Function core::arch::riscv64::hfence_vvma_vaddr

pub unsafe fn hfence_vvma_vaddr(vaddr: usize)

🔬This is a nightly-only experimental API. (stdsimd #27731)

Hypervisor memory management fence for given guest virtual address

Guarantees that any previous stores already visible to the current hart are ordered before all implicit reads by that hart done for VS-stage address translation for instructions that:

• are subsequent to the HFENCE.VVMA, and
• execute when hgatp.VMID has the same setting as it did when HFENCE.VVMA executed.

This fence specifies a single guest virtual address.
