I haven't investigated what's happening in detail. However vkd3d
emits this message, which makes me think the problem is ours:
vkd3d:62178588:fixme:spirv_compiler_get_descriptor_binding Could not find descriptor binding for type 0, space 0, registers [0:2], shader type 0.
Most of them fail on any native implementation I can put my hands
on, including the CI. Equivalent, but hopefully better, tests
were added to arithmetic-uint.shader_test and
arithmetic-int-uniform.shader_test.
We currently check that non-shader-visible heaps have a NULL
handle, but that doesn't seem to be guaranteed: beside WARP, also
NVIDIA drivers still return a valid pointer. And that's a pretty
useless check anyway; rather, check that shader-visible heaps
have a valid pointer, which is more interesting.
Currently the tests expect that creating buffers in COMMON or
COPY_SOURCE state on UPLOAD heaps or in COMMON state on READBACK
heaps leads to a failure. I tested WARP, AMD and NVIDIA, and in
all cases the operations is successful.
I think the D3D12 runtime used reject resources created in the
configurations detailed above, but it doesn't any more (both
using the latest Agility SDK and the runtime distributed with
an updated Windows 11 system). However the CI still uses an
earlier runtime, so the old behavior is still allowed as
broken.
