SiFive cores with MAL-9092 require fence.rw instructions around HLV/HLVX/HSV hypervisor instructions to ensure proper memory ordering when accessing guest memory. Note that HSTATUS.HU is cleared during KVM initialization, restricting hypervisor instructions to HS-mode only. If future changes enable HSTATUS.HU for U-mode access, additional errata considerations will be needed.
