December 2025 monthly update for ROCm/tensorflow-upstream: focused on stabilizing the quantized uint8 path in the MLIR-to-TOSA conversion by delivering a critical bug fix and test coverage improvements. Implemented robust error handling in the TosaConvertTFLUInt8 pass to abort on tosa.const with quantized uint8 values, preventing silent mis-conversions. Updated tests to validate ui8 attribute handling and aligned changes to avoid regressions. This work enhances model reliability and predictability in quantized deployments, with traceability to commit 4c6f6242d0901eb4e152efd76dde5dc2227612cc, and demonstrates proficiency in MLIR, TOSA passes, quantization, and test automation.
