RISC-V ACPI Is Ready for Server Platforms

on YouTube ↗18m

" summary

Three and a half years of specification work delivers a ready stack: ACPI updates land as ACPI 6.6, Linux 6.2 and QEMU 9.1 already carry patches, and EDK2 + OpenSBI integration boots Linux in the demo. New RISC‑V tables include RHCT (ISA/CPU capabilities) and a draft RIMU for IOMMU topology, FFH is ratified for power/FFH registers, SPCR and SRAT/NUMA are updated, LPI and CPPC power control work via SBI calls, and a RAS error‑record path with an OpenSBI agent is implemented.
