Hi,
On a Stage-2 page fault, Hafnium does not report FAR_EL2 to FAR_EL1 in inject_el1_exception .
As a consequence EL1 is resumed although it cannot determine the faulting address from FAR_EL1 (which likely holds zero or some other remnant value?).
Is this intended?
That sounds like a bug.
Fuad, did you work on this? Any idea what's going on here?
(Note, Fuad is away this week but can hopefully reply next week.)
It is a bug, an oversight on my part. I'll post a patch.
Cheers, /fuad
