OS-A SEE Explained
summary
OS‑A SEE defines a Supervisor Execution Environment interface for RV64 application processors that maps bootloader and kernel calls into firmware or hypervisor services, aiming to let one binary run across profiles (example targets: RVA20, RVA23). It standardizes boot/runtime tables and services (power/pstate, driver loading) via existing specs like UEFI, Device Tree, ACPI and SBI extensions, plans a conformance test suite and platform requirements work in 2023 to produce compatible binary distributions.
