Linux Kernel Continues Prepping For RISC-V’s Updated Supervisor Binary Interface

993

RISC-V’s Supervisor Binary Interface “SBI” is the interface between the platform-specific firmware and the running operating system or hypervisor for interacting with the supervisor execution environment in the higher privileged mode. The Linux kernel has been working to support a newer version of the SBI that is more extensible moving forward.

The RISC-V Supervisor Binary Interface v0.2 now has extendability in mind with the ability to add extensions in the future while maintaining backwards compatibility. Linux kernel patches continue to be worked on in supporting this updated SBI interface for the Linux kernel.
