Function core::arch::riscv32::sfence_vma

pub unsafe fn sfence_vma(vaddr: usize, asid: usize)

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on RISC-V RV32 only.

Supervisor memory management fence for given virtual address and address space

The fence orders only reads and writes made to leaf page table entries corresponding to the virtual address in parameter vaddr, for the address space identified by integer parameter asid. Accesses to global mappings are not ordered. The fence also invalidates all address-translation cache entries that contain leaf page table entries corresponding to the virtual address in parameter vaddr and that match the address space identified by integer parameter asid, except for entries containing global mappings.
