The OpenSBI firmware is one of the most widely used M-mode runtime firmware in RISC-V world. This firmware provides Supervisor Binary Interface (SBI) and various other services to the S-mode software. This talk will focus on the OpenSBI domain support which was added to the OpenSBI project recently in v0.9 release. The OpenSBI domain support helps users achieve system level partitioning using RISC-V features (such as PMP) and it can be easily extended to use upcoming RISC-V features such as ePMP, IOPMP, etc. This talk will also include a small demo showing a small trusted bare-metal application running in it's own domain along with Linux running as separate domain.
