* v3d: Fix up VS output setup during precompiles.Eric Anholt2019-01-041-6/+10
| | | | | | | | | I noticed that a VS I was debugging was missing all of its output stores -- outputs_written was for POS, VAR0, VAR3, while the shader's variables were POS, VAR9, and VAR12. I'm not sure what outputs_written is supposed to be doing here, but we can just walk the declared variables and avoid both this bug and the emission of extra stvpms for less-than-vec4 varyings.
* v3d: Refactor compiler entrypoints.Eric Anholt2019-01-021-26/+6
| | | | | | Before, I had per-stage entryoints with some helpers shared between them. As I extended for compute shaders and shader-db, it turned out that the other common code in the middle wanted to be shared too.
* v3d: Don't forget to include RT writes in precompiles.Eric Anholt2019-01-021-0/+10
| | | | | Looking at some assembly dumps for an optimization, we were clearly missing important parts of the shader!
* v3d: Fix segfault when failing to compile a program.Eric Anholt2019-01-021-2/+4
| | | | | | | We'll still fail at draw time, but this avoids a regression in shader-db execution once I enable TLB writes in precompiles. Fixes: b38e4d313fc2 ("v3d: Create a state uploader for packing our shaders together.")
* v3d: Hook up some shader-db output to GL_ARB_debug_output.Eric Anholt2018-12-301-0/+12
| | | | | | | This allows the original shader-db project's run.c runner to parse things easily, and is probably a good thing to have for GL_ARB_debug_output in general. I formatted it more like Intel's so I can mostly reuse their report script.
* v3d: Add a "precompile" debug flag for shader-db.Eric Anholt2018-12-291-0/+76
| | | | | | | | | I've been using my apitrace-based shader-db so far, but it's slow (apitrace decompression), intrusive (apitrace windows spamming the screen), and doesn't have much coverage. The original shader-db provides a lot more coverage and compiles faster, at the expense of not having the actual runtime variant key. As v3d has a lot less runtime variation than vc4 did, this tradeoff makes more sense.
* v3d: Drop shadow comparison state from shader variant key.Eric Anholt2018-12-201-2/+0
| | | | The shadow state is now in the sampler.
* v3d: Make an array for frag/vert texture state in the context.Eric Anholt2018-12-071-2/+2
| | | | | This simplifies a bunch of our texture handling, while introducing the slots necessary for adding new shader stages.
* v3d: Create a state uploader for packing our shaders together.Eric Anholt2018-12-071-9/+13
| | | | | | Shaders are usually quite short, and are private to the context. We can save memory and reduce the work the kernel needs to do at exec time by packing them together in a stream uploader for long-lived state.
* v3d: Use nir_remove_unused_io_vars to handle binner shader output DCEEric Anholt2018-10-301-1/+1
| | | | | | We were doing this late after nir_lower_io, but we can just reuse the core code. By doing it at this stage, we won't even set up the VS attributes as inputs, reducing our VPM size.
* v3d: Use nir_lower_io_to_scalar_early to DCE unused VS input components.Eric Anholt2018-10-301-1/+4
| | | | | This lets us trim unused trailing components in the vertex attributes, reducing the size of our VPM allocations.

* gallium/ttn: Convert inputs and outputs to derefs of variables.Eric Anholt2018-10-151-3/+4
| | | | | | | | | | | This means that TTN shaders more closely resemble GTN shaders: they have inputs and outputs as variable derefs, with the variables having their .driver_location already set up for you. This will be useful for v3d to do input variable DCE in NIR, which we can't do when the TTN shaders never have a pre-nir_lower_io stage. Acked-by: Rob Clark <[email protected]>
* v3d: Implement noperspective varyings on V3D 4.x.Eric Anholt2018-07-091-0/+5
| | | | | Fixes a bunch of piglit interpolation tests, and reduces my concern about some MSAA blit shaders with noperspective varyings.

* v3d: Add proper support for GL_EXT_draw_buffers2's blending enables.Eric Anholt2018-07-051-4/+4
| | | | | I had flagged it as enabled on V3D 4.x, but not actually implemented the per-RT enables. Fixes piglit fbo_drawbuffers2-blend.
* v3d: Convert a bunch of our "minus one" fields over to the new XML attr.Eric Anholt2018-06-271-1/+1
| | | | | This fixes up their formatting for CLIF files and makes the code more legible.
* st,ir3,radeonsi: push lower_deref_instrs back into driverRob Clark2018-06-221-1/+0
| | | | | | | | | | | | | vc4+vc5 is not really effected by the deref chain to deref instr conversion, so it no longer needs this pass. For others, now that all the passes mesa/st uses are using deref instructions, push the lowering to deref chains back into driver.
