2024-08-27	[mlir][gpu] Add metadata attributes for storing kernel metadata in GPU ↵	Fabian Mora
	objects (#95292) This patch adds the `#gpu.kernel_metadata` and `#gpu.kernel_table` attributes. The `#gpu.kernel_metadata` attribute allows storing metadata related to a compiled kernel, for example, the number of scalar registers used by the kernel. The attribute only has 2 required parameters, the name and function type. It also has 2 optional parameters, the arguments attributes and generic dictionary for storing all other metadata. The `#gpu.kernel_table` stores a table of `#gpu.kernel_metadata`, mapping the name of the kernel to the metadata. Finally, the function `ROCDL::getAMDHSAKernelsELFMetadata` was added to collect ELF metadata from a binary, and to test the class methods in both attributes. Example: ```mlir gpu.binary @binary [#gpu.object<#rocdl.target<chip = "gfx900">, kernels = #gpu.kernel_table<[ #gpu.kernel_metadata<"kernel0", (i32) -> (), metadata = {sgpr_count = 255}>, #gpu.kernel_metadata<"kernel1", (i32, f32) -> (), arg_attrs = [{llvm.read_only}, {}]> ]> , bin = "BLOB">] ``` The motivation behind these attributes is to provide useful information for things like tunning. --------- Co-authored-by: Mehdi Amini <joker.eph@gmail.com>
2024-08-27	[mlir][gpu] Pass GPU module to `TargetAttrInterface::createObject`. (#94910)	Fabian Mora
	This patch adds an argument to `gpu::TargetAttrInterface::createObject` to pass the GPU module. This is useful as `gpu::ObjectAttr` contains a property dict for metadata, hence the module can be used for extracting things like the symbol table and adding it to the property dict. --------- Co-authored-by: Oleksandr "Alex" Zinenko <ftynse@gmail.com>

2023-11-05	[mlir][spirv] Implement gpu::TargetAttrInterface (#69949)	Sang Ik Lee
	This commit implements gpu::TargetAttrInterface for SPIR-V target attribute. The plan is to use this to enable GPU compilation pipeline for OpenCL kernels later. The changes do not impact Vulkan shaders using milr-vulkan-runner. New GPU Dialect transform pass spirv-attach-target is implemented for attaching attribute from CLI. gpu-module-to-binary pass now works with GPU module that has SPIR-V module with OpenCL kernel functions inside.
