addAsyncDependency()

void mlir::gpu::addAsyncDependency	(	Operation *	op,
		Value	token
	)

Definition at line 612 of file GPUDialect.cpp.

getDefaultGpuBinaryAnnotation()

std::string mlir::gpu::getDefaultGpuBinaryAnnotation

(

)

Returns the default annotation name for GPU binary blobs.

Definition at line 35 of file SerializeToBlob.cpp.

getHardwareIdForMapping()

static Processor mlir::gpu::getHardwareIdForMapping ( MappingLevel  level, int  dimension  )

static

Computed the hardware id to use for a given mapping level.

Will assign x,y and z hardware ids for the first 3 dimensions and use sequential after. TODO: Make this use x for the inner-most loop that is distributed to map to x, the next innermost to y and the next innermost to z.

getMappingAttrName()

StringRef mlir::gpu::getMappingAttrName

(

)

Name of the mapping attribute produced by loop mappers.

mapParallelOp()

static void mlir::gpu::mapParallelOp ( ParallelOp  parallelOp, MappingLevel  mappingLevel = MapGrid  )

static

Add mapping information to the given parallel loop.

Do not add mapping information if the loop already has it. Also, don't start a mapping at a nested loop.

operator++()

static MappingLevel& mlir::gpu::operator++ ( MappingLevel &  mappingLevel )

static

Bounded increment on MappingLevel.

Increments to the next level unless Sequential was already reached.

setMappingAttr()

LogicalResult mlir::gpu::setMappingAttr	(	scf::ParallelOp	ploopOp,
		ArrayRef< ParallelLoopDimMappingAttr >	mapping
	)

Sets the mapping attribute of a scf.parallel operation.

Verifies that the mapping passed is valid.

• the number of DimMapperAttr provided is same as the number of loops of the ploopOp.
• the mapping does not map multiple loops to the same processor.

transformGpuModulesToBinaries()

LogicalResult mlir::gpu::transformGpuModulesToBinaries	(	Operation *	op,
		OffloadingLLVMTranslationAttrInterface	handler = nullptr,
		const gpu::TargetOptions &	options = {}
	)

Searches for all GPU modules in op and transforms them into GPU binary operations.

The resulting gpu.binary has handler as its offloading handler attribute.
