Linux on RISC-V with Open Hardware

Explore the world of RISC-V architecture and its integration with Linux in this comprehensive conference talk. Delve into RISC-V's global presence, including virtual meetups and the RISC-V International organization based in Switzerland. Understand the essential documentation for electronics, including schematics and board layouts. Learn about the Instruction Set Architecture (ISA) and its role as the interface between hardware and software. Examine RISC-V's base and standard extensions, as well as its privileged architecture with three privilege modes. Discover OpenSBI, an open-source SBI implementation, and its importance in avoiding fragmentation. Investigate RISC-V's implementation in the Linux kernel and explore various hardware platforms, including the SiFive Freedom Unleashed and Microchip Icicle board. Gain insights into open-source FPGA toolchains and the Team Linux on Badge project. This talk provides a thorough overview of RISC-V's open hardware ecosystem and its growing importance in the Linux community.
