What happened?

Hi! I have noticed that the CUDA example for custom dispatch is broken.

This is the stack trace:

iree-compile: iree/third_party/llvm-project/llvm/include/llvm/Support/Casting.h:572: decltype(auto) llvm::cast(From &) [To = mlir::iree_compiler::PartitionableLoopsInterface, From = mlir::Operation]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
Please report issues to https://github.com/iree-org/iree/issues and include the crash backtrace.

The failing line is not in there, so jumping in with the debugger, this line failes:

iree/compiler/src/iree/compiler/Codegen/LLVMGPU/KernelConfig.cpp

Line 1662 in 6245db1

auto interfaceOp = cast<PartitionableLoopsInterface>(*op);

The op it tries to cast is the ukernel op

%8 = iree_codegen.ukernel.generic "simple_mul_workgroup" ins(%5, %6 : tensor<?xf32>, tensor<?xf32>) outs(%7 : tensor<?xf32>) (%4 : index) strided_outer_dims(0) -> tensor<?xf32>

Seems like some special casing for that op is missing in

iree/compiler/src/iree/compiler/Codegen/LLVMGPU/KernelConfig.cpp

Line 2341 in 6245db1

static LogicalResult setRootConfig(IREE::GPU::TargetAttr target,

It hink this PR broke it, because it removed the lowering config #19504 @bjacob I know there is this new approach to ukernels on GPU. Is the plan to fully remove the old one?

Also @benvanik, because you seem to have build the example.

Steps to reproduce your issue

Compile IREE with CUDA and samples on.

Oh, we don't care much about that sample anymore. It was mostly just a stepping stone towards ukernels. We could just remove it, or we could not build it on CUDA.

Ah, I can't reproduce due to #17933:

iree/samples/custom_dispatch/cuda/kernels/CMakeLists.txt

Lines 11 to 15 in a88555c

# TODO(#17933): fix cuda_ukernel_unkernel.cu.bc compilation on MSVC (use compiler-rt?)
if(MSVC)
message(STATUS "IREE custom_dispatch/cuda/kernels example ignored -- #17933 required to make MSVC work")
return()
endif()

Would be nice to have CI coverage for CUDA on Linux again: #18814.
