Expand description
Hypervisor memory management fence for all guest address spaces and guest virtual addresses
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.VMIDhas the same setting as it did whenHFENCE.VVMAexecuted.
This fence applies to any guest address spaces and guest virtual addresses.
