Function core::core_arch::riscv_shared::hinval_gvma

pub unsafe fn hinval_gvma(gaddr: usize, vmid: usize)

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

Invalidate hypervisor translation cache for guest physical address and virtual machine

This instruction invalidates any address-translation cache entries that an HFENCE.GVMA instruction with the same values of gaddr and vmid would invalidate.

This fence specifies a single guest physical address, shifted right by 2 bits, and a single virtual machine by virtual machine identifier (VMID).
