Function riscv::asm::sfence_vma_all

pub unsafe fn sfence_vma_all()

SFENCE.VMA instruction wrapper (all address spaces and page table levels)

Synchronizes updates to in-memory memory-management data structures with current execution. Instruction execution causes implicit reads and writes to these data structures; however, these implicit references are ordinarily not ordered with respect to loads and stores in the instruction stream. Executing an SFENCE.VMA instruction guarantees that any stores in the instruction stream prior to the SFENCE.VMA are ordered before all implicit references subsequent to the SFENCE.VMA.
