*status.MXR Control

[xusq123]

In VS mode with two-level translation enabled, g_stage leaf pte.xwr=100, mstatus.mxr=0, writing sstatus.mxr in VS mode makes vsstatus.mxr=1. Should executing a load trigger a load guest fault?

[ved-rivos]

The HS-level MXR (mstatus.MXR) bit makes any executable page readable. vsstatus.MXR makes readable those pages marked executable at the VS translation stage, but only if readable at the guest-physical translation stage. In your example, the HS-level MXR is 0 and the load in question will lead to a load guest-page fault.
