Finding Common Ground - the Boot and Runtime Services (BRS) Specification
summary
A RISC‑V Boot and Runtime Services (BRS) spec defines OS‑observable boot and hardware description so one install image can boot on multiple vendors’ PCs and servers. It defines two profiles BRS‑I (interoperable) and BRS‑B (bespoke), targets a RV20 64‑bit baseline, and reuses UEFI, ACPI and device tree conventions. A compliance suite forks ARM’s BBR ACS, runs FWTS and UEFI tests on QEMU+OVMF; UEFI system tests hit about 75% passing today, ACPI coverage and more tests are still in progress.
