Function core::arch::riscv64::hinval_gvma_gaddr

pub unsafe fn hinval_gvma_gaddr(gaddr: usize)

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

Available on RISC-V RV64 and (RISC-V RV32 or RISC-V RV64) only.

Invalidate hypervisor translation cache for guest physical address

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; the physical address should be shifted right by 2 bits.
