◆ getAMDHSAKernelsELFMetadata()

std::optional< DenseMap< StringAttr, NamedAttrList > > mlir::ROCDL::getAMDHSAKernelsELFMetadata	(	Builder &	builder,
		ArrayRef< char >	elfData
	)

Returns a map containing the amdhsa.kernels ELF metadata for each of the kernels in the binary, or std::nullopt if the metadata couldn't be retrieved.

The map associates the name of the kernel with the list of named attributes found in amdhsa.kernels. For more information on the ELF metadata see: https://llvm.org/docs/AMDGPUUsage.html#amdhsa

◆ getKernelMetadata()

gpu::KernelTableAttr mlir::ROCDL::getKernelMetadata	(	Operation *	gpuModule,
		ArrayRef< char >	elfData = `{}`
	)

Returns a #gpu.kernel_table containing kernel metadata for each of the kernels in gpuModule.

If elfData is valid, then the amdhsa.kernels ELF metadata will be added to the #gpu.kernel_table.

◆ getROCMPath()

StringRef mlir::ROCDL::getROCMPath ( )

Searches & returns the path ROCM toolkit path, the search order is:

The ROCM_PATH environment variable.
The ROCM_ROOT environment variable.
The ROCM_HOME environment variable.
The ROCM path detected by CMake.
Returns an empty string.
