本文主要介绍了RISC-V BRS规范的合规性测试。随着RISC-V实现数量的增加,需要一种标准化的方法来确保不同RISC-V平台之间的兼容性。RISC-V BRS规范定义了基于SBI/UEFI/ACPI/SMBIOS/DT等的一些引导和运行时服务要求,系统软件可以依赖这些要求。RISC-V BRS测试套件基于UEFI-SCT和FWTS测试套件,用于检查RISC-V平台与BRS规范的一致性。目前,RISC-V BRS规范已经进入冻结阶段,预计在2023年第四季度完成认证阶段。在RV64 Qemu Virt平台上,UEFI-SCT的测试通过率约为85%,而FWTS的测试通过率约为70%。文章还提到了在ACPI表、UEFI安全启动等方面存在一些关键差距,并呼吁社区参与讨论和协作,以加速为RISC-V架构提供开源软件。
