* vc4: Add initial support for math opcodesEric Anholt2014-08-082-1/+41

* vc4: Switch to actually generating vertex and fragment shader code from TGSI.Eric Anholt2014-08-0812-247/+1243
| | | | | | | | | | | | | | | | | | This introduces an IR (QIR, for QPU IR) to do optimization on. It's a scalar, SSA IR in general. It looks like optimization is pretty easy this way, though I haven't figured out if it's going to be good for our weird register allocation or not (or if I want to reduce to basically QPU instructions first), and I've got some problems with it having some multi-QPU-instruction opcodes (SEQ and CMP, for example) which I probably want to break down. Of course, this commit mostly doesn't work, since many other things are still hardwired, like the VBO data. v2: Rewrite to use a bunch of helpers (qir_OPCODE) for emitting QIR instructions into temporary values, and make qir_inst4 take the 4 args separately instead of an array (all later callers wanted individual args).
* vc4: Start converting the driver to use vertex shaders.Eric Anholt2014-08-083-45/+177
| | | | | | | | Note: This is the cutoff point where I switched from developing primarily on the Pi to developing o the simulator. As a result, from this point on the code is untested on the Pi (the kernel code I have currently wasn't rendering anything at this commit, though the simulator renders successfully, suggesting kernel bugs).
* vc4: Initial skeleton driver import.Eric Anholt2014-08-0833-0/+4608
| | | | | | | | | | | | | | | | | | | This mostly just takes every draw call and turns it into a sequence of commands that clear the FBO and draw a single shaded triangle to it, regardless of the actual input vertices or shaders. I copied the initial driver skeleton mostly from freedreno, and I've preserved Rob Clark's copyright for those. I also based my initial hardcoded shaders and command lists on Scott Mansell (phire)'s "hackdriver" project, though the bit patterns of the shaders emitted end up being different. v2: Rebase on gallium megadrivers changes. v3: Rebase on PIPE_SHADER_CAP_MAX_CONSTS change. v4: Rely on simpenrose actually being installed when building for simulation. v5: Add more header duplicate-include guards. v6: Apply Emil's review (protection against vc4 sim and ilo at the same time, and dropping the dricommon drm bits) and fix a copyright header (thanks, Roland)

* draw: don't use clipvertex output if user plane clipping is disabledRoland Scheidegger2014-08-091-2/+2
| | | | | | | | | | The non-llvm path made sure that both clip and pre_clip_pos point to the data output by position, not clipvertex, if user based clipping is disabled. However, the llvm path did not, which apparently led to failures if gl_ClipVertex was written but user plane clipping not enabled (bug 80183). Why I have no idea really, but just make it match the non-llvm behavior... Reviewed-by: Brian Paul <[email protected]>
* gallivm: Handle MSAA textures in emit_fetch_texelsDarius Goad2014-08-081-2/+7
| | | | | | | | | | | | This support is preliminary due to the fact that MSAA is not actually implemented. However, this patch does fix the piglit test: spec/!OpenGL 3.2/glsl-resource-not-bound 2DMS (bug #79740).

* draw: hack around weird primitive id input in gsRoland Scheidegger2014-08-083-5/+21
| | | | | | | | | | | | | | | | | | | | | | The distinction between system values and ordinary inputs is not very obvious in gallium - further fueled by the fact that they use the same semantic names. Still, if there's any value which imho really is a system value, it's the primitive id input into the gs (while earlier (tessleation) stages could read it, it is _always_ generated by the system). For some odd reason though (which I'd classify as a bug but seems too complicated to fix) the glsl compiler in mesa treats this as an ordinary varying, and everything else after that (including the state tracker and other drivers) just go along with that. But input fetching in gs for llvm based draw was definitely limited to the ordinary (2-dimensional) inputs so only worked with other state trackers, the code was also additionally relying on tgsi_scan_shader filling uses_primid correctly which did not happen neither (would set it only for all stages if it was a system value, but only set it for the fragment shader if it was an input value). This fixes piglit glsl-1.50-geometry-primitive-id-restart and primitive-id-in in llvmpipe. Reviewed-by: Brian Paul <[email protected]>

* draw: fix clipvertex trouble if position comes from gsRoland Scheidegger2014-08-061-1/+5
| | | | | | | | | | | | | | | If the vertex shader has no position but the gs has, the clipvertex output was -1 (because it's the same as vs position in this case if there's no explicit clipvertex output). This caused crashes (or assertion failures) in clipping since in the end position (which came from gs) was different from cv (-1) and we then tried to use the bogus cv input. Rather than just test for -1 cv value in clipping, make it explicitly return the position output of the gs instead which seems cleaner (since we really don't want to use the clipvertex value from the vs (it could be a valid value in the (unsupported) case of vs writing clipvertex but still using a gs). This fixes piglit shader_runner clip-distance-out-values.shader_test. Reviewed-by: Zack Rusin <[email protected]>
* draw: don't run pipeline stages when gs has no position outputRoland Scheidegger2014-08-062-1/+5
| | | | | | | | | | | | | | | | The clip stage may crash if there's no position output, for this reason code was added to avoid running the pipeline stages in this case (c7c7186045ec617c53f7899280cbe12e59503e4d). However, this failed to actually work when there was a geometry shader, since unlike the vertex shader it did not initialize the position output to -1, hence the code trying to detect this didn't trigger. So simply initialize the position output to -1 just like the vs does. This fixes piglit glsl-1.50-transform-feedback-type-and-size (segfault->pass). clip-distance-out-values.shader_test goes from segfault to assertion failure, suggesting more fixes are needed, no other piglit changes.

| | | | | | | | | | | | | | | | This could be recalculated, though it turns out the only use of it after resource allocation is for calculating whole resource size (for scene size accounting though that isn't quite ideal neither). Thus, instead just store the whole resource size and drop it (saving a couple bytes of storage per resource). It makes things simpler too.

| | | | | | | | | | | | | | | | | | | When using (d3d10) conformant out-of-bound behavior for texel fetching (currently always enabled) the level still needs to be set to a safe value even though the offset in the end won't get used because the level is used to look up the mip offset itself and the actual strides, which might otherwise crash. For simplicity, we'll use level 0 in this case (this ought to be safe, llvmpipe does not actually fill in level 0 information if first_level is larger, but some random strides / offsets shouldn't hurt as ultimately we always use offset 0 in this case). Fixes a crash in some in-house test where random huge levels appear in lp_build_fetch_texel() (the test actually uses level 0 always but if the fetching happens in a block with a execution mask random values may appear).
