Commits include 43751f2... and related test infra updates; removed single-tile output constraint. - Enabled Quasar TRISC3/SFPU path in tt-metal: added SFPU linker script, mailbox handling, perf counters, dynamic TRISC count, and SFPU tests with a stub to ensure testability in non-SFPU scenarios. - Introduced SFPU testing enhancements and reliability improvements in Quasar: isolated SFPU square path tests, extended Python helpers and test headers, and guard fixes to ensure stable initialization. - Reverted BRISC polling/Quasar compatibility regression to restore pre-#1504 polling behavior, maintaining test stability in Quasar environments. - ND/trisc3 quasar test infra fix: addressing test reliability for Quasar TRISC3 paths; improved test setup consistency. Major bugs fixed (2-3): - Stimuli generation and per-tile golden comparison bugs for multi-tile matmul were fixed, enabling accurate multi-tile validation. - BRISC polling regression reverted to maintain Quasar test stability and prevent timeouts in commit/elf-based tests. - Test infra adjustments for ND and TRISC3 paths to avoid flaky test runs. Overall impact and accomplishments: - Expanded compute capabilities for Quasar with SFPU support and a configurable TRISC count, enabling broader workloads and better throughput. This positions TT hardware/software for higher-density compute scenarios and more robust performance validation across matrix operations. The test infrastructure enhancements reduce flaky test results, accelerating CI feedback and reliability for hardware-path features. Technologies/skills demonstrated: - Low-level hardware-software integration (SFPU, TRISC, linker scripts, perf counters) and test infra work. - C/C++ kernel/test code, test harnesss, and Python-based test configuration utilities. - Multi-tile tiling concepts, stimuli generation, and golden data validation across tiled outputs. - Cross-repo coordination and release hygiene for feature parity and regression safety.
