Concise monthly summary for Aug 2025 focusing on features and bugs delivered for tenstorrent/tt-exalens. Key work included Blackhole register file I/O and dump_regfile enhancements enabling 32-bit formats read from destination memory, expanded format support (uint16, int8, uint8, uint32 for Blackhole; uint16 for Wormhole), tile-count option, and TILE IDs; plus capability to write data to the destination register file for 32-bit (Int32, UInt32, Float32) and 8-bit formats with comprehensive tests. A bug fix updated debuggable core detection for RISC processes by using risc_debug.can_debug(), resolving display issues in GDB. Overall, these changes strengthen debugging and data manipulation workflows in TensixDebug on Blackhole and improve core reliability, contributing to faster iteration and higher-quality data inspection.

July 2025 performance highlights: Strengthened debugging reliability and developer productivity across tt-exalens and tt-umd. Key features include robust RISC PC retrieval (get_pc) with a unified RiscDebug class and caching; GDB server usability and core-type reporting improvements with cleaner labels, HEX formatting, and error handling; private memory access enhancements for RISC cores; enhanced ELF symbol handling with symbol-table addresses/sizes and a new ElfDwarfSymbol; and YAML-based serialization for tt_SocDescriptor via UMD, aligning configuration export with modern tooling. Notable fixes include addressing unaligned Blackhole reads/writes and related private-memory warnings in TRISC2 to reduce debugging noise. These changes improve reliability, reduce triage time, and enable easier cross-repo configuration management.
