◆ addElementwise()

SmallVector< OpFoldResult > mlir::xegpu::addElementwise	(	OpBuilder &	builder,
		Location	loc,
		ArrayRef< OpFoldResult >	lhs,
		ArrayRef< OpFoldResult >	rhs )

Generates element-wise addition ops of two arrays with same length.

◆ addWithRightAligned()

SmallVector< OpFoldResult > mlir::xegpu::addWithRightAligned	(	OpBuilder &	builder,
		Location	loc,
		ArrayRef< OpFoldResult >	lhs,
		ArrayRef< OpFoldResult >	rhs )

Generates element-wise addition ops of two arrays with automatic alignment.

When the input arrays have different sizes, the shorter array is right-aligned with the longer array, and the unmatched leading elements from the longer array are preserved unchanged. This is commonly used for offset computation where higher-dimensional offsets need to be added to lower-dimensional adjustments.

Example: lhs = [l1, l2, l3], rhs = [r1, r2] Result: [11, l2+r1, l3+r2]

◆ doSCFStructuralTypeConversionWithTensorType()

void mlir::xegpu::doSCFStructuralTypeConversionWithTensorType	(	Operation *	op,
		TypeConverter	converter )

Do type conversion for SCF structural ops, e.g., scf.for using SCF structure type convertion patterns.

Since VectorType cannot carry the layout attribute, which is needed to guide the type conversion for XeGPU, they are first converted into RankedTensorType, where the layout attribute can be attached. And then upstream SCF structural type conversion patterns are applied with the provided converter. TODO: This is a temporary solution. We should refactor it when context-aware type conversion is available.

◆ getDistributedVectorType() [2/2]

FailureOr< VectorType > mlir::xegpu::getDistributedVectorType ( xegpu::TensorDescType tdescTy )

If tensor descriptor has a layout attribute it is used in SIMT mode.

In this mode, the distributed vector shape is determined as follows: Definitions: lane_data_size = lane_data[0] × lane_data[1] subgroup_size = lane_layout[0] × lane_layout[1] distribution_unit_size = subgroup_size × lane_data_size

Case 1: Regular loads/stores. The following conditions must be met:

tensor_desc[0] == lane_layout[0] Distributed vector is a 1D vector with shape: [chunk_size]

Case 2: Block loads/stores Additional definitions: tensor_size = tensor_desc[0] * .. * tensor_desc[r-1] * array_length n_distribution_units = tensor_size / distribution_unit_size fragment_size = n_distribution_units * lane_data_size Given above definitions, the following conditions must be met:

tensor_desc[0] % (lane_layout[0] × lane_data[0]) == 0
tensor_desc[1] % (lane_layout[1] × lane_data[1]) == 0 Distributed vector is a 1D vector with shape: [fragment_size]

◆ populateXeGPUUnrollPatterns()

void mlir::xegpu::populateXeGPUUnrollPatterns	(	RewritePatternSet &	patterns,
		const UnrollOptions &	options )

Collect a set of patterns to unroll xegpu operations to a smaller shapes.

Users can control whether an operation to be unrolled or not, as well as its target shape via options structure. (via setting filterConstraint and nativeShape respectively, both of them are function refs taking op as input). An op is unrolled to the targetShape as follows, for each of its operands:

the unrolled type unrolledType and number of unrolled instances numUnrolledInstances are computed from the targetShape.
pack each operand. ExtractStridedSlice are created to break-up the vector operands. And BuiltinUnrealizedCastop are created to break-up the TensorDesc operands.
the original op is cloned numUnrolledInstances times, once for each result.
unpack the results. InsertStridedSlice are inserted for VectorType result, and BuiltinUnrealizedCastOp are inserted for TensorDescType result to re-assemble the slices into the original shape.
