivm: fix up size queries for dx10 sviewinfo opcodeRoland Scheidegger2013-02-081-1/+1
| | | | | | | | | | | | | | | Need to calculate the number of mip levels (if it would be worthwile could store it in dynamic state). While here, the query code also used chan 2 for the lod value. This worked with mesa state tracker but it seems safer to use chan 0. Still passes piglit textureSize (with some handwaving), though the non-GL parts are (largely) untested. v2: clarify and expect the sviewinfo opcode to return ints, not floats, just like the OpenGL textureSize (dx10 supports dst modifiers with resinfo). Also simplify some code. Reviewed-by: Jose Fonseca <[email protected]>
* gallium: add SQRT shader opcodeBrian Paul2013-02-041-0/+9
| | | | | | | | | | | | | | | | | | The glsl-to-tgsi translater will emit SQRT to implement GLSL's sqrt() and distance() functions if the PIPE_SHADER_CAP_TGSI_SQRT_SUPPORTED query says it's supported by the driver. Otherwise, sqrt(x) is implemented with x*rsq(x). The problem with this is sqrt(0) must be handled specially because rsq(0) might be Inf/NaN/undefined (and then 0*rsq(0) is Inf/Nan/undefined). In the glsl-to-tgsi code we use an extra CMP to check if x is zero and then replace the result of x*rsq(x) with zero. In the end, this makes sqrt() generate much more reasonable code for drivers that can do square roots. Note that many of piglit's generated shader tests use the GLSL distance() function.
