The SBI V2.0 and Beyond
summary
SBI v2.0 finishes public review and targets ratification by year end, adding concrete extensions: power management (HSM, system suspend, CVPC) to coordinate M/HS state, virtualization features that give guests accurate preemption accounting and lower trap overhead, and platform services (system reset, debug console, CPPC). Nested virtualization uses a nested-accel shared-memory mechanism to cut trap rates; timing-sensitive VMs use steal-time accounting to see lost CPU time; a KVMUnit test suite is under development to validate POC implementations across bare-metal and virtualized stacks.
