significant changes to last series:
* support for geometry, tessellation and compute shaders
* support for more intrinsics and operations
* lot of fixes for 64 bit types
* NV50_PROG_USE_NIR=1 can be used to enable NIR for non debug builds
There are some outstanding issues triggered by having 64 bit loads and
nir_compact_varyings also does some harm. But I think the current state is
quite good and a lot of things will work out of the box already.
I mainly tested with piglit, unigine heaven and valley. RealisticRendering Demo
doesn't run yet, but this might be related to some 64bit or memory related
issues.
It would be nice if others could just run some games/tests with it and report
back where things are still broken, so that the focus can be on fixing real
issues instead of trying to pass all tests first.
./piglit run -x glx -x egl -x streaming-texture-leak -x max-texture-size
tests/gpu.py:
[26073/26073] skip: 1640, pass: 20773, warn: 9, fail: 1548, crash: 2103
the biggest todos looking at the piglit results are:
* arb_gpu_shader5 interpolateat* (those nir ops don't map well to nvir)
no good plan on how to properly implement those
* arb_gpu_shader5.texturegatheroffsets (nir internal assert)
glsl_to_nir.cpp:2082: virtual void
{anonymous}::nir_visitor::visit(ir_texture*): Assertion
`ir->offset->type->is_vector() || ir->offset->type->is_scalar()' failed.
* some int64 stuff related to compound types
* various extensions
* variable-indexing (related to above mentioned packing issue)
* glsl-4.20.execution.vs_in
* some variable-indexing issues related to unaligned memory accesses
* some geometry shader fails
