RISC-V Summit

The Performance Analysis SIG works to improve the state of performance analysis on RISC-V systems, by overseeing both the development of new ISA extensions to improve visibility, and the enabling of the software ecosystem (firmware, OS, tools). In this talk, chair Beeman Strong and member Atish Patra will recap the work completed in the last year, including 4 new ISA extensions and several improvements to Linux perf, and introduce some ongoing work. This will include progress updates on the Performance Events TG, the Performance Event Sampling TG, the Self-hosted Trace TG, and further Linux kernel/perf tool enhancements that aim to allow performance analysis on RISC-V to match or exceed the experience on competing ISAs.
