Motivation

TensileLite YAML solution files and CustomKernel assembly files contained parameter type mismatches (e.g., int where bool is expected, int where float is expected). Because msgpack serializes bool and int as different wire types, these mismatches cause std::bad_cast at runtime.

The existing build-time check only emitted a warning, allowing broken files to ship silently.

Changes

Fix all existing type mismatches

Corrected types across hipblaslt library YAML, hipblaslt test YAML, hipblaslt CustomKernels (.s), and hipsparselt library YAML:

Conversion	Parameters
int → bool	BufferStore, ExpandPointerSwap, LDSTrInst, MIArchVgpr, NoReject, PreloadKernArgs, SourceSwap, StorePriorityOpt, TailloopInNll, Use64bShadowLimit
bool → int	DirectToLds, DirectToLdsMetadata, SwapGlobalReadOrder, TransposeLDSMetadata, UsePLRPack
int → float	GlobalReadPerMfma
float → int	StaggerUStride

Promote type mismatch warning to hard error

printTypeMismatchSummary() in TensileCreateLibrary/Run.py now raises RuntimeError when mismatches are detected, failing the build immediately instead of continuing with a warning.

Fix GlobalReadPerMfma default type

Changed the default value in GlobalParameters.py from [1] (int) to [1.0] (float) so inherited defaults don't trigger the type check.

Test Plan

• Verified zero remaining type mismatches via device library build for gfx942 (2456 YAML logic files checked clean)
• Updated test_validateParameterTypes.py to assert RuntimeError is raised on mismatch detection
• Existing unit tests pass with all fixes applied

Risk level

Low — the YAML/assembly fixes are purely data corrections (values semantically unchanged, just typed correctly), and the hard error only triggers on genuinely broken files that would already fail at runtime.
