* tgsi/scan: use wrap-around shift behavior explicitly for file_maskRoland Scheidegger2018-03-061-1/+1
| | | | | | | | | | | | | | The comment said it will only represent the lowest 32 regs. This was not entirely true in practice, since at least on x86 you'll get masked shifts (unless the compiler could recognize it already and toss it out). It turns out this actually works out alright (presumably noone uses it for temp regs) when increasing max sampler views, so make that behavior explicit. Albeit it feels a bit hacky (but in any case, explicit behavior there is better than undefined behavior). Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* swr: Support simd16 vertex shadersGeorge Kyriazis2018-01-191-12/+30
| | | | | | | | | | | | | | | Supporting simd16 vertex shaders involves packing the output of the fetch shader appropriately, especially the vertexID buffers that have to be formatted in one simd16 register, needed by the VS. As part of this support, we needed to remove the 2nd JitManager, since it was not accounting for vector width correctly. USE_SIMD16_SHADERS is also split into two defines. The additional one (USE_SIMD16_VS) controls the width of the vertex shader (VS), while the original one (USE_SIMD16_SHADERS) controls overall front end width.

* swr: fix transform feedback logicGeorge Kyriazis2017-07-271-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The shader that is used to copy vertex data out of the vs/gs shaders to the user-specified buffer (streamout or SO shader) was not using the correct offsets. Adjust the offsets that are used just for the SO shader: - Make sure that position is handled in the same special way as in the vs/gs shaders - Use the correct offset to be passed in the core - consolidate register slot mapping logic into one function, since it's been calculated in 2 different places (one for calcuating the slot mask, and one for the register offsets themselves Also make room for all attibutes in the backend vertex area. Fixes: - all vtk GL2PS tests - 18 piglit tests (16 ext_transform_feedback tests, arb-quads-follow-provoking-vertex and primitive-type gl_points v2: - take care of more SGV slots in slot mapping logic - trim feState.vsVertexSize - fix GS interface and incorporate GS while calculating vsVertexSize Note that vsVertexSize is used in the core as the one parameter that controls vertex size between all stages, so it has to be adjusted appropriately for the whole vs/gs/fs pipeline. Also note that GS and SO is not fully implemented. This will be addressed later. fixes: - fixes total of 20 piglit tests CC: 17.2 <[email protected]> Reviewed-by: Bruce Cherniak <[email protected]>
* swr/rast: Support dynamically sized vertex layoutTim Rowley2017-06-301-0/+2
| | | | | | | | | | | | | | | Each shader stage state (VS, TS, GS, SO, BE/CLIP) now has a vertexAttribOffset to specify the offset to the start of the general attribute section of the incoming verts for that stage. It is up to the driver to set this up correctly based on the active stages. All the shader stages use this value instead of VERTEX_ATTRIB_START_SLOT to offset to the incoming attributes. Only the vertex shader stage supports dynamic layout output currently. The other stages continue to expect the output to be the fixed layout slots as before. Will be enabling GS next.

* swr: fix crash in swr_update_derived following st/mesa state changesBruce Cherniak2017-03-021-0/+6
| | | | | | | | | | | | | | | | | | | | Recent change to st/mesa state update logic caused major regressions to swr validation code. swr uses the same validation logic (swr_update_derived) for both draw and Clear calls. New st/mesa state update logic results in certain state objects not being set/bound during Clear. This was causing null ptr exceptions. Creation of static dummy state objects allows setting these pointers during Clear validation, without interfering with relevant state validation. Once fixed, new logic also highlighted an error in dirty bit checking for fragment shader and clip validation. (The alternative is to have a simplified validation routine for Clear. Which may do that at some point.) Reviewed-by: Tim Rowley <[email protected]>

* swr: rework resource layout and surface setupIlia Mirkin2016-11-221-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a bit of a mega-commit, but unfortunately there's no great way to break this up since a lot of different pieces have to match up. Here we do the following: - change surface layout to match swr's Load/StoreTile expectations - fix sampler settings to respect all sampler view parameters - fix stencil sampling to read from secondary resource - respect pipe surface format, level, and layer settings - fix resource map/unmap based on the new layout logic - fix resource map/unmap to copy proper parts of stencil values in and out of the matching depth texture These fix a massive quantity of piglits, including all the tex-miplevel-selection ones. Note that the swr native miptree layout isn't extremely space-efficient, and we end up using it for all textures, not just the renderable ones. A back-of-the-envelope calculation suggests about 10%-25% increased memory usage for miptrees, depending on the number of LODs. Single-LOD textures should be unaffected. There are a handful of regressions as a result of this change: - Some textureGrad tests, these failures match llvmpipe. (There are debug settings allowing improved gallivm sampling accurancy.) - Some layered clearing tests as swr doesn't currently support that. It was getting lucky before because enough other things were broken. Signed-off-by: Ilia Mirkin <[email protected]> Reviewed-by: Bruce Cherniak <[email protected]>
